Why is quarter inch plywood to risky.How bout honeycomb method with quarter inch plywood sandwiched together with honeycomb structure in between. Also where can i get CAD viewer on the net.Can i submit a design to an engineer to test.Is honeycomb a proven method.I would like to make a boat about 12 to 14 feet long for fishing in lakes and able to attach at least a 9.9 outboard motor.
Is fiberglass worth doing and how expensive is this technique.I thought I would use three coats of any kind of primer with three coats of marine paint or concrete (covering) paint on the hull or bottom of the boat.I was going to use brass screws also.I thought about using ribs and incorporate them into the seats to be out of the way.Also the seats would also substitute as storage boxes.I planned on making my own set of oars with three pieces of wood each.I also thought of attaching an upright seat to the bench type wooden seat I was going to install.
Any help would be much appreciated.Thanks !!!!!!!!!!!
To start with, get plans. You can contact Small Boat Journal, Messing About in Boats or Wooden Boat for contacts for plans. We know someone who made a boat from luan, 24 feet by 4 feet, a schooner. It was a Phil Bolgers light schooner. It held a 4 man crew and won a race off Fairhaven, CT in the sharpie class. Dynamite Paysen is the name regarding stitch and glue. Use te West system over wood, not fiberglass. Most of Phil Bolgers boats can be built that way.

Why try to reinvent the wheel when there are so many PROVEN and FREE plans out there on the web?
Try http://www.svensons.com/boats for a bunch of free plans. 1/4" plywood is quite strong when properly reinforced with battens. Also, do NOT use brass screws – you want Silicon Bronze screws. Brass is brittle and not strong enough.
Check out http://www.glen-l.com and http://www.clarkcraft.com for more plans, and for supplies to build your boat. Epoxy resins are much better than polyester as they have better bonding abilities. Those last two sites have lots of good info on various types of plywood construction including stich and glue.
Most designs do not require the added weight, work and cost of fiberglassing. Alternately for waterproofing, you can coat it in epoxy resin (without cloth) – it will be faster, thicker and cheaper than several coats of paint – you can still add a coat of paint on top of you wish.

hi im a old boat builder,22 years see i said old..ive built hundreds of small skiffs in my day..if you want cheap and long lasting here you go.14 ft you need 6 sheets of 1/4 ac fir for sides and seats, 4 sheets 3/8 ac fir for the bottom,1 sheet of 3/4 ac for transom cut transom to your liking wide as you want to ,esceptions are for work boats most of my low powered boats are about 3 to 1 ltry for a boat 4 ft on bottom and you can save even more in supplies,,make your transom 4 ft wide at bottom 5 1/2 ft at top,lay 2 sheets of 3/8 on floor nail a temp splice to hold together,nail transon to back of ply wood in stand up ,,brace it at around 12 % leaning back, cut boat sides same as transom in back STOP rememer sides have a tilt and a bow from1/3 forward of the transom STOP.. DONT FOGET TO LEAVE EXTRA ON SIDES BUY TRANSON !REMEMBER THE TILT ?take along thin boardan go from transom and bund to shape you like temp nail in place mark out line..theres your bottom if your happy with you work good if not eye ball it again move the long board till you like what you see ok make a board to go across the dead center of the boat this board makes the flare at the top when you add the sides.ok now put the sides on ground and fashen them with a 6 inch 1/4 plate on the inside now you have one long 1/4 plw wood16 ft take scrap piece 2/4 cut to the hight you want the bow to be nail the two long sides and you will see a boat no your not done but i think my 12 year old son could figure the rest out
