Yesterday I noticed when I came to a stop and there was a rush of bubbles coming from the port side center pontoon. After closer inspection it appears to be coming from around where the lifting strake is welded to the pontoon. I then noticed that it is not "flush" with the pontoon in several places on the port side but is on the starboard pontoon. A few months ago I noticed this as well but it didn't seem to be as many bubbles. Since the boat isn't riding any lower in the waster (thank goodness!) should I be overly concerned about this leak? We did have repairs done to the aft and port siding as a neighbor boat hit the aft port corner with the bow of his boat last year. However, I haven't noticed this leak until recently.
