Hi. I have purchased the plans to Bolger's Jinni, a 15' cat yawl sharpie, and am studying them after reading some books with sections on how to understand boat plans, but there's (at least) one part that I'm having trouble interpreting.
It's the little thing you see in this view of the starboard side of the forward part of the boat that looks like a tiny cowl vent (B) to the starboard side of the mast (A).
There's a better view of it in the diagram that shows how the mast can tilt aftward:
... but I'd still appreciate comments from anyone who recognizes this kind of thing.
Here's a top view of the mast step, but I don't see the little cowl-shaped thing there:
Anyone have a hint for me?
