I'm lovin' this series. The Fantasy City was very good, but Coastal really got me where my RPG heart lives. Growing up in the land-locked American Midwest, I never saw an ocean until I was twelve years old.
In the summer of 1966 my oldest brother was about to head with his Navy batallion to Viet Nam. My dad, knowing that war meant this might be his last chance to see his oldest son, packed up the family for a road trip from Minnesota to New England. (Jim did make it back, although he's one of the many victims, both Vietnamese and American, to suffer from exposure to Agent Orange.)
What that has to do with DMAP #2 is the visits we made to museum ships from Boston to Norfolk along the East Coast.The best of those was (and remains) the Mystic Seaport Museum. It's one of those "community re-enactment" places, having display shops set up with goods as they existed during the 18th- and 19th-century whaling heyday.
Once I started running RPGs, seaside sites became my favorite type of locale for starting my groups out. Over the years, I've accumulated sources for information on tides, storms at sea, and the like.
DMAP #2 ties these together in as nice a package as I've seen, both compact and useful. All that, and more of your wonderful NPCs!
Here's hoping you and your family remain safe and healthy, and having some fun, too.
