Started a post a while back on my rebuild, but have failed to keep it up. Sorry. Mostly due to not having a digital camera until just recently. But anyway. I need to get the boat off of the trailer. I have a two post lift that is capable of lifting the boat, but wasn't sure about lifting it from the bottom. I also read in another post "Another way to do it is with a gantry crane to lift the bow, or the whole boat if you so happen to have one. I use one for smaller boats, on the small aluminum boats I can sling and lift the whole boat with two chain lifts with a belly strap sling under the boat. " My boat is 17 1/2 feet long and has a 305 sitting in the back of it!!

Would the tie down eyes on the back of the boat hold the weight if I hooked to them? Or can I wrap a sling under the front and back and lift it off? I am concerned about the slings putting to much pressure on the sides of the boat and colapsing the fiberglass. It might be possible to lift it from the bottom, but not sure if the arms on the lift will go that far apart.

I know removing boats from trailers has been discussed here before and I searched for a while, so I appoligize ahead of time if I didn't look long enough to find an answer to a question that has already been asked. In my defense my connection is really slow. I am not lucky enough to have DSL.
Thanks.

I guess YES is my answer to a couple of your questions..
YES the stern eyes are strong enough..(as long as your transom is solid)

And YES, she could take the sling

Back in my old stomping grounds (Redondo Beach, Ca) They ONLY had a sling operator that hoisted and put you in the water..

I just got my 18 footer off the trailer..Though not as heavy as yours, could work the same

I felt like it would be ok to put a sling around it, but wasn't sure.I'm thinking about lifting it from the bottom. I believe I can do this easier than lifting it with slings. Thanks for your 2 cents.

Lots of guys simply lower the tounge..(raising the stern)
Then block each corner of the stern..then raise the tounge..
The stern should be lifted off the trailer..

You can jack and block inching the trailer out, but is tedious.
I didnt have the patience or help, so the pine tree worked well.

You can do it with a gantry or a post lift and two straps. I would avoid using the bow and stern eyes unless you are certain they are solid. If you have a post lift (car lift) then use the fift straps secured to the four points on the lift. If you have gantry and a single chain fall you can rig it by using two straps and a 4x4. Use the 4x4 under the keel to keep the straps pulled apart under the boat and hoist the boat using the chain fall hook. If you have two chain falls it is even easier, but you still need a way to keep the lifting straps apart under the keel. Don?t depend on friction to keep them separated, they will slip together at the worst moment. The trick is finding the balance point. You may have to position the straps toward aft so it will lift level. Sounds complicated but it is not. Much faster than blocking it up. You just have to be careful and make sure you have the capacity. I have a 12x12 gantry, really makes the job much easier.

One tool I truly love..

I wouldn't hesitate to use the lift but I would strap the arms under the boat so they couldn't slip out.... I also have strapped a 20' cuddy to a tree and pulled the trailer out from under it blocking as I go and simply winched the trailer back under it

A big thanks to all who posted about lowering the bow and blocking stern up. I decided to use this method. It was much quicker and easier than I expected. Thanks for the input.
Maybe it will go back on half as easy.LOL:)
