It employs the same basic radius chine plywood construction technique, scaled down to suit the smaller boat but takes it a step further into the plywood precut kit concept.
The backbone is also of plywood, on edge, slotted through the bulkheads as a self-jigging eggcrate arrangement to assist setting up the framework. Assembly of the hull follows the principles of model aeroplane construction, with stringers slotted into the bulkheads for attachment of the skin. The standard keel is a vertical dropkeel with a 400kg bulb on the end of the high aspect foil.
The cockpit and bridgedeck together are 3m long, giving plenty of space for working the boat while racing or socialising or sunning when cruising. The fractional and masthead spinnakers are asymmetric, set on a retractable pole on the foredeck. Included in the stock plan package are full size patterns of the backbone and various other components, plotted onto mylar film on our large format inkjet roll plotter.

Originally Posted by latestarter As expected the hull was floppy (trying to lift one end just spread the topsides at the middle) but I was surprised how stiff it was in torsion as a U-shape is not good at resisting torsion. The other advantage of putting this on now, is that you can use the frames as an accurate way of locating the height of the strake, by measuring up each side. I found that a series of laminated strips of wood were easy to apply, and looked attractive, thereby avoiding all the hassle of steam bending.
When I started this project I thought how could I avoid all the problems with bending to shape and decided to cut them from plywood and laminate. The idea is to clamp on a gunwale and adjust to the most pleasing shape, it may look a bit different as it will not be running parallel with the chines but this is true of most dinghies. Originally Posted by rwatson If you have fibreglassed all the outsides, this is a good time to put the sheer strake (around the sheer on the outside). My own preference is to add the inwales to the sheers while flat since the ply planks are floppy and the inwales stiffen them, they are much easier to do that way, although that will not work with scuppered wale's.
For your hull I suggest you install the breasthooks first which will provide additional support to the flexible sheer planks. Scuppered inwales are a little more difficult than plain ones; they help drain the inside of the boat but in a canoe their biggest advantage is added stiffness at minimum weight.
Location: Eustis, FL I've never liked the faux inwale, clamp (what Terry calls a scuppered wale) assembly. On small craft what I prefer to do is employ a inwale, directly against the planking, tied to a rub rail on the outside. Location: Tasmania,Australia Its easy to add an inwhale if the frames have been shaped to allow that, but otherwise, not. Most light boats dont need an inner and outer strake, eg many kayaks rely just on the deck for the strength. If you are worried about having to replace the outer strip after years of impact, you can have a separate non-glued extra strip around the outside, but usually its just easier to countersink any fasteners deeply, so you can plane or sand back to a firm surface prior to adding another strip to cover the damage down the track.

El_Guero Previous Member   What do you mean when you say you use SS? Having got the ends of the planks together and the the ties out, at some stage I shall countersink the holes, drill through the inner stem to link the pair of holes, then fill with epoxy and fibres to create an epoxy rivet. When making potentially dangerous or financial decisions, always employ and consult appropriate professionals. Over the years since then there have been a number of successful versions of the Yellow Cedar design in various lengths, layouts, and materials of which this cold-molded YC34 is the latest.
Designed for Barefoot Wooden Boats to compete in the 2015 750 mile-long strictly sail and oar Race to Alaska. Tilikum 32 Included in a Postscript on Barge Yachts in the Upcoming Collection of Early 20th Century English Cruising Yarns, "Under the Cabin Lamp". The upcoming collection of early 20th century cruising yarns by Alker Tripp, "Under the Cabin Lamp", will feature a Postscript on barge yachts that includes drawings of Tilikum 32 with my design comments and description: Tilikum is aimed at a certain type of performance--the ability to sail coastwise in open water, yet also creep up tiny creeks to wait out tides while resting on the mud.
Tad Roberts designed the Nomad 16 for a client seeking a boat similar to a production fibreglass design called Arima 16.
New pilot house version of Harry 2, 30' LOD sailing scow at Shanty Boat Living, March 2013 . The boat is kravellbyggget and strip-plank, first with kvistfri pine on the 22 laminated timbers, then two layers of mahogany surface above the waterline and four layers below the waterline.

Designed with maximum cockpit size, both in length and width, and intended for day fishing trips in coastal BC.
A boat that will top out at a very respectable 12 knots and be able to cruise for almost a week at 9 knots. Multi-purpose, they can be rowed, motored or sailed and are light enough for one person to lift on and off the family car or yacht. Simple stitch and glue construction, they can be built with the minimum of tools, no previous boatbuilding experience and in very little space. Either one can be the ideal quality time project for a youngster with Dad's assistance or Dad with Junior's help.
Built-in flotation compartments and a simple sail plan make them great for learning to sail, whatever your age.
The first of the two designs, the DIXI DINGHY, was commissioned as a sailing yacht tender for very simple construction in stitch and glue plywood.
As a sailing fun boat she is highly manoeuvreable and nippy with an adult or two children. After the DIXI DINGHY was featured as a kit boat in a local newspaper, THE ARGUS, I was commissioned to design a larger sister for a series feature in the same newspaper. The ARGIE 10 can be cut as a complete boat from three sheets of 6mm plywood, including bouyancy compartments fore, aft and amidships as well as rudder and daggerboard. Hardcopy plans include fully dimensioned panel cutting diagrams, hull sections, construction details, sail plan, spar details, building instructions and materials list. Electronic plans for the Argie 10, supplied by email or on disk, are in web page format and will open in the same way as a web page in Internet Explorer or other web browser, from which it can be printed on your system printer.
Finished hull weights are 22kg (48lb) for the DIXI DINGHY and 29kg (64lb) for the ARGIE 10. The small size of the vessel permits the elimination of the laminated floors needed to support the keel loads in the larger boats.
It extends from the stemhead to the transom and has large radius structural fillets to tie it into the hull skin. The hull skin is single skin plywood to the sides and bottom and the radius is done in two layers. The cabintop is designed with a multi-chine skin and is assembled over the bulkheads by the stitch and glue method for a strong and lightweight structure. Epoxy coated and painted inside and out to hull and deck, a good standard of finish is achievable with little or no fairing aside from forming fillets at internal angles.
This uses a hollow aluminum casing for the foil, constructed over tubular inner framing and fitted with the same bulb options as the lifting keel.
The inboard end is fitted on a radiused transverse track to allow the outboard end to be projected up to weather for sailing at deeper angles.
Bulkhead shapes are simple and easily set out from clear diagrams, the setting out taking about 2 to 3 hours per bulkhead. We also have an amateur projects section where you can see other projects to this and other designs. Not long ago I took it down from the rafters, dusted it off, swapped out a new motor plus upgraded the steering system. England I can see the sense in that, it would be stupid to lock in the wrong shape for the gunwales. Some of the builds I have seen, seem to have spent more on clamps for the gunwales than on plywood.
However using 4mm ply it would take a lot of time to fit and now with the cold weather a lot of waiting time between each layer. The plan is to raise the midships level by 50mm to make it feel more like sitting in the boat rather than on it, be more suitable for rowing and increase freeboard for sailing. I have left the pencil line grid on the top plank so can transfer the position to the rear half and other side of the boat to match up. Put both on dry (no glue) to check the fit and verify the clamping arrangement, also take the opportunity to verify the hull is not distorted.
It's a left over from the days of a clamp on the inside of the frame heads and not really the easiest way to do things. This still leaves a lip on the inside to prevent drainage when the hull is tipped, but you can leave them short at the ends a few inches and ditto the breast hook(s).
The designer suggests using filled epoxy on the outside to get the curve then cover with tape and epoxy.
I believe the continued appeal of the Yellow Cedar design, a classic style almost generic to the Pacific Northwest, stems from the practical arrangement, timeless good looks, and perceived efficiency of the light, full-displacement hull form. Main features of the design are trailerability behind smaller cars, seaworthiness, decent accommodation including sitting space inside, and ease of construction by amateurs.
Because there is no need to be running up to the mast, Tilikum can have a raised deck forward of the cockpit. To move the 16,000 lb (7.25 metric ton) hull smoothly through the water, Tad specified nearly 660 square feet (61 sq.
On top of this we have two layers of epoxy, so in reality we had been able to remove all the ribs. You can also open the individual graphics files (gif format) in PhotoDraw or most other graphics programs, to print them at the largest size that your printer will handle.

The addition of a layer of glass fabric to the outside will give increased resistance to knocks but will add weight and require fairing, thereby adding a fair amount to construction time and cost.
The casing is bolted through the hull bottom to an aluminum support box, which is bolted to the internal structure of the hull. They are located where they can be operated from the companionway, the bridgedeck or the weather rail. Extension and retraction of the pole can be done from either rail, with the pole retracting to whichever side is convenient at the time. The dropkeel casing forms one side of the enclosed heads compartment, which includes a bin type wet locker.
Down below it goes along with a pair of quarter berths, also more suited to the hairy chested racer and use under sail. Although not designed to their limits, she was drawn to fit within the class rules of the now defuct Australian Level Class 800 Association, a set of rules that was formulated to give boat-for-boat racing for trailer sailers. For those who would prefer to have full size patterns for the bulkheads, we can also supply them as an optional extra. At this stage about 85% of the chines were fully filleted on the outside so adjustment was not available.
The temporary frames will ensure that the strake is at the right distance from the centreline. Note the way they are shaped to accept the inwales later - this will depend on whether plain or scuppered inwales are desired.
It is a bit complicated to describe how to fit them here but you should be able to find a tutorial or blog on the net. The easiest way is to taper the outwales to a thin edge together with the rub rail if used; a half-round hardwood molding finished with a fine taper looks well with this style.
With Christmas approaching I shall not be working on the boat for the next fortnight so will be thinking which methods will be most suitable. How To Make A Cheap Boat Seat - Squidoo : Welcome to Squidoo I had the same problem when I was rebuilding my boat and so I decided to build my own boat seats that will fit my needs and won't be very expensive. Her sailing rig is designed to be folded down by the owner and kept aboard during canal cruising. This provides a wonderfully spacious interior, even though the vessel is of only moderate beam. A modern boat of traditional appearance with her lapstrake plywood topsides and wooden windshield frame. All of these parts are plywood and epoxy filleted together, making for simplified construction. I tried clamping a 25mm x 19mm batten to the outside and it fitted without the need for steaming. You can also bevel the underside on the inwale (as Terry suggests), so it'll shed water when tipped side to side. Most light boats dont need an inner and outer strake, eg many kayaks rely just on the deck for the strength .
For gravy boat owners, having axerophthol respectable potpourri of gravy boat prat accessories is very important for the tote up enjoyment of the boat.
In order to build a boat the correct design, materials and tools will need to be selected, and once . It also provides tremendous reserve buoyancy up high; she will pop right back up from a knock-down. The masts are aluminum streetlamp poles and are unstayed, although running backstays are fitted for belt-and-suspenders reliability in a rough sea or when flying staysails.
The bulb can be done in either a simple vertical sided foil section for owner casting or a torpedo shape for professional casting. A light drifter can be flown outside the shrouds and sheets to the spinnaker blocks on the quarters. The prime berth in the boat is a large transverse double under the bridgedeck, great for use on moorings or at anchor.
Whichever route you choose, we will be available to assist with advice if any problems arise.
Another way shown below is to leave the cutwater square at the top and bevel the inside ends of the outwales to blend in; getting the bevel and length both right can be tricky but not all that hard to do. I had a professional apply a layer of fiberglass to the exterior of the boat hull.  The battery I use can last several hours. If an outwale is added first the sheers are stiff enough to allow the frames to be removed while an inwale is added.
Because of the steep dory arc to the hull bottom, it handles waves pretty good, and with the low center of gravity makes it very stable.
