Bill Fishing Seasons

February thru mid-April

We are Marlin Fishermen.Even though the inshore waters have warmed up this time of year the Marlin are still abundant our far offshore FAD's and seamounts.However, the Pacific sailfish up to 150LBS. are so plentiful inshore at this time that we offer Spinning and FLY trips as stand alone trips or can be combined with 3/4 day overnight Marlin hunts.

Mid-April thru mid-September

This is Marlin season. The bite can be ferocious at times with our Boat one-day record of 17 releases (15 Blues, 2 Blacks) coming in this season. Double digit shots per day are not an unusual occurrence.

Mid-September thru February.

If you have ever dreamed of an IGFA Super Slam this is your shot. We have one of the only fisheries in the world where you have Black, Striped, Blue Marlin and Pacific Sail available all at once. This is our busiest season. Book early for a spot.Want to super size your Billfish tags?We fish Swords all night with underwater lights and fresh caught squid.(we eat the extra bait)

About Thumper

Catch And Release

At TBE we are no-kill on Billfish. As supporting members of the Billfish Foundation we support tag and release; we practice and teach conservation and sustainable fishing ethics.

Thumper the Yacht

Thumper is a 61’-4”loa luxury sportfish custom built by Mikelson Yachts of San Diego. Design is by famed naval architect Tom Fexas for the long range Pacific Fishery.

She features twin diesel mains and gens, modern Furuno electronics with Sat Phone, all USCG safety equipment, on board tender, walk around decks, huge live well, tuna tubes; teak and mahogany interior, full galley, 2 freezers, completely air conditioned, 2 private staterooms with on-suite heads and hot water showers, bunk room and separate crew quarters for 3 on upper deck. Charter Insurance through Lloyd’s.


The TBE Advantage
vs. normal day charters

You get 12 hour days on the fishing grounds. We leave late evening (between 10 and 12 PM) before your first charter day, travel while you sleep, and are “lines in” at first light. We return the evening of your last charter day. You are on the Yacht 4 nights.

No hotel or restaurant/bar bills.

Maximum angler participation— It’s your trip. We will teach you to hook fish, wire, release, rig and allow you to help mate as you are comfortable /experienced to participate. I’ll teach you to run the yacht while fishing... how and when to back down, etc. when fighting bill fish.

Or you can just relax in the 360-view air-conditioned salon and watch the action “in the pit". What’s your pleasure?

Why Golfito?

The traveling billfish angler has a myriad of excellent locations to pursue his or her passion in Pacific Central America from Guatemala to Panama...the majority of these locales are famous for their sailfish bite.

Golfito, however, is home to one of the most prolific MARLIN bites on the planet. The Panama/CR border area is one of the few places in the world where three tectonic plates converge. (Hannibal Bank is on the Cocos Plate and millennia ago was located off the Galapagos Islands in Ecuador).

This intense plate activity has caused crust upwellings and intense volcanic activity that persists today. It is these folds in the earth’s crust and extinct volcanic cones that rise from the depths that enhance the currents and attract the bonito and yellowfin with the Marlin in close pursuit.

...When I first started fishing Golfito there were no FADs. We fished the seamounts. And we still do today with the FADs as additional targets. - H.Glah
