Cracks in Subfloor

Hi All. Wondering if anyone else has experienced what we are seeing...We bought a new 2017 Wellcraft 241 Fisherman in 2018. We are the first owner and purchased with 40 hours on her. At time of purchase, dealer pointed out that there was a small crack in the subfloor (where the porta-potty is located) - in a corner - about an inch long. They had their mechanics take a look and said it should not be an issue. We have thoroughly enjoyed our boat - and live in Tampa, FL. As we put her in for 100 hour service a month or so ago - we noticed the crack had gotten much larger (about 3-4 inches) and appeared to be separating a little. So the marina repaired the crack while they had her for service. We picked up the boat and drove the 40 miles home on the water only to discover a brand NEW crack had developed just behind where they had made the original repair - still in the subfloor - not external. This was last weekend. We contact the marina again - they tell us they will contact Wellcraft. Took the boat out this weekend - low and behold ANOTHER crack shows up - this one is larger about 3-4 inches. It doesn't appear to be taking on water as the bilge pump doesn't fire very often, but is disconcerting to say the least.

Has anybody else had this happen?

How about some pics, kind of hard to get what you mean by sub floor. Are you talking about the raised piece that the head sits on?

Yes - if you're sitting on the head and look down and to the left (port side) is where the cracks are. Attaching pic...

That tells me there's no support under there, with out being there and looking at it I would guess that it only puritans to having the porta potty there. most of the time the support for things like that are spray in foam so that it takes the springiness out of the floor, sounds like a manufacturer issue. Get ahold of customer service at Wellcraft and send pics tell them what's going on and that the dealer has already tried once and see what they say
