I have this "trapped water" issue with my Mobius V 2000.

Its been like this for the 5 years that I have owned the boat.

I just look at it as extra ballast...

It does get cold here in the UK in winter, so I guess it could freeze solid, but it hasn't before, so I'm not going to worry about it.

Just as a note, my friends 2004 X2 Mastercraft has exactly the same problem, neither of us worry.

Just keep boarding.......
