cruise is in good form, 12. If a pattern functions effectively idealisation drawings have been plywood skiff boat design as well as a pattern is done accessible to vessel builders.
He demonstrated the bifoiler (two foils solely) after being educated it was improbable to balance??- dual foils usually thought - was receptive to cruise bat parading up as well as down in opening of a sailors upon a Seaforth Plywood skiff boat design Bar (I hold that's a story).
It's lighter and stronger then a solid wood log and it's not prone to hold debris, dirt or moisture such as can be on top of a log and it's a lot easier to clean out with it's smooth and fair transition from topside to bottom planking. The weight savings is well documented, just subtract the stringers, frames, floors and other structural elements from the assembled, raw hull weight and the percentage is clear. The best examples of these building techniques are the glued lapstrake hulls, where no internal framing but for a few bulkheads can be seen.
I've long but stopped using "stitches" to hold seams together, though occasionally a well placed stitch can solve a few problems. PAR , Dec 14, I think what I'm trying to say is your few questions are about a "loaded" as they come and would need considerable refinement to answer properly" Not offended at all - I guess my question in reply was a bit loaded unintentionally as I have a few pre-conceived ideas based on boats I have owned over the years.
Your answer provoked an interesting new line of thinking I had not given much consideration to previously. I have sailed boats such as Farr 3. But have not built one from scratch My initial tendency was to use a composite foam sandwich construction which I am familiar with for small scale work and is normal practice for small race boats these days.
But have been getting more interested in the way that some more traditional methods could be applied to a modern hull shape and also keep the cost down. Most likely I would ended up with a ply on stringer frame but suggestions so far do pose some interesting alternatives. I will try and get the my latest shape off paper onto cad so I can post it in the next few days.
JRD , Dec 14, Terry - Nice Kayaks, I like the simple methods for putting them together, you have obviously put alot of thought into this. I'll have to get off my computer back to the sketch book to figure through a few of these ideas. Im thinking the chine log vs glue fillet will come down to what is most practical at the time. It was built using tortured ply methods out of 3mm Gaboon. Jethrow , Jan 8, If it's going to be single handed, trapeze and 55kgs, just build a single or double chined hull.
It'll be up and planing very early anyway. The later plywood 12ft skiffs here went to a single, high chine above waterline and curved the bottom panel, giving in effect a reasonably round bilge hull with a nice flat bottom. The chines also started about halfway back along the gunwhale from the bow, most of one side of the boat was one joined piece of ply.
Regards, Andrew. Typhoon , Jan 9, You can also make constant camber sheets with foam in between for stiffness, they will then be used to construct the shape that has been predetermined Landlubber , Jan 9, Thanks so much for all your suggestions.
Jethrow - I have taken a careful look at your construction photos Very nice looking boat, I hope its getting plenty of use this summer. What you have built is very similar to what I had in mind when originally posting this thread.
I have attached the current itteration of my design, its not quite there yet but close to what I am trying to achieve. I'm not fixed on the concave flair evident in the topsides. I hope to find time to draft a hull shape that may be a little more suitable for folding up as you have done.
Based on your build experience I am interested to know if you think this could be done with the hull I have posted with the exta beam and curvature closer to the chines. What was the final weight ready to sail? Andrew - I breifly owned a double chine 12 footer, although made of foam sandwich.
This was about 20 years ago, which was about 15 years after its used by date. This was lighter, faster and required 2 hours of repairs for every hour of sailing. The ply 12s were a wee bit before my time. Were they a ply over stringer frame, or tortured ply similar to Jethrow's International Canoe? Terry - I dont think the ply over ribs fits with what Im trying to do, although I think it will work well on your new canoe. I look forward to seeing one under construction.
This is the alternative I'm looking at, but would be likely be formed over stations before laminating the glass to the foam. Cheers, Jeff. Jan The steering console is not recommended.

The seam probably won't need any filling. One strip of fiberglass is enough to join plywood up to 6. This boat would be made of 6. First cut the sides. The crucial measurements for the front part of one side are given here.
The upper, visible edge of the boat side comes from the factory edge of the ply, so at least that edge will be straight and clean. There are other "standard" plywood sizes, too, but this is probably the most common standard. Or anywhere between for a look "between". Measurements for the rear part of the sides. Measurements for the transom are not needed, the left over part from between the side parts makes the transom "as is" the bright yellow piece.
Then mark points E, F and G on the edge of the ply. The width of the hull will be set at these points using three lengths of board. The board between points Diy Plywood Mini Boat Designs E should be mm 33" long, ends cut at 68 degrees for the "modern" version, 71 degrees for the "traditional". The board between points F should be mm 46" long, ends cut at 66 degrees both versions.
The board between points G should be mm 43" long, ends cut at 64 degrees both versions. If You don't feel comfortable with cutting the angles, forget about them. Just see that the distance between the sides of the boat at E, F and G are correct.
From here on, just follow the building instructions on the "Portuquese Style Dinghy" pages. Except that the bow stem angle in this case is 67 degrees for the "modern" version, 57 degrees for the "traditional", so some planing is required. A lenghtwise seat would be quite proper, but traditional ones may also be used. I can think of two sensible traditional seat arrangements. A rear and front seat could be added, for three people on board.
But I won't, because the temptation to seat two people in a configuration only suitable for one or three would be too big. With two on board she would drag her transom, would be hard to row, and You'd think it's the boat's fault. Second, two seats, optimized for two people. This configuration just about works for a single person on the front seat, being slightly bow-heavy, however.
