2.1.5. Lowering the mast

Step 1.
Lowering the mast the first time it is best to be with three persons. We will
tell you how to do it with two people.
Make sure the mast is on level ground or if that's not possible make sure the
bow is downhill to make it easier to lower the mast.
Step 2.
Make sure the staymasters are as long as possible (setting 10). The mast
must be rotated to 90 degrees to be able to be lowered. Not rotating the
mast may put excessive load on the mast pin/ball which may cause damage
to any of these items or cause the mast to come off when lowering causing
potential damage or injury. CAUTION: Check for overhead wires and be
sure the area behind the boat is clear of people! A mast which co-
mes in contact with electrical power lines can cause serious injury
or death.
Step 3.
One person stands on the trampoline and pushes the mast forward, while
holding the mast at right angle with the front beam. The other person takes
out the clevis pin from the forestay adjuster, while holding a trapeze wire to
support the person holding the mast. He then places one foot on the mast
base to prevent the mast base from coming off the mast ball.
Step 4.
The person who is holding the mast walks backwards while lowering the
mast. The person with the trapeze wire should pull on the trapeze wire to
make lowering the mast easier. Make sure the mast base does not come off
the mast ball, by placing your foot on the mast base!
CAUTION: Check for overhead wires and be sure the area behind the boat is clear of people! A mast which comes in contact with elec-
trical power lines can cause serious injury or death.
Step 4
Put your foot on the mast base!
