I had a friend that went to a local boat yard and he rented 4 of them, they have a ton of them this time of the year just doing nothing!!

Removal from trailer
 

As for removing your Boat off the trailer in your driveway is a simple process if correct procedures are followed. I did my all by myself and a six pack.
First please buy 12 concrete blocks free from cracks etc.
Pieces of solid wood and plywood to be use as shown in the pictures.
Observe the piece of plywood on top of the blocks to evenly spread the weight across the blocks. DO NOT USE THESE BLOCKS ON ITS SIDES ONLY AS SHOWN
At all times no jacking directly to the hull (you must use piece of plywood wood in between)
Simply drop the trailer front all the way down to the driveway this will allow the stern or transom to rise to it highest point.
Simply arrange the blocks at the transom on both sides and support evenly by adjusting with wooded pieces, please observe the wood on top of the blocks and the fact its only wood to the hull at all points. If you happen to have old carpets please cut some pieces and place in between the wood and hull even better.
Now jack up the front of the trailer and this will lift the boat 75 % off the trailer.
You now need two floor or bottlenecks jacks, start by placing one in front and jack the front of the hull off the trailer, support it with solid support then slowly move the trailer out. You will need to swap the front support to work the trailer out (the reason for the two jacks or one jack and supports) out this you will figure it out once you started
It will take one person about two hours to complete.
After removing the trailer the more support you give it the better.
Please note my hull is been sanded down for a restoration project, at no point am I inside walking around on a minimal support as shown.

thats basically the way i did it. jacked the hull up and slid the trailer out from underneath, 8 inches at a time. it took a while but it was done right and sturdy. dont use stands. as mentioned before, use 8x8x16 concrete blocks. 2 by 2 by 1.
using wood blocks as shims and to protect the hull. a three point stance.
use a couple 2x6's under the chines up front to make it a bit more stable.

Here's a link to motor stands:

I've had to make some adjustments to mine since I first built it. I've lowered the top and also raised the horizontal pieces in the front and back bottom in order to make clearance for the feet of the engine hoist...

It doesn't look as nice as it first did, but it works a whole lot better...
