Worth knowing
Tidemann Boats; cover, cost and conditions
The name in our records, Tidemann Boats, points to Tideman Boats, a Dutch yard based in Hoorn. Tideman builds workboats in HDPE, high density polyethylene, with a fully welded hull, a deep V and spray rails. According to the yard, its boats serve on patrol, as crew tenders, in search and rescue, for pilot work, for surveys and as landing craft. The range spans lines such as RBB, RBC, LC and JB from 7.10 to 11.95 metres. On the pontoon a Tideman stands out by its angular plastic hull without an air tube; the yard sets its RBB boats explicitly against the idea of a rigid inflatable.
Our model records hold a single design under this brand, the RBB 900, filed as a motor yacht of 9.1 metres with build years from 2021 to 2025. The yard quotes 8.90 metres overall and 2.50 metres of beam, and describes the RBB 900 as its midsize centre console workboat for dive support, surveying, patrol and crew transfer. Power comes from up to two 200 hp engines, petrol or diesel, as outboards, water jet or sterndrive. The boat can be trailed and fits inside a 40 ft high cube container. No other lines from the yard appear in our records, and the model does not reach into the most recent build years, so every RBB 900 on our list is a young boat built since 2021.
Polyethylene behaves differently from a glassfibre hull. There is no gelcoat to polish and no osmosis to worry about, but scratches stay visible and the material cannot simply be faired and painted like composite. On a used RBB 900 the welded seams deserve the closest look, especially at the transom, the console mounts and wherever fittings have been added later. Many of these boats come from professional service, so engine hours, the service history of the outboards or jet unit and the state of the wiring tell more than the year on the plate. A trailer in good order is part of the package for anyone who wants to move the boat between waters.
