Puzzle 64: Sunken Treasure
Battleships

E-mail me the treasure (4-letter word) to get a free puzzle request (of reasonable size, aka 10×10 for the usual genres that I post). Don’t spam me. Only 5 requests offered.

Hint: There are two words, or to be precise two 4-character strings. One is supposed to be a check whether you are in the right track (if you find it and it makes sense, you’re in the right track; the treasure is the other one).

Meanwhile, this might probably be the last puzzle for a while, while I’m going to fix all previous puzzle posts to follow the current template.

EDITS:

Hint 1: You don’t need to solve the puzzle in order to find the treasure.
