Our
Tobago 35, with sacrificial keels, sits 6 months at a time on the keels. It tends to deform so that the floorboards rock
on the hard, and even for a few weeks after launch. I have taken, in recent years, to installing jacks under the main bulkhead and the
cockpit door bulkhead, the bows and sterns, and just taken some of the load that way. Likely helping my mind more than my
boat.
I'm sure the
boat had no extra support when stored before I owned it (former charterboat), and it shows no damage from it.
