Author Topic:   Pads for trailer frame

I picked up some small gel coat dings recently
on a really steep ramp in heavy surge when
the bow went UNDER the bow roller and hit the
frame of the trailer. We had to pick the bow
up to get it on the bow roller.

Any bright ideas on how to prevent this?

Different ramp isn't an option -- the diving
there is stupendous, just a horrid ramp.

I would back the trailer only 1/2 the way in the water and drive the boat onto trailer. I do it everytime it works great!

I had a similar problem and lost a nice chunk from the hull near the front. I purchased a flat polyurethane bunk approximately 12"x4" that fit perfectly onto a forward frame section of my trailer. I believe you can buy them in different sizes to fit your trialer. A few self tapping screws and now the bunk takes the beating, not my hull. It was a five minute fix. Where do you dive at?

I recently switched all of my keel rollers to 12" wide rollers and wow what a difference! Much easier to stay on the rollers. Also they have rubber end caps that go on the outside of the rollers to protect the boat from hitting the roller bracket. If your rollers are skinny then I would recommend the wider rollers for sure.

Chuck,

You don't describe what trailer you have or where the point of contact was but if it is the frame of the trailer, one crude but effective thing you can do is to get some lengths of black ABS or white PVC DWV pipe or some white HPDE drain pipe and slit them along their lengths.

These can then be snapped over the frame of the trailer if you get a large enough diameter. It would probably not work on a trailer frame made of box tubing because the pipe does not flex very much, but you should be able to get it over a U channel shape.

I learned that trick up in Alaska when I saw an aluminum skiff with lengths of ABS snapped over its gunwales. The skiff was used around a bunch of nice wood boats and the plastic pipe served as a crude rub rail.

Along with a whaler I have a trailer kept keelboat (sailboat). I use the swim "noodles" to pad uprights and other potential problem areas. THey are cheap, solid enough to protect the hull, cut to fit with a utility knife, and easy to attach with wire ties. I tried pipe insulation but found it was not thick enough.

It sounds to me like the wave action jammed the bow down under the bow stop roller, and because it is an all bunk trailer, the vee of the bow hit a cross frame member, where there is no center bunk protection?

Not being familiar with the bunk trailers, I now think I know why many of them have a set of keel rollers on the front cross members, which normally don't touch the hull.

I think this would solve the problem, so the boat would land on those instead of the frame. Backing in less far could also help, if that is possible.

Chuck,
I wonder if a product like Keelguard would adhere to your trailer frame? There is probably enough material in one of those kits to let you craft a very nice set of custom pads. Another thought is adapting some type of dock bumper to your trailer, perhaps gluing it on with some type of 3M adhesive. This is the sort of thing I was thinking of: http://www.westmarine.com/images/full/15302_f.jpg

I dive the Monterey area most every weekend.
I usually launch at the Monterey breakwater
where there's a nice ramp, but the diving at
Pt. Lobos State Reserve is even better, and
I can launch there about five days a month
when the tides are right, and the Lobos ramp
is best described as horrid. See
http://groups.yahoo.com/group/ba_diving/files/WebSite/launchingatptlobos.html


It's an all bunk trailer, box frame rails.
The front of the starboard sponson hit the
trailer side rail not too far aft of the
Y (Actually, it hit a u bolt that holds
running lites, but it woulda hit the frame if
there was no U-bolt).

I think it happened before the bow got to the
bowroller.

Backing in only half way isn't an option as
the steep ramp would make it difficult to haul
the boat up. I've thought about getting a
winch that's geared lower.

Rollers on the cross members sound like a
good idea.

I'm not sure the Keel Guard would work, but
dock bumper material sounds like a good idea.

The ding is on the front of one of the strakes,
not the sponson.

A roller on the front crossmember won't help,
the bunks already extend a foot or two in
front of there.
