[Sonar] How to clean/paint the hull under the rollers

[Thomas_M_Brown at bluecrossmn.com]

For those of us with rollers on our trailers without the neat roller 
dropper that Ernie has,   I've figured out a system to get to the hull for 
surface prep/treatment in its entirety,  without having to hoist it.

As you know,   the vertical trailer stanchions that the rollers are on are 
easily moved fore and aft and in fact will fall forward or back when the 
boat is not on the trailer.       When the boat is on the trailer however, 
pull each stanchion forward by putting a line around each and pulling them 
forward with the trailer winch about 6 inches.   When two people are 
available,  lifting up on the very bow of the boat in a heaving motion 
greatly facilitates this stanchion movement.   When this is done,  the 
forward rollers in each set will be slightly free from the hull itself. 
The stability of the hull will therefore be on the other set of 
rollers...most of the weight of the boat is on the keel base.   At the 
base of each roller pair is a U-bolt that then can be loosened and the 
rollers in each set easily slid off with no danger of having the boat 
shift.       I do one set of rollers at a time  (port and stbd)  and then 
the other set before I move the stanchions aft to access the other set of 
rollers that before had been stabilizing the hull.   (I think I've got 
more rollers that most of the fleet for some reason)

To move the stanchions aft,   I put a line with a good sized block as a 
turning block attached to a short line that is attached to the motor mount 
and then again use the winch to pull the stanchions back about 6 inches 
behind .     So in essence you're doing the same thing,  except that 
you're pulling to a turning block that is aft just under the transom and 
freeing different rollers.  (I've removed my rudder to make it easier but 
this wouldn't be absolutely necessary)

While a little clunky,   this allows everywhere on the hull to be well 
exposed for sanding and for appropriate curing/drying.     Since I'm doing 
an epoxy job on Tally Ho!,   the curing time without contact with a roller 
is not really viable as free hoist time.   (it takes about 12 hours for 
the VC Performance Epoxy to cure to touch-  4 days ideally)


Hope this helps somebody.
