2026 Onslow Bay 37 Tournament Edition

Los Sueños, Costa Rica

Triple Mercury V10 400s | Approximately 100 Hours | Dry-Stacked Since New

This 2026 Onslow Bay 37 Tournament Edition is an exceptionally equipped offshore center console built for serious tournament fishing and extended days on the water. Presented in next to new condition, she has been dry-stacked under a full Sunbrella cover. Her triple Mercury V10 400s have approximately 100 hours, are current on service, and are ready for their next adventure.

Configured for the world-class offshore fishery of Costa Rica, This 37 Onslow Bay features a custom Freedom Marine collapsible tower with a removable buggy top, Marsh Tacky 22-foot carbon-fiber collapsible outriggers, Gemlux Bluewater bases, 22 Gemlux rod holders, and a Birdsall four-rod cockpit rocket launcher. A tackle-center leaning post with a slide-out Frigid Rigid cooler rounds out a highly functional fishing layout.

Her electronics package includes dual Garmin GPSMAP 8616xsv displays at the helm, a Garmin GPSMAP 743xsv in the tower, a Garmin VHF 115, and an Airmar B175L transducer. Additional equipment includes a NewMar Phase Three smart charger and Livorsi trim tabs.

Comfort and finish are equally well considered, with upgraded diamond-stitch upholstery, a Llebroc triple helm bench with bolsters, white powder coating throughout, and two refrigerated helm cup holders. A Fusion Apollo MS-RA800 sound system, complemented by Wet Sounds speakers, subwoofers, and amplifiers, completes the package.

Currently located in Los Sueños, Costa Rica, ideally positioned to take advantage of some of the Pacific’s premier roosterfish, yellowfin tuna, sailfish, and marlin fishing grounds. Whether you are looking for a turnkey platform to fish Costa Rica or an opportunity to bring a highly equipped late-model Onslow Bay back to the United States.
