Leaking Yam 360S dilemma
I have a Yam 360S. Unfortunately it was over inflated on a very hot day 2 years ago and the front chamber now deflates slowly due to leaks at both ends of a short horizontal seam that runs across the blue bow section (on the inside of the boat) where it meets the vertical seams that join the grey fabric to the blue bow fabric.
It has been to the Rib Shop in Hampshire twice for them to fix (or bodge) it. The first time they merely stuck a lop sided big white oval patch over the whole H shaped seam. This had wrinkled when I unrolled the boat for use the following summer and leaked immediately down the wrinkle lines. Also, common sense tells me that you can't successfully stick a patch over a seam. I managed to run some glue down the wrinkles which enabled us to use it but it needed inflating every day.
I took it back and complained, thinking they'd do something better. They didn't - they just bled more glue down the seam and made a mess, then said:
"we have repaired the small leak that was coming from under the patch we fitted September last year and this is now airtight. On testing the patch we have noticed that the seams around the area are showing signs of porosity. Although very minor at present this may get worse with time and is something I am not happy to attempt repair on."
There are no other leaks and the seams are all airtight.
It spoilt 2 holidays and was still leaking this summer before we went away, so, determined to fix it, I bought some of that Polymarine latex stuff called Seamseal that you introduce via the valve, then inflate and roll the boat around. That worked and it held air but unfortunately it only lasted 2 days on holiday before deflating. Another spoilt holiday, slightly saved by applying Polymarine Sealflex (a kind of liquid patch) to the 2 points marked X where it leaks.
So, do I:
Put it in the rubbish/sell and buy another;
Attempt to fix it, if so how; or
Send it somewhere to be fixed, if so where. Polymarine said they'd look at it but the carriage to N Wales is £25 each way and there's no guarantee that they can fix it or that the fix will hold.
