Trampoline Material

Hi Everyone,

The trampolines you get on the multihulls (where the girls tan on ) -

What material is it made of, and how thick is it ?

Trampolines are made out of a number of different materials. One issue is how porous you want the tramp to be. Porous fabrics are comfortable, but shed water slower and can produce more windage when the yacht is heeled at large angles. Netting doesn't have these problems, but isn't as comfy on bare skin.

I used netting from Net Systems when I made the tramps for my cruising trimaran. I went with Dyneema netting with a cell size of 1" squares. Nylon netting with 2" squares is also used on cruising boats.

Sunrise Yacht Products is one of the largest manufacturers of trampolines for multihulls. They have a wide variety of materials and colors.

He he... I like your thinking, Tom

The netting sounds better and better. You don't want them to just lie (lay) there all the time. Who'll make the food ?

Does any of the SA guys know of a trawler net supplier ? I'll google and see what comes up. Thanks for the responses.

Tom, bothers me a bit the yacht heeled at large angles Mono's use netting as well now

The 25mm and 50mm large holes are quite large. I've seen some video's where the trampoline looks almost like shade netting, and you can see the sparay goes through it.

The trampoline on my friend's small trimaran is fine and smoother than shade netting, leaves no pattern as Tom said 'on the bare skin'. Can't say that it is thinner than shade netting, but it looks more like a nylon and it is finer woven.

I really like the bainbridge heavy duty mesh, it is a woven polyester mesh with a vinyl coating. The tramps are made by welding the material, not sewing where the stitching eventually fails due to UV. This is very expensive though.

http://www.sail-making.com/dbimgs/Mesh%20UK.pdf - last page.

The mesh that you saw on the windrider is probably the standard hobie tramp material, but it is probably not strong enough for bigger boats.

Thanks... yes the ultrasonic welding makes sense, it would be stronger than sewing.

Only one person can go on the windrider's tramp... it won't be strong enough for much more.

I'll find out about the netting. If it's strong, durable, cheap and can leave some interesting imprint on bare skin then it may be what to get. Maybe even catch something if you burrough into a wave

Howzit Fanie!
Get hold of Alnet or better still get hold of I&J Trawling here in CT and see what they can do for you, otherwise try Johann at Ropeworld- he'll make you custom nets out of whatever you want, any size you like.
FWIW, I know the hardcore and wannabe-hardcore cats use Vectran netting ($$$$!!!) which they roll up at the edges, then they lash the bundle to the boat. I think it looks kak, but then I'm not hardcore- cruising-cats aren't meant to be either!

I phoned Alnet, they are around the corner here in jhb from me. I think they forgot to phone back. Will remind them to phone back

It will help if one knows someone at I&J...

Could try ropeworld also... thanks.
