St. Thomas [1] is the base of the largest sportfishing fleet in the Virgin Islands [2]. Sportfishers depart daily from marinas along the east end of the island, many headed to the North Drop, a famed fishing ground in the British Virgin Islands. Some sportfishing expeditions last at least a few hours; many last all day. Half-day trips begin at $700; full-day trips cost $1,200. A direct-to-the-North-Drop day trip will cost extra. Prices are quoted per boat, not per person. All bait, tackle, fuel, and beverages are (usually) included.
Marlin season is in the summer, when the waters are at their warmest. Marlin are tagged and released. Other sport fish, such as barracuda, wahoo, tuna, mahimahi, and jacks, can be kept; most boats will cut a fillet for you if you ask.
