Just went through this myself. In Jamestown RI
$11/foot for a short haul, in slings 1hour and relaunch.
$16/foot for a haul where they cradle it for 24 hours to dry the boat long enough to get meaningful moisture meter readings. Avoids false positives.
$41.50/foot Haul, bottom pressure wash, storage outside, and relaunch in the spring.
These were quotes on a J/40.
