Trailer setup correct?

Hi all,

Collected my new boat today and have a question regarding the trailer set up.

It has rollers on the bottom and a bunk either side.

My question is: should the v of the hull be sitting on the rollers or suspended a few inches above by the bunks or should i lower the bunks so that the rollers take the weight and the bunks act as a support to either side of the v of the hull?

Hope that makes sense!

Thanks in advance

They should all work together. Where the rollers are mounted plays a part in it. Some rollers are just used to get the boat onto the trailer and then sit all alone and do nothing. Any mounted directly under the keel should be touching it and providing a small amount of support. The bunks should do most of the work.

Do make sure the transom is supported too.

Thanks Peter,

the rollers are directly under the keel but none are touching, however, the transom is supported by a roller. Will get some pictures tomorrow as it may help

I personally would lower the bunks a little (looks that an inch may do it), so that the boat sits evenly and is gently supported by the rollers and the bunks. (Bunks taking slightly more of the weight).

This should make it slightly easier to launch/recover and take some boat weight off the bunks. As has been said - ensure the last roller is within an inch or so of the transom. Otherwise the weight of the engine is able to "bend" the boat about the point of the last roller.

Thanks Ovey, thats what i thought. The roller under the transom is only 1/2 inch or so beneath. Only got the boat yesterday and want to do anything i can to help make life easier at the slipway to avoid a row with my wife!

I agree with that one! I've played with my trailer so I can happily launch/recover all on my own if needed. That way the wife (and two young boys) can go off to the marina cafe/shop/toilet or sit in the car if needed, or help if she wants to!

If it were my trailer, I would be looking hard at replacing the bunks with something far longer. Since it is a hard hull, some Trex bolted on (No need for carpet and the boat will slide on and off easier), with maybe one new stanchion forward on each side would do the trick. Just doesn't seem like the hull is well supported enough. They should extend out from under the transom too to support it. A twist would have to be put in the bunks to follow the curve of the hull.

We must be thinking of different things:


Although it would lubricate the bunks I suppose!
