Step 16: Nail deck beams in place
Keep in mind that the top of the deck beam should sit about 3/4 inches below the top edge o the gunwales. You can move the deck beam slightly forward or backward if it sits too high or too low. The only exception are deckbeams 4 and 7, the foot brace and back brace which must be located exactly where you marked them.
At this point you will see a gap between the bottom edge of the deck beam and the side of the gunwale. Later we will close up the gap before driving dowels.
