Material for trailer hull supports


Recommended Posts

Both carpet and plastic coverings have trapped water between the hull and hull supports on my trailer in the past, causing damage to the paint and gelcoat.

I'm considering buying either artificial grass or cross-linked polyethylene (XLPE) foam - can anyone provide some insight as to which is superior in this case? Or should I get something else entirely?

I don't think there's anything that won't trap some water.

Previously I used carpet which held quite a lot of water.

On mine I've now used polyethylene foam, mostly because I can now get 10 inch square, 1.5 inch thick pieces of the foam, which are scrap push outs from test equipment packaging.

Ok it doesn't hold water inside itself, but there was a film of water between foam and hull this morning when I wound two pads down this morning to paint those pieces of hull. We did have 12 hours of heavy rain yesterday.

If you use a hard foam the cradle must be a perfectly  molded match the hull  or you concentrate the load on the hard spots

seams that medium density ensolite type foam about 12mm thick is a common choice

Our C&C 35's cradle pads have ribbed rubber floor runners cut to size for protection, and The Shark trailer bunks are clad with scraps of shrinkwrap film over carpet. Both boats have race prepped finishes (the 35's VC17 over InterProtect 2000e and the Shark's VC17 over VC Performance Epoxy), and neither have exhibited any damage from trapped moisture.

Some types of artificial grass are very abrasive. We used some on a Melges 24 trailer. It's windy all the time here. The boat tends to wiggle around a bit. The artificial turf rubbed through the gelcoat. No bueno.

Multiple layers of outdoor carpet seems to wick out the moisture pretty well. 
 

i am referring to the stuff that looks like a very fine  Scotch Brite Pad. 
the variety with ribs works a little better. 
 

lots of compressive wright on the carpet pile defeats it’s purpose 

 

why: Years ago, I swear that variety was sold as polypropylene carpet. I started using it because wicking clothing for hikers was made with polypropylene. 
no matter what, it dries out  WAY better than scraps cut from high pile  indoor carpet.

^^^ THIS. Spaghetti mat is the best for this purpose. You want some air circulation.

EVA and other foams can still trap water. Raised pattern is better but can still blister your hull.

It started when somebody asked this fella to identify himself.

Some, not all. Gelcoat does not like to sit in water. Plus it is not just sitting in water: the weight of the boat is pushing it against the water

smart, that will guarantee the boat is well rested!

HA!  Laughed at that one 

 

I had the spaghetti mat on my star, and where she was sitting on the pads she formed blisters from the stuff. I've had no issues after switching to the floor mat. 

 

With the weight of the boat, the spaghetti compresses and is basically flat. This allow moisture to stay inside of the little holes caused by the materials, with no way out. I;ve found that the mat actually "wicks" most of the moisture away.
