We have the full sailing rig w/carbon spars version. At anchor in Whangaruru at present, but headed back to the marina in Opua by the 6th. Glad to show you the boat and let you have a row or sail after that (assuming you are in the area? I've written the folks at PT WC about the situation and if I get something back about international shipping and the current order stoppage... will report back Quote Link to post Share on other sites

The Nutshells have a good deep vee. Other designs have a dead flat bottom panel right up to the bow, but with good rocker. The pram bow doesn't start until above the waterline, so only an issue if in waves, but us racked a fair bit, so not so much barge like. My understanding is that they tow better than a deflatable...

Jon 412 Posted October 2, 2020 Share Posted October 2, 2020 Been talking to Clipper we are thinking about doing something similar to the PT11 he wants the nesting and I’m keen on the fixed get the panels cut then do the rest ourselves set them up so they take a laser radial rig Quote Link to post Share on other sites

Pencil lines marked with a curvy piece of wood, jigsaw then block plane down to the lines. The trick is getting the design right so you can get the 3D shape of the boat onto 2D (flat) panels and it all fits together. But if you do the design in a CAD platform, it is also straight forward to then get them cut out. Should make tricky details easier like getting the stem just right. I really don't think it can be that hard designing a small boat, its just generally easier to buy plans because someone has already done that work. Be interesting to hear how you get on.

Jon 412 Posted October 2, 2020 Share Posted October 2, 2020 Clipper has some crowd that cut the last one he did for a bottle of rum, he said it saved heaps of sanding as panels came out spot on. Just need the cad plans now, if we did a few would really help with sourcing materials etc. Interested in how the panels are joined if the dinghy s more than a ply sheet long, if you want 6mm ply do you cut the panels from 3mm and stagger the join and glue the two to make 6mm ? or just join on a bulkhead and glass together with a beveled edge ?

Clipper 375 Posted October 2, 2020 Share Posted October 2, 2020 I agree re plans. I have bought 2 sets of plans and built 2 dinghies before. No matter what they cost, they are prob good value compared to doing it yourself. For me, there arn’t plans available for a sleek looking, nesting, sailing dinghy. I love the PT11, but that is a no go as either a kit or plans. I was. Very tempted by the woods duo, but it is just a bit basic/ugly for my tastes. Seems very close to what i was after though. https://sailingcatamarans.com/index.php/designs-2/46-beach-cats-and-dinghies/420-duo-10ft-sailrow-dinghy Quote Link to post Share on other sites
Jon 412 Posted October 2, 2020 Share Posted October 2, 2020 Maybe need to talk to Itgotknotme, if he brings in heavy stuff from the US there could be lots of room above it for some PT11 kits in the container ? We all seem to be agreed that the PT is the best looking design to date. Quote Link to post Share on other sites

Clipper 375 Posted October 2, 2020 Share Posted October 2, 2020 A lot of cnc kits use puzzle joints in thin ply Quote Link to post Share on other sites
SloopJohnB 329 Posted October 2, 2020 Share Posted October 2, 2020 Puzzle joints are the way to go. Quote Link to post Share on other sites
Black Panther 1,776 Posted October 3, 2020 Author Share Posted October 3, 2020 Yes, if you have access to that sort of thing. Quote Link to post Share on other sites
DrWatson 382 Posted October 3, 2020 Share Posted October 3, 2020 I’d like to see some testing numbers for puzzle joints vs scarfing. Scarfing is actually extremely easy using a simple home made jig for your power planer, and makes a joint that is almost perfect with respect to maintaining the plywood’s bending strength in all directions. The last dinghy I did I simple scarfed two 2.5*1.55 sheets together end to end and cut all the planks from it. Quote Link to post Share on other sites
Clipper 375 Posted October 3, 2020 Share Posted October 3, 2020 I agree scarfing is the best. But if getting panels cnc’d it wont work. unless i guess you scarf whole panels together than cut out of that. Quote Link to post Share on other sites
