I own a fishing boat. 
Do you sometimes call it a fishing vessel? That is another name for a boat used to catch fish in the sea.
We mostly call it a fishing boat, but yeah! It's a fishing vessel, more for recreational use though.
Ah yes so it falls into one of the three categories of fishing vessels, commercial, artisanal, and recreational.
Oh interesting! What is an artisanal fishing vessel 
Much like recreational fishing vessels it is sometimes difficult to estimate the number of artisanal fishing vessels, they mostly refer to a unique fishing vessel built for a specific purpose.
Ahhh I see. We live in Florida, so there's quite a few different kinds of fishing vessels whenever we go out on the water.
that makes a lot of sense, prior to the 1950s you would see a larger variety of fishing vessels on the water, after that they became more standardized.
Is that for safety reasons? What are most fishing vessels made out of nowadays? 
Most smaller vessels are made of fiberglass, while larger vessels are made of steel.
