Mainsheet System, CP-18 Stainless Steel Blocks

Part #: BI9051
$232.02 $197.22
Mainsheet. system for the Capri 18. System includes stainless steel blocks which are impervious to UV degradation and our special "fuzzy" line which is easier on the hand when playing the mainsheet. The blocks carry a 10 year manufacturer's warranty.
Unique to our stainless steel mainsheet tackle is a provision to adjust the angle of the cam cleat on the lower fiddle block. Catalina Direct's custom made block provides for adjustment of the platform on which the cleat is mounted. Without this adjustment, the angle of the mainsheet will be incorrect. If the cleat is too low, you won't be able to easily un-cleat the line in an emergency. If the cleat is angled too high, you will not be able to cleat the line when necessary.

With our custom made block, a suitable angle can be achieved to make it easy to cleat and, for increased safety, release the mainsheet at a moments notice. The mechanical advantage of the mainsheet can also be configured to give either a 3:1 ratio (for faster sheeting adjustments) or a 4:1 ratio (for sheeting in heavier wind areas). See "More images" below for a complete understanding of these features.

Stainless steel construction with full stainless cheeks won't weaken and break due to exposure to sunlight. The bearings are always contained by the stainless and wont drop out over time.

To prevent the line from twisting or binding when used in a cascade or mainsheet system the blocks in this kit is supplied with a feature to lock the rotation of the shackle that is on top of the body of the block. With the use of an Allen wrench, tighten the set screw to lock the shackle in position. When used as a swiveling block, ensure the set screw is not tightened and the swiveling shackle can self-align to find the fairest lead.

1) The length of this item is based on the original factory specifications. However, the previous owner, like Captain Jack Sparrow, may have had an entirely different idea about how to rig a boat! Please confirm this is the correct length for your particular boat. We cut it from a long length and can't splice it back together again. Your order cannot be canceled, returned or exchanged, but, like Jack, you may have a different idea of what you can use it for!

2) The savings is the discount we offer when you purchase the mainsheet system as a package when compared to purchasing line by the foot and the blocks individually.
