A great addition to any nautical adventure. There are 6 fleshed out ships and crews. Short bits of flavor give you a good idea about the ship and her crews personality. Leaving it open enough for you to add your own flair. The statblocks included aren't bad. The verbiage could use some work. The skills reference "you" instead of the monster/NPC's name, which is likely cause they were probably just taken from the player's handbook. All in all a good product.

The only thing that was a little drag was the lack of any artwork. Dmsguild provides ample source of free art and even drivethrurpg has some free or low cost art. A splash of nice art on the interior would be a nice addition.
