SOFT SHACKLE BLOCKS: STRONG BUT PROTECTIVE
Ronstan has released its range of soft attachment blocks that have the highest ratio of dynamic load to sheave diameter of any block in its keelboat block range.
Featuring fully machined aluminium cheeks and sheaves incorporating a full contact, self-lubricating composite bearing running on a polished duplex stainless steel hub, the new blocks are built to last and suit a multitude of demanding applications where high static and dynamic loads are encountered.
Many different iterations of the soft attachments were tested before finalising the specifications of the Dyneema SK99 cord shackle. The soft attachment passing through the hub provides a simple means of attachment and a protective buffer between the block and boat surfaces. It is secured with a titanium ‘dog bone’ that allows it to be easily opened when you need to detach the block. Soft elastomer retaining guides ensure that the block remains aligned within the soft shackle.
With the shackle open, a gentle rotation of the cheeks opens the head of the block so it can be fitted to a standing line. To close the block, rotate back to the closed position. A spring-loaded ball secures the assembly, with no additional external straps or bands required.
There are three different block sizes to take 12 millimetre, 16mm or 19mm rope.
RRP: starting from $475.20.
CATAMARAN CONTROL APP
The American Sailing Association has released an app titled ‘Catamaran challenge’ to create a game that allows players to climb aboard and take control of a cruising catamaran when under engine power.
Operating a twin-engine catamaran is different from operating a single-engine monohull, this app is designed to teach the nuances and to practice skills.
Cruising catamarans have two engines at the stern, each controlled by its own throttle. Changing the throttles in various ways relative to each other affects the movement of your boat allowing you to perform different manoeuvres without using the helm/rudders.
From standing still, it is possible to turn a catamaran within its own ‘footprint’ using just the throttles. It is also possible to steer with the engines when underway, by offsetting the two throttles so that the boat performs a looping turn. The radius of the turn can be controlled
