Default How to lift small boat from trailer?

I need to remove my boat (19 Twin Vee) from its trailer this winter to do some work on trailer. I would like to lift the boat off the trailer and store boat on blocks while I work. I own a small crane, so lifting is not a problem, but don't know how to rig for the lift.

Should I make a nylon sling with a spreader, or lift by bow and stern eyes? Or, could I just drag the boat off onto elevated blocks and then winch back on? I'm used to handling heavy stuff, but concerned about damage to the boat. Any suggestions would be appreciated.

I would suggest you call the Twin Vee factory before using the bow/transom eyes to lift with. Most boats specifically say NOT to use the eyes for lifting.

how much work do you have to do to the trailer? If not a great deal, I would highly recomend finding a marina with temporary dockage available and tie it up in the water for a day or two while you do the work, much more simple than picking the thing up.

Default Re: How to lift small boat from trailer?

I would like to work on the trailer at my leisure in my shop, which is about 2 hrs. from the coast. There's really nowhere close to my house to dock a boat overnight. Lifting is not a big deal to me, it's just the rigging issue. The easiest route would be to take the boat and trailer to a dealer and say "Fix it", but I need a wintertime project, and if I can't go boating, the next best thing is working on the boat.

I'll call Twin Vee for recommendations as suggested, and look forward to other ideas from THT'ers.

Two ways:

Fork lift or hoist that can handle the tonage.

Straps (with appropriate weight capacity) front and rear. If you are afraid of using the transom eye's then strap completely under the transom (I would use the eye's). Bow strap is alwasy a continues strap.

Lift

Remove trailer.

Place two appropiate height blocks under transom and one block uner bow

Lower

++++++++++++++++++++++
++++++++++++++++++++++


The other way I have seen it done if you don't have a hoist/fork lift is as follows:

++++++++++++++++++++++++++++++++++++++++++++++++++ +++++++++++++

Barely jack the transom of the boat off the trailer using a floor jack (don't forget to use something to protect the glass when jacking).

Put blocks or hull stands under transom (you need to put this at least 2-3 feet from the edge of the transom, this will make more sense later when you pull trailer and reposition).

Jack front of boat and put stands under bow.

Make sure boat is completely off all bunks and rollers.

Ever so slowly generally by hand pull the trailer out.

Generally you have to stop, jack and repostion the stands as you clear the various cross members of the trailer.

If you have the means to lift it with straps under the hull like a travelift in a boatyard, do so. Move the trailer & block the boat. Easy. A roller trailer is not difficult either to get a boat off of. Get the bulk of the weight, at the stern off the trailer & carefully pull the trailer fwd from under the boat. A bunk trailer is not easy. Really could use the strap method for that one.

Slings with notched 2x4" spreaders that are a few inches wider than the boat,
so it isnt compressed inwards!

with a rope tied between front and rear slings,
so the front sling doesnt slip up the bow and whoops...

I set mine in a area by the house thats deep sand, directly on the sand.

I was wondering the same thing. I've never heard of a recommendation against using the bow and transom eyes to lift a boat.

Earlier this year the dealership I bought my Grady White from assisted me in re-configuring the bunks on my trailer. They use a crane/hoist to lift the boat off the trailer. They attach the straps from the crane to the bow and transom eyes of the boat.

Probably won't be possible with a cat but on Vee bottoms it's pretty easy.

I have taken many a boat off a trailer by just using poppet stands and keel blocks. You need two short boat stands, one for each corner of the stern and numerous pieces of sturdy blocking (cinder blocks with wood caps also work well).

Get your trailer in position, put a stand under each corner of the stern and then screw up the stands so the weight just comes off the back of the trailer and then maybe 2 inches more. Keep in mind that poppet stands are not designed for holding a boats weight so you need to do everything in baby steps (in 2" increments depending on your blocking thickness). Ensure the weight of the boat is on the keel block not the stands when you are done aft.

The key to blocking is having the weight off the trailer, and on the block with just a little weight load on the stands for transverse stability.

Slowly pull out the trailer just until you are clear to block the bow. Trust me the boat will sit there just fine.

Depending on trailer configuration and height you may have to jack the bow higher once the trailer is removed by using a large hydraullic jack with a wood cap to spread the load and add some blocks under the bow. Only go 2" at a time and block as you jack. When you are done the boat will look just like they do in a marina for winter storage.

I have never done this on a bunk trailer as I owned a big roller trailer at the time but it would work in a similar fashion as long as your bunk coverings were in good shape. Our trailer had a big center roller aft that carried the bow pretty high as the boat neared coming off the trailer. It's really not as scary as it sounds.

Default Re: How to lift small boat from trailer?

Great tips from all. I think I'm going to go with a composite approach- jack/block the stern and lift the bow with crane or front-end loader. Then, I should be able to pull trailer out, block both hulls at bow, and go to work. Lifting the bow only should take a minimum of rigging. As light as this boat is (particularly in the bow), I think that the bow eye should be capable of lifting the bow. If the bow eye appears to deflect when lifting, I have thought of rigging a bridle which would pass down the center of the hulls and attach to the transom eyes, to spread the load between two points.

Trailer is a simple bunk type with guide rails on side. I'll remove guard rails first to make trailer easier to pull out from under boat.

Look forward to posting pics of a successful removal.
