I've Made a Model

Nice!

Your first model reminds me of what a streamlined gheenoe might look like. It looks good. Defintely like the updated versions much better though.

 

I see a bit of swamp boat lines in that model.
Looks kinda like an Atchafalaya crawfish pirogue.
Stitch and tape construction won't give you the most accurate work,
still, when you get to full scale construction you'll find yourself adjusting
frames and bulkheads to make the lines look better as you work.
Don't sweat the sixteenths, that's what block planes and sandpaper are for.
Wood boats are supposed to have life in their lines, not be pixel perfect.
Looking forward to seeing the final build, good work.

 

nate with a bottom as flat as that you realy don't need to build a jig. 2 of my original models were flat bottoms but I went with a small v up front for a smoother ride. I learned while making the model that the flat bottom would have simplified the process and would have cut my build time by 1/3rd. Bateau.com had a few good write-ups about the style you want to make. good luck.

 

Those are some awesome models, what program did you use?

 

trust me, at first the 1/2 inche screw ups bothered me but a little putty and shes all pretty again ;D

The biggest problem I've run into is that the masonite, the same stuff I used for modeling, doesn't act at all like wood. When I designed and even modeled my boat it was planned that the 2 bulkheads and transom would be of equal size and shape so the only variation would be the bow. Well that didn't work out at all, when I stitched it all together is had a very wavey and unnatural shape and looked really bad, so I had to remove it all and rebuild everything to the natural shape and curve of the wood. I'm really glad I did it cause it looks sweet now and gave me alot more room to build decks, plus the new shape should be a dryer ride.
I guess my point is unless your constructing a mold to lay FB in, which your not obviously, Don't count to much on finalized plans cause things will always change.

 

well don't worry to much about it, the luan can bend in many ways and is easy to work with. did you look at that web site? if you use their process but just use temp bulkheads instead of making seats you can have this boat done in just a few weeks.
I just flipped my hull a few hours ago and I can tell you that the stitch and glue meathod did produce a nice tight seam.

 

A 1/2" screw up is relative. It really depends where that screw up is located!

There is not much that a sanding block, some thickened epoxy, and some glass cloth can't correct.

I like the looks of your model, and I like that you simplified the design. I thought your original design was a bit over-built.

Are you using luan, marine ply, or what?

I flipped the Sawdust Skiff this weekend, and pretty soon will be done with Brett's construction base. I have been directed to pass it on to build another one, are you nearby? :-?

 

Same reason I designed my own skiff. After mulling over various bateau designs, I wanted soemthing that was my own. FS18 was too long, too narrow. SC16 was close, but too unstable. FS14 & 17 are cool, but too much draft. I took some of each, threw in some of Brett's ideas, and managed to mold it all into the picture I had in my head.

Once you have a model in your hands, it really fuels the build process forward. I'll be watching in the peanut gallery...

 

Contruction base? we don't need no stinkin construction base ;D ...........Although it would help.

I wouldn't bother ordering the plans cause all you will really get is sized cut outs that won't suit your build. just go at it, after a few days of work you will see the big picture. the design you made is nice and simple and you won't have any issues bending the ply to form it. I'd sooner work off your cad design, but I'd follow the bateau meathod.
(ie stitch the bow, stitch the sides to the transom, install bulkheads to get form then scribe the bottom from there.....this is extremely simple and would have saved me 10 days if I did a flat bottom)

 

During the framing of the bow deck on the Slipper,
I learned that adding a bend to the plywood adds rigidity.
After completing the build, I realized I could have used 1/4 luan
by simply adding a skin of 6 ounce glass to the underside of the deck
as well as the skin on top. Between the two layers of glass
and the curvature of the plywood, the flex inherent in the luan
is almost eliminated. And as a side benefit, the decks become self draining.

As to framing spacing, 16 inches on center port to starboard.

Nate if you look through the pictures on the sc16 you can see they used the 1/2" for the decks in a few of them. as far as bracing goes you would need very little because of how narrow the design is. Just some blocks on the sides and a bulkhead or 2 and it will be sturdy especially once its glassed.
As far as floatation foam goes, I thought the same as you, that it can be used as a structural brace but I was told otherwise by several people in the know. Basically there are several different activators for expanding foam and the floatation one will get you nice lite foam, but it will be structurally weak and easily compressed if used under a deck as bracing. If you use a denser activator then you can do that, but it won't give you the floatation you will be looking for.

your best bet right now is to go to customegheenoe.com and look at how the DIY guys made there own decks and floors. Just like here theres alot of great guys and good info. also since your great with CAD renderings and all heres a link to some old designs that a few have artist renderings and blueprints.

enjoy.

 

Well you figured out how to make a computer model where i had to go old school. Although the concept of a computer model really didn't occur to me till I saw yours. but it would have been a good tool to use especially since I had a bunch of people ask me where they could buy the plans for my boat

 

Nate if you are ever around Sebastian I would like to take you for a ride in my D15. I have built a lot of boats during my lifetime. The D15 has something about it that I can't get enough of. It seems a perfect balance between all things that I like in a boat. When fishing general species like trout, sheephead, flounder and the like I run an 8 HP 2 stroke Tohatsu. When fishing bait and spots I change over to a 3.5 four stroke Tohatsu. I have 5 registered boats between 22' and 14'. The D15 gets the call 90% of the time anymore. I also have a GV 18 cut out and ready to assemble. (shrimper)

Best regards,

Frank the d15 was what I was gonna build before I decided to design my own. do you have pictures of the build process? and is it a flat hull?
