Voidjammer: New Ship Statistics!

After much internal debate and discussion with my co-GM Jeremy, I have decided to scrap the Voidship stat and combat system that I posted here. The modified ship combat system from the Blood and Treasure RPG is great mind you, but Voidjammer (and Spelljammer) ships are more likely to run afoul of really big monsters, and so monster-esq stats are called for.
So the Ship Stats I will be using are comparable to Constructs and the Apparatus of The Crab magic item (see page 212 of the Blood and Treasure GMG). In essence they are enormous magic items made so by the presence of a Helm (see below).
I will be posting a selection of classic and new vessels soon.

The galleon is the best ocean going craft that groundling nations can bring into space. It is nothing more than a sailing ship with the voidjammer helm-purchased or salvaged from some wreck-attached. Other nations dabble, though, and the most thoughtful of them use the galleon as their vessel of choice. Bulky and slow, it still gets the job done, and its large cargo hold carries a great deal of spoils from other lands.
In my home campaign, the vast majority of voidjamming ships in operation in the sphere are Galleons or smaller, converted sea vessels. Their use in space has encouraged shipwrights to modify these vessels to better ply the spacelanes, giving rise to an ever-evolving standard of ships. This is a basic Galleon, with many having modifications such as glassteel domed decks, coldfire thrusters, and advanced weapons.
