Hi guys I need to swap trailers on my boats and I was hoping I could do this on the lawn in the backyard. The boats are

4.6m/15.5ft old fibreglass project boat with nice galvanized tilt trailer
4.2m/14ft aluminum tinny on crappy rusted homemade trailer

Both boats very light (particularly the tinny ie under 300kg) I have a mobile engine crane/hoist and floor jacks (but no blocks/stands) so the plan is to attach the hoist with a load leveler to both the rear transom hooks/handles and lift, then simply slide the trailer out forward from under the boat and lower the rear/hoist back down leaving the boat sitting on the lawn. I figure this will work but I'm concerned with getting the front of the boat off the trailer and down onto the lawn. Will the trailer winch provide enough support to stop the nose slamming down onto the lawn from the last roller or should I put cushions or an old tyre underneath to take the fall?
I hopefully have another tyre and could possibly support the boat under the noise with the hoist still supporting the rear. I'd rather have it on the lawn though than suspended by the hoist and a couple tyres (provided it won't damage the hull).

With the old fibreglass boat/tilt trailer I was hoping to simply tilt it down and ease it onto the grass at a safe angle the trailer is a lot lower than the other one It looks like I can just dump the boat onto the grass I'm just worried about damaging the hull though?

Any advice would be appreciated!! cheers

Re: Removing boat off trailer

I just chain my aluminum to a tree by the transom hooks, slowly pull the trailer out from under it. When its time to reload, unhook trailer from truck, attatch winch strap, lift the trailer up so the bunks are below the keel and just winch it on. I leave the transom hooked to the tree so it won't take off when thebalance point brings the trailer back down to the ground

Re: Removing boat off trailer

I just did the same thing last spring.,

1. Get your boat and old trailer on a level surface and block the wheels.
2. Lower your tongue all the way to the ground - Your jack should be in travel position parallel with the ground and the tongue right on the ground.
3. Remove the winch tower from your old trailer completely.
4. Back your new trailer over the tongue of the old trailer until it starts to cradle your boat.
5. Connect the rope from the winch on your new trailer to the boat and crank it onto the new trailer.

First time I read this I thought, there's no way it can be this easy, but I did it and it is. I had a 17' springbok with 2 stroke 90hp on it. Not too heavy either.

pm me an email and I'll send you some pictures if you're interested.

Ok, I was being lazy.

Pic 1, is the boat on the old trailer, Pic 2, boat on old trailer, tongue on the ground, winch tower removed. Pic 3 is the boat cranked onto the new trailer. You can just see the old trailer behind and under the new one.

Let me know if you can see these, or do you need higher resolution?

Thanks lazybones. :lol: The pics are good. Do you happen to have one with the two trailers nose to tail? I think that's the trickiest part and I have no pics of my own. Thanks for sharing these.

Re: Removing boat off trailer

Sorry, this is all I have. You can just see the old trailer under and behind the boat in the third picture. When you look at number two, you can see the bow up in the air with nothing impeding you just backing another trailer up in there till the rollers or bunks touch it. I had rollers, I think if you had bunks they should either be wet or spray them with silicone.
