Worth knowing
Bosgraaf; cover, cost and conditions
The Bosgraaf name points to Peter Bosgraaf, a yacht designer from Medemblik on the IJsselmeer whose office works as Bosgraaf Yacht Design; his designs also include trimarans such as the Trimax 1050 and 1080. In our records the name stands only for sailing multihulls. The names explain the boats: Tri marks the trimarans, Trailertri and Trailerkat the models laid out for road transport, suffixes such as C, Racer or C/R the versions, and the number sits close to the length in feet.
Our records hold seven Bosgraaf models, all sailing multihulls: the Starter 800 Trailerkat, the Tri 26 C Trailertri, the Tri 26 Racer, the Tri 30 C Trailertri and the Tri 33 C/R, Tri 48 C/R and Tri 70 C/R. All are recorded from 1996; five run until 2005, the Tri 33 and Tri 48 until 2002. Lengths step up from 8 metres for the Starter 800 and both Tri 26 versions to 9 metres for the Tri 30 C, 10 metres for the Tri 33, 14.8 metres for the Tri 48 and 21 metres for the Tri 70 C/R.
The trailer models up to nine metres let owners reach new sailing areas by road and keep the boat at home over winter. The big Tri 48 and Tri 70 need a wide berth or a mooring, since a trimaran's beam rules out many standard marina slots. With every boat now at least twenty years old, crossbeams, connections and rigging deserve a careful look before each season.

and the berth belongs in the application: double width often means a mooring rather than a marina.
