Just went with SeaWorthy from CapnCrunch (Mike).
Great coverage on agreed-value policy. Many extras and very strong price.
I'm a huge fan of the no lay-up period. They give you a credit b/c most people don't boat Nov-March in the Northeast, but they don't exclude it, so you're covered in and out of the water year round. Also, higher limits for haul-out in preparation of named storm.
