Ronstan releases 30mm lashing block for high-load applications

Ronstan has released a 30mm lashing block specifically designed for modern high-performance foiling, skiff and multihull classes. It’s said to suit any applications where high loads are experienced.

World Moth Champion, Paul Goodison, uses it in his vang system because it handles the high loads with low friction, giving him fingertip control.

Typical applications include high load vang purchase systems on Moth and Lasers, halyards on 16 and 18ft skiffs, cunninghams, outhauls, and backstay purchase systems.

The RF35109HL has a maximum line size of 8mm and is rated to 550kgs (1210lbs) Maximum Working Load and 1650kgs (3630lbs) Breaking Load. The Breaking Load is dependent on the strength of the lashing through the central hub. The hub can also double as a becket take off point.

At just 42 grams (1.5oz), its impressive strength-to-weight ratio is said to be a result of clever design and the selection of the right materials, such as glass fibre reinforced nylon cheeks, a high-grade stainless-steel sheave, ball race and balls.
