Hull Bunk Support


I've been trying to find some information about my new to me boat. Maybe some here can help.

I am lucky enough to have a place on the lake where I have the boat stored in a boat house .It comes in on a rail system that has a small cart, with a three point bunk support. One up front, in the shape of a "v", and two short bunks at the back. It seems to be ok, but I would like to make it better, for my own piece of mind.

I have a Vasserret YT, and I would like to know where the best place to support the hull is at. Keeping in mind that there isnít enough space to build the custom trailer. Any advice would be very helpful.

Also, I'm running a 150 Optimax with a CMC plate. What do you think would be my best prop?

Thanks in advance. Love the column! Lot's of good info!




Your boat cart needs 2 bunks, one on each side, placed between the center pad and the tunnel wall. Make sure they are not on the lifting strake but on either side. They will need to be about 12 feet long. We have used two 2X10's bolted together and set on end. This gives a nice 4 inch wide "pad" for hull support that runs the whole length. Mount the bunk at a slant to make the 4" pad touch the hull. (kind of tilt the top of the bunk to the center so it matches the angle of the hull bottom) 

The OptiMax will need a prop that keeps rpm in check. Try a 26 small hub Trophy or a 27 Tempest.
