    I just noticed all these things wrong with my first design just because someone told me one single thing. I now understand that one physical concept, [max displacement; minimum wet surface] for instance, has a huge amount to do with whether or not the thing even floats. This is why I can make a model boat that refuses to sit high enough in the water so that it doesn't take on water if hit by a wave caused by slapping the water with my hand flat. The boat looks really appealing, but it won't stay floating if it's envelope is pushed. Now I get it.

    EDIT:: I think that just making a design float is easy and that making it do anything else, is a challenge. That, is why boats are dangerous. People can't understand everything at once. We are like people with no eyes feeling along the wall

    Cool! I will have to look at them. Right now, I decided I could do a cool paint scheme.

    (It will look better when all the things like railings are installed.)

    Never got the hang of blender , maybe give it a try again . A little bit of hand drawing can be a help to some .

    I have a relative with auspergers , but he is also a passive aggresive sociopath.
    He is very smart , but has little talent.

    Well anyway, welcome, and good luck with your work .

    And welcome to Franks hall of same for bad poets .

    If we took 30,000 boat designers and assigned 3,300 people per group a task, how long would it take to build a boat? I would say that the best way would be to have a circle of judges who judge the tasks of the individuals or groups, whatever forms. Then, using separate buildings have builders make the individual sections of the ships and put the frames together like a snap together model and plank it on site for your buyer. If you have enough manpower, you can build LOTS of boats really quickly, but, you have to not use all the resources God has provided in your area.

    I'd work 16 hours a day without pay in trade for building materials and the use of some tools so I could a simple racing cruiser like a slimmed down K39 with a horizontal stabilizer on the keel or something.

    I'd want to build out of oak, but I also want to try something cheaper. Douglas fir perhaps?

    Will epoxy stick to wet wood? Maybe it would soak in less, but since it is hardened with heat, why not use epoxy to glue it together, double plank it with thin planks of different widths and epoxy and fiberglass between the inside and outside planking. Use a plank bending apparatus of some kind and account for springback for each piece compensating so everything will fit in place with little fiddling on site. Tolerances would maybe need be too tight?

    If I made a toy hull out of hard wax and placed it in a stream of warm water for a while, would it maybe erode away the wax where there was the most drag?

    EDIT:: I've always wanted a tree farm...

    This is what gave me that idea: http://www.historicships.com/TALLSHIPS/OcCre/SantisimaTrinidadSect/SantisimaTrinadadSect.htm

    I made a safety feature. I added a raised plank to the outside of the hull so that if my feet slipped they would hopefully hit the curb like structure and stay boatside of it. Then again, it could just break my toes. idk

    How big can I make this ridge? It will follow the joint of the deck and hull from stem to stern. If I make it thick and tall like a short bulwark it might displace enough water to make the side of the boat have a stiffer time rolling beneath the waves. I will show you what I mean in totality soon, I promise. =0) EDIT:: I mean it might stay more upright under sail forces. I think I just thought of a better shape though. brb.

    EDIT::: This is the beginning of what I'm talking about. The rest will have more than one purpose. This would hopefully have rounded and smoothed holes in it so that water could pass it, but it still displaces water.

    I would maybe shape the holes something like the shape of the water surface here, but angled aft at the bottom so that water will run more easily down than up through the holes. Maybe it wouldn't matter...

    HEY check out the bottom it looks like a mans head and arms stretched forward ready to take a stroke swiming beneath the boat.

    When you are on the road,do you notice the interference/moire patterns between fences/trees/buildings?

    Do you often know things,and you have no idea why you know them?

    Do you notice minute details in ordinary life and locations,and remember them even weeks later?

    I used to have all those things and more. Every day God helps me get better. I once would not walk on the reflective paint at the crosswalk if I had dirty feet because they had to be visible no matter what. idk, it seems silly and stupid now. I've had hypnocognic hallucinations when I'm dozing though. those can be scary when you are awake and can't wake up all the way because your doctor gave you a sleeping pill and a forced air facemask. .

    how about something like this, see, it is narrower down lower, but it is almost full width on top so it will slice through waves, but still not be wider than originally designed. (The midship hull and deck are the same, but the close to the front the top gets wider.)

    What I'm wanting to do is use the jutting deck on the side to displace more water so it takes more sail force to blow it over.

    George, I don't remember where I found the Etch A Sketch artwork, but it was a quick find. I might still have one stuffed in a box some place. Mine would be from the early 60's and I wish it was still in it's original box.

    OH NO I'm ruined!!

    I found a boat I don't want to modify. http://www.boatdesign.net/nyd/K800/

    EDIT:: Oopse, I lied. How would I make a gaff rig and triangular topsail... Foot loose? Could I put a big bowsprit off that chunky prow so I can move the mast forward and have a longer foot? What about a dutch sloop with a mast like pole going from the base of the mast angling upwards and just the sheet attaching the foot to anything. That way it is suspended between the two masts, but sheeted to the angled mast at the head and rigged like some freakish 200% quadrilateral genoa at the clew between the masts. On, and I forget what it's called, but put a longer piece on the bottom where the keel swings up into so that when gunkholing you have a little more keel. Maybe all the way back to the rudder?

    Like this design with a foot loose gaff boom. http://store.gartsideboats.com/collections/sailboats/products/18-ft-cutter-171

    Truthfully, I think its more closely related to BS.
