I imagine a man-o-war appearing as more or less a longer and wider galleon with a 6 cannon broadside, my version having two triangular sails in between the front two masts and from the foremast to the bowsprit, respectively. It has a 6-spoked capstan to match its six crew. It has two harpoon launchers on the stern, too, on a raised section reminiscent of the galleon's bow.
Also, a frigate, being a four masted ship with 4 cannons per side, per deck, and 3 decks total. Once water reaches some ways up the top deck, it's pretty much gone due to the large cannon ports on the sides, which are also capable of being bailed from. It has two capstans of four spokes each, and eight crew to match, and two top-upper deck staircases as well. The bottommost deck of it is split into two, with one staircase at the fore end of the ship going to one bottom level, and a staircase at the aft end of the ship going to the other. The one middle staircase serves as a major choke point, but not one which can easily be blocked as it can be approached from both sides by new spawns. It has a near identical raised platform for rear harpoons, and the bowsprit sits on a platform a floor lower than the half-raised deck behind it, with a staircase leading to it.
As for skeleton lord ships, particularly an ashen lord like that one was, I had two ideas for ships. One is essentially a frigate with a galleon on each side, however the bottom-most decks of the galleons and the two bottom-most (the split one and the one above) decks of the frigates fill separately, while the middle deck of the frigate, as well as both top-most decks and the top and upper decks of the galleons are connected and flood as one. The other idea is two frigates end-to-end, one with the stern removed and one with the bow removed to serve as a very large hull. It bears an entire sloop with a full kraken skeleton strung from it as the bowsprit and figurehead, and some other interesting features such as its many crow's nests and platforms between the masts, with an open kraken mouth adorning the top-most one.
