Sailboat Description

The Lark was designed in 1966 by Michael Jackson, designer of many National 12 and Merlin Rockets, with the first one launched in 1967. The hull made of G.R.P. is 4.065 metres in length, and carries a sail area of 9.75 square metres upwind and a spinnaker of 7.4 square metres. The class currently has a Portsmouth Yardstick of 1073, making it one of the fastest non-trapeze dinghies around!

Please Note: Most of our sail dimensions are based on class rules, designer blueprints, or measurements of sails. These dimensions are intended as starting points only. Sailboats are not all uniform, even from the same designer. We recommend carefully measuring your boat if you are uncertain about dimensions.

All dimensions are intended to be maximum and smaller sails are not wrong.

We've limited our listing to the sails most commonly used, but these are not the only ones appropriate for a given boat.
