Typhoon inflatable leaking seams

[longjohnsilver]

I bought this earlier this year and it stayed up well. However I left it on a dinghy rack whilst abroad for 3 weeks last month and when I returned it had deflated, so I blew it up again and within a few days it was sagging, so over the weekend I looked to see what the problem was and it I found that there were leaks from 2 of the seams between the tubes at the bow and the floor, not the easiest place to get at and effect a repair.

Any suggestions as to how to make a good repair? I'm happy repairing holes but seams are a different matter. It only cost me about £150 but seems a shame to scrap it without attempting to fix it first, but having it done professionally will be uneconomic, so it's down to me!

I used this (see link below ) on an old avon i had squashed against a pontoon when attempting to leave in strong adverse tide .

dinghy started leaking but from nowhere visible , after checking with soapy water found various seams leaking .

used the sealant , simply poured into all chambers affected , pumped up boat and tipped it round a few times to coat all surfaces , its also blown internally to leaks .

bobs yur uncle , very , very effective cure , dinghy would stay up for whole season after , only thing to watch is that you free off the valves , as they can get a wee bit sticky.

this cure lasted for years and when dinghy sold , still excellent (wish I had kept dinghy as spare - now need one !)

most chandlers will have something like this .
