Location: Marshfield massachusetts usa designing a fast rowboat I live in New England (USA) and we have a growing sport of open water ocean rowing racing. Location: Lake Michigan I don't claim to be an expert, but for speed, little to no rocker is good. A race boat would have to be longer (the longer the better) and a bit wider (but not much wider). Location: Cornwall, England Take a look at a gig, they don't come any faster or sweeter (but I'm biased, we've raced 'em in Cornwall for the past couple of hundred years!
Location: Eustis, FL Build her light and put some foils on her, so you can spank the fleet. Location: Marshfield massachusetts usa Safewalrus, We have the gigs here too.
Location: Marshfield massachusetts usa Terhohalme, Very interesting piece of work, I'd be interested to find out more about your boat.
Location: Trondheim, NORWAY I think you could try minimum wetted surface, long waterline and optimize the Cp for your speed.
Location: Marshfield massachusetts usa Safewalrus, That Flashboat, VERY interesting can you point me to plans? Length must be an important part of the speed equation,a long narrow boat will always be faster than a short wide one. 1 ) A fast rowboat will probably be as long as possible and because of its length will be able to have as narrower beam as permitted by the required displacement.
Bow steering ,yes like you guys I am concerned about bows digging in and directing the issue.
There must be a point where the trade off between wave making and wetted surface is at an optimum.. When making potentially dangerous or financial decisions, always employ and consult appropriate professionals.

I agree with it looking an awful lot like Wally, plus the bow of that ship is awfully dangerous in case it hits a wave it would probably flip itself.

I am looking for information with regards to the design, and detail drawings, In AutoCAD format, either .dwg or.
For 16 to 22 foot aluminium boat design, similar to boston whaler designs, centre console type layout.
I am conversant with autuCAD, and have TIG welding experience, but am looking for designs with cutting schedules that could be profled by CNC machines to allow for ease of assembly. There are several designers in Australia that offer plans or plasma cut kits for small vessels. Phil Curran of CDM Marine and Gavin Mair are two of the top alloy designers here on the west coast and they have websites.
I have a 28 foot trailerable boat in alloy suitable for experienced builders but it is not a kit boat. I have the original design for the prototype available but I am reworking the underwater lines for a stern drive leg (there needs to be more displacement aft for the change of LCB), which also affects the performance potential for the boat.
The second generation hull will have a 120 hp diesel stern drive (although a four stroke outboard is possible) and will have a top speed of 20 to 22 kts and a cruise of 18 to 20. After I have built the prototype I will use the corrected sections to put together a plasma cut kit. Location: Western Australia Alloy plate for hull Yes, I can see it would be tempting to use surplus plate to build a hull, and if it is a marine grade alloy (5000 series) it may save you some dollars up front.
Overall, I think the hassle factor of building in tread plate would result in an inferior boat. These two designs are being introduced following the SC166 superyacht and the Zeus Twelve Gold Rush models, which are, to be honest, additional epitomes of luxury and great looks.
The pieces which interests us the most is the Xhibit G car – a marvelous, stunningly looking 4-wheeler to match the greatness of the Xhibitionist yacht.
The interiors is designed to host a 900-Watt 12-speaker Bang & Olufsen BeoSound audio system, carbon fiber accents on the dashboard and seats, as well as touches of white leather. Sign up for Luxatic's free newsletter and get the best news delivered straight to your inbox.


Location: Kingston, UK Just to clarify, I'm referring to the process of creating flat templates for the planks from the full scale line drawings.
Sorry if these are stupid questions but I'm new to boatbuilding and no-one seems to be able to tell me exactly how the actual build process works. Location: Oriental, NC Gus, Here is a thread on another forum of a recent lapstrake build of mine.
Once I have finished designing a hull in the software, I use the feature that creates a cutting pattern for each panel. Every time I've designed a boat in my software and used its patterns like this, the results have been practically perfect. To lap the strakes I would simply cut them an inch or two wider than the patterns illustrate, depending upon how much I want them to overlap.
I did not know if you had actually done this to completion of a clinker boat from a computer program before. If I try lapping the panels I will probably still use pre-cut plywood strakes and epoxy filler instead of bevels at the joints. Or I can put more time and effort into computer modeling and come up with precise patterns specifically for lapped strake construction. One of my concepts for the construction of a light weight lapped strake boat is to use thin plywood strakes, perhaps only 4mm or 5mm. John Welsford designs boats with stringers installed first on bulkheads and frames, then his strakes are 'cut to fit' on top of the stringers, each one beveled to the next, with the stringers visible inside the hull. I would set up the bulkheads and frames on a strongback or on the keel if the boat has one, then alternate the installation of strakes and stringers -- install a strake first, then a stringer, then another strake, then another stringer, etc.
In this type of construction the hull should be as self-fairing as in a strip planked boat. Granted this is only a concept at the moment, but I can see no reason why it won't work, although I'm sure I will discover some issues the first time I try it. If a boat has no need for frames for strength, I see no reason to ever include them in its construction.
Boats like Welsford's use few strakes and tend to show a thick lap at the turn of the bilge caused by the small radius there and thinner laps elsewhere. Improvising and improving existing means of transport has always been the priority for humans. Zolland’s design is a mix of Corvette and the boat is extremely effective and is well thought out one. Logitta Concept Car by Dr Hussien Al Jammazi Kazunori Yamauchi has challenged automakers to design supercars for GT6 video game, but it doesn’t mean other car designers can’t join the crowd to show off their concept car. This image is featured as part of the article Windy Boats and Eidsgaard Design partner on a new generation of boat interiors. The same is not just confined to the cars or bikes, but also to other means of transport like boats. We have crewed charter boats in the favourite yachting hotspots in the Mediterranean and Caribbean as well as worldwide locations. These normally cost a couple of thousand Australian dollars more than you could buy the alloy plate for, but they are often well researched and designed kits.
The current vessel has a 70 hp inboard diesel and has a top speed of arounf 15 knots with a cruise of 20 to 14 kts.
I have not built the second generation hull yet, so I have only the developed frame sections, which do not always match the shape you get in the real world. If you are in this part of Australia you can come and look at the prototype, which has been in the water for 12 months. Some of the 5000 series alloys are not as stiff as 5083, which is what is normally used for hull construction, and you would need to allow for that. The cost of the hull materials is a very small part of the overall price of any boat and any compromise you make in construction can seriously affect the value of the boat. From supercars, luxury homes, yachts and bespoke watches, to gorgeous hotels and resorts and the latest trends in high fashion.
It takes more time and effort to go for this much detail in the software because each lap must be modeled individually, but it can be done.
This has been the driving force for coming out with new ideas, be it concept cars or hybrid fuels, the motto is keep improving! Boat builders Strand-Craft, SWEDEN who have previously made some of Bo Zolland’s previous concepts a reality, are charged with constructing the Corvette inspired boat.


Looks like a very fine entry and straight run with a lot of flare in the mid sections to get enough spread for oars on gunnels ( a requirement in our class). This new concept boat by industrial designer Andrew Bedov, promises to be an eye catcher and designed with traffic stopping looks. They are normally complete with all alloy needed and can include alloy windows pre-made if required. I will do a plasma cutting schedule for the prototype but the frame sections will have a trimming allowance.
In addition, it is fitted with solar panels for additional green power, but the platform they are mounted on may also work as a concert stage or even a helipad. The Proposed power for the concept comes from a variety of engines with the maximum horsepower output of 550 hp with the estimated top speed being 70 knots. Inspired by the split rear window and svelte shape this speedboat has been created as homage, though this seems to be a cool design to zip zap zoom, it would be a tough ask for this concept to ever go into mass production. This unit has been especially designed for a luxury yacht, a […]Ronin 47 Motorcycle Project Was Based by Buell 1125 from Harley Davidson When Harley Davidson announced the elimination of Buell brand, founders of Ronin Motor Works were disappointed. My ideas come from eight years of racing and constant observation of our own two boat as well as the boats we race against.

They have always respected Buell motorcycle philosophy that is challenging […]Futuristic Citroen Taranis Two Seater Off-Road Racer Concept To all off-road racers, this futuristic Citroen Taranis should be your dream machine. Rules are almost non existant and are limited to number of oarsmen,fixed or sliding seat, or general clasification ie: work boat or livery boat. I had hoped that this thread would bring out the real designers and a discussion of general design theory. The Manta Bay Cruiser as it is called is a concept that has put to use […]Luxury Hoesch Sensamare Bathroom Design Tired of using that same bathroom everyday? Because of the shrinkage rate of alloy during welding, anything that can be bent rather than welded should be taken advantage of. To win, a boat must be able to stand up to some tough conditions yet have enough speed to achieve 6 knots+ in calm conditions.
I'm learning a computer program for boat design and have a couple of promising sketches worked up. Might put a look of dismay on the Cornish boys faces - to be beaten by a yankee 'flashboat' 'specially if they don't know you have one!
The two tiered boat design is aerodynamic, which ensures that the boat cruises through waters while it cuts through air. Try out this unique and new line of showers and bathtubs known as the "Sensamare" designed by Professor Gunther Horntrich. Tad Roberts,a designer in Washington State, a forum contributor, was kind enough to send me a set of limes showing his concept of a fast row boat, and they gave me a lot to think about.
I would appreciate a general discussion of design factors from people who are more knowledgeable than myself. A large part of his ideas will show up in my next boat if I can just get the station molds to print out on my program. Whatever she does, it's a fast boat (good crew too ) Does semi-planing happen, is it good or bad? Current plans are to put some rocker in forward to reduce bow steer and reduce wetted surface.
