Moving boat back on trailer ? (perhaps)

I want to polish the hull, so I need to move my boat on it's position on the trailer.


My current tub is on bunk trailer ... how can I get at the area under the bunks to polish the hull ?
The only time it's off the bunks, is when it's in the water - not a point at which I can polish the hull.

On my previous boats I have had a roller trailer .. I would give 1 foot or so slack on winch strap, and would reverse back sharply a few feet, hit the brakes .. and boat would move back as far as strap slack.


How do I polish the hull - from a practical point, when boat is on a bunk trailer.

Thinking of one option that I need to jack up the stern - under the transom, and try and drive the trailer out underneath ? not all the way,could leave forward half the hull resting on trailer ...

If this is the way forward, anybody know of a practical way to do this.
I have a 3 ton trolley jack, but worried about damaging the hull with a point lift.
I suppose something like a forklift or engine hoist lifting hull with strap would be an option - not that I have either.

The keel is the strongest part of the boat. Block under the keel at the transom and raise it up just enough to wax what you can reach. Then jack up the bow and repeat.

The keel is a V right up to Transom ... if I try to jack up using a flat block that would be a massive load on the point of the keel ...
Perhaps I need to make a block to match the Vee ?
I could put a sand bag on the block so keel rests on sand bag, and distributes weight while jacking ?

the block of wood should be efficient enough--should give before keel does

Although the keel should be strong enough even in a point load, there is nothing wrong with making a shaped block to spread the load out a foot or so on either side. Even lay a strip of carpet on it so you don't scuff anything would not be a bad idea. Do a search on how to unload a boat off a trailer and you will find several good ideas on how to move the boat back with out much problem.
