Ken,

If you try paddle-hopping you'll probably get tired before anyone sees you :D :D...

Anyway, paddle-hopping is basically a demo for something we call "hyper stability" in this boat that's just 25" wide.

There's also paddle-skiing which is as easy as regular paddling. Have a look at this movie:

You can paddle sitting and riding too.

And there's sailing, of course - sitting or standing:http://www.wavewalk.com/Sailing%20Standing.WMV

This sailing rig is still in an R&D stage and its advantage is you can sail both sitting and standing, but you can use other rigs too.

PS--Frank Hagan got me to agree to help boat builders on Messing-About to design their own versions of W boats.

Yep, and its a pretty good offer ... design advice for amature builders doesn't come around often unless you have bought plans or a kit!

I'm thinking the narrow twin hull concept could be extended to a small runabout with a 5HP outboard to get maybe 8 knots or so, which would be a safer alternative to a Jetski for younger people. And be a lot of fun for older guys like me.

Not sure how easily making the amas would be out of plywood, but there looks like there's a lot of straight sides there.

Something like this drawing Frank?

This sketch shows a kind of small W boat / personal watercraft for 1-2 persons with a telescopic steering bar that can pivot up and down, so the operator can be sitting, riding or standing anywhere along the saddle.

Unlike the W1 (the boat in the videos) which is a paddlesports boat and therefore needs to be narrow, other W boats can be made wider, for example at the top of the hulls so as to offer additional lateral stability

Also, you don't necessarily have to make the hulls narrow: The boat is a W as long as the passenger/s can sit , ride and stand comfortably with a leg in each hull and each foot resting at the bottom of its hull :)

As for plywood, I think the W concept is quite tolerant to straight lines and flat surfaces, and you can make the pointed tips from wood straps. I think Matt (JEM) could advise you on these things.

I'm working on a paddle version for stitch and glue assembly.

Ordered a plastic hull from Yoav and want to get to know the hull well and how it paddles in various conditions before working on a wooden version.

I'll probably do an open canoe version and a little longer. Got some other project to button up before going full speed ahead on the W design.
