Mast Assembly:
1. Each mast is packaged separately.
2. Main mast has the long bottom or heavy section and the short top or light section.
3. The mizzen mast has the shortest heavy section and the longest light section.
4. The main has the longest boom and the mizzen the shortest.
5. The top section simply fits into the bottom section. ( no fasteners) However, it is good to tape the
two sections together with a strong tape to eliminate movement between the two.
6. Both masts will be the same length when put together.
7. The booms are held into the gooseneck with a quick release pin. Some older models rely on
pressure from the outhaul and vangs.
Attachment of booms:
1. Attachment begins ideally with sails furled around the masts. To furl them, simply hold tension
on the clew of the sail and turn the mast. Another hand or a gentle breeze is helpful here. We
suggest that you do not try this in a heavy breeze the first time.
2. Position the sail slide near the center of the boom. (This is so the boom will be balanced after
attachment.)
3. Fasten the clew of the sail to the boom sail slide with the snap shackle.
4. You are then ready to release the furled sail and roll it out by turning the mast. Let the sail
support the boom, and slide the outhaul outward as more sail is unfurled, until it is all out or
you have as much out as desired for the wind conditions. Caution: Keep the sail flat with
tension against the clew with the outhaul line or boom while you are unfurling the sail. If you
don't, it can have a violent whipping action in high winds and can cause serious injury when
out of control. When done correctly, there is no strain or violent motion. Practice!
5. Insert the gooseneck pin into the hole in the boom end. (This step not necessary on newer
reefing goosenecks, as their booms always stay attached while unfurling or furling the sail.)
6. Attach the sheet line to the boom bail at aft end of boom.
NOTE: This procedure is for both main and mizzen. You will also note that this system allows you to
reef very easily by releasing the tension on the outhaul and removing the vang at the mast. You may
then release the slide lock on the gooseneck and roll up as much sail as you desire. Reset the slide
lock, tighten the outhaul and then snap on the vang. Easy to do, but practice makes perfect.
