I plan to build a fleet of long light dories, 1/8th scale, as gifts for friends kid's, out of waterproof marine plywood and titebond III, so they'll last. They'll be almost 30" long and 6" wide.
I'm planning to use twice scale thickness for sides and bottom, which, now in hand, still seems thin. I'm still working out the gunwale wood. I've seen 1/4 inch quarter round oak moulding, which would be four time scale, but add to the toys strength, yet be hard to bend the required three inches over the 2 &1/2 feet length. I could steam them - I've steam-bent wood before. I hope to find thinner oak, or use pine/basswood.
I wondered about whether I should add chine logs, until I read that Alan Speakman used S&G for his gloucester gull model. The long light dory is set up to be built without chine logs. Advice and opinions on all this I welcome.
I have Dynamite's _How to build the Gloucester Gull_, _Instant Boatbuilding with Dynamite Payson_, which has the stretched dory, and _Boat Modeling the Easy Way_.
I'm going shopping for more tools today.
