Ultra Grand Slam - 6-Hour Key West Big Game Charter

The Ultra Grand Slam offers a 6-hour Key West sportfishing charter from Historic Charter Boat Row at Key West City Marina, Garrison Bight. This three-quarter-day trip is built for anglers who want more time offshore than a half-day charter while still keeping the schedule flexible for the rest of the day.

Captain Magnus Nilsson runs the 48-foot Ultra Grand Slam, a spacious sportfishing boat with twin diesel power, air conditioning, a large salon, two staterooms, a stand-up head, fish-finder equipment, and room for up to six guests. The boat is designed for comfort, stability, and serious offshore action, making it a strong fit for families, first-time anglers, and experienced fishermen looking for a bigger Key West charter boat experience.

The 6-hour trip gives the crew time to target productive waters for species such as mahi-mahi, blackfin tuna, wahoo, sailfish, amberjack, and other seasonal Florida Keys game fish. Rods, reels, bait, tackle, and safety gear are included, and the captain and mate help guests with rigging, technique, and landing fish throughout the charter.

Guests should bring sun protection, polarized sunglasses, snacks or lunch, and any preferred drinks beyond what is provided. For current departure times, available dates, and private charter options, use the Check Availability button above.
