15. Roll Over System

I had to give the bottom of the boat a new coat of paint.
Interestingly,  I had some small pitting in the paint show up after the winter season of  2014.  The pitting occurred under one of the carpeted trailer bunks.  The boat is stored in the garage and I believe what happened is that the snow melt from the car that is parked along side of the boat had a lot of road salt in it.  Even though I squeegee the melted slop out of the garage, I think that there was still enough salty moisture to wick up into the carpeted trailer bunk and ultimately pit the paint a bit.  So in the Spring, I rolled her over, sanded, and applied a few new coats of paint.  The tech at Interlux suggested that the first new coat of paint be what he called a "stripe" coat.  Essentially a coat that is thinned out more than usual.  I applied this stripe coat then 2 more regular coats using the roll and tip method sanding with 400 grit between coats.   

So,,,,,Here is the boat rolled over.  It is sitting on sawhorses that break down for storage.  The top surface of the saw horses are covered with carpeting. 
Note the 2 yellow straps.  These are heavy duty tie down straps that I have sewn together to form a continuous loop.  They are threaded into a ball bearing roller block assembly as pictured below.  While the boat was sitting on the trailer, the straps were positioned around the boat and then the boat was lifted off the trailer using the block and tackle system that is attached to each of the 2 roller assemblies.  The trailer was rolled out of the garage.  Then the boat was easily rolled over while hanging in the 2 straps.  Once upside down, the boat was lowered onto the saw horses.



Here is a close up of one of the roller assemblies.



Here is another view of one of the roller assemblies mounted to the 2X6 attached to the rafters in the garage . 
Note the block and tackle system.  The line that run from the block and tackle terminates at a cleat mounted to the rafter as well.  When the boat is raised or lowered,  each roller assembly is moved independently a small amount at a time with the line cleated after each movement.  It is a little time consuming, but I can do it by myself in probably 15 minutes.

A view of one of the roller assemblies disassembled. It is made up from 2 wheel barrow wheel bearings, 2 washers, a piece of tubing, a 5/8" bolt and nut, and brackets made from 1" wide strapping bent as shown.

Another view of the roller assembly. 
Notice the Hitch Pin that is going into the nut on the back side of the roller.  I pull this pin to un thread the nut and pull the bolt in order to install the continuous loop of yellow strapping.  Then I re-install the bolt, nut, and hitch pin.



This is one of the cleats where the line from the block and tackle terminates.  I use these to secure the line when I raise and lower the boat a little at a time.
