Composite Boatbuilding 7

Inside(Bottom) of Deck

Since outside of deck is done with glassing, now it's time to flip over the deck and do the inside of the deck.

Before we flip over the deck, sitting for the flipped deck needs to be ready.

Splash on blister was made when we were laminating the outside of deck.

To make sawhorse sitting table, we extended sawhorse legs and tried to level them with auto-level and story rod. Since it was time consuming, we brought self leveling laser level and made it at once as in video below.

Then, we needed to make sure that the deck should come off from the frames easily by removing screws, braces, frames and excess glue as in photo below.

Also some wood brace needs to be placed on the most fragile(flexible) point on the deck, in this case, it was where butt joints are.

Now, everything's done to flip over the boat, but don't forget these.

1.Mark where the splash fit on the deck

2.Mark the deck line point on the bottom of deck(Vee cut on frame is deck line) so that we could draw fair deck line out of it when flipped.

When we flipped the deck over, B/H frame also came with it and we had to take it off from the deck.

First we removed excess glue and chisel out some foam parts then did the same way as we did on dory - move the frames forward and after. But this time, frame was attached to the foam which is fragile, we did it with extra caution.

Then we did preparation for laminating starting with sanding off the excess glue and lump from the inside of the deck as in photo below.

Then we added another piece of foam(7mm thickness, may not be accurate) to the B/H and its side foams to fit the shape. Also carbon uni was placed on B/H too.

On transom, three glass plates were attached for twin rudders and outboard motor. One thing to note here is that we should try not to damage the transom glass.

Then we finished the laminating the inside of the deck.

While we were laminating the inside of the deck, we also did two B/H flange laminating at the same time.
