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 14.2-metre 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 is what keeps the boat ride out to Klein Curaçao comfortable. 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
We wanted a boat that is large enough to ride steady at 30+ knots, small enough to tuck into the entrance of the Blue Room sea cave, and fast enough to reach the Tugboat Wreck, Playa Kalki, the turtles at Playa Piskadó and Klein Curaçao without long hours in transit. The Rupert 50 is that boat.
It's a deliberate choice. Swedish boatbuilders spent decades refining this hull for professional pilot crews and sea-rescue services in the Baltic, where comfort is not a luxury but how crews stay sharp in hard conditions. We trust that lineage. For our guests it means a boat tour in Curaçao that stays calm at cruising speed.
Speed without the ride
The Rupert 50 is built to be fast and comfortable at the same time. You arrive at Klein Curaçao relaxed. That's the design choice.
