Koopmans 50
Description
Superior Dutch-built aluminum Koopmans 50, designed by the renowned Dick Koopmans Sr. A major refit in 2022 and ideally suited for a dream cruise!
Built in 1990, in the water since 1992, purchased in 2015 by last owner at de Valk Yachtbrokers in Hindeloopen. Since then many changes/renovations have been made, including;
- 3 x 250 AH batteries (Gel)
- New Victron battery charger
- New Webasto boiler
- New Raymarine plotter incl. radar and AIS
- Windvane steering
- New genoa, including new furlex system (via Sailselect, Uithoorn)
- New Tikikat dinghy, with Mercury 6 hp
In 2021/2022 "HORIZON" underwent a complete refit at Jachtwerf Brouwershaven, to make her ready for "full liveaboard". The total investment amounted to more than EUR 100,000. In short it came down to the following work;
- The hull was completely done, incl. some new patches welded in, to maintain a full 8 mm all around. At the same time, new TruDesign skin feeders/valves were installed. Completely new painting and additional & new anodes installed.
- Engine water cooler overhaul, full inspection, dual filters installed.
- Teak deck removed, replaced with beautiful and maintenance free Flexiteak
- Keel raise modified with electric hydraulic elevator (was manual hydraulic)
- Windows renewed, new screens inside
- Travelers renewed, all sheets & halyards replaced
- New bimini and splash screens
- Epirb
- Starlink
- Life raft
- Rocna 40 Anchor
In 2023 the ship was registered (Dutch flag), she was branded and microdots were applied to the ship.
Fresh antifouling in 2024 and then also a new anchor winch (Lofrans 1700) was installed, including remote control with counter.
Boat is equipped with many spare parts, even a completely new propeller is on board!
The "HORIZON" is a beautiful and classic "Koopmans" design, and almost in new condition, with many upgrades. Her unique positive transom, modified by the previous owner, gives her much more living space outside. She sails beautifully, no sea is too high, no wind too strong. She was the faithful companion for nearly 10 years and has been the previous owner's home in part for the last three years.
