As for an individual, there are numerous areas to assess when comparing one boat versus another. We can’t list them all, but a big one is service access. For instance, your engine and transmission will need the filters and oil changed. Are these points accessible? What about the underwater through-hull intakes for the ballast tanks? Can the valves be reached and shut off quickly should a line burst? Is the electrical system orderly enough that one can find a fuse or trace a wire, or does it resemble a bowl of plastic-coated spaghetti? Is all wiring marine cable? That means it’s more corrosion- and fire-resistant, and its insulation more oil- and solvent-resistant than automotive wire. How about audio systems? Are the speakers facing each other directly, which cancels out some of their sonic goodness? Or are they slightly angled so as to deliver the best sound? How is the tower mounted, and what do its welds look like? Do the board racks swivel?
