...and now for something completely differen't (new Kayak)

[Fiskadoro]

So since I've moved out of the math stage to the make a lot of noise stage I thought I'd share this....

Does this look like a Kayak to you?

Now it's starting to look like something... sort of...

That actually looks kinda like a kayak.

A few for scale...

So this is going to be my motorized (gas) off shore fishing kayak (Sit on top) that I'll be able to launch in the surf, paddle or run on power and fish offshore for local tuna, paddy yellows, mahi etc....

Stats length 21 feet beam 29 inches.

The idea is to combine my older passion for offshore fishing, with my new interest in Kayaking. My design and manufacture process, one of a kind, nothing ever built like it, don't try this at home...etc...

I'm sure you realize once you motorize it, you'll have to register it (CF#'s) and once you get CF#'s that makes it a boat, and that will greatly diminish the number of beaches from which you can surf launch.

Let's see, I can think of one.

Sleek design, anyway. Have fun.

You can't win them all... LOL

So which beach are you thinking about?

This is not meant to be a general use kayak.

I'm going to be powering it with a 2hp Honda 4 stroke. Sailboats that have used those motors as auxiliary power have reported mileage up to 40 miles to the gallon.

I'm planing on building a five gallon internal tank in it, since my hull is a lot lighter then a sailboat (by thousands of pounds) with far less drag and I should have much more range and speed then I can utilize.

With range and speed you don't have to launch right on a location to fish it. I'll primarily be launching it out of harbors, or perhaps at off the beach if I take it to Mexico.

The kayak is a hybrid of kayak, sailboat, and displacement powerboat design. It's going to blur the lines between what is a power boat and a kayak.

I'm designing it so it can launch and land in the surf, but it's not only what it's made for. I have plenty of kayaks I can fish out of the surf this one is designed for range, and sea keeping abilities so I can take it further offshore then a more standard kayak.

Great thought, great craftmanship. Looks beautiful...

Now to the nitty gritty...you plan on installing a bilge pump, preferrably an auto (float) bilge? Would need an extra battery for that, esp in case of leakage.

If you don't, and do develop a leak, you are officially FUBAR.

The nittier of the gritty...2 words...

Hull displacement...:eek:

Make sure you put some whale tails (cavitation plates) on the outboard to help you plane better...just my 2 centavos...also check your rocker...and don't go out on 'swell' days...and make sure you have smooth, continuous beads on the welding points...

And as Zed pointed out, you are officially a motor boat under power.
Have all the necessary equipment, make sure you rinse thoroughly after every use, and only go out on days where LJ to the 9 mile bank is glassy...and make sure you use plenty of sunscreen under your chin, that aluminum (or SS) will cause a nasty glare...

I actually have about ten times the experience Offshore that I do kayaking, and have designed and built other small power boats for offshore. I actually have kind of have a reputation as a small Aluminum boat Guru. Do to several of the projects I have done in the past. I get calls to work on boats all the time but I usually do not have the time to do it.

Here's a few recent projects a repair and a T top mini tower and bait tank leaning post set up.

Probably many of seen these Photo's before.

Here's one of my favorites: a modified Western 14ft skiff from a few years back that Iredesigned for offshore use.

That's all the same boat. People thought I was crazy when I started it but it turned out OK.

It was initially just built as a prototype, but it's worked so well I kept it. I've maybe got a thousand hours on the boat since I rebuilt it and have taken that skiff all over out to about forty miles with no problems.

I've targeted a lot of Tuna and T's with it..

I'm essentially designing the new power Kayak to target the same fish without the TSharks.... :biggrinjester:

That thing looks cool but I bet it is not very buoyant. It might not be much fun to be on after taking a couple waves in the chest during the launch. Have you designed in some floatation?

I should of seen this coming.

You have to understand what your looking at.

Right now your just looking is the hull, just the sides and bottom. The top decks and the cockpit have not been installed. This is not going to be a canoe or an open boat.

Like any sit in top the hull will be sealed with decks for an aft with a self bailing cockpit in the center and access into the hull it will be thorough water tight hatches. I figure when it's done the weight will be around a hundred pounds but the displacement capacity or flotation will be almost eight hundred pounds.

The closest hulls to it design wise are triple kayakshttp://www.solarnavigator.net/images/kayak_triple_seat_muddy_water.jpg

It has to be oversized so that it can handle the power without driving under in seas.

A good size triple with a hull the size of mine could support three paddlers all over 200 pounds plus their gear.

On the safety side the hull will have three sealed water tight compartments separated by bulkheads and several cubic feet of foam at each end.

One = La Jolla Shores
I can't think of any other beaches where you can launch a boat (Baja excluded).
...and make sure you use plenty of sunscreen under your chin, that aluminum (or SS) will cause a nasty glare...Heheh. Funny.

I'm not worried about your craftsmanship or materials, there's plenty of iron hulls with poured concrete out there. Go get 'em.

Maybe you should get your hands on a longtail motor.

Nice work! I need something like that T-top on my skiff!

[KennyHill]

That thing is crazy! I cant wait to see it when its finished and some on the water shots. Keep us updated on it... Goodluck:cheers1:

[WCW Moderator]

Jim, That is looking good! I picked up the foot pegs and rails yesterday if you still want em, give me a call.

and I think it needs one of these shiny doo-dads

Looks cool Jim, I remember when you built that skiff a few years back. One of the coolest projects ever IMO. What's the weight estimation on the aluma-yak?

[dos ballenas]

Very nice skiffs!!!

Where does he get such wonderful toys?

[punchjamesarnol]

Hey Jim, Looks to me like you do fine quality work. Keep us updated with the project! I'd like to see it in progress. Double thumbs up!

[steamroll]

You'll shoot your eye out

[Mr Mugu]

One = La Jolla Shores

Escondido/BKR in Malibu still gets a bit of use as a boat launch.

We've also got Carpinteria Reef/Ash Street launch up here which is exactly the same as La Jolla...drive on the sand and launch motor boats and kayaks.

Even the waves are like La Jolla(The City used to call it the safest beach in CA.)

Too Funny.... :D :D :D :D

Jim,

You will be disappointed with the honda 2hp. I have one and it's a pain to transport/deal with. It leaks almost every time I need to lay it down. And it's air-cooled--much louder than you would expect for a 4-stroker.

My recommendation is go with a Nissan/Tohatsu 3.5hp 2-stroke. About 22lbs, and very reliable. I have one too--and I much prefer it over the Honda. It's much easier to store (no oil to spill) and much more reliable (surprisingly).

They do sip gas, both of them.

I've always liked bars.... Thanks for that info. I'm still working out the cockpit geometry and need to figure out the rudder before I jump on the footpegs but likely that is the route I will go. I'll know by tomorrow.

Andy wait until you see the scupper system I've worked out, I think your going to love it. :D

[THE DARKHORSE]

What's your E.T.A. on the finished product? Maybe we could buddy boat for some local tuna...my legs never run out of gas :D.

[Law Hand]

VERY NICE WORK!:you_rock:

I want to be done before the tuna get on the 302 bank, can you do thirty miles? :sifone:

[Dan]

killer project. do you plan on having an outrigger on that? your shop looks so cool.

[Billy V]

Jim,

I have the 6 HP Nissan/Tohatsu for my porta-bote, it is a very economical motor that will give you some reserve power if needed.

The weight is 55 lbs and it can be transported on its side without leaking.

I'm sure you would have the fastest kayak in Cali.

I was thinking more along the lines of one of these:

JetCat P-160 turbine complete with starter includes:

Jet-tronic ECU (fuel control electronics), GSU (Display and Programmer), LED I/O board, Miniature fuel pump, Electronic starting gas valve, Electronic Fuel valve, Fuel tubing, tubing connector set, filters, and cable set, 6 cell 1250mA battery pack , Starting gas tank, Turbine mounting clamp, RamTec compatible, Detailed instruction manual, Thrust: 34 lbs @ 128,000 RPM

Weight: 3.34 LB
Diameter: 4.4 inches
RPM Range: 32,000 - 128,000 RPM

Hey you can't beat the weight to thrust ratio!!!

This guy definitely has the right idea:

[payaso del mar]

also own a 2hp honda for sevl years and concur with Joe somewhat. the thing is noisy as hell....i worry about waking up the cruisers sleeping on sailboats in the marina when i come in at night! it's louder just off idle than my 8hp Rude is at 3/4 throttle. i can only imagine what it would sound like with that nice aluminum resonance chamber you're building.... beautiful fabrication work, BTW!

the leakage of oil can be avoided by being careful to never set it down on wrong side, as with most 4 stroke motors. but you'll never get the gas cap & vent opening sealed well enough to keep gas in (MR Honda lies when he says you can), so plan on draining it when you shut it down, or monitor your fuel so you nearly run it dry when you come in.

aside from the noise, great motor. one guy on Trailer Sailors shoved his MacGregor 26 sailboat at 5 knots with one; it will get maybe 7 (statute) mph on the 12' portabote per my GPS. it might be a little underpowered to battle wind on the open ocean. fact that it's 100% air cooled (unlike the "air cooled" outboards of yore, which often still used a water pump to cool exhaust leg) means it's a great flats and shallow water motor since it cannot suck silt, not that this would help for your application.

bottom line based on what i've learned about the 2hp is i like the 4 stroke and the honda aspects (it's a CT50 trailbike motor with a prop!) but i might go for something a tiny bit larger and water cooled if i had to do it again.........

[Zed]

Un-stoppable! That mini jet is really cool.

this makes me wanna have one too! tuna fishing from a kayak is like a dream that i have yet to fulfill:reel::reel::reel::reel::reel::reel:
