Water in iako tubes??

I usually end up dumping water out of my iakos when I take my boat down. What the heck? Am I supposed to have some kind of plugs on the ends of the tubes? It is not the trivial amount of weight but I am sure the salt will shorten the life of the tubes....should make em out of titanium! $$

My Zephyr iakos have foam plugs siliconed in the ends. Try stuffing some in the ends with silicone. Thats how karel makes em .

The foam plugs keep the water from filling the iakos but , they don`t prevent water from filling up the iako reciever hole below the iako. Some boats have a pretty nifty drain hole located at the bottom of the iako reciever hole which completely drains all the water out continuously. Makes for a nice light weight boat.

Hey Shawn
Im sure you know this but Titanium wont prevent the tubes filling up. All you can do is to either plug the ends......inside the pop pin, like fuze is saying.......or fill the iakos with foam, again, inisde the pop pins. If it really bothers you bring em down and I can seal em up lickety split or I can attempt to explain it to you if ya wanna try it yourself.

At some point I did have foam pieces in my tubes, now I know why! Me and my boat are like a barge anyway so a little weight doesnt matter but being salted inside I am sure will eventually rot the tube. I was saying that about titanium because I hear it is the only metal that is totally resistant to corrosion from sea water. Thanks for the help, now I know

My aluminum iakos for my Fusion has foam plugs that came in them. In the front one, there is actually 3 plugs, one at each end and one above the button spring pin.

I agree with Fuzerider on that fact that the receiver hole still fills up with water, but at least with the plugs in the iakos, it won't fill up as much.

After each use, I spray everything down with fresh water to include shooting out the rudder cable guide/tubing and inside of the iakos to get all the saltwater out of those places.

Besides adding a drain hole for the iako receiver in the ama, I wish there was a drain hole for the seat cockpit area as well. I know the foam seat displaces the water, but I still end up with some water under the seat whenever I'm out in some surf or choppy swells. I usually end up draining that water out whenever I get a chance to pull in to the shore.

Cut foam plugs slightly larger than tubes so they slide in snugly. Recommend not securing with silicone so that if/when water does leak in, you can easily pop out a plug and drain.

You could perforate your iakos. That way when water gets into them they just drain out. Plus they will be lighter.

i like th' idee o' cuttin' holes. we ortin' ta do this fer boats as well. that way they can drain water more efficiently.

what boat is these iako's from?

#9 Tue, 08/19/2008 - 8:28pm

rinse your iako's with fresh water after paddling when you wash down your canoe. Maybe spray with silicone (not WD-40). Keep it simple - no need plugs. The added weight when iakos take on water is temporary anyway so no big deal. Enjoy your paddling and don't worry about all those technical equipment things. They make very little difference if you are paddling correctly and surfing well. If you are missing waves or not pulling properly, all the other stuff doesn't matter. Have fun-main thing!

Like the idea of the perforated iakos. Back in the day we used to perforate the water bottles on our bikes to make them lighter for racing.

I dunno about the silicone idea. They might start slipping around and a lot of boats use friction to keep iakos in place.

Jibofo, thats brilliant. In order to make bikes lighter weren't they researching perforated bike tires too? Makes sense. less material less weight.

we should perforate the hulls of our boats too. any weight taken on in water would be vastly outweighed by the weight lost in hull material. I'll see you all at the next race...

Your tires end up perforated one way or another. If you bought them pre perforated, I'm sure that they would charge you extra.

#14 Wed, 08/20/2008 - 9:21am

I guess anytime you get your holes poked you get charged extra...

#15 Wed, 08/20/2008 - 9:28am

I wonder if perforated airplanes would fly higher and faster?

#16 Wed, 08/20/2008 - 11:39am

I think you mostly get charged when you want to poke holes.

#17 Wed, 08/20/2008 - 2:59pm

Seems like that depends on the relationship between the poker and the pokee, Jibofo...

And what about perforating your paddle? Wouldn't that make it move through the water faster? You could catch up to the Tahitians' super-fast stroke rate.

You always end up paying, one way or another.

#19 Wed, 08/20/2008 - 4:42pm

They used to perforate the wings on airplanes, based on the fact that toilet paper never separates at the perforation.

#20 Thu, 08/21/2008 - 6:55am

and costco coupons. They NEVER EVER tear on the perforations.

Yup Jibofo, one way or another you end up paying when it comes to poked holes.
