24' Boston Whaler (Dual Engine) — Marathon
If your idea of luxury is the freedom to design multi-day plans—sunrise fishing runs, sandbar lunches, and evenings moored under starlight—the 24' Boston Whaler from Marathon is built for it. The twin Yamaha F150s offer reliable speed and fuel efficiency for offshore or inshore runs; capacity for eight people makes it an efficient choice for families or groups. Standard features like an Infinity Bluetooth stereo, a custom t-top with outriggers, a swim ladder and a 10" Garmin color GPS with sounder mean you get both comfort and capable navigation for exploring reefs and channels.
The operator lists weekly and seasonal rates and includes complimentary delivery and pickup, which simplifies logistics if you plan a longer stay. Rentals run from one to four weeks, with fall discount and high‑season pricing tiers specified by the provider. This boat is a straightforward luxury option for experienced boaters who want autonomy on the water—bring provisions, coordinate a Saturday delivery, and expect a practical, well-appointed platform for fishing, snorkeling and island-hopping.

Full Day Offshore Charter — Islamorada
For anglers aiming to reach 10–25 miles offshore and pursue big-game species, the full-day offshore charter out of Islamorada is built around one objective: sustained time on productive grounds. The private charter carries up to four guests (six in some small-family configurations) and arrives fully equipped with bait, tackle and fishing licenses provided by the captain. A posted cooler with ice keeps catches and refreshments fresh, and the captain will advise which species are in season—Dolphin (mahi-mahi), Tuna, Wahoo and Sailfish are among the targeted fish.
Operational notes from the provider are practical: bring non-glass beverages, sun protection, a camera and snacks. Gratuity is not included in the charter fee. For a luxury angling day that prioritizes time on the bite and a private crew experience, an eight-hour full-day charter offers the best window to find big-game action while keeping the comfort and service expected from private fishing providers.

3/4 Day Offshore Charter — Islamorada
The 3/4 day offshore charter condenses offshore opportunity into a six‑hour window ideal for guests who want intense fishing without the commitment of a full day.

The private group size (up to four, occasionally six for small families) and included gear, bait and licenses make this option turnkey: show up ready to fish, with the captain handling equipment and local knowledge.
Practical guest guidance mirrors other charters: pack non-glass beverages, sun protection and a camera; the captain supplies a cooler with ice. As with the full-day option, gratuity is not included in the listed cost. For a luxury traveler who wants offshore thrills without an all-day commitment, this mid-length charter balances action and convenience.

Activities include foot pushes, dorsal tows, belly rides and gentle rubs—moments designed to showcase dolphin agility while keeping interactions controlled and personal. The operator frames the experience as 'giving back': every Big Heart Swim funds a one‑time scholarship to Island Dolphin Care for an individual with disabilities.
This program is ideal for travelers seeking a boutique marine experience that connects leisure with mission. It’s suitable for guests ages five and older, includes a facility tour, and centers on hands‑on interaction under staff supervision.
