I have a 20' Outrage which sits a keel roller trailer. Towing boat down the street at about 30 miles an hour and took my eyes off the road for a few seconds. Car ahead of me stopped and I stopped quickly. I did not lock the tires up on the truck but the trailer brakes locked up. Boat rolled forward on the trailer about four inches and bent the bracket for the bow stop roller down about 2 inches. The bracket is a big heavy duty type. The boat sits on the trailer with with two big straps from the eye hooks on the transom to the trailer and the front of the boat is attached to the winch hook and a safety chain. What can I do to prevent this from happening in the future. I am looking for some advice other than keeping my eyes on the road.

A pretty girl walking down the street in summertime clothes will do it everytime!

So, did your wife beak off at you for that bonehead move.... or did you not tell her...

( sorry Fester, I simply could not resist this one... )

( Hey did I tell my wife that I wrapped a line around my prop last night, stalled the boat just as I was coming up to our sailboat, could not stop and rammed it from behind.... oh no, that one goes to the grave with me.. no major damage done... Was a bonehead move though.. )

Sounds to me like the only support for the
boat forward is that bracket. That doesn't
sound right. I think the weight of the boat
downwards bent the bracket, not the forwards
push of the boat.

The leverage on the transom straps is such
that they are great for keeping the boat
sitting on the trailer, and passable for
keeping it from sliding (very far)
left/right, but they won't help keep it from
moving a few inches forward.

Solutions:

triangulate the bracket down to
the trailer.

bunk trailer (more friction).

Anybody got any other ideas?

Sounds like the boat's bow eye was not snugged up UNDER the bow stop roller. If it was then the winch stand is not substantial enough.

On my 25, I have a BIG HD chain which is attached to the trailer frame, and following the shape of the bow up to the boat bow eye from behind. This is for a panic stop, or rear end collision, to prevent the boat from crashing forward over the car in case the winch stand gives out.

I have sold many trailers in the years I have been in the marine business. The bow stop assembly is the weakest part of the trailer. It is designed as a stop when the boat is pulled forward not as a stop in an emergency braking situation.
The only answer is to up grade the winch stand to one from a larger trailer, overkill for normal use, yes but worth it for that panic stop.

That's the problem with attaching straps from the transom eyes to the bunks.... there is still too much slack.

Larrys recommendation about a attach point from the bow eye _toward the __rear__ of the boat_ is very good....you need to back brace to keep the load from shifting forward. Another point I'd make is rather then use those transom eye straps, is to obtain one large strap, and run it from the trailer frame, over the gunnels to the frame on the other side, touching the front of both cleats.

If you use this method, make one 180 degree twist in the strap on each side, along the hull, and the strap will not vibrate in the wind.

Chuck's comments regarding triangulating the winch stand to the trailer frame is a very good idea. Dick's comments on heavy duty winch stands is another very good idea. Another comment - make sure that your boat is snug against the bow stop because any motion of the boat before it contacts the winch stand increases that load - by up to a factor of 2 (which is applicable for a impact load). ----- Jerry/Idaho

Don, I like the 180 twist idea! I do not use the over the boat hold down method yet, but reading this thread has got me thinking about some wise "overkill" trailer modifications. The limiting chain idea should me mandatory!

If you look closely at the 4th picutre on Cetacea Page 11, you can see the chain I use to prevent forward movment of the boat in a panic or crash stop.
