I love making maps with that include ships however there is a very limited selection to pick from so my suggestion is to add more ships and a wider variety of them.

Some types of ships I think should be added or expanded are,

River type ships such as a Caravels Cogs and Sloops.

Merchant vessels like Sloops, Hulks, Carracks, and Hoy's.

Fishing vessels like a Balinger.

Costal vessels and costal defense vessels.

Warships- First-sixth class ships of the line, frigates, and corvettes, for example. (Plenty more types that could potentially be added to).

It would be great for some of the vessels above were also added for most map types.

Any feedback is welcomed.
