My favorite boat is a new model tarpon 160. it is a joy in the water and a total BEAST out. 16'; 80+ lbs.
i usually transport it in the bed of my P/U with an extender. Launching is easy from a ramp,just back up and push.
Getting it back in on a ramp is another story.
I have been thinking about mounting a small winch at the cab end of the bed to help get it loaded and it would also help to secure it.
Any thoughts? One of mine was a small electric winch mounted to the bed .
