This stainless steel series, with a traditional design, is conceived especially for classic boats.

The line includes 6 different sizes with diameters from 65 to 180 mm and Safe Working Load up to 9000 kg. Perfectly polished AISI 316 stainless steel cheekplates and accessories, fully rounded corners for greater manageability, nuts and bolts replaced by pins and recessed screws to eliminate any protruding parts. The composite fibre sheave. The resin (aluminium on larger mod) sheave runs on the main Composite Fibre bearing and on a ground s.steel hub: low friction highloads – no lubricant required. The self-captive side ball bearing reduces the friction and makes disassembling, cleaning and maintenance very easy.

Solution designed to solve the connection of a sheave to the furling mainsail clew efficiently. The block is contained within the size of the sail, thus allowing a larger surface of the mainsail to be used. The choice of materials guarantees the least weight as well as a very good mechanical resistance to the environment. Particular care has been taken over the ease of connection which is obtained by normal “webbing”. This ensures moreover a very good distribution of the load on the sail.
