...... Reserve a slip now and that's assuming they're not already taken.

BEYC is an alternative but has no TTOL discount that I am aware of.

If you end up with no slips available, two options:

(1) There is good anchoring in a sandy spot close to shore, last line of balls from the fuel dock at Leverick. You can see the spot visually. Other places there's too much grass to get a good bite on the anchor.

(2) Finding ourselves in a similar situation last week (no slips) we took a ball at Saba Rock. $30 includes a bag of ice. This is a great spot for a nice evening breeze (no bugs) and in the spots shaded by the rock itself, its flat as a pancake.
