Re: [AtkinBoats] Top of Box Deadwood Line
- Due to the difficulties in the bow sections with this design I would suggest building her by the strip plank method, epoxy saturated and sheathed with fibreglass. It would take longer to build obviously, but the curve in the tunnel section and the flare in the bow ,which it seems is hard to achieve with sheet plywood would be easily achieved. The boat would be exceptionally strong, possibly(hopefully) lighter in weight and have better lasting properties than if built from plywood.1/2" strips should be ample thickness, maybe even 3/8" would be strong enough when sheathed inside and out with fibreglass. Robb White's "bastardised" RM was built this way. With his "barrel-back" stern, as good as it looks, I feel he may have actually reduced the overall sea-worthiness of the original which has considerable flare in the aft sections, but Robb being an experienced builder knew what he was doing and obviously wasn't concerned.

There's a line on the plans labeled top of box deadwood. Pretty clear
except that line extends on to the transom, representing, I assume,
the top of the tunnel chamber.
This line reresents the top of the tunnel chamber, I think, starting
out a little forward of sta. 7. It's curved and arched throughout its
I'm no expert but I believe that this shape is critical to the boat
since it should help with a better fluid flow through the tunnel and
probably provides a small amount of lift. It's also a bit hard to get
right in plywood I suspect.
Any thoughts anyone?
