International Moth

International Moth Boat Sales ⏬⏬

The International Moth is a high-performance, single-handed dinghy designed for experienced and adventurous sailors seeking cutting-edge speed and agility. It is not recommended for beginners due to its highly technical and physically demanding nature. The Moth attracts competitive sailors who enjoy the challenge of mastering its foiling technology and pushing the boundaries of small boat performance. It is particularly popular among those who have a strong background in competitive sailing and are looking to take their skills to the next level.

The International Moth is designed for one person. Its lightweight, carbon-fibre construction and advanced foiling capabilities allow a solo sailor to achieve remarkable speeds and manoeuvrability. The boat's design requires a high level of skill and physical fitness to handle effectively, especially in windy conditions where the foils lift the hull out of the water, reducing drag and significantly increasing speed.

Performance & Sailing Experience

The Portsmouth Yardstick number for the International Moth is approximately 570, reflecting its status as one of the fastest dinghies on the water. This exceptionally low PY number indicates its superior speed and performance compared to most other dinghies, both in displacement and foiling modes.

Popularity in the UK

The International Moth is popular in several sailing clubs across the UK, particularly those with strong racing programs and facilities that support high-performance dinghy sailing. Notable hotspots include the south coast, particularly around the Solent and Weymouth, where conditions are ideal for foiling. Inland venues with consistent wind conditions also host active Moth fleets. Events like the UK Moth Nationals and the Foiling Week in various locations around the UK attract a dedicated following of Moth sailors.

International Moth Alternatives


The Waszp is a close alternative to the International Moth, offering similar foiling performance but with a more accessible and affordable design. It is aimed at sailors who want to experience foiling without the steep learning curve and higher costs associated with the Moth. The Waszp has a Portsmouth Yardstick number of approximately 850, making it faster than most traditional dinghies but not quite as quick as the Moth. It is popular in many of the same clubs and events, providing a stepping stone for sailors aspiring to sail Moths.


The RS600FF is another high-performance foiling dinghy that offers an exciting alternative to the International Moth. Based on the RS600 hull, the FF variant includes foils that allow it to achieve similar speeds and performance characteristics. With a Portsmouth Yardstick number around 750, it provides a fast and exhilarating sailing experience. The RS600FF is popular among sailors who want the thrill of foiling but prefer a design that is slightly more forgiving than the Moth.


The Skeeta is a modern foiling dinghy for solo sailors, designed to be user-friendly and versatile, with a retractable foiling system for both foiling and displacement modes. Compared to the International Moth, the Skeeta is more accessible and stable, ideal for intermediate sailors and those new to foiling. The Moth, with a Portsmouth Yardstick (PY) number around 570, is faster and more technical, suited for experienced sailors seeking top-tier performance. The Skeeta is gaining popularity in the UK for its ease of use, while the Moth remains a favourite among elite racers.


The International Moth is a high-performance, single-handed dinghy designed for experienced sailors seeking advanced foiling technology and speed, with a Portsmouth Yardstick number of around 570.
