As requested, how to get ya boat off the trailer for whatever reason.

I have done it onto tyres on the ground with the Trailcraft, which isnt hard if you have a good winch and a roller trailer.

The following way works with bigger boats and is easy to get back on also.

It took me about 40 min this time, alone but is the second time Ive done it.

If you look closely, in all the pics the boat is actually already off the rollers and ready to move.

I happened to have 7 4wd tyres/rims that I chucked under there also in case the worst did happen like some asshole up to mischief, cant fall on concrete at least. 

Step 1/

Choose a solid spot, obviously concrete etc is best, and/or spread the load as wide as possible at the base, even concrete that is thin may not like the load over a tiny area, like stillettos on a timber floor.

Measure the height off the ground at the transom at both the chine and the keel., then also near the front.
Get an idea of where the centre of gravity is by looking at the trailer, roughly its going to be about a foot or so in front of the axle or centre of the 2 axles, it may suprise you how far back it is.

Gather enough blocks, preferable solid jarrah or similar ones.

I definitely dont recommend concrete blocks or bricks, if they shatter its all over red rover.

However if you do (and in any case) try and use soft pine as the last block against the glass, this crushes a little and spreads the load out.

Step 2/

If you dont have a good jocky wheel, put it on a skate board like in my pic.

Lower the towball as far as possible to the ground.

Step 3/

Chock the back up, making SURE that at least one of the chocks will provide lateral stability, also chock under each chine.

Its a bit of trial and error, and this is where the softwood helps as the crush spreads the load across 3 points (keel and chines)

Wind up the jocky wheel whick lowers the stern onto the blocks, after a few goes youll get it right, making CERTAIN all blocks are tight.
Pretend you are the ratbag kid of the house and boot all the chocks and shake the boat. Still on the trailer at the front it cant fall anywhere.

Step 4/

Once you are happy with that, wind the jockey wheel as high as itll go and chock under the front (just aft of a trailer cross member) then lower down to level and after a bit of trial and error youll have the boat about an inch or 2 clear of the trailer

Now if you need to, let some air out of the tyres to lower a bit more and pull the trailer forward by hand until the front block touches the next crossmember.

Use a trolley jack to take the weight (with wooden blocks) and move your front chock around the crossmember.

At this stage the boat is still over the trailer so not much to go wrong really

step 5/

Keep moving trailer forward and juggling blocks until its clear

Tomorrow in the daylight Ill take some more pics
