I was taking on water in my '09 Adventure and did a leak check. Found a crack in the seat peg hole. Spoke with dealer, we figured Hobies adjustable seat pegs are causing stress at this point, resulting in the crack.

Was wondering if anyone else has been experiencing the problem. I think Hobie has an epoxy/plug repair for this. I e-mailed Matt, just waiting for his reply. I'd like to put this epoxy/plug reinforcement on my Sport and Oasis as a preventative fix before a crack develops in the future.

Had that happen with 2 different Adventure kayaks (red). Split seat pegs are not dangerous but any water that spills into your seat will leak into your hull. Opening the seat scuppers only makes it worse because instead of draining the water it lets a little water into the seat area and in the peg crack.

A 3/4" PVC end cap fits nicely over the the peg hole from inside the kayak.

Flip kayak upside down on a pair of saw horses so you can work on it. Pour some epoxy into the PVC cap. reach in through the center hatch, and put those over the seat plugs. The upside down boat lets gravity help keep the PVC caps in place until the epoxy dries.

Best glue is 3M Scotch weld dp8010.

Once patched - no more problem.

BTW it is a hard leak to catch because when the seat is removed the crack closes up. With the seat installed the seat peg expands the crack for more leaking, but hard to spot because the seat is in the way. Best way is using a spot light inside the hull - like candling and egg.

Thanks, Yak. That's what I was planning to do as a fix and a preventative measure on all the seat peg plugs. I was surprised to hear Hobie didn't send out a memo to the dealers when the problem was first discovered. My local dealer is always very up to date on all Hobie issues and this was a first for him. For Hobie to come up with a repair kit shows the problem has happened before!

Any other 'weak areas' I should be on the look out for?

Very good description of finding the crack, but I am wondering how many folks know about candling an egg. Thanks for the help.

"Candling is a method used in embryology to study the growth and development of an embryo inside an egg. The method uses a bright light source behind the egg to show details through the shell, and is so called because the original sources of light used were candles."

http://en.wikipedia.org/wiki/Candling

:lol: I couldn't think of any better analogy. Of course in this case the bright light shows through the boat hull to reveal cracks or thin spots.

I realize now most people want there eggs "over easy" or "scrambled" and not "candled"... :D :lol:

The seat plugs on my Outback and Sports have never shown the crack issue. Matt explained that the Adventure hull's rear seat plugs are in an area hard to get the plastic drawn up into the mold. So there may be a few seat plugs that are a little thin and may crack. The PVC trick is all the fix needed. I would not suggest welding.

bjb - to answer you question, there does not seem to be any other thin or crack prone areas. Mirage drive well fronts have been reinforced with brass inserts and the click-n-go drive replaced the cam locks; which fixed the odd few cam columns cracks on earlier boats.

The only other "gotcha" is user created. If loading or unloading the adventure on concrete you need to protect the bottom of the stern (the skeg) from rubbing on the concrete. If not you will rub a hole in the boat - avoid skeg rash. Bungie on a knee pad to the stern or put a piece of carpet on the concrete.

Do you know WHY eggs were 'candled'?

I have used 3M Dp8010NS. Great stuff. I called 3M and discussed my application. They told me to use NS in that the NS doesn't sag. I used the 3/4 PVC end caps on my seat pegs. Additionally, I used a electrical pvc pipe (cut in half) on my drive columns and some NS on the cart holes. I recently upgraded to turbo fins and was concerned about cracking the drive columns.

Hopefully these preventative measures that were trying will not void warranty.....What's your thoughts Matt?

I've had the same problem on the seat plug by the right side of the seat where the dagger board's bungee cord is threaded through on my Adventure Island kayak.

But in addition, I have found other cracks where the front hatch is. The black plugs where the bungee cords are threaded into the kayak have a similar threaded "cupped" area the same as said black plugs to thread into. Since this area is constantly be exposed to waves washing over them, water was leaking in very badly.
When I un-thread the black plugs I noticed pretty large cracks in all for "cups".
I don't know if this is a problem that Hobie is acknowledging as I can see this is a weak area and I am not sure how this could have happened except that perhaps at one time the kayak's previous owner had compressed the hull of the kayak at one point.
I conclude this since upon putting light pressure on hull, I noticed that the cracks widened as the hull flexes.

I would suggest Hobie reinforce these "cupped" areas in there future designs.

I will use the pvc cup suggestion on all the cracked "cupped" areas as I am confident it will reinforce the area adequately.

Has any ever tried using pvc glue on Hobie kayaks, and does it adhere to it the Hobie material?
If not I will use the suggested 3M glue recommended in an earlier thread.

Thanks.
:D

This is difficult as the holes are humps in the mold. The boats do vary in thickness a bit.

I am still getting water in seat pegs after using Hobies repair kit, apparently the cracks extended past where the pvc caps meet the bottom of hull. Also have the cracks in the front hatch area. Time to put in a warranty claim. This is on an '09 Adventure. Are certain colored models more prone to molding issues?

Starting to wonder if these kayaks are being adequately inspected before they leave the factory! Warranty is great, but how about quality control??

There are a LOT of nooks and crannies to inspect and most thin spot issues are really hard to detect. We'll keep trying for better inspections.

I also wonder about the QA. There is a hole under the bungee end at the fore hatch which they tried to repair in the factory before shipping my new TI. The "repair" was really a botch job. I still do not know how this serious leak can be repaired. I am awaiting an answer from the Swedish dealer/Hobie. For details see. viewtopic.php?f=75&t=30171

Ok, I was sorta ill and busy with family things, but about to finally get to use my (purchased new from dealer in 2009) kayak, 2009 Outback, never been in the water yet, stored under a car cover and a tarp beside a house and annually cleaned with Hobie Cleaner/conditioner and 303. Stored on a trailer, top up. (Car cover keeps UV rays off, but allows water through so it drains thru scuppers so water weight doesn't build up on top of a tarp-like swimming pool, weighing down/deforming the bottom of hull on trailer)


Anyway,
I uncovered it, was going to flip it over and it's HEAVY it's full of water with green moss growing in it/algae .... drained it ... and started looking ...

Bottom is fine (water didn't drain out from interior) crack in the bungie cleat hole in the front hatch and crack in the hole on the kayak where the left front webbed strap attaches to fitting. All rear and other "cups" feel ok that I can reach, but those 2 are obvious cracks. About an hour drive to the city where the dealer is, so I'll see about a PVC caps and 3M Dp8010NS and just do every "cup" in there ..... cause "looks to be" that the fittings were screwed in too far/overtightened? .... Anyway, I will try to fix it,because if I take it to the dealer to fix, I'll have to buy a Revo 11 for myself and give the Outback to my niece or trade it/sell it... but I worry about the cracks "growing" later .... Guess if they do, I'll get to plastic weld or something.

Well, I live in a small town ...so online I tried to find 3M Scotch Weld Dp8010NS and every place wanted me to buy a case so I called the Hobie Dealer closest to me to see if they knew where to get some and he says bring in my Kayak ... I'll try to do that next week to have him give it the water-worthiness once-over .... and just watch .... I'll end up with a new kayak too. Maybe not, my trailer only holds one ..... so far. (I bet my niece bribed him ... she wants a kayak, the boy across the street bought the one I owned in 2007-2009 and I wouldn't let her on my 2009 Outback because "it's new and no one can ride it until I do"

So I'm making a list of restaurants in that city where I want to eat and things to do that aren't in my small town. Might just make it into a mini-vacation I seriously need :)
