The Billfishing Calendar

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, Pacific sailfish up to 150 lbs are so plentiful inshore that we offer spinning and fly expeditions as stand alone trips or they can be combined with 3- or 4-day overnight Marlin hunts.

Mid-April thru mid-September

This is Marlin season. The bite can be ferocious! Our one-day record of 17 releases (15 Blues, 2 Blacks) came during this season. Double digit shots per day are not an unusual occurrence.

Mid-September thru January.

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).

Marlin Mayhem now off Golfito

February 15, 2020

In the last few weeks there have been 2 major tourneys in Pacific Costa Rica: the first leg of the Sueños and the Rockstar out of Quepos. Approximately 50 professional boats in each, fishing 3 days or 300 boat days. The reported Marlin catch was about 70 total or 1 fish per 4 boat days. If this was, for example, the Big Rock or one of the Gulf Coast tourneys that might seem like a lot of Marlin, but this is Costa Rica where daily double digit shots on Blue/Black Marlin is the norm. In fact, these results are the reality in the dry season (January, February, and March). The water begins to warm, which the Sails will abide, but the main body of Marlin seek cooler water. Understanding this historic reality, in conjunction with my Capt. Tommy Lynskey, last November we took a shot and deployed a deep offshore FAD on a remote seamount. This week, leaving Fishhook Marina here in Golfito at 5 pm, we cruised all night to arrive at this virgin locale at first light... The sonar showed massive schools of bait in the area and as we set out our bait rigs they were immediately covered with Bonito, rainbow runners and YFT, with flying fish scattering about. This alone does not guarantee the Marlin are present as our inshore FADs that produce April thru Dec. are also full of bait but only produce Sails with few Marlin bites... However, this time, after loading up on a day's bait and setting out our standard bait and switch spread, within 15 minutes we had our first Blue Marlin crashing a short rigger teaser. Over the next 2 days we raised over 30 Marlin, fought 14, released 10 plus 9 Sails. We leave again tomorrow night with Josh Jorgensen and his BlacktipH team to return to the spot for 4 days to test the best of the new spinning rigs on the bite. Watch for the videos over the next few weeks. Also the story of our Marlin Hunt last October with Sam White, editor of Marlin magazine, will hit the newsstands with video links in the upcoming March Issue. True happiness does not come with spending money on things, it comes from spending money on experiences. Contact us now and come get some...

The TBE Advantage
vs. normal day charters

bulletted list item indicator

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, Costa Rica, however, is home to one of the most prolific marlin bites on the planet. The southern Costa Rica/Panama 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 bonito and yellowfin with the marlin in close pursuit.

When I first started fishing offshore from Golfito there were no FADs. We fished the seamounts. We still do today with the FADs as additional targets.
