51 years of racing yacht kits. A long history from the very first M-class designs moulded in GRP by the late Tony Abel, and various Marblehead designs and three Ten Raters by Frank Parsons, to the present One Metre/s.

  • A proven design during over a decade of racing, the Spirit Three has many improvements and tweaks, and optimum keel and mast position have been maximised to the full. Features a completely redesigned GRP deck and deck layout (click link/see photo of hull & deck laid on the grass).
    She has all weather capability and can maintain position with her rig when others have had to reduce canvas. When beating she is impressive and she comes into her own when close hauled maintaining a steady course. Hands-off sailing shows her stable nature, and she points very closely. The carefully designed underwater hull shape pays dividends in the way she is quick to respond and handles ably in all conditions.
    A very ‘slippy’ boat, a fellow yachtsman commented! In skilled hands she can be a dozen or so points ahead of the rest of the fleet giving a very convincing win at the end of the days sailing. She will give a very good account when pitched against the broader skiff type of yacht, and we have had many good responses from happy yachtsmen who have impressed others with her sparkling handling and ability to allow the skipper to set a fast course (the quickest way between two points is a straight line!), with the minimum of tacking.
    FEATURES - a finely moulded GRP hull which is trimmed to deck level, carbon fibre fin & rudder and ready–made keel box (incorporating mast box). Rig kit includes Nylet racing scrim sails with 11.1mm aluminium mast & boom tubing. The GRP moulded deck has an after run drop.
    Kit specifications vary, please see options under section 8 in the price list. GRP hulls moulded in white - colours to special order (at extra cost), blue, red, yellow, black, or orange. There is a choice of colour for the sail corners.
    Kits come with a fully illustrated stage by stage colour building booklet (which includes rig building instructions). Our BB3 'How To' booklet is available at extra cost if required.
    The latest Spirit 3 features increased freeboard, new radio layout and a (redesigned) moulded GRP deck with lowered after run. The new deck was introduced late in 2013 and was redesigned in '16.

  • I completed the boat last week and put it into the water yesterday morning, and was delighted with its performance (Mk2b).

  • Just perfect, faultless handling, great to windward, she’s a very fast boat, I’m beating everything else - I’m very pleased.
    Roy, Norfolk
  • As I say in my letter to you, I am very pleased with my Spirit 3. She points so well I can let them all start and still catch up by the windward mark. Many in the club admire it.
    Howard, Norfolk


  • I live on the coast of NSW in Australia. Some time ago I bought No.2751 (the one featured on your site). I am currently racing the boat here in Australia in several IOM fleets. The elliptical rudder works perfectly and the boat is at full potential now, points higher than the TS2 and the Topiko. Neither are faster off the wind.... Thanks for a great boat, I have never felt another IOM that glides to windward like the Three. All your efforts are appreciated here.
