Picture of Make a Hobie 18 Trampoline from Truck Tarp
Last week I re-tramped my Hobie 16 with sunbrella cloth. Here's a similar method for my Hobie 18 using heavy PVC/Polyester truck tarp material.

These old catamarans are in good shape after years in the sun, but those trampolines just go to pieces.
Here's the tramp before and after some attention from the tool-using ape.

Step 1: Set up your Workspace

It takes a few hours to do this, so you might as well be comfortable. I set up a big umbrella for shade. I set it in the centerboard slot. It wobbled around a little, so I wrapped the shaft with bicycle innertube.

Step 2: Take Pictures of How it Was

Once again, take a bunch of pictures of the original configuration.
If your boat has no tramp at all, you can refer to these.

Step 3: Remove the Old Tramp

Unlace your old tramp and slide it out of the slots in the extrusions.
To save time you could cut the lacings.
I re-used mine, but your tramp will look a whole lot better with new rope.

Step 4: Lacing Strip

Hobie calls the narrowest piece of cloth the "lacing strip".
This one is cracked and weak so I'm going to wrap it with cloth.
I keep it inside the new cloth so I can lace through the grommets.
Not having to buy and set new grommets is what makes this method so cheap and fast.

I'm fortunate to have a heavy sewing machine handy. As long as I don't hit any grommets with the needle the sewing goes well. When I'm done sewing I slide it back into the extrusion and cut slots through the grommet holes.

It's strong but it looks like crap because it's scrap cloth with crazy sewing and cut threads all over it. Don't worry about that.
As soon as the lacing is on there, the human eye will be mesmerized by the lacing and the cloth will be a blue blur. Have you ever wondered why corsets are so popular? To look at anyway?
Kinky psychology!

I like what you said about the lacing and corsets. It's very true. I always say there's nothing that looks better than a tightly lased pair of boots.

instead of using soapy water one could use silicone spray lubricant. It made my tramp a hundred times easier to install.

On the Hobie Getaway the foot strap has a half twist between each of the places where it's sewn down. The purpose is to keep the foot strap from laying flat, such that you can't get your foot under it easily. If you're making replacement tramps for other Hobie models, this would be a good feature to incorporate.
And here I was thinking I'd get to see some hybrid of a boat and a trampoline.

Never ridden a Hobie? It is that and a trapeze act as well.

Great idea! I sold my Capri 14 (like a 420) and I miss sailing... Would ya go Hobie 16 or 18?

Looks Good! "but your tramp will look a whole lot better with new _rope_." WTF! Sailor, the word is "Line"!

Thanks! My "lines" are usually not the shortest distance between two points, so I tend to call them "ropes" ;)
