I need to lift JD off the trailer onto blocks. The local DIY Marina advised they may not be able to lift a 25' vessel, they often do, but it depends on the boat.
I need to find out the ideal position of lifting straps if we do hang it off a crane.
I did construct a bow support beam to try and get the bow high enough to pull the keel out, but even with the trailer tongue as high as it would go (the aft beam of the trailer was on the ground at that point) I could still only get the front of the centerboard 2" off the trailer center board support.
I accept no liability for the advice that I'm about to give. Check with outhers first for a 2nd opinion:
For annual haulout at my DIY boat yard, I place the front lifting strap just in front of the (wing) keel. I place the rear lifting strap just in front of the internal bulkhead for the battery compartment. I don't put the lifting strap right at the bulkhead, because I like to put the rear boat stands right at the bulkhead to minimize the possibility of oil-canning or other stressing of the hull. If you're leaving your boat on the sling while you do the work, I'd put the rear one right at the bulkhead.
Wanna guess who started the thread? Scroll to the bottom & you'll see how Henk had his slung on a crane. Looks like pretty much right where the front windows are, and along the bulkhead pretty much as Rick described it. Make sure the front & rear slings are connected so they can't pop out (pretty sure that's standard practice, but doesn't hurt to check with the yard).
I'm not near the boat but, I seem to recall the word "sling" decaled on the hull under the rubrail in a couple of spots. If memory serves, those spots correspond to the reinforced area of the deck by the compression post. (Where the spotlights are) The other corresponds to the bulkhead separating the battery compartment from the aft berth. These would make sense since they would serve to stiffen the hull/deck against the compression forces of the lifting straps.
