between 5% and 7% moisture content

by this time. All the paint was stripped

o , and the inside of the planking was

fully saturated with epoxy. Holes were

 lled with thickened epoxy and wood

replaced where needed.

On Timid Tuna Bandy built a new

plywood transom and sheathed it in

 berglass before the rest of the hull. “I

wanted to glass the transom  rst so the

bottom layers go over it and avoid

hydraulic pressure when you’re run-

ning,” he said.

 ose bottom layers are all 17-oz

fabric: one 0/90 and two 45/45.  e

topside sheathing is two 17-oz plies.

Bandy said he installed generous 6"

(152mm) overlaps at the chines, keel,

and tunnel edges. He’s seen enough

hydraulic delamination on boats he

has repaired to not want to take

chances with laminate edges.

Fairing only with a grinder and so

pad—his preferred method—Bandy

With both boats at a similar point,

Bandy and Hall turned to repairing

and fairing the topsides and sheathing

the hulls. Bandy said the old mahog-

any planking had been dried to

layers of  r plywood before he sold Hall

the boat, so the work on her to this point

was con ned to cutting out for the tun-

nel, framing it, and cold-molding it to

the same schedule as on Timid Tuna.

Facing page—Bandy runs beads of WEST System Six10 thickened epoxy on the

bottom frames in preparation for the  rst layer of the cold-molded okoume plywood

that would form the boat’s running surface. Above—Multiple layers of 6mm and 9mm

plywood were cold-molded into the tight radius of the tunnel Bandy designed. The

veneers were temporarily screwed to the frames while the epoxy cured.
