I recommend color or thematic variations to make this more appealing / expressive.
Like Space Pirate ship with neon coloring; a Dragon themed ship might have claws & teeth on the under-side & front; or elemental versions in an expansion of this pack.
The long-boat has the most appeal in this base set since it has touched of blue, notches in the middle & an animal head on the front.
(Just my opinion / 1st impression 🙏)
