Futura mk2 hull
Finally got round to getting a trailer for my Futura mk2. Inflated boat and all good except the inflatable keel which keeps losing pressure. Changed valve from spares kit but still deflating. Other problem is that the hole in inflatable deck doesn't line up with the valve so have to deflate hull every time I need to pump up keel. It's only 2 years old.
Any suggestions on how I can check for a leak in keel? Perhaps remove deck, pump up keel and put water into boat to see if there are bubbles anywhere?
