The Jetten 50 MPC Fly is a clever attempt to combine the best elements of steel and GRP, with a GRP flybridge moulded onto a steel hull.

Not only does this save two tonnes of weight where you least want it, but it also makes it easier to create the complex curves that contribute to its contemporary exterior styling.

Don’t be misled by those softly rounded looks, this is still 26 tonnes of premium Dutch steel with double-glazed windows all round, single or twin diesels on shafts, a small keel and optional Rotorswing stabilisers giving it the seakeeping abilities of a small island.

Most engine options only reach displacement speeds but if you can stomach the fuel bills the twin 380hp Cummins will push the Jetten 50 MPC Fly (and a mighty bow wave) up to 16 knots.

More relevant to most will be the 12l/h fuel burn of the smaller twin engines at 7 knots and noise levels akin to the reading room of the Bodleian Library.

The three-cabin layout includes a full-beam master with an offset double berth, ensuite bathroom and a walk-in wardrobe, a generous VIP cabin forward and a clever third cabin with twin Pullman bunks that converts to an office when not on guest duty.

The abundance of natural light and views from all those hull and eye-level windows is particularly impressive for a steel craft and is repeated at main deck level courtesy of those extra-deep side windows.

The flybridge is the one area we feel still lags behind the best GRP craft with a ladder (rather than steps) leading up to it and a central helm position surrounded by a horseshoe of predominantly aft-facing seating.

It’s a sociable enough layout for passage-making or sunbathing but eating alfresco is best left for the spacious aft cockpit.
