🦞 HIGHLINER
— MAINE LOBSTER FISHING SIMULATOR —
Bait. Set. Haul. █
HIGHLINER is a terminal-based Maine lobster fishing simulator. You start with an Eastern 22, 20 traps, and $500 in your pocket. Make it through the season, pay your bills, upgrade your boat, and work your way up to running a real operation.
NOAA marine forecasts, realistic trap economics, grade-based lobster pricing, random events, equipment upgrades, bycatch permits, and a fleet that goes from a 22-foot open boat to a 46-foot Wesmac. The Gulf don't care.
