Not sure on the mooring - never been in April, but if its during spring break, I'd assume it would be more difficult.

For a slip, contact Nick and make a reservation - it can fill up. And yes you can leave the boat at Leverick and explore - we try not to leave it too late - usually we spend too nights and leave early morning - this way we have a whole day to explore.

When using the BBQ, just move the dinghy away from it.
