Deck Work Continues on Edna

The Museum's shipwright apprentices are gaining great skills to support their boatbuilding careers. The Museum only uses traditional boatbuilding techniques on our historic fleet of vessels. 

Each deck plank is sized differently, so measurements are noted and each plank must be custom milled in our boat shop before installation.

The width of each piece of decking varies to ensure a custom fit around the new hatch

Shipwright Apprentice Joe Green explains that each silicone bronze screw used to secure the deck wood to the beams are dipped in Dolfinite bedding compound before being drilled in.

 Dolfinite bedding compound is used because it doesn't harden or cure like epoxy, which gives the deck room to expand and contract with changing weather conditions.

The seams of the deck are staggered for strength and stability, as well as to reduce the risk of rot on the beams below if a leak were to occur.

The deck around the new mast partner begins to take shape. Douglas Fir is being used for the new deck.

The Museum's skipjack Rosie Parks can be seen in the background as Joe and Jenn install the new decking.

In traditional boatbuilding, each deck plank has a beveled edge to leave enough room for a caulking iron to drive cotton into the seams. The caulk bevel is 1/3 the thickness of the decking and 1/8" into the piece. After the cotton is driven in, seam compound will be used to finish the seal.
