PolarWave, the rising name in high-performance sailing hardware, today announced the launch of its newest innovation: the 40mm Ratchet Block—engineered for strength, speed, and simplicity.
The complete PolarWave range is solely distributed throughout the UK by Marine manufacturer & distributor Sea Sure Ltd.
Designed specifically for high-performance dinghies and skiffs—including the 29er, 49er, Nacra classes, ILCA, Waszp, Optimist, 420, and 470. As ropes become thinner and stronger and materials continue to evolve, oversized blocks are increasingly unnecessary. The 40mm size hits the sweet spot for compact strength, offering an ideal balance for modern rigs.
"At PolarWave, we're building the gear we've always wanted to use," said Gašper Strahovnik, founder of PolarWave. "This new ratchet block is just the beginning—expect smart design, top-tier materials, and real performance, without the premium markup."
"It's been a really busy 2 months for us since we took on the distribution of the PolarWave range" says Daniel Henderson, Managing Director at Sea Sure Ltd. "Gašper and his team are adding new products nearly every month for the remainder of the year which is really exciting. We can't wait to get them in stores and on boats throughout the UK dinghy scene."
Engineered for Pure Performance
The PolarWave 40mm Ratchet Block is designed to be as light as physically possible without compromising durability or load-handling ability. Key features include:
- Dual-row ceramic ball bearings for ultra-smooth rotation under load
- Advanced composites and precision-machined components for maximum strength-to-weight ratio
- Customizable side plates available in a range of colours for team or personal flair
What's Next for PolarWave?
