Re: Small boat trailer design w/light suspension, folding, good support?
There are some bunk things I do to provide boat support. I pull the rollers and put in a padded wide full length keel support, then am real careful adusting the side bunks so that they stabilize but don't significantly support the boat. Then I cinch the boat down pretty hard; becoming one with the trailer and no point loading is the goal. I also take anything out of the boat which is hard... including oarlocks, rudders, loose seats, dagger boards etc. That goes in the back of the car, truck, or on the second deck which I can rig. Seems to have worked pretty well with the ducker at about 150 lbs. After 30 plus years she leaks a little but its not because of the trailer. I think the trailer I have is rated under 1000 lbs, but I would have to go look. It is a conventional leaf spring affair, which has a break back frame, real handy for shallow launches. I bought the smallest galvanized I could find many years ago and special ordered it with an extended tongue.
If you decide to respring your trailer, lightening the springing, a custom trailer fabricator could figure out what would be needed.
