[Rhodes22-list] Bottom Paint - Trailer Bunks

[Chris on LBI]

I love it. I wish I had thought of that.

As you suggested, I found this related link in the archives:
http://rhodes22.org/reference-topic.html?M|reference/Maintenance%20-%20Lifting%20Boat%20off%20of%20Trailer.html

I just measured the change in elevation of the rear end of my trailer. 
Starting at horizontal, I can get about 5" of additional elevation at 
the aft end of the bunks if I lower the tongue to the ground; so a 
little more than that for the aft end of the boat. I use a 1" roller to 
apply the paint, so this will be plenty of room.

I'm not very familiar with blocking, but I'm thinking I would make 
cinder block "towers" to port and starboard and then use a 6x6 x 8' beam 
between the towers on which the hull would rest. Then I'd cut wedges to 
jamb in on each side to prevent rolling. This would be located close to 
the aft end of the bunks. I would do something similar for the blocking 
near the bow, but with the "towers" closer together so that they fit 
under and through the trailer frame. These would be about 30" aft of the 
bow. But wedges don't make sense under the bow due to the shape of the 
hull, so the forward hull would rest on the 6x6 with no wedges; maybe 
just put 6x6 blocks in on each side and fasten them into place on the 
6x6 beam. Does that sound about right?
