RONSTAN Multihull Blocks - Overview |
Lightweight. Kilogram for kilogram of working load,
Ronstan Series 55 Ball Bearing Orbit Blocks™ are
the world’s lightest. The unique orbital design allows the
bearing to only be in the active areas of the floating sheave.
This minimises the mass of the inactive return race and hub.
Weight and bulk are further reduced in the different block configurations.
The ball bearing single and becket block has a through-sheave
becket arrangement. The result? The lowest weight possible.
Multi-sheave blocks have only single intermediate cheeks and
an ultra-light and efficient head arrangement. This gives a 30%
weight saving advantage over the nearest competitor. Other brands
just link together their single blocks. This results in unnecessary
double cheeks between each sheave, held together by a heavy steel
channel across the top of the block. Pair this assortment of blocks
to produce up to a 9:1 mainsheet system for use on catamarans
to 5.5 (18ft).
