Colored boats require more upkeep than do white ones, generally speaking. And it looks like the blue one is in need of a "make over", as it is.
Also, the blue one has dead lights/ports in her topsies. Which are notorious for leaking.
That, plus her chainplates are directly afixed to the hull
. And such are more prone to leaks
than ones which penetrate the deck
, & attach to interior
I can't say with any certainty if the ones on the white boat
are mounted differently, but if they are, then that's another strike against the blue one.
