Performance and design

The Magno is a versatile three-sail boat that is great as either a small family boat or for club racing or teaching. The spacious cockpit with its gnav kicker (an upside down vang) [ clarification needed ] offers roomy and comfortable sailing and is an ideal teaching platform for groups. The boat can be sailed single-handedly due to the zip-reefing system in the mainsail adding yet another layer of versatility.

The Magno is a dinghy that can be used for learning to sail, to club racing. [3] The Magno, a mid-sized dinghy of the topper range, is a good boat for youth training, being stable with plenty of room for two trainees and an instructor. The boat has a Gnav kicker system which gives you more room in the cockpit.

3000 (dinghy) Racing sailing dinghy crewed by two persons with a trapeze for the crew

The 3000 is a racing sailing dinghy crewed by two persons with a trapeze for the crew. Launched in 1996 as the Laser 3000, the 3000 was developed from the Laser 2, using the original Frank Bethwaite-designed planing hull combined with a new designed self-draining deck by Derek Clark. Clark also re-designed the rig, using spars and sails from premium proprietary sources and replacing the symmetric spinnaker of the Laser 2 by a larger asymmetric spinnaker (gennaker). The gennaker is chute-launched and retrieved using a single halyard line, and is set on a retractable bowsprit. Helm balance and handling were improved using a shorter-footed mainsail with two full-width battens giving a larger roach. A mast with conventional spreaders replaced the now-unusual diamond arrangement of the Laser 2.
