| Scott.
I don't know where you live ? But you can find lot's of good plans
at the Dracut Town Libary. Try the one in your town too. Funny thing
it's not only the Large city libarys that have a lot of boat books.
A very good source is the Pebody Museum in Salem MA. or you could
look into a easy to build Phil Boldger design, He lives in Rockport
look him up and give him a call.
I'm partial to the old Francis Herrshoff designs, You can get a
listing of all his plans from the Herrshoff museum in Newport.
If your into High Tech stuff check out the Pratt Monfort designs
of Dacron skin over Kevlar Geodedic Matrix. I know it's not WOOD>
The Kittery Navel Musem would also be a good place to start as well
as a subcription to Messing around in Boats 29 Burley St Wenham
MA. Also Wooden Boat Magazine is an excellent source.
Depending on your expertise and time available you may want to scrounge
around old marinas for long abandoned boats, quite often you can
have these rellics just for the asking. I have turned down more
free boats than you can imagine.
As for building your first wooden boat, Keep it simple! I would
go for a stich and glue or a stripper design because of simplicity
and ease of construction for a beginner.
Again if it's your first boat. Don't spend too much on material.
Make it out of cheaper material like exterior ply instead of Bruynzeel
Mahogany Plywood. You can allways build a second boat later out
of good stuff if you like the design.
As for glues and resins that is pretty much a personal choice, Some
like WEST System epoxy over organic resins, I've even used good
old Elmers wood glue for stich an glue, Works fine but glass over
it!
Have Fun

| 208.2 | and ...Presto! (just add water) | HAZEL::YELINEK | WITHIN 10 | Thu Nov 17 1988 11:18 | 24 |
| I too have been lookin' at building a boat (simple dingy). A neighbor
loaned me a book called:
BUILD THE NEW INSTANT BOATS
by: Harold "Dynamite" Payson
On the cover it says: Take plywood
Cut to Shape
Smear on Glue
drive nails - stir paint
....and Presto! - You have built an instant boat
* A You-Don't-Have-to-Be-An-Expert Book *
(ISBN 0-87742-187-0)
From the books i've seen, this is about as simple as it gets. And...
as another noter put it > You don't build a boat cause you need
it....etc. You build a boat cause you want to build a boat! These
boat plans, however simple, are going to take up some space in the
cellar and take between 50-250 HRS. (depending upon complexity) to build.
The noter I mentioned above, I believe is Ron Ginger? who hangs out
in the Woodworking_and_tools file.> Check out the keywords note 7?
There are many discussions about boat building.

| Ron Ginger reads BOATS as well as WOODWORKING_AND_TOOLS! And I always
like to encourage potential new wood boatbuilders.
Both previous replys mention Bolger and Payson, and together they
are probably the best source for beginers. Bolger is the designer,
Payson builds them and writes books- The first was called just INSTANT
BOATS, the second of that series is BUILD THE NEW INSTANT BOATS.
Some of these are pretty odd- one of them is a 30' folding schooner!
(it actually folds inhalf to trailer).
Payson was supposed to be a co-speaker, along with Doug Alvord,
at our last TSCA meeting, but he doesnt like to speak in public,
so Doug came alone. TSCA (Traditional Small Craft Assoc) meets monthly
the first Tuesday of each month, in the Events room of the Peabody
Museum in Salem. The leader of the club is Bob Hicks, the publisher
of MESSING ABOUT IN BOATS. Its a low key group, mostly interested
in non-motor boats, canoes,kayaks, sailing etc. Our programs generally
alternate between builders and adventureres. The next meeting will
be Dave Getchel talking about the new Maine Island Trail Association.
Meeting is at 7:30, Tue Dec 6.

| 208.5 | Tiny Dory | TROA01::SWALKER | | Mon Nov 21 1988 23:12 | 24 |
| Thank you for the informative replies. My Interest stems from a
tiny Dory i saw (and took a picture of) in a cove off the coast
of Newfoundland. It was tied to a buoy in the middle of the bay
and was obviously used for transportation between the shore and
a fishing boat. The picture is still in negative form but my
recollection of it's size was under 6 feet.
I have a question as to the calculation of buoyancy. How do I calculate
the size of the boat based on the weight of the cargo (me), or any
other weight I might want to carry? My objective is to try and build
the smallest possible boat with an acceptable level of stability.
I was told that the calculation was as follows:
For a square boat (easy) calculate area L * W say 3'X 5' = 15
square feet * 1/12 feet (1") = 1.25 Cubic feet. Since 1 Cubic foot
foot of water displaced = around 62 pounds this means each vertical
inch of boat will carry (1.25 * 62) 77.5 pounds.
Does this calculation make sense assuming of course that the boat
does not change in angle or length in it's rise from the water?
Thanks in advance, Scott

| Thats fine Scott for a Square, However if the Square is to be paddled,
it must have a design condusive to hydrodynamic flow. If you made
a square boat and tried to paddle it you would create lift on the
forward part of the hull causing the rear to take a dive. Results
would be very wet!
The longer you make your hull, the easier it will be to paddle andd
if the width remains unchanged the wieght capacity will increase.
If the sides of your boat are vertical, Adding more wieght will
only increase draft, if you flare them outwards, Adding more wieght
will increase draft with the coefficent to the slope of the angle.
Starting to sound familler?
There is Static stability and Dynamic Stability, You need a comprimise
of both to make it work.
Read up on some of the classic boatbuilders and get some boat design
books before you start. I think you will find it will make the job
go much easier and you finished boat will perform to your purpose.
Most builder will build in Scale prior to the layup of a full hull,
Even for a small boat. This will allow you to do "Sea Trials" on
your boat before investing lot's of time and money.
Good Luck
Walt

| I get the picture, there's more to this than sink or swim...
Researchingly, Scott.
