Mooring cost was $25-35 night (don't remember, but haven't been there in about 3 years. FL Tripp is full service, with all the facilities including laundry. As for the fiberglass work, they charged a reasonable hourly rate (again don't remember) but the guy was definitely efficient and only charged for the time he was actually working on my boat (none of that coffee break charge stuff).
I've got to say we were teated very nicely at FL Tripp and the work quality was first-rate. They knew we were on vacation and put us ahead of the work queue to enable us to move on in a few days, yet the guy didn't "push" the layup schedule allowing for temperature and cure times so the structural integrity of the repair would not be a question. They even made the dock space no-charge while we were there for repairs. They also build boats there. If I ever needed major (or minor) repairs in that area and could get my boat there I'd go back again without hesitation. Unfortunately Westport is well off the beaten path, but that's one of the reasons it's still so nice.
BTW we were able to get an Enterprise rental car delivered to us (pickup/drop-off) while there so we could do some day trips while the boat was repaired.
