A family-operated boat tour company on Curaçao.
We're Seafari Adventures — Captain Adriaan, his family, and our Rupert 50.
Family-operated, Curaçao-rooted
We're a small family business based in Willemstad. Captain Adriaan was born and raised on Curaçao — these are his home waters. We run small-group snorkeling tours, Klein Curaçao day trips, sunset cruises, and Tugboat-wreck and Blue Room boat excursions along Curaçao's west coast. On every captain-led boat tour we run, someone from the family is on the boat. That's not a marketing claim — it's how we like to work, and it's the only way we know how to run a small-group boat tour you'd actually want to come back for.
The boat: a Rupert 50, built in Sweden
We chose a 50-foot Swedish-built RIB called the Rupert 50 — engineered for the Baltic, then shipped to Curaçao. Here's what makes it the boat we wanted under us in Caribbean waters.

Why this much boat
A 5,500 kg deep-V planing hull doesn't fight the waves — it rides over the wave-tops once it's up to cruising speed. That's the difference between a comfortable boat tour out to Klein Curaçao and a kidney-rattling small-RIB ride. We chose mass on purpose: the heavier the hull, the smoother the cruise.
Why a waterjet, not propellers
We chose a Rolls-Royce KaMeWa waterjet over outboard propellers for two reasons. One: jets push water through a sealed impeller, so there's nothing spinning in the water around swimmers and snorkelers — a real safety margin in busy snorkel zones. Two: a jet bites water reliably even in shallow coral areas where outboard props can strike rock. Pilot crews and sea-rescue operators in the Baltic chose this configuration for the same reasons.
Why this specific boat
There are plenty of boats running Curaçao day trips. Most are catamarans built for slow cruising at 8–10 knots, or smaller RIBs built for short, fast sprints. Neither is wrong — but we wanted something different. The Rupert 50 sits in a category most operators don't cover: large enough to ride steady at 30+ knots, small enough to tuck into the Blue Room sea cave entrance, fast enough to cover the Tugboat wreck, Playa Kalki, swim-with-turtles spots, and Klein Curaçao in a single day.
It's a deliberate choice. Swedish boatbuilders spent decades refining this hull for professional pilot crews and sea-rescue services in the Baltic — a body of water where comfort isn't a luxury, it's how people stay productive in hard conditions. We trust that lineage. It means our guests get a premium boat tour in Curaçao that's calmer at 30 knots than most boats are at 12.
Speed without the ride
Most fast boats in Curaçao trade comfort for speed. The Rupert 50 doesn't. You arrive at Klein Curaçao without feeling like you got there. That's the design choice.
Now booking summer 2026
The Rupert 50 arrives in Curaçao end of June 2026, and we open public bookings from August. Reserve a date now to lock it in — we run small-group snorkel tours, Klein Curaçao day trips, and sunset cruises with 26 guests maximum, and the popular Klein Curaçao and Tugboat-wreck dates fill up first. Cruise ship shore excursions welcome.
