Stratos Dutch Built 50 Video Review: A Carbon Dayboat for Rough Seas

The Stratos Dutch Built 50 is a 50 ft dayboat built in the Netherlands for rough water. Stratos makes its carbon fibre in-house, from the 250 kg hardtop to the helm seats. We walked her at a boat show, from the bronze hull fittings to the owner's cabin. The cockpit table drops into a sunbed under a hardtop that slides open, the galley hides behind a fold-out panel, and below there is a U-shaped saloon, a head with a rain shower and an aft cabin.

A dayboat built for the weather

Stratos says this boat is at its best when the weather keeps others in port. The hull flares out for stability at speed and in a swell, the rub rail is extra thick and the water outlets are bronze. Up top, the superstructure is carbon, made in Stratos's own facility. Every surface we touched felt built to last.

What stood out on board

A carbon hardtop that opens
The 250 kg carbon hardtop slides back at the touch of a button for sun or fresh air at the helm.
A table that becomes a sunbed
The carbon cockpit table drops, filler cushions go on top and the lounge turns into one big sunbed.
Drawers that present themselves
Push a button and the galley drawers slide out with the cutlery. Glasses sit in foam so they never rattle.
A window in the hull
A large window by the cockpit seating gives a clear view of the water.
Seats on gas shocks
The helm seats sit on gas shocks to soak up hits in rough water.
A garage of toys aft
Under the sunbed there is storage with charging for Seabobs and a pump for paddle boards and fenders.

The verdict

The Dutch Built 50 looks aggressive, and the build backs it up. The carbon hardtop that slides open, the table that becomes a sunbed and the galley that hides behind a panel make the deck flexible, and every fitting feels made to take a beating. Below there is real headroom, a plush saloon that becomes a second bed and a head with a rain shower. If you want a dayboat that handles bad weather, this one is built for it.
