Stability in very small boats (e.g. kayaks)

[icetreader]

This is a collection of demo movies showing various aspects of stability in kayaks (http://www.wavewalk.com/FISHING_KAYAK_VIDEOS.html)
The application is in kayak fishing, touring, stand up paddling (SUP) etc.
This invention is protected by US utility patent #6871608

Sea kayaks......I wonder what affect on stability a big " noah's ark " coming up for a close look might have.....when the crew s*** themselves.....and I am only half joking.

[cthippo]

Not as bad as you might think. We bob up and down pretty well.

Oh dear...perhaps someone should have told him that putting 2 hulls side by side has been done before. The exact date and location varies from Malaysia/India to French Polynesia...all circa 2~3,000 years ago. Commonly called a 'catamaran' and seen the world over in various forms!

If this "invetion" becomes a patent, one can only laugh at the stupidity of the approval officers:o

:eek:

You have invented a catamaran? LOL!!! :D :D

I'm affraid your patent is being infringed all around the world on a daily (or hourly?) basis... By quite some time, as Ad Hoc has pointed out.

Kinda a Kool Toy.

Not reallay a Kayak and not really a Catamaran.

Lets call it a Catarack!

With something more people will understand.

Here use this instead

"Hold My Beer and Watch this!"




Those Little boats would work very well for Duck Hunting. If you want to camo up a couple, add some gun holders and Decoy storage with a Camo Fabric roof

bring them up to Maine and well field test them in the Scarborough Marsh.


I belive that they are better suited for Rowing than they are for paddling but hey, People will buy anything ( Proof: They Voted for Obama)


They need a place to mount a little 2 hp motor and maybe a Lateen Sail rig would be a nice option

I was going to give a long dissetation regarding the types and advantages of various hull configurations on stability. But Hey Ill save that for a serious discussion. Or Even Better.

If anyone needs a " Consultant, I work at reasonable rates.

That's a hellof lot of work to paddle a barge. I think a tractor innertube with a plywood bottom tied on would work better.

Duh! :rolleyes:

Here are more kayak stability videos: http://www.wavewalk.com/FISHING_KAYAK_VIDEOS.html

Ignorance is not a bliss, in reality ;)

But they aren't kayaks unless the definition of a kayak is a simple, low, paddle-propelled boat that's about 12 ft long that is made from polyethelene. They are catamarans.

[PAR]

With all that surface area, I'll bet they paddle like crap, maneuverability certainly would be sluggish, to say the least, not to mention the weight issue that must be present.

This video:

shows how it visibly slows down between strokes. Looks very draggy.

[PAR]

I didn't watch any video, I just saw the opening frame of each clip and it's pretty obvious to anyone with any level of training.

The cataract is another variation on the sit-on-top kayak theme. Many SOT kayaks have a tunnel so are effectively catamarans, that’s not new. They all share the same advantages and disadvantages to various degrees, more stability, more drag, more weight etc.

A regular kayak will slide over a floating treetrunk and paddle around anything else in the water. I don’t know why people want to paddle a boat standing up; a yuloh is easier and more effective. Almost anything that floats is better than a kayak for fishing. The rowing kayak is a joke compared to a decent rowboat. It does have more space than a kayak, but not as much as a canoe. Don't, whatever you do, try to take it down a whitewater course!

SOT kayaks are great for kids to splash around on and jump in and out of. I have to admit it has my canoes and kayaks beat when it comes to getting up on ice, but if the ice is not strong enough for that you will have to force a wider track through the ice than I need to.

[PAR]

The only time I'm in the boat forcing ice to do things, is when the chunks are too big for the glass I'm drinking out of. You guys got it rough up there.

As the scratches on the bottom of mine can attest. Maybe I should rename it the rock detector
