No, I'm not making a snorkel. As it is, the base of the sail is already getting in the way of where these masts would go down. So that will take some work on the builder's part to make clearance for them, unless they just cut them off so they barely sit in the top. That's up to them.
But there has to be some substance to the front and back of the sail in order to affix it to the hull. There's about 3/8 of an inch from the front, that is solid all the way from the top to the bottom of the sail. Then about 1/2 inch at the back the same way. WHere it touches the hull, this gives places for attachment screws to connect into.
Kevin, what comes up in the third row back on the port side behind the antenna mast? There's one more mast opening there that I have not found any pictures of it extended.
