    Advanced learning material on hull shape design?

    If you want to take some "professional" courses navalapp looks very promising. https://navalapp.com/ . You can sign up for just the courses that interest you, but the modelling is focussed on Rhino (which is very popular for boat design). But it's not parametric software like SW. I don't think...

    Advanced learning material on hull shape design?

    I'm no expert but I find the most insight comes from what designers write about their own designs. I think books, articles and interviews by and with people that have produced great designs are super valuable. The Bethwaite books are a good example, Bolger and the Atkins have great writing as well.

    Kick-up rudder design options

    I'm a bit late to the party, but here's my two cents. I personally don't like the "move tiller to disengage rudder" solution as it's too easy to accidentally activate while sailing, and could easily lead to breakage. Your mechanism seems pretty neat though. I think you could combine the...

    Lucky Town 7, any info or opinions?

    Although the "small big boat" factor is nice, to be honest this feels like a bit too much. On a 14 foot boat you really wouldn't want to be confined to such a small part of the boat while sailing. It just doesn't look like a boat that would sail well, and the looks don't do it for me either...

    Catamaran or monohull for efficient high speed craft

    Sounds like the Hydros hydrocontest. Some videos can be found on Youtube, unfortunately they are very highly edited and don't show how well any of the boats performed.

    Recutting skiff sail

    I used basically office supply double sided tape which is probably not as good as the "real stuff". It did not stick that well to the luff tape which was very heavy dacron, so not that smooth. It did however last a full night and being transported in the car after. The duct tape was not the...

    Recutting skiff sail

    Just thought I'd give an update on what I ended up doing. I took the luff tape/bolt rope off up to the top batten and drew a new curve on the sail, based on measurements and putting the mast and luff curve into a CAD program. Then stuck the luff tape back on with duct tape, allowing me to test...

    Amateur design insulting to pros?

    Have you looked at the Yachting Monthly Senior? Looks similar to your drawing and has been redrawn for modern construction methods.

    Recutting skiff sail

    The problem with vang is it pulls the roach over to windward, right when you actually want twist in light winds. I've put some stiffer battens in the bottom pockets, which slightly helped. I just rigged the sail on the boat and there is really no combination of settings that gives me a...

    Recutting skiff sail

    I sail a small one man trapeze skiff (Farr 3.7) and bought a second hand carbon rig for it to update it. I'm having trouble making the sail that came with it work, especially in light wind conditions. The mast is a wing-ish shape, over rotating. Below the hounds is quite stiff fore/aft, while...

    Two piece (folding) wooden spars - is it a practical idea?

    I would think some kind of scarf overlap might produce a stronger join. A metal band each end of the scarf? There are also these sweet carbon ferrules: http://duckworksbbs.com/hardware/misc/saw-frh/oar.htm http://duckworksbbs.com/hardware/misc/saw-frh/grnlnd.htm

    Homebuilt sailing dinghy for children

    A square top main will give better gust response for a given stiffness mast?

    New low-cost "hardware store" racing class; input on proposed rules

    The boats from the tv show Vikings

    First thing I noticed was the steering board on the port side. Screw up or does History Channel know something I don't?

    New low-cost "hardware store" racing class; input on proposed rules

    It makes sense to go with as square a rig as possible to get maximum area, and the traditional rigs are more suited to low cost materials.

    New low-cost "hardware store" racing class; input on proposed rules

    I'm saying a hardware store wing sail will probably be much better than a hardware store squaretop main. ... and I would totally build the proa! Hardware store crab claw sail/oceanic lateen is not a bad choice either.

    New low-cost "hardware store" racing class; input on proposed rules

    It is interesting that so much effort is being put into trying to duplicate existing solutions on the cheap. The completely out of the box lateral thinking isn't really happening yet. I built a boat for well under 600 us which has already seen 10 knots plus in moderate wind conditions...

    Optimist AutoCad

    I made a very basic model a while ago in Solidworks. I've tried to output it to dxf using Rhino3D, no idea if it works. Plans for the optimist to make your own model can be found online: http://digilander.libero.it/cvastura/Piani%20Optimist/Optimist.html...

    Wharrams to weather: How bad is it?

    I've attached a gps track from onboard a Tiki 26 with a conventional bermudan main/jib. This was tacking up quite a narrow channel in Whangarei Harbour in about 10 knots. We would basically sail right out to the edges, even hitting the sandy bottom a little at times. Try that on a keelboat...
