More information about the Koopmans 36

This Koopmans, with its long S-shaped hull, is built for sailors who value solidity and safety. The vessel exudes reliability and offers great comfort on board with its large bridge deck and spacious cockpit. It features many stainless steel components, including the rudder blade, cockpit, through-hull fittings, anchor locker, anchor roller, and a protective shear on the rubbing strake; these not only ensure durability but also give the ship a well-maintained appearance.

The underwater hull has been professionally treated with a two-component epoxy resin, and the hull with a single-component system. The steel interior is also beautifully painted and well-preserved, ensuring years of carefree use.

A solid sailing yacht, perfect for sailors who enjoy sailing on a reliable and durable vessel.
