The designs


National 12 designs go back to the 1936 and there have been substantial developments in hull shape, construction methods, materials and rig since then. Typically there has been a paradigm shift every decade or so. There are four main classifications in the fleet; double-bottomed, foilers, admiral's cuppers and vintage. There are often prizes for these different classifications at the major events.Within these classifications there are hundreds of designs. Some of these were particularly popular and are described on the list below. You can read about all the N12 designs on the boat database.

Year Design Picture Summary . . . Price guide (£=400-1k, ££=1k-2k, £££=2k-4k, ££££ 4k+)
Light weight = Good for light weights, Heavy weights= Good for heavier crews
2012 Hijack Hijack Designed by Dave Hollom and manufactured by Composite Craft, launched mid 2012 and has showed good pace particularly in strong winds. The design won the Burton Cup in 2018
££££
2009 Dead Cat Bounce Dead Cat Bounce Another innovative design from Jo Richards which has proven itself at Burton week since 2009. Jo designed the boat around the rudder foil. It has low free-board and a pronounced bustle in the rear sections of the hull. This would normally generate a large stern wave but with the foil this produces a pack that has low wetted surface area and a small stern wave.
££££
2008 Paradigm2 Paradigm2 A development of the experimental Paradigm design by Gavin Willis. The Paradigm 2 has a more conventional rig but still sports a winged rudder and higher side decks than standard. Several production runs were made of this design.
£££
Heavy weights
2003 Paradigm Paradigm An experimental design from Gavin Willis. The original included flaps in the bow a aero-foiled foredeck for extra lift. It also sports a winged rudder for better control.
Heavy weights
2003 Paradox N12 Bim Daser's third in the series which started with the Feeling Foolish. The Paradox has maximum width decks from the shrouds to the transom providing the helm and crew with maximum leverage when hiking giving it more power in a blow. The rounded hull also means the Paradox is easily driven in light airs if care is taken to avoid dunking the wider decks
£££
2001 Numinous
N12 Developed from the Feeling Foolish by Bim Daser. The Numinous is a rounded very low drag design which is great in light winds and surprisingly good in restricted waters. Performance in windy conditions is equal to the Feeling Foolish.
£££

Light weight
2000 Annie Apple N12 Annie Apple has been designed to minimise drag (surface and wave making) and maximise righting moment and lift. Designed by Dave Greening & built by Nigel Waller.
£££
1998 Big Issue N12 Designed by Phil Morrison with high speed off wind performance in mind. The hull design was influenced by Phil's design work on International 14s.
£££
1995 Feeling Foolish
N12 Designed in 1995, this design is an excellent all-rounder. The Feeling Foolish has a rounded hull with a small chine which makes it easily driven in light winds whilst maintaining great pace on open waters and has outstanding down wind performance in a blow. Bim describes the Feeling Foolish to Yachts & Yachting
££
1993 Wild Front Ear
N12 A subtle "Vee" hull provides increased speed on the transition to planing, it surfs well.

££
1991 Freak out
N12 A modified Crusader with better planing performance, and a drop-dead-gorgeous figure! The freak out has a low wetted surface area hull so is easily driven in light winds. They also have a wide deck giving them power in a blow.

££ Light weight
1989 Designer soap dish N12 The first "almost self draining" N12
£
1987 Radical posture
  Blistering speed in a blow, however its flat rocker and full sections make it hard to sail in light winds
£
1987 Design 8
N12 A modified Crusader made in "off-the-shelf" GRP. It is a good well behaved all-rounder and performs successfully in all conditions An excellent boat to get started in the class.
£
1987 Final Chapter
N12 The Chapter has been campaigned by heavier crews with great success. If you and your crew are over 22 stone this could be the boat for you. In recent years light crews have had good results showing the design isn't just for heavy weights. Also a number of boats have had rudder foils retro-fitted and have proven to be highly competitive.
££ Heavy weights
1981 Crusader
N12 A fine all rounder with good sea performance. It has a powerful hull with less rocker than its contemporaries.
£
1981 Baggy Trousers
N12 A wide, powerful hull which is at its best on the sea in a breeze. This is very fast on the plane and is not for the faint hearted!
£ Light weight
1981 Baggy II
  A Baggy Trousers development with even more speed! If that is possible!
£ Light weight
1980 Rough Diamond
N12 Good all rounder with a round bilge giving it an edge in light airs. Now superseded by the Trouble Shooter.
£
1980 Tigress
N12 Round bilged Tiger, another good all rounder.
£
1979 Punkarella N12 Punkarella was a one-off boat, which was ahead of its time and paved the way for the wide, fast designs
1979 Street Legal
  The Street Legal has a very wide hull which is a bit stick and so  difficult to make go in light winds, but watch it go in a force 4.
£ Light weight
1978 Tiger
N12 The Tiger is a modified Cheshire Cat with flatter sections making it faster on the sea. In the right hands they are still seen at the front of the fleet.
£
1977 Scooter
  A "beamy" four plank development that was produced in GRP and showed lots of promise in the late 70s
£
1977 Bouncer
N12 Bouncer was a pioneering wide and flat design, still very fast on open water.
£
1976 Pipedream
N12 You will not be out-pointed with this one. An easily driven hull with very fine bows makes it excellent inland and to windward.
£
1975 Wind-Fall
  This has an inverted garboard which reduces the wetted area and makes it fast in sub-planing conditions £
1973 Cheshire Cat
N12 The most successful design of the 1970s. Now superseded on the sea, but still a good all round inland boat for restricted waters.
£
1972 Paper Dart
N12 Indestructible GRP development of the China Doll (1967) and Whisper (1970). Many are still doing well in the hands of club racers.
