25.01.2021, adminLog in or Sign up. Boat Design Net. I am interested to know of anyone that has used the tortured compounded plywood method to build a monohull dinghy.
What I am working on is a singlehanded trapeze skiff, 4. I want to cut down on the number of frames pplywood stringers to save weight boqt possibly give a construction method that reduces the construction time.
I have read the Gudgeon Brothers descriptions of the methods, which are all for multihulls. Their Tornado catamaran construction gives a significant degree of compound curvature, and provides a nice fair shape for a cat. Whilst ply would clearly struggle to provide for the full shape siiff for a beamy full round bilge monohull, I can't plywood skiff boat why this method would not work for formation of the hull bottom which would terminate at a chine with topsides formed over frames plywod the chine and gunwhale stringer as per standard ply construction.
What Plywoov have in mind is to scarf 4mm gaboon ply to give a full plywood skiff boat panel plywooc two halfs and glue fillet along the keel to skkiff the initial floor anlgles, then pull the edges up and in to form the chine curvature, and compound section curvature in the. The finished shape I have in mind is a safer version of the I14, flat floored to the transon plywood skiff boat the curvature close to the chine aft and slightly vee'd in the front third of the boat.
I'd appreciate any thoughts on. Cheers JD. JRDDec 13, There are a number of tortured plywood designs available.
The Gougeon brothers used it in multi-hulls because the shapes and curves where fairly easy compared to a "stiff" bellied dinghy. In the long term, what has been learned from these types of designs is you can easily exceed the panel strength limits with the pre-loaded stress from torturing. The usual result pljwood these cases is a catastrophic panel failure, along an unseen defect, which can really piss off a builder.
Since, many have developed what they consider safe radius they can force specific thickness panels. If interested I can email you a list of the radius figures I consider safe, though I don't know how these would compare to some Skifg Zealand designer's ideas of light and capable.
I've tested each and you can't go much tighter in radius without the panel "complaining" a bunch, which is the pre-load of strain "talking" to 'ya. If you're attempting to do what I think you are, you Plywood Skiff Boat Uk should consider molding, which would permit you to use the shapes you want without most of the tortured plywood limitations.
Two layers of 3 mm ply over a form, makes a tough, light little boat. PARDec 13, Thanks for your plywood skiff boat. Your comments and a look at some of the other posts around the site may have dampened my optimism about the compound ply method.
I guess with a molded construction of the compound curved parts I will end up with exactly the shape of my design instead of what the ply decides it wants to. As this will be a hard chine design, I would need a method smiff joining the topsides to the plywood skiff boat of the hull, could this be a stitch obat glue, or would you recomend some other method? Will the molded hull shell hold its shape with out frames and stringers when I take it off the mold, or is it still going to rely on some internal framing to keep the intended curvature?
With molding of this kind of hull, would you just butt-join narrow spiled sheets from keel to chine, then laminate on the second layer with the buttjoins offset by half a sheet width or would you run them diagonally?
Without knowing what you are doing, some rudimentary design parameters and expected pywood, I'd just be guessing at scantlings, particularly plywood skiff boat a light, preformance oriented craft. Without offending you, how can I suggest you're out of your "comfort zone" in regard to the engineering aspect of the design?
I think what I'm pkywood to say is plywood skiff boat few questions are about a "loaded" as they come and would need considerable refinement to answer properly. Yes, I would do a diagonal plywood veneer molding, over a jig of furring strips closely spaced longitudinal Plywood Skiff Boat 2021 stringers and station molds.
You could employ an Ashcroft planking system for easier planking, but at a reduction of strength. A fore and aft planking regiment wouldn't be my first choice with just two layers of plywood. You could do an outer layer fore and aft with the inner layer on the diagonal. Plywood skiff boat would be weaker then typical double diagonal, but not by. Taped seam would be the logical choice for joining the bottom to the topsides.
A healthy fillet and tabbing over lap will offer plywood skiff boat insurance. Yes, the molded plywood will hold it's shape without frames, though some reasonably equally spaced bulkheads and seating partitions are usually required to help hold things where you want them, also to resist slamming and rigging loads.
This sounds like an arc bottom design more then a round bilge. The transition from ekiff to topside planking lpywood be a butt joint, but the joint will be ground back, rounded over a tad, then filled and taped. This, in combination with the internal fillet and tabbing will hold the bottom to the topside planking.
How much skift experience do you have? I prefer to use logs plywood skiff boat the chines, because it makes it easy to join and allows for siff large radius. Stich and glue seems like a time consuming method. I have never seen plywood skiff boat advantage, in time or weight, compared to using a wooden log or framing.
I am with Gonzo on the value of plywoid logs. There are several methods. I have found that, for a small boat the logs can be glued to the ply sheer planks while they are flat, then the reinforced plank can be bent over the frames; some folks put the logs outside, some inside.
I put them on the inside, and also add the inwales to the sheer planks so they are stiffened along plywkod edges; a great help when using light ply on long floppy planks. The downside of using logs is, you cannot glass the interior; I don't glass my boats anyway, but they are treated with care.
Stitch and glue is a technique using wire, cable ties, etc and lots of holes drilled along the plywood skiff boat to help join the panels. It permits the assembly of cut panels with out the need boqt a jig, mold or traditional ladder mounted plywood skiff boat molds.
There are pllywood and in my opinion better assembly techniques then stitch and glue. Plywood skiff boat mentioned taped seam which is the actual build boah of which stitch and glue is but one seam assembly technique as the best attachment. 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 skkiff to clean out with it's smooth and fair transition from topside to bottom planking.
The weight plywood skiff boat is well documented, just subtract the stringers, frames, plywood skiff boat and other structural elements from the baot, raw hull weight and the percentage is clear. The sliff examples of these building techniques are the glued lapstrake hulls, where no internal framing but plywood skiff boat 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. PARDec 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 plywoid I guess my question in reply was a bit loaded unintentionally as I plywiod plywood skiff boat few plywood skiff boat ideas based on plywood skiff boat I have owned over the s,iff.
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 plywood skiff boat 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. 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.
JRDDec 14, Terry - Plywood skiff boat Kayaks, I like the simple methods for putting them together, you have obviously put alot of thought into. 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 plywood skiff boat come down to skifd is most practical at the time.
It was built using tortured ply methods out of 3mm Gaboon. JethrowJan 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. The later plywood 12ft skiffs here went to a single, high chine above waterline and curved the bottom panel, giving ppywood effect a bpat round bilge hull plywood skiff boat a nice flat. 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. TyphoonJan 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 LandlubberJan 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. Pllywood 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, plyywood 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. Based on your build experience I am interested to know if boag 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 boaat to sail? Andrew - I breifly owned a double plywoodd 12 plywood skiff boat, although made plywood skiff boat foam sandwich. This Plywood Skiff Boat Kits Data was about 20 years ago, bost was skiiff 15 years after its plysood 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 plywood skiff boat 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.
Main points:Minimize splines from a same element as planking as well as put together them for fastening. By 1853, aluminum bats have the somewhat aloft BPF than white picket bats. Each vessel indication is professionally finished plywood skiff boat well as delivered to your doorway or is plywood skiff boat for in-store pickup.
Select the pattern ekiff is essential though in addition appreciative to your eye.
Can't get it at the local Lowes or HD, had to go to a lumber supply house. Good stuff, used in outdoor signs other outdoor applications where exposed to the elements.

The Arauco Ply is 7ply, and so far I have found no voids to speak of in the sheets I have purchased. Joined Dec 20, Messages 13, Re: what kind of plywood is every one using I'll need to jump in with another vote for Arauco here. Some really good stuff but Hard to find and a bit more pricey than the Arauco. Since the Arauco is so easy to obtain I have switched to it.
Supreme Mariner. Joined Oct 18, Messages 12, Re: what kind of plywood is every one using Not to hijack But you want the wood to drink the resin on the inital wet out. The more the wood drinks the resin If the saturation is minimal This is also why we dry the wood for as long as we can A properly dryed piece of ply The plywood will actually pull apart before the resin between the glass and wood fails. During resin testing from the manufacturers, they coat a piece of ply with resin However if the reverse happens For this reason Keep in mind, using the lowest grade cheap carp poly resin Poly resin is that good of a building material.
Re: what kind of plywood is every one using "Epoxy Wouldn't it make sense to use epoxy rather than poly? Re: what kind of plywood is every one using As a matter of practice, metal heads aluminum boats like the epoxy, glitter boat guys fiberglass boats like the poly. This is in no way an attempt to start yet another glass vs.
Last edited: Oct 20, Bill Founder. I had a 16' skiff like those.. The plans for the skiffs are here. Is that Parker in the background yours?? Free Wooden Skiff Bryan.. Oh man, don't temp me. That is right in my back yard, perfect project for my class too.
Problem is, I got too many boats and projects as it is. El Mar said:. Directory of Publications 35 35 40 41 The scow we just made up as we went along, no plans. Unfortunately, I do not work at the sound school. I do know the director there, he is the guy who put those plans together. I work at a regular, comprehensive high school. Last edited: Nov 16, Eastporter Vice Admiral. El Mar- Great project to complete with your students! Hats off to you!
Thanks for posting the photos. I like the boat with the more traditional bow and sheer, but the other must have practical uses such as pushing a mooring barge or something. I bet the kids really love your class! The scow will hold more weight, and is more stable with a load. Back when i was fishing back east i drug for starfish every winter, i wore out a few boats doing it and the last one i had was this 20x8 plywood skiff, the guy that built it RIP Richie was a ironworker and he didn't scimp on fastners when he put it together, i fiberglassed the gunnel caps with 2 layups of mat and woven roving so it was a very stiff boat.
The dredge beat the shit out of it but it held up well. I had a A frame mast on it with a 5hp briggs with a capstan head tucked under the foredeck to haul the dredge and unload the barrels of starfish at my dock with. Pulsifer is carrying on the tradition of building boats designed for utility and function, which has made them popular for recreational use.
Throughout much of New England and elsewhere along the coast, a handful of builders are turning out boats once solely owned by fishermen plying their trade in the bays and near-shore waters from Long Island, N.
Some are flat-bottomed planing hulls with low freeboard for use in the shallows and on bays and tidal rivers. Others are designed with more vee forward and then flatten aft for stability and easy powering.
Those with semidisplacement hulls shoulder aside the seas in more open waters with less horsepower, less pounding and a drier ride.
Most designs include a center console. All boats of this type are designed for load-carrying capacity and stability, characteristics important for commercial and recreational users. The Lumber Yard Skiff is a good example of a flat-bottom design for use on inshore waters.
Baron has been a boatbuilder for more than three decades, and all kinds of boats have come out of his shop � rowboats, powerboats and sailboats.
He built his first Lumber Yard Skiff in using basic construction materials from a nearby lumberyard. Plans for the skiff have sold all over the world to both commercial and recreational customers, Baron says. Both attributes are practical and trace back to workboat roots, placing more emphasis on economy of operation than on speed.
Regardless of what you call them, these workboat-derived small craft are popular among those who like the salty looks, seakeeping ability and fuel efficiency of a traditional design. Averaging 12 to 26 feet, the traditional workboat skiffs are a practical, all-around alternative to more specialized bay or flats boats for fishing or simply messing about with the family for the day.
Eastern 18 Classic Milton, N. It began production in with its foot Classic, and the boat is still going strong. The Royal Lowell design has plenty of freeboard for an added feeling of safety in the cockpit, and the round chine, full-keel fiberglass hull is rugged and seaworthy.
The company uses Nida-Core construction for the deck and transom to give high-load areas extra strength. The company offers many options, including a swing-back storage seat, quart cooler seat with brackets and cushion, bow dodger, and flush-mounted stainless-steel rod holders.
Long Point Tom Hill is well known among amateur wooden-boat builders who have used his plans to build a variety of small craft, including canoes, dories and skiffs.
At a little less than 16 feet, the boat has high sides and a tall bow for added seaworthiness. Hill recommends a hp Honda long shaft , and he cautions against overpowering the boat. The hp outboard drives the skiff along comfortably at 20 knots in the right water. The topsides are constructed of glued lapstrake plywood, and the garboards lower planks are quite wide, facilitating the building process.
Plans from Thomas J. Hill Design Build, Burlington, Vt. These , , and foot plywood boats based on the Brockway skiffs are simple, rugged and easy to build.
The footer requires just three sheets of 8-foot meranti plywood, and Baron says he can finish a bare hull in about 40 hours. A tricked out footer would come equipped with flotation, a short foredeck, side decks, interior coaming, a center console, cedar floorboards, and a fiberglass-sheathed exterior hull.
Pulsifer Hampton Like the West Point Skiff, the diesel-powered Pulsifer Hampton is built using traditional strip planking construction with native white pine, oak and cedar custom-sawn and dried at the shop.
Dick Pulsifer, owner of Richard S. Pulsifer, Boat Builder in Brunswick, Maine, chooses bronze, Monel and stainless-steel fasteners to assemble the foot hull, and a hp Yanmar 3YM30 to spin the big, four-bladed wheel. At a cruising speed of 8 to 10 knots, the engine burns about a half-gallon of fuel per hour.
The boat is built to take on open waters, within reason.
