I. Introduction
Mast, boom and rigging are an important part of your yacht. It is the reason why you should
tune the rig in a proper way to obtain the best performance and reliability.
Before stepping and using your rig, you must read all the following information.
II. Stepping
When a new mast is being rigged for the first time, you must determine its center of gravity.
To do this, the mast must be laid like a seesaw. In general, the center of gravity is found at about 60%
of its height. This mark will be used to place the lifting strop.
Check that the navigation light, deck light and wind instrument on the mast are working. A
12V or 24V battery must be available for this.
During stepping the windex and wind instruments might be damaged, we recommend to fit
them after stepping.
Check that all split pins are open. You can use tape or silicone to protect the sails.
The spreaders with uniball must be secured at correct angle with Kevlar lines
Before lifting the mast with the crane, fasten the standing rigging to mast step in order to
keep it from trailing around.
Kevlar cables need to be pre stretch during 10 hours at 10% of the breaking load before
installation. This will help considerably when stepping.
