Answer: GAME

To solve this puzzle, you must inhabit the mind of someone playing Battleship. Each space on the grid falls into one of two categories:
  1. A word indicating that you did not hit anything (MISS, VACANT, SPLASH, BUNGLE, EMPTY, or WATER)
  2. A word that is just one letter off from the name of a type of boat or ship.

Transform each "hit" word into a ship and extract the new letter:

Bloop to
SLOOP

S

Custer to
CUTTER

T

Spied to
SPEED

E

Prim to

A

Retch to

K

Puny to

U

These extracted letters spell words that are laid out like ships on a Battleship board. Again, the words are one letter off of the name of a ship or boat. Order the "boats" by letter length to extract the answer:

tux to TUG = G
rift to RAFT = A
steak to STEAM = M
tinder to TENDER = E

The answer is GAME.
