Fish aboard a 60-foot custom Mikelson built for serious blue-water fishing, long-range marlin hunts and multi-day expeditions from Golfito and Puerto Jiménez.
Thumper is a 60-foot custom Mikelson operating from Golfito with service to Puerto Jiménez and the Osa Peninsula.
This is not simply a larger version of a day boat. Thumper is built around long-range offshore capability, extended fishing days and multi-day expeditions.
The air-conditioned interior, full galley, sleeping quarters, private restroom and hot shower make it possible to spend multiple days pursuing blue-water gamefish without returning to port every afternoon.
This boat is designed primarily for anglers committing multiple days to South Pacific blue-water fishing.
Longer and overnight itineraries are quoted according to the fishing plan, destination, fuel requirements, accommodations and number of days.
Thumper’s core mission is offshore sportfishing.
The boat carries professional 30- to 80-pound-class tackle, heavy-duty outriggers, fighting chair, modern electronics, tuna tubes and the systems needed to work remote blue water.
For anglers whose main objective is marlin, the advantage of Thumper is not just the boat’s size. It is the combination of range, overnight capability and a crew accustomed to extended blue-water fishing.
One of the main reasons anglers book long-range South Pacific trips.
Powerful billfish found in Costa Rica’s southern Pacific waters.
Fast, acrobatic billfish frequently encountered offshore.
Powerful tuna that can provide incredible offshore action.
Colorful pelagic fish often found around current lines.
Fast-striking predator and excellent mixed-bag target.
Thumper can do both, but the boat’s real advantage becomes clear when the trip extends beyond a normal marina charter.
Fish South Pacific offshore water for marlin, sailfish, yellowfin tuna, mahi-mahi and wahoo.
Stay offshore longer and reach remote seamount and blue-water areas that are difficult to fish effectively on a normal day trip.
A multi-day fishing boat needs to do more than catch fish. It needs to keep anglers comfortable enough to stay offshore and fish effectively the next day.

The Hostinger listing describes Thumper as being operated by veteran blue-water professionals with decades of experience fishing Costa Rica’s Pacific coast and international tournaments.
That matters particularly on multi-day trips where the crew must make decisions about current, bait, weather, marlin activity and whether to remain in an area or make a longer move.
Thumper is best viewed as a complete fishing platform: experienced crew, long-range boat, heavy tackle and enough comfort to stay on the water.
