- fixed masts.
These fixed masts are rigged in different ways:
- masts on tripods: the spreaders are connected
to the front by a martingale and a jumper
enabling the mast to be made rigid lengthways;
- intermediate shapes: the mast is simply suppor-
ted sideways by the spreaders and a bigger set
of shrouds (not self-standing lengthways, so no
jumpers);
C T M R NS - Pre-adjustment before fitting
The special characteristics of the self-standing rigs on multihulls mean
that the lateral diamond shapes and jumpers are under tension and pre-
adjusted before stepping the mast in order to obtain a rigid structure.

C T M R NS - Special instructions
Catamarans are usually fitted with self-standing systems,
which keep the mast in place with a forestay and two top
stays fastened to chain plates on the hull.
These self-standing masts can be divided into two
groups:
- pivoting masts called teardrop masts or wing masts
(wing masts as found on Formula
28 and F 40);
