Is my cable lift adequate for my boat?

[bigdealsam]

I just purchased a 330 SeaRay Sundancer. My cable lift has adequate lifting force (13,000 lbs) but the bunks are only 10 ft long. Will my 33 footer sit safely on this lift? Thanks, Sam Baker

Dry weight is 10,600 according to the local SeaRay dealer. I bought her from a fellow here on Lake Norman NC so it has not been land delivered. I'm confident of the lifting capacity, I'm just concerned with a 33 ft boat sitting on 10 foot bunks. Not sure it is safe. I appreciate your opinion.

The handful of hoists on the canal behind my house have bunks at least half as long as the boats. Not sure what would be "required" but I'd want maybe 14' to 16" bunks. Theres a newer 34 SR just down from me that has 2 sets of bunks that overlap.... Some of the go fasts have bunks the full length of the hoist so they can be used from either end.

What the sea Ray Dealer said a new dry boat weighs is immaterial.
Your boat has fuel, water, ice, food, people, supplies, and Stuff!
You need the real weight.
----------------------------

As long as the center of gravity (CG) of the boat is over the bunks, it will not tip.

Where the CG of the boat is, is the big question!

Centering the Bunks on the Boat would probably be a mistake.
Centering them about 8-10 feet from the stern should be close.

But you should not listen to me as I am not there to make any judgments.
Be Careful!

10,600 dry. How much fuel and water capacity. Gas = 6 lbs/gal. Water = 8lbs/gal. 40gal water = 320lbs 150 gal fuel = 900lbs. Now add gear and the weight of people (unless you are going to offload people before you lift the boat). You're already pretty close.

Extendin' the bunks can be done....

How does your seller have it rigged? what does a dealer recommend?

there are some who believe bunks have to be under the transom to avoid the hull developing a hook.

we know from observation that few trailers and lifts are rigged that way, so it isn't true.

however the bunks should be close to the transom to support the hull and keep it from hooking. OTOH with inboards the weight is furhter forward than with outboards.

So I would be concerned about 10' of bunks under 33' feet of boat and having the boat set with the bunks more under the stern than balanced amidships. That being said, the better number is the water line length and not the overall length--you may be looking at 22' of boat on 10' bunks.

there is also a safety margin to work against screw-ups. If your set-up is too tight, and you accidentally go in too far or have the boat pushed off the bunks in a storm, lift failure, etc. you will have bigger problems. it's a factor on coastal waters; can't speak to your lake.
