MAINSHEET SYSTEMS

These systems are particularly suitable for the mainsheet control.

They are all fitted with:

All sheaves are made of HRM resin with 2 races of ball bearings for lines up to 12 mm.

On these systems the double and triple 65mm blocks are supplied with a special stronger swivelling head: mod. 900.657 for the double and mod. 900.658 for the triple.

-	2 blocks (sheaves Ø = 65 mm) to connect to the boom;
-	1 main block (sheave Ø = 75 mm) with “camcleat” and swivel coupling to the main car;
-	finally, a double or triple swivelling block, with 65 mm diameter sheave is connected to the main block.

For boats up to 40'

TWO SPEED MAINSHEET TACKLE:
4/8 AND 16/8

The particular configuration adopted permits the use of large diameter sheaves which improve performance of the system; it also ensures maximum block orientation capabilities and therefore the possibility to operate on both sides of the boat.
Furthermore, this reduces the necessary sheet length.

The two speeds are controlled by means of two independent lines.

Main sheaves (Ø = 65 mm) are made of HRM resin and fitted with a double ball bearing.
For rope Ø = 12 mm.
