What are some of the common failure points for the TI hull? My TI has been taking on water on my last few trips so I decided to do a leak check today. I pumped in some air and did the soap test... nothing (with the exception of the large hull compartment). I went over the entire hull inch by inch, inside and out. I pressed on the hull around the drive wells... no cracks. To be honest I was quite impressed with the integrity of the hull. I have a 2013 and it looks like everything was reinforced well. My last two trips where in calm water, so no water came over the bow. I'm stumped. I appreciate any help, thanks folks!

Also, what are these on the bottom of the hull. Possible leak point?

They are just covers for brass inserts that either anchor parts on the inside or are used to attract more plastic to an area while in the mold. Mostly cosmetic.

Thanks Bob. I was curious if those where possible leak locations. When I checking inside the hull those locations corresponded to an area of thick plastic. Like I said the integrity of the hull seemed great, that is why I am so stumped on water intrusion on a calm day. I don't know... maybe the drain plug wasn't in all the way. I am going out tomorrow, we'll see what happens.

Could be scupper hole damage, or a crack under your seat. Those things are hard to find.

Sometimes the footwell cracks don't reveal themselves unless you're pedalling.

I would do my next test on the water, with sets of dry towels in the hull. Go for a sail and a pedal for about 20 minutes and check them out.

Went out today. Emptied a gallon of water out of the hull after a 2 hour, very wet ride. I think the leak is near my aka braces... had a lot of water come over the bow.

Most likely it is just the front hatch seal, but keep at it to be sure.

You may also want to feel around inside the front hatch area. We have discovered quit a few with cracked "cups" where the molded plastic parts are screwed in, especially where the front hatch bungees are mounted.

I have the same problem in the last 2 rides. calm water but had 2 gallons for 3 hours trip. now thinking about a decent bilge pump first.

have just passed the warranty. do you think hobie will replace or at least fix the hull if it really cracks?

I'm from hong kong.

The warranty is for two years, but simply file a claim. We (or in your case... Australasia) can review. If there is a fix we can let you know. If not we can consider coverage if it is deemed a manufacturing defect.

If you do a pressure test and still can't find the leak.
One thing you can try to eliminate the possibility of the front hatch being the problem would be completely seal the outside of the hatch with masking tape to seal it then go out. If you come back with a lot of water in the hull then you for sure have a crack somewhere else that you will have to find and fix.
I know on my TI when it gets heavy, my stern goes under quite a bit, and if the rudder line guide tubes are not neatly tied to the underside of the rear hatch, they may leak water. If they are tied up high they create an air bubble that prevents water from coming in thru the tubes.

I know on my TI if it's a real calm day I will get no water at all in the hull. On a heavy sailing day where waves go over the bow a lot, I will get about 2 cups in the hull, which I think is pretty normal on TI's. I have spray skirts and the seem to help a lot. If you are getting a couple gallons changes are your leak is below the waterline I would start looking there, especially in the mirage pockets.
Hope this helps
Bob

9 Months later and I found the leak! Granted I did give up a while ago. I happened to find it by chance. I saw water coming out of it while cleaning the inside of my TI. It is in a scupper hole under the seat. The molding from the top and bottom part of the kayak are off center and don't match up well. Looks like it created a weak point and a crack. I can't believe it took me this long to find it. I still have a few months left on my warranty. Hope to get it fixed soon...fishing season is about to fire up.

Great you kept at it (sort of) and finally found it.
