The
BOWSPRIT mounts through the bulwark or sometimes into the hull below
the deck. Fig. 66A & B. In the latter case you must drill a hole
into the end grain of the hull. Start with a small pilot hole (about
3/32" pilot drill for a 1/4" hole, say) then complete with the
full-sized drill. A little overside will allow for adjustment of the
spar correctable with little wedges.
Having drilled the mast holes, place the LOWER MASTS,
align them, then proceed with the rigging of bobstays, bowsprit shrouds
and mast shrouds and lower stays.
