General Notes
The BB11 is a strict One Design, conceived in
1956 as a high quality. moderately priced yacht, equally suited both
for day cruising and class racing. As a 'thoroughbred' racing boat,
the BB11 is more economical to maintain than the majority of keel
boat classes, and appeals particularly to the dinghy sailor who wants
to continue class racing with more comfort and less expenditure of
effort.
The BB11 is fast and dry, having an easily driven
and particularly seaworthy hull form. Built in buoyancy is incorporated
in the hull to ensure maximum safety under all conditions. the all-up
weight of the BB11 is under three quarters of a ton and can easily
be trailed by road.
The BB11 is designed and built exclusively by
Borge Bringsvaerd, Drobak, Norway. The builder has combined the best
traditions of Norwegian boat building with modern 'flow' production
systems to create a quality product of outstanding value.
There are BB11 Fleets in more than 10 countries,
and several hundred yachts have been built and are racing throughout
the world. The strict One Desing nature of the class is ensured by
rigid and up to date rules controlled by the International BB11 Association,
and the fact that all boats are constructed by one builder ensures
that as far as possible hulls are identical.
The class has been granted National status by the Royal Norwegian
Yacht Club.
