Hallberg-Rassy 412 is the first boat to test the new FatFurl furling mainsail from Elvstrøm. FatFurl combines a proper headboard of 33 cm at the top with a generous positive leech curve.
Seemingly too-good-to-be-true, but still true. For the first time ever there is now a furling mainsail that visually and performance-wise fully matches a traditional folding mainsail with long battens.
The sail has been developed in co-operation between Hallberg-Rassy and Elvstrøm and will be offered in the OEM market (market for new boats) only through Hallberg-Rassy for one year.
The headboard contains a secret solution making it stiff enough for sailing, yet soft enough to be furled.
Hallberg-Rassy offers four different levels of furling mainsails: No battens with a negatvie leech curve, EMS - Full vertical battens with a straight leech, EMS Max - Full vertical battens with extra intermittent battens and a positive leech curve, and now also the FatFurl with the headboard and extra positive leech curve for maximum performance.
Ease-of-handling is always a trade off with performance: the no batten mainsail is the most forgiving as concerns handling, but lowest performer. FatFurl provides the best performance, but requires more precision when furling and unfurling.
