Ultra Grand Slam Fishing 6hr Day

The Ultra Grand Slam Three Quarter Day Charter is built for anglers who want more time on the water, bigger fishing opportunities, and a private Key West sportfishing experience designed around chasing serious fish. Departing from Historic Charter Boat Row at Key West City Marina at Garrison Bight, this 6-hour private charter accommodates up to 6 passengers and gives guests the time needed to reach productive fishing grounds while still keeping the day flexible and manageable.

Guests ride in comfort aboard the Ultra Grand Slam, a 48-foot sportfishing boat known as one of the largest charter boats on the dock. The vessel features a spacious layout, twin diesel engines, air conditioning, a large salon, two staterooms, an onboard restroom, quality fishing gear, bait, safety equipment, and fish-finding technology to help put anglers where the action is.

Led by Captain Magnus Nilsson, known locally as Key West’s “Fishing Viking,” Ultra Grand Slam delivers a true Key West deep sea and sportfishing experience. With six hours on the water, guests have more opportunity to target larger fish, explore productive offshore areas, and enjoy the excitement of bringing in something memorable.

This Three Quarter Day Charter is a strong choice for visitors who want more than a quick half-day outing but do not need a full-day trip. It is well suited for families, small groups, first-time anglers, and experienced fishermen looking for a private Key West fishing charter with more time, more comfort, and more opportunity.

Guests should bring sunscreen, sunglasses, a hat, snacks or a picnic lunch, drinks other than water, a mask if desired, and plenty of energy. It is also customary to tip the mate 15–20% for their work throughout the trip.
