Chase Marlin Aboard a 31ft Bertram: Wetass Sportfishing Charters in Guanacaste

Off the wind-swept Pacific coast of Costa Rica’s Guanacaste Province, Wetass Sportfishing runs half- and full-day charters aboard a 31ft Bertram Sport Fisher that fits up to four anglers. Departing from coastal launch points across Guanacaste, these small-group trips promise direct access to blue-water structure—steep drop-offs, offshore seamounts and current breaks where billfish, yellowfin tuna and dorado feed.

Aboard the Bertram, the ride is intimate and focused. The boat’s deep-V hull and classic sportfisher layout give anglers a stable fighting platform and plenty of cockpit room to work a spread. Half-day (4-hour) trips are ideal for families, mixed-ability groups or anglers chasing inshore and nearshore species; full days (8-hour) push farther to productive blue-water grounds where marlin and big tunas live. Rates are posted at $1100 for a half day and $1950 for a full day, for up to four people, which makes this an efficient option when you want serious fishing without a crowd.

Fishing here follows the ocean’s rhythms. Guanacaste’s seasonality brings migrating billfish in thicker numbers during warmer months, while cooler upwellings concentrate baitfish and create explosive bite windows year-round. Expect conventional tackle, live-bait opportunities and trolling spreads in the morning, with casting or kite tactics when fish are actively feeding. The crew runs a compact operation that emphasizes safety, responsible handling of billfish, and fast turnaround on hookups so every angler gets quality time at the rod.

Why Wetass Sportfishing stands out is simple: small groups, a classic Bertram, and direct access to the productive grounds off the Papagayo and Gulf areas. For anglers who prefer a hands-on experience and a high crew-to-angler ratio, these charters reduce downtime and increase the odds of multiple shots at trophy fish. The operation also dovetails with the local sportfishing economy in Guanacaste, where maritime know-how and prime habitat converge.

Practical notes: bring sun protection, seasickness remedies and a camera for those gaff-to-photo moments. Expect check-in instructions and local launch points from the operator after booking. Whether you’re after a family day on blue water or a focused chase for pelagics, Wetass Sportfishing offers a compact, capable platform to chase big ocean days in Costa Rica’s productive Pacific waters.

Bookings typically include fuel and basic tackle; confirm what's included with the operator before arrival so you can plan for tips, licenses or specialty gear. Morning departures take advantage of calmer seas and active surface bites; afternoons can produce calmer winds and different species working on bait schools. For photographers, low sun angles along the western horizon create sharp contrast on fish and tackle during late afternoons. Families appreciate the small size of the boat for easy communication with crew and quick returns to shore if needed. Perfect for private, customizable trips.
