One Design Racing Sails

For dinghies and one design keelboats, Kingston Sail Loft is actively testing, racing with, and further developing sails for 505s, Albacores, and Sharks, and we are interested in working with racers in other regionally active one design classes.

505

The Kingston Sail Loft 505 full triradial spinnakers are available, and are being raced with by 505 sailors in Ontario. The first prototype helped us win the 2024 505 Eastern Canadian Championship. Main and jib prototypes are being tested; we are racing with them and tweaking designs to ensure they provide world-class speed.

An article about the development of the KSL 505 spinnaker is at:

We have taken a number of images of the prototype main and jib from different angles, so we can discuss sail shapes with our designer, and tweak the design for the next main and jib we are building

Kingston Sail Loft stocks 505 top and bottom covers, are working on 505 blade bags (see the Sail and One Design Covers and Accessories page), and will be bringing in mast and boom bags. We also stock 505 slot gaskets or make custom sets to your requirements. We plan to stock a few Selden 505 Alto and Cumulus masts and carbon booms, as well as some spar parts such as goosenecks and heel fittings.

Albacore

Kingston Sail Loft has been working on our Albacore sails, first designing on the computer, then building prototypes, loaning them to Albacore sailors, and racing with them ourselves.

We have Albacore flat top covers and are working on an over-boom top cover. We have a few Albacore slot gaskets in stock and make more as required. Kingston Sail Loft is a Selden dealer and is working to bring in Selden Cumulus and Alto masts and 2633 booms for Albacores.

Shark

Kingston Sail Loft has Shark mainsails, and genoas based on the well-respected John Clark Shark sail designs available. We also have jibs and spinnakers available. Bob is also developing some alternative Shark designs in-house, for in-house building.

We are considering building Shark rudder bags.

We may stock Selden 2633 booms for Sharks if there is interest from the Shark fleet.
