Measuring For
Your New PC Mainsail
(Choose
luff & foot length, check corresponding leech length.)
| 1)
Determine the range of your outhaul adjustment, and mark for
both minimum and maximum foot length. |
|
| 2) From the aft face
of the mast, (not the tack shackle) measure to the marks you
made in step 1, and record both minimum and maximum foot length. |
|
| 3) From our selection
of sails, choose the foot length which best fits within the
range determined in step 1, and mark the location. Record
the foot length you select, and compare to your minimum and
maximum dimensions for accuracy. |
|
| 4) Attach
the measuring tape to your main halyard and hoist the tape all
the way to the top of your mast. Record the measurement
between this position, and the bearing surface of your tack
shackle. This is your absolute maximum luff length. |
|
| 5) From our selection
of sails, choose a luff length which is shorter than your
maximum luff length by at least 1%. Record the luff length
you select, and compare to your max luff dimension for accuracy. |
|
| 6) Lower your main
halyard until the dimension you selected in step 5 is even with
your tack shackle, and cleat the main halyard in its normal
position. |
|
| 7) At this point, you
have determined the appropriate luff and foot length, and need
to make sure that the boom will clear any dodger, bimini, or
boom gallows on your boat. From our selection of sails,
determine the leech length that corresponds to the luff and foot
length of the sail you have selected. With the measuring
tape still hoisted to the luff dimension of your new main,
determine your boom position by matching the leech
length of your new main, to the mark you made for your foot
length in step 3. With the boom set in this position,
check to ensure that there is adequate clearance under the boom.
Remember, the sail will stretch a bit when in use. |
|
8) Select the appropriate luff
slides from our selection page.
9) Repeat this entire process
to ensure accuracy.
10) Place an order for your
new PC main. Remember to order the appropriate luff slides, they are
included in the price of the main.
