Same happened to mine 2006 a couple of years back, I put a large patch over it and it worked I did notice the leading edge is starting to lift which should be being done again as it is in for a hole in the front tube as from yesterday!
Got a frantic call from the Mrs H that she had managed to hole the boat and it was going down, I'm 220 miles away!!
Gave my very helpful Boat man Chris Turns a call, to make it worse I have the trailer back here, no problem he will get a trailer and meat Mrs H at the slip.
Call Mrs H back 20 mins later she is at the slip and he is backing down with a trailer ready top man
