I have to lift my h27 twice a year. Can anyone tell me were the best placement of the straps for the crane should be placed under the hull. Recently I had the boat lifted and the operator told me it weighed 10,000 lbs. I thought the boat was 7,500. I have a Yanmar sb8 and the mast was laid lengthwise on the boat. Does anyone know for sure?

Straps generally run equidisdant to the bow and stern, just be sure they're free of the prop. Lift operators are savvy to where to lift. Be sure to clean off under the straps, using hot water and a sponge or brush. Many a sailor let's the yard powerwash the bottom, but they can't get behind the straps. That's your job.

Weights
We've been hauling our boats by crane for many years now. I always get weights from the crane operator, usually a different crane, sometimes the same one. The weights always vary quite a bit, so I average the weights. Some manufactorers give the weight of the boat before the engine is installed (500lbs), then consider that you've added fuel, water, food, clothing.... My Watkins 27 tipped the scale at 10,000 to 10,500 even though the spec sheets say 8,500. When I'm directing the lift of boats like your 27, I usually place the leading edge of the aft strap a foot or two behind the cabin (this is far enough forward to avoid the prop), the forward strap I place just in front of the keel. -The exact locations aren't critical except for avoiding the prop shaft. -Try to avoid placing the front strap over the knotmeter impeller (better yet, remove the impeller for the haul. - Many yards have small decals "Lift Here" that can be attached to the toe rails once you find the perfect spot. Other owners will wrap white rigging tape through the toe rail holes. When you do find the exact right places, so the boat comes out of the water fairly level, mark them.

Careful When Lifting
Just wanted to caution you sailors about lifting your boat with a crane. When I first bought my L37 it was launched with a crane that lifted it with an "X" cradle. The staps were run under the boat, as usual. The problem was that the "X" was narrower than the beam of the boat. As it was lifted, the weight of the boat pulled the straps inboard on the life lines that had remained attached (with no slack). The tension caused the stanchions to "pop" at the base and I had to have them repaired at a metal shop. Fortunately, the yard took the responsibilty to pay for the fix. Just a caution!
