LELYSTAD – True to tradition, KM Yachtbuilders will again show some of its rugged, all-weather, all-region sailing cruisers at the Sept. 4-8 HISWA-in-Water Boat Show. The yard will display 2 unpolished-aluminum Bestevaers, a brand that is the fruit of long-standing

Bestevaer 45

collaboration with Dykstra Naval Architects: the Bestevaer 49 (Katharos) and the Bestevaer 45 (Lene).

But new this year – and sit down for this one! – is a custom-built, 11.15m River Tender, also with no lick of paint or antifouling. KM Yachtbuilders unveiled the craft in July.

The craft — the yard speaks of a workhorse — lacks luxury features. The River Tender has only 4 seats and a steering station inside a very modest cabin. Don’t look for a toilet, a galley or a lounging area. There is lots of storage room up front and aft.

“The main purpose of this tender,” says the yard, is to ferry people from, say, a riverside home up, down or across a river for shopping, running errands, whatever. “This yacht will be hauled out each evening.” The River Tender is powered by twin 440HP Yanmars achieve a top speed of 40kn in combination with jet thrusters. The cabin is sound-proofed to 67dB while going full throttle.

The River Tender – 11.15 x 3.65 x 0.70m (36.6 x 12 x 2.3ft.) – is the work of Austrian builder and yacht designer Harry Miesbauer.

Possibly no builder is more loyal to aluminum than KM Yachtbuilders. The yard says the material cuts building and maintenance costs, is easy to repair, does not rust so requires no coats of paint. Aluminum reacts with oxygen in the air which produces a thin, protective layer of aluminum oxide on the outside of the metal. Also, an aluminum hull is stiff, so it behaves well in heavy swells and choppy seas.

Importantly, an aluminum hull may weigh up to 50% less than a steel one. A lighter hull offers better performance, a shallow draught, lower fuel consumption, less capital outlay for engine and propulsion systems.
