Mainsail
Main RK-1
The sail is manufactured from a cloth combination of 5.52 oz Polykote and Square‑HTP. The optimized luff curve ensures that the sail sets cleanly and can be trimmed easily and precisely. A reduced profile depth in the foot area minimizes rudder pressure and gives the sail a significantly more efficient airflow on the leeward side. A large window arranged parallel to the boom ensures perfect visibility to leeward across all points of sail and at any heel angle. In addition, a spreader window allows continuous control of the jib leech, significantly simplifying precise trimming of the headsail. The RK‑1 is delivered rolled and comes with two different top battens. Up to 8 kn, the short batten is recommended; above that, the full‑length version should be used.
Headsails
Jib L-1
The L‑1 jib has evolved over time into an extremely popular headsail for light to medium winds. Many Soling sailors deliberately choose this model. Its full, rounded entry makes the jib exceptionally forgiving and easy to steer, even under the most demanding conditions. The sail is made from 4.52 oz Polykote, offering an excellent balance of shape stability and durability. In general, the L‑1 is a true all‑round headsail. However, if it is already clear beforehand that a very windy day is expected, we recommend switching to the H‑1.
Jib H-1
The H‑1 jib is cut slightly flatter than the L‑1 and is made from the heavier 6.5 oz Polykote cloth. This material offers an excellent combination of shape stability and durability. The H‑1 is the right headsail for wind strengths of around 18 kts and above.
Spinnaker all purpose GODZILLA
The H‑1 jib is cut slightly flatter than the L‑1 and is made from the heavier 6.5 oz Polykote cloth. This material provides an excellent balance of shape stability and durability. The H‑1 is the appropriate headsail for wind strengths of around 18 kts and above.
Spinnaker LITTLE GODZILLA
The LITTLE GODZILLA is specifically designed for heavy‑weather conditions and is intentionally smaller than a standard spinnaker. Its reduced shoulder width makes it easier for the crew to sail safely and in control on downwind courses in strong winds. Due to its narrower, more compact shape, the LITTLE GODZILLA is also recommended for extreme light‑air regattas: in winds below 3–4 kts, it sets noticeably earlier and more stably than its larger counterpart.
