Trimaran
A Trimaran is one, which consists of a main hull and two smaller
outrigger hulls attached to the main hull with lateral struts. The
design and names for the Trimaran components are derived from the
original proa constructed by native Pacific Islanders.
Trimarans have a number of advantages over comparable
monohulls. Given two boats of the same length, the trimaran has
a shallower draft, a wider beam, less hull area, and is able to
fly more sail area. In addition, because of the wide beam, trimarans
do not need the weighted keel required in monohulls. Thus, the trimaran
offers much better straight-line performance than a monohull is
able to sail in shallower water, and maintains its stability in
stronger winds
trimarans are much safer than a monohull as the
lack of a heavy keel, combined with the two (usually sealed) amas
makes for a nearly unsinkable boat. Because of their stability and
safety, trimarans such as the Challenger class have become popular
with sailors who have restricted mobility.
Potential buyers of trimarans should look for one
that is designed with multiple sealed partitions, controls that
all run to the cockpit, a collision bulkhead, partial or full cockpit
coverings or windshields, and drain holes in the cockpit that can
adequately drain the cockpit quickly, among other things.
