Putting in internal shelving and counter tops has taken me forEVER. And when it's done it's all so......small. Gotta fit it around this and that, take this and that into consideration, plans are crap as my brain appears to be dead. Complex fittings take multiple trips out the boat, down the ladder, into the shop, do the tiny little cut, back up the ladder, into the boat....................and so on. Seems to take six trips for every cut and fit. Curse of the boat being too small for the jointer and bandsaw and table saw and a few tools to fit below. A guy oughta only build big boats....while he's young, fit and can still viualize well in advance.
Oh well, gettin' there....
