It's a pain as well on my B33.
Catch 22 if you're trying to balance it: Only thing I can think of is to add spare water supply on the port side (under the seating). Reserve water supply and it'll counter it (not by much). 100L = 100Kilos.
But once you go for a trip, then you'll add more weight in the starboard locker and back to square one!
guess, we have to live with it. On the other hand, it should give us nice sailing on SB tack - lol
