Mark is on the right track. It is a Venture bunk model and has never had the boat on it and I will pulling it for the first time next month. I really just need the basics and I will refine it down the road as necessary.
I would like to know how high off the frame the winch is so I have some basic alignment from the start. I am assuming that the winch would be roughly in line with the bow eye as the boat comes forward. I also posed an early question never answered about the width of the side guides and perhaps how high they are vertically related to the bunk supports.
These items are all easily moveable on the trailer but I would like to avoid too much wrenching at the ramp next month.
Thanks to anyone with a few minutes and a measuring tape,
Greg
