I have been looking at building a boat for a bit now, I am looking at the Vagabond 20' or 23' as a trailer sailor, large enough for a weekend sail with the kids and small enough to haul.
If so what did you find challenging about the build or what improvements would you suggest? Location: Australia It might be a bit too sporty for your requirements but a current design for home building that is gaining momentum is the i550. Nice looking craft, I'll take it into consideration ,and review it today, I appreciate your replies, good budget to build as well I see. That said a 20-25 ft is a great size and trailerable, although I can set a mooring at his place and not have to worry about the trailering so much.

Best, Stan I agree rosorinc that is a beautiful boat, and thanks for the post, I have a issues of the woodenboat magazine and they have a nice weekender in the latest issue.
Location: New Brunswick, Canada I really appreciate the input from everyone, it is reassuring that a boat build is in my future and to have the many folks here to pick their brains. I am relatively new to the entire nautical lifestyle, enjoyed a few boats in my youth, and enjoyed learning to sail and am so excited to get a build going! I hate to be the devil's advocate here, but building a boat is a big commitment in terms of time, money and effort.
We have been sailing as the crew on the Allyance,(brother-in-law's) a 27ft Hunter, for a few summers now, and both my wife and I love it.
I have the full support of my wife on the build (as long as the other regular house maintenace doesn't go slack LOL).
I really liked a lot of the reasons behind the CLC Pocketship as detailed in the Woodenboat article and on the CLC website. I am now on my THIRD build and i know it sounds absolutely CRAZY that i started another small build in the middle of my big build, but what i learned this time around will save me MANY hours of time further down the line. The learning curve is endless and i can now absolutely prove it - that by building a small dinghy first, you do save time and money. When making potentially dangerous or financial decisions, always employ and consult appropriate professionals.
Boat Building Academy student Ian Baird’s project to build a replica of the rare Dorset crab and lobster boat known as Witch of Worbarrow during his course is continuing apace, as it must to be be ready for the big launch on the 9th December. Ian, who was a novice woodworker at the beginning of his nine month course at the BBA, has been commissioned to write three articles on his experiences for Watercraft Magazine.
The launch of the BBA’s March 2010 project boats will take place in the harbour at Lyme Regis, Dorset, at 9am on Wednesday 9th December 2010. Have you got news for us?If what you're doing is like the things you read about here - please write and tell us what you're up to.
Classic Sailor is a new magazine about traditional and classic boats from ex-Classic Boat editor Dan Houston and colleagues that promises rather more coverage of the traditional craft around our coast.

Our Faversham-based friend Alan Thorne can help with boatbuilding projects - constructing to plans in very tidy stitch-and-glue or more traditional techniques. Location: Samogitia Build of small mahogany sailboat with water jet propulsion I began to build a mahogany boat with water jet drive and and own design wingsail. Using AutoCAD I tried to design a boat hull somewhat similar dinghy, yachts and powerboats hulls. My disposal I have a woodworking shop, CNC machining center, stainless steel welding equipment, AutoCAD using experience, joiners tools and experience. Well, I still think I can build this boat and am looking forward to constructive criticism from you. Location: Samogitia Few pictures of boat building process CNC machined and assembled form for machogany boat build. Location: France Man, it's already looking very good - specially when you say you have no experience with boat building. Location: Eustis, FL You don't really think that's anything close, to a reasonable set of sailing lines do you?
If honestly I think that for better sailing lines need more boat wide, smaller transom and may be deeper keel. Location: Samogitia More of boat building process Showed that the first layer will not be easy to put correctly on the curved boat hull form. Trying to resolve the situation with the springy rubber hose pieces pierced with wire hooks.
The second layer of mahogany cross diagonal bands is finished and sanded for outer 2,5 mm layer gluing.

As I point out in my book, people often fail to differentiate between resale value and resale price.
The fact that McNaughton is too dense to comprehend basic geometric principles has nothing to do with structural reality.
The picture above is of wooden planking ,which has no strength across the planks , which is exactly what frames were developed for.
There is nothing floppy about a finished origami hull.Such comments reveal an absolute naivety about the subject. As for the cost beatup, you were asked before just how much it would really cost on another thread (in time and dollars) to add 5 or 6 transverse bar frames to a 36 foot steel boat. Nobody said that origami hulls are floppier, they are just weaker becasue the framing is floppier than a conventional frame.
But you need to accept that some of your reasoning doesn't scale well to larger boats with much higher loads. Location: British Columbia Points 1 and 2 apply equally to longitudinals, as they are equally supported by their being welded to the hull plate, with the added structural advantage of going around a curve, yet you insist on calculating them as stand alone, with no attachment to, or support from, the hull plate. It doesn't cost much to put 6 transverse frames in a hull, once it has been pulled together using origami methods, altho I know one guy who turned a couple of frames into a several week project, to increase his total income for the job.The point I am making is, if you put the frames up first, then try put the plate on to fit the frames, the cost and time goes up exponentially.

The relevance of frames is quite necessary to make the whole ship an almost corrugate systeme, with all the strength in all the direction. Now when the round plate is transformed in chine on your design, you have an intense stress point there, and that is no good practice.
As for your other boat, they all are ceiled in wood inside and seams to cost much more that a Swan. Fisherman and commercial are tough with the money, every cent is acconted, but you don't know that. By the way I would like to mention, a vessel of a certain size is never ever designed by one person, same for building.


We may argue about his biased opinions, about his terribly obvious lack of understanding some basic engineering, but we cannot argue that he does it to harm or insult other members.
I know there are visitors here which cannot really get it together, where is the knowledge and where the anecdote.
Reverse clipper bows and wine glass cross sections would be difficult but practically any other single and multi chine hull form can be done in origami.
It's clear that the longitudinals go into tension, suffer stress reversals and consequently deflect more that a pre bent frame. Originally Posted by whoosh … do these boats come with lines, as iines if one wanted to draw a body plan, for tankage floors frames etc? That can be done by the software, or you can build chine model and take the strakes patterns from it..
Originally Posted by dskira When I designed and latter on built (sorry, I built too, but that is not relevant since you want to be the only one here) if we don't put frames the vessel will have been not able to do its work properly due to wickness, let alone having the cargo capacity strength needed to pay for itself and being safe.
Daniel As I only build one hull a year, a couple of weeks work, and on every on I work with the owner, who's lifelong dreams are coming true , quickly before his eyes, it never gets boring. The end of the chine where the cone begins is solid plate once the chine ends, not weld, so one is not dependent on the weld for strength. Where Paul's mast goes thru the deck, a large doubler of heavier plate, plus some flat bars on edge eliminates the chances of anything wobbling .
The only compression on the mast is only the weight of the mast, rigging and sails on a junk rig , unlike the tremendous compression on a marconi rig. Colvin estimates 1,000 hours for a hull and deck, something origami lets you do put together in under 100 hours. As I pointed out in the cabin top example, a curve drastically increases the stiffness of a piece of plate .
None of my boats have ever had problems getting insurance at the best rates, or passing survey. Originally Posted by Brent Swain None of my boats have ever had problems Hope it will stay that way.
Location: British Columbia I have made wineglass sterns by welding the last few inches of centreline first, before cranking the deadrise out with the hydraulic jack.
As Herreschoff pointed out , in smaller boats, clipper bows tend to stop a boat dead in her tracks when they hit a steep head sea. Many of my hulls have saved their owners from the disasters which would have resulted in most other cruising boats out there. The hull will need a lot of framing following on from that picture and I'm skeptical that in the long run with a vessel that size it might just re-allocate the build time.
Roberts has a method which is said to be fast, its bottom plate then framing then the rest built bottom up. No matter if you have never built a thing in your life or if you are a woodworking genius, it’s easy to design a boat if you have the proper boat building plans.
The most important thing you will need to build your own boat is a workshop, garage, or a place to build it. Since this is something you have complete control over, let your mind run wild as you start with your boat building plans. The great thing is that you really don’t require any woodworking guru skills to build your own boat as long as you have detailed enough boat building plans.
Building a boat is one of the most rewarding projects you can do to create something beautiful and useful for years to come.
See how we built a 20ft trailered houseboat that can be used on the water and as a camper along the way. If you’re dead set on building a Dory Boat, these are hands-down, the best dory plans you will find on the internet. The most comprehansive boat design package ever made with all the boat building basics to help you get started immediately. Located in historic downtown Wilmington, North Carolina along the Cape Fear River, CFCC’s boat building school offers two programs designed to teach students the fundamentals to work in the boat building and repair industry.
Emphasizes fiberglass and composite boat building techniques along with training in marine finishes and paints, marine electrical, plumbing and rigging systems.
Focuses on traditional woodworking skills and precise wood joinery techniques needed to work in boat building or woodworking trades.
Location: San Francisco Boat building workshop I am hosting a four day hands-on boat building workshop in my backyard in San Francisco.
Location: Tasmania,Australia Its a great twist that Derek has - get paid to design a boat, then get the builders to pay for the privilege of building it too. I would like to hear from any Kelsall design builder who actually finished a boat without Derek being on site to supervise the KSS method.
Location: San Francisco Actually, when Derek holds a workshop the builder, who is usually building his own boat, gets all kinds of free help as the class works on part of their boat and Derek is onsite to answer questions that come up, both of which benefit the builder.
Also, this design is not a Kesall design - it is a resurrected Micronesian design from hundreds of years ago.

I have been a fan of his work since his first plywood designs, and his innovative work in plywood.
Location: San Francisco The 47 foot Chamorro Flying Proa that we built using redwood took two years to build and cost about $20k just for materials, and that was in California, not in the Marianas where it would have cost three times as much.
Now that we've built the proa it has become a cultural treasure - it is the first one in over 250 years.
We consider that if we can teach the younger generations how to build and sail again and if we can get 500 Chamorro Flying Proas on the water at the same time once again, that we will have recovered our maritime tradition.
Our plan to get to 500 proas is to build three canoe houses - one on Guam, one on Saipan and one in San Diego where there is a large Chamorro community. I also suspect that foam and glass will survive longer than timber in the marine environment, which would make it good value. Even so, have you done the detailed costing of marine plywood ( not timber ) with say epoxy ?
If you want to teach people to build boats, plywood is by far and away the easiest technique - especially if you want to get 500 + boats in the water.
Location: Duluth, Minnesota Cool, i dont know how i didnt know that, i learnt something today.
Location: Tasmania,Australia Yes, he may have started early on foam, but not exclusively since the 60's by any means.
I am still curious if you have actually done the costing between ply and foam, considering you have so many boats you want to get in the water.
The pic Im thinking of has two heavy unrigged clinker rowed boats on the beach and I think a group of women with nets and fish baskets, I have a print here, somewhere but cannot find it.
Try scrolling down, clicking on the 'older posts' button at the bottom of this page - or try the search gadget! The most importantly - the boat will have to be small and beautiful, will have low weight that I can carry it on my car's roof. I've watched many boats images as shown on the internet and I have not bad joiner experience.
So make up such a frame for a 40 footer, and I can bend it by hand, by simply putting one end against the wall and pushing on it.


By itself, it is as floppy as hell, but once it is tacked down, with a 7 inch camber, with no structural members under it, six guys can stand and jump on it, without it buckling or deforming in any visible way.
It will first twist the plating, second will wooble the deck, and third the mast will go thru the hull. I thought you knew that, but evidently you don't, since your very mean attack on my resume prove it. There, a dumb welder with insufficient and outlasted licenses can blame a well established boatbuilder of being a novice.
Their excitement , and enthusiasm in seeing a hull take shape in a few hours from flat plate, is contagious. You could just go to the sporting goods store and buy yourself a great boat, but it will be one of those soulless, plastic, mass produced things that will never give you the pride of knowing you actually built it with your bare hands out of a stack of wood.
Once you have this and a good set of starting plans, the rest just comes down to having a few basic woodworking tools and after a few weekends, you will be cruising around in your brand-new, hand-made, wooden boat.
More than anything, you are going to want some basic plans so you will have a grasp on how the whole thing comes together.
Think of all the details that will make your boat unique and something that no one else has. If you already have the skills, the shop and great equipment, then you already know that building chairs all day is fun, but building your own boat will be the most satisfying thing you will do as a wood worker.
You can download boat designs today, read through them tonight, and after a trip to buy some supplies, you could be make the first cuts to building a boat by tomorrow. This software automatically does all the calculations to help your boat cut through the water. The programs focus on hands-on training in traditional and modern boat construction, repair, and mechanical system maintenance.
The builder asks Derek to host a workshop, not the other way around, and the builder doesn't pay for the workshops. The traditional material was the wood from breadfruit trees that were abundant on the islands, but it is not available today due to loss of undeveloped land and the greatly increased instances of super-typhoons in the last 20 years that knock down the taller trees. The fact that the material isn't wood is not ideal, but on the other hand the Chamorro flying proa is a Chamorro invention and the design is unique in the world, so we reason that whatever material is used, it is a Chamorro proa. The idea is that anyone who wants to build a flying proa can just pay for the materials and go to the canoe house to use the table, tools, etc. I know he has been doing foam core cats and tris since Toria in the 60s, one of of not the earliest foam core multies.
Building a current design with a growing fleet might be a cheaper option as the resale value will be better.
Resale value is the difference between what you can get for a boat and what she cost you in the first place. The attached framing limits damage and provides safe stress paths which is not only a strength and stiffness issue but also a fatigue issue. Since your method of framing is floppier for being pre-stressed then the hull structure will buckle more easily.
It does develop soft spots once the longitudinal welds are done , which is why I force flat bar beams up under it, on 18 centres , along the direction of the curve, like longitudinals , not fore and aft, across the curve , like transverse frames.
The deck is weakest point, the design need more attention since some renforcement can be detrimental localizing the stress inset of diffusing it. Really, how would I be able to make something as cool as a wooden boat and not have it sink or leak all over the place? Once you understand how to seal all of the seams together and how to properly brace your boat so it’s not flimsy, then the only limitation when you design a boat is how to get it out of your garage.
The best part is that since you are not dropping thousands of dollars on a factory made boat, you can now afford to make the boat you build bigger and better than you thought you could afford.
And when you see your boat out on the water and everyone’s checking it out, you will know that your skills built that boat.
Depending on your dedication and how complex the boat design is, you could be hanging out in your very own boat within a month.
Graduates will have the skills needed to work for companies in boat building, boat repair or woodworking.
The one in San Diego, with a make-shift tarp sail that is only 70% of the proper size has hit 15 knots.
Andrews NB or Grand Manan, but for the most part as mentioned before mostly river sailing. I know how to swing a hammer and how to cut wood, but how would those “hobbyist level” skills actually translate to building a boat that floats?
Now I have something great to focus on and by this time next year, I’ll be cruising around on a boat I build completely myself! This proa is currently in the San Diego Maritime Museum, on the water until the end of July. We will build a 25 foot proa hull and outrigger and there will be demonstrations of how to build catamaran hulls.
The reason for that number is that in the old days, in the 1600s and 1700s, Europeans arriving in the islands reporting seeing hundreds of proas on the water. I Rubbed the hull with epoxy resin, with six hand-help put fiberglass and dip the cloth by epoxy. It's not how much material you put in a structure that makes it effective, it's where you put the material.
Highest strake stays in one piece, lower strakes are cut in the middle and ends of the plates are connected. My current boat, with about three inches of outside curve , goes thru a head sea far more smoothly, with far less resistance.The buildup of buoyancy is far less sudden. Now we want to build more using modern materials that are less expensive and for this we have chosen the KSS method of foam resin infusion (foam infused with polyester resin sandwiched between two layers of fiberglass using vacuum bagging).
Any material has to be shipped in and foam, resin and glass is much cheaper to ship than wood due to the weight and container space. And now it's too late to correct boat hull problems because, sadly but the hull is finished. Very nervous job.Will need to apply extra two layers of fiberglass without for preparing to warnish. The deck is weakest point, the design need more attention since some renforcement can be detrimental localizing the stress inset of difusing it. The cost for the four day workshop is $750 for the entire workshop and includes coffee and lunch each day. The sailing tradition was completely lost during Spanish colonization when the Chamorro population dropped from 80k to 2k people due to disease and war, and the Spanish forced all the Chamroros off the 14 northern islands and onto Guam where they were forbidden to build proas or even to sail off the reef.
So you can get a reduced puncture resistance if you want, but I'd still put the required framing in. If you've never built anything out of fiberglass, this workshop will give you the practical skills and knowledge to build a boat. It is where you put the material ,and for puncture resistance, it's best put in plate thickness.
