This book is problematic as hell, but that's not necessarily a "deal-breaker".
I got started down McCammon's trail many years ago, as a young child - in the late '80s/early '90s it wasn't at all uncommon to find, in an otherwise normal and successful adult's house, large collections of paperback horror novels. (Now I guess it would just be like life-size Star Wars figurines, so.)
To an devoted R.L. Stine/Christopher Pike enthusiast these shelves proved irresistible; they represented a future where I didn't have to stop liking something that gave me great pleasure but which already registered as a very self-indulgent and weird way to spend large chunks of time. Also the covers were really cool.
You could (and I did) spend hours just picking books up and staring at the chillingly rendered grotesqueries adorning them. And Bob McCammon had the best covers, hands down. The covers of McCammon's books were so cool, and suggested such a richly foreboding and mysterious adult terror, that I never worked up the nerve to actually try reading one.
Thirty or forty years later, some time down the road, Gib Gobs posts a four star review on this website of something called Stinger with a cover, and name attached to it, that look awfully familiar. And I mean "awfully"!
So I started reading these stupid things in order - The Night Boat is the third one, in publishing order, but legendarily (mythically?) it's actually the second that McCammon wrote, after Baal (which was so bad it gave me a stomachache for three days after I devoured it in three hours outside of a Texaco station on Dessau, right by Walnut Creek, w/ two extra large coffees and half a pack of Marlboro Smooths) and before Bethany's Sin (which, we can never let the feminists find out about this book).
All three are bad, and for a while McCammon legendarily (mythically??) deliberately kept them out of print. I think he had the right idea; each is, to varying degrees, thematically problematic, strangely/poorly paced, and embarrassingly over-written. But Baal and Bethany's Sin are pretty fucking hard to put down once you decide (for whatever reason) to pick them up.
The Night Boat is a turgid slog. Its action relegated to a small Caribbean island, the locale provides McCammon a good excuse to do lots and lots of bad dialect, and indulge in flatly racist voodoo caricatures. The plot involves a long-submerged U-boat risen to the surface and the undead Nazis who have been waiting for forty years to just get out of this watery grave and get a plate of knockwurst and resume WWII exactly where they left off.
Lots of nautical action and of course McCammon rises to the challenge, the writing still self-consciously muscly but actually less redundant and overheated than similarly situated material in Bethany's Sin (which, again, is a better book, and we can never, ever allow the feminists to discover its existence), but the characters in the water don't ever come to life, and the book drifts into a truly lazy white savior ending that retroactively negates any goodwill the author earns with the sequences where boats are fighting.
I'm not giving up on Bob McCammon, at least not until I get to the iconic stuff that tantalized my pre-pubescent imagination, but the Night Boat, which every time I referred to by the title in the review here I first typed it as "the Ghost Boat" and then had to backspace it up and retype it correctly as "the Night Boat," is a terrible novel.
There's a moment in the story when a character - who actually is the best, most likable character in the book but still lazily rendered and ultimately just acting in service to the most boring character in the entire book, The One White Guy In This Story Who Isn't An Actual Nazi; this character is representative of the book's most serious failing, that McCammon introduces a lot of potentially interesting shit and then fails to develop the material or deliver any payoff whatsoever - but he drops to his knees after failing in his pursuit of the Night Boat (goddamnit, I did it again, I typed "the Ghost Boat") and says "The Night Boat - nooooooo!!".
This is really a status update on my McCammon quest. I felt compelled to condemn this novel on the public record before I continued along my private path. Not good at all. McCammon was going through some stuff as a young man. I wouldn't care to speculate on the specifics. They say that, with ebooks and all this, novels delivered directly to your digital devices, every book eventually gets the cover that it deserves. This definitely is (currently) true of the Ghost Boat.
