What this demonstrates is a lack of interest on the part of the owner.
Photo 1 didn't happen overnight due to a small leak, what you're seeing is neglect. When I'm looking at a boat I'm checking all the areas that require extra effort to maintain - the prop shaft, the
battery connections, the lower reaches of the engine, the
electric wiring, the genset cabinet, etc. There are plenty of older boats on yacht world where the owner clearly invests time and
money into keeping their boat in great shape, and it's readily visible. The example you cited, in my opinion, is just a hint at the overall lack of
maintenance.
