History and Design

40 Years of NS14 Hull Design 

Rohan Nosworthy was kind enough to contribute the following list and several pictures as a starting point for compiling the history of design innovations in this very innovative class. The comments made regarding the performance of the various hulls are comments made by sailors who have rated the hulls on the NS14 hull poll page. They do not necessarily reflect my opinions, but those of a variety of sailors of varying preferences.

Brief History of key design innovations...

Aero - 1221 6/10/79

Flight 17 - 1222 06/11/79 (first boat with 'measurement bumps')

Gift Horse - 1240 09/12/79 (David Stabback)

Flight 18 - 1247 10/03/80 (initially only given 6 week provisional rego, passed by sub-committee meeting 27/12/79)

Gift Horsersorous - 1313 18/11/80 (Tubular hiking racks - David Stabback)

Aero 3 - 1365 5/10/81
"This boat romps along providing there are no waves. It hates waves! Aggressive colour scheme is pretty menacing. Quick in a drifter with light crew, quick in above 15 knots with moderate weight. Lacks a little light air finesse."

Fresh Zuchini - 1382 3/12/81 (Michael Bochner)

Aero 4 - 1447 20/11/82
"Flies in heavy weather with two lumps on the rail"

Smouldering Ferrets (Aero 5?) - 1474 18/9/83 (Gavin Jones)

Fast Bazoomies - 1486 13/11/83 (Michael Bochner)

Aero 6 - 1548 21/03/85
"Goes like a train in survival conditions.This is the most stable ns14 hull in heavy weather. No reinforcing at the back of the boardcase can be a problem. Massive conecaves in the bow sections running a long way back make for a narrow waterline and extrememly fast in the right conditions ie short chop. Loves waves & light wind, Loves light crew. Quick all round the course. Matches 7s & 8s upwind in all conditions. Have a feeling the 8s are quicker downwind at times. Sixes suited more the extreme conditions either end of the scale. More stable is the definitive factor. In Heavy runs, crash jybes, windward work a well set up 6 will match any 7 and 8 around the bouys"
"Nice easy boat to sail. Was tailored to a lighter crew weight than most new designs. A small boat, performed well in most conditions."

Aero 7 - 1653 21/11/87
"One of the most stable NS hulls around. Carried weight well. Easy to sail, still performs well in planing conditions. High wetted area is the only drawback in light airs and for top speed."

Aero 8 - 1725 17/10/91
"Feels really similar to the Aero 7, but planes slightly higher out of the water due to more buoyancy along the flattened center of the hull."

Outlaw - 1756 10/09/92 (Barry Drurey)

First Carbon Tipped mast 12/12/93 (Peter Goss)

Out to Lunch - 1772 Sep 94 (Phil Stevenson)

Take 5 - 1785 March 95 (Stuart Friezer)

Aero 9 - 1787 03/04/95
"First of the 'new generation' of hulls, with the buoyancy very centralised and narrower water lines. Very efficient, fantastic light air boat, still capable of winning races. Can perform well in any conditions in the right hands, but likes a skipper with 'finesse' on the tiller. Carries weight well."

Max 5 - 1819 15/03/96 (Peter Goss)

Flight 24 - 1824 March 96
"Very stable, great performing hull. Planes easily, is very forgiving and carries weight the best out of any of the new hulls. The Cadillac of NS14s."

Tequila 1 - 1834 20/07/96 (Mamo)

Tequila 96 - 1836 27/08/96 (Stuart Friezer)
"Performance potential equal to any of the designs. But it needs very careful trimming and an agile crew (preferably lighter end of weight range) to extract the best. In stronger winds and flat water, arguably one of the quickest hulls. Acceleration is fantastic. Can be a bit gripey in very choppy conditions as it tends to want to steer itself! Tame this quality and you are rewarded with one of the best rides around."

WOW Cuba Libre (Force 5) - 1855 15/03/97 (Alan Cawardine; Julian Plante sailed this to win the Mooloolaba Nationals 97/98 season)

Battlestar (Force 5 mk2 ?) - 1885 30/11/97
"Excellent for heavy crews."

Fireworks (Force 5 mk2 ?) - 1891 30/11/97 (Alan Cawardine; Dished deck.)

Aero 10 - 1893 22/03/98
"Similar forward lines to the Aero 9, but with straighter lines aft and flattened under the centrecase and maststep. Personally, I believe it to be the best allround, easiest to sail NS14 ever designed, with performance to match any hull.Can carry a very wide range of weight from 114kg up to 150+kg. Anyone moving from an older hull into the Aero 10 improves."

Tequila 99 - 1912 10/08/98
"Solved the 'gripeyness' and improved on the weight carrying ability of the Tequila 96 by the fattening up of the center sections of the hull. When sailed well, can compete with any of the designs, but must be kept properly trimmed at all times, particularly to get onto the plane in marginal conditions. Planes very quickly with the bow right out to the centrecase and the crew stacked on the back corner. Upwind in strong breezes, arguably still the quickest hull around."
"As for someone who jumped out of a earlier design into one, a very nice all round boat only one down point very hard to lift with no real gunnals to lift near stern."

Skyrocket (Force 5 mk?) - 1930 27/04/99 (Force 5 with hollow below chine)

Aero 11a - 1937 22/11/99, Time Rocker
"Very narrow on the waterline but with a slightly fuller entry than the Tequila 99. Has good acceleration and great speed in flat water. In marginal planing conditions, it will plane earlier than most of the other designs making it very good on broad reaches."
"The fastest current hull - the fastest for ever more?"

Space Invader (Force 5; Peter Goss) - 1941 13/12/99 Complies with 2000 rules. Great looking hull.

Aero 11b - 1942 01/03/2000 - Michael Nash designed. Initially built by Kulmar Boatbuilders. 
Still a competitive design, particularly in light airs and upwind. Very easy and comfortable to sail, only loses out in broad reaching planing ability. 

Pumpkin Eater - 1948 5/4/2000 - Stuart Friezer design. Tequila 99 built by Sunburst Marine. Modded by Peter V. 
The last of the boats with hollows under the measurement point. Very successful boat, modified to improve the light air/broad reaching performance. The changes also improved the square running speed and in Peter's hands was extremely quick under pole. 

Tequila 2000 - 1950 07/12/2000 - Stuart Friezer design, Built by Sunburst Marine . 
Designed to the new 'no-hollows' rule, this design won the 2001 NSW State titles in the hands of Jamie Roberts, beating all the 'bumped' boats. Upwind in flat water, was very quick when accurately trimmed fore-aft, but struggled with heavy crews when reaching. 

Komodo - 1964 25/03/2001 - T2000 modded by Rohan Nosworthy/Peter V. 
Delivered by Sunburst Marine initially with a sacrificial outer skin, this boat had its rocker line and rear chines/bottom modified to try and alleviate the perceived T2000's shortcomings and to replicate the powerful transom of the Tequila 99s. The boat proved to be very quick reaching, and carried weight well, but was harder on the crew to keep it in its sweet spot. When you got it right, it was very quick. 

Smashing Pumpkin (1978) 13/11/2002 - Fever design by Stuart Friezer, built by Peter V. 
Male jig built hull, the Fever design was the precursor to the production Tiger, and one of those built (1979) was used as the plug for the current Tiger production hull. 
By all accounts, this design 'smoothed' all the gripes of the previous Friezer designs, and became an easier to sail boat that lost none of the all-round raw speed gains made in each of the previous designs. 

Tiger - 1981 23/03/2003 - Built by Mark Thorpe Boatbuilding. Designed by Stuart Friezer. 
One of the most successful designs ever, there have now been over 30 built and they have won almost every National and State Titles since it's inception. Highly refined, easy to sail, and very rewarding was pushed hard, it is truly a sailors boat and almost everyone who has stepped into one from an older design has improved dramatically. Supports weight well (up to 140kg), but needs to be sailed very flat and trimmed aggressively fore-aft to extract it's true potential. 

Moondance - 2000 24/12/2007 - Home built by many. 
Very similar to the Tiger, but with flatter panels and harder chines, the Moondance was designed by Stuart Friezer as a way for home builders to be able to build a good-performing, strong boat. 
One of the strengths of the NS14 has been the ability to build a boat yourself, and this had been lost from the class for a long time. The female moulds for the hull and deck are available for use upon request, and 15 boats have now been produced - both using resin infusion techniques and traditional vacuum bagging methods. 
Peter V has won the Nationals the past 2 years with this design - in boats built by resin infusion in his garage at home. 

Aero 12 - 2015 20/12/2009 - Hull Design by Michael Nash. Deck design and built by Dave Dillon. 
Seven boats of this design have been built in a limited production run out of Dillon Boatbuilding in Taree. The Aero 12 is a refinement of the Aero 11b, with changes made to mainly improve the planing performance. The Aero 12 carries weight very well, as can be seen by Adam Cause's results sailing in the heavyweight division (145kg+) in the last Canberra Nationals. Performs very well upwind. Future availability of new boats is currently uncertain... 

Mystic Moondance - 2047 10/11/2012 - Built using the Moondance mould, modifications by Rohan Nosworthy/Mark Holt. 
3 boats have been built, dual registered as NS/MGs. Changes to the front and rear sections, to allow the back of the boat to be pushed harder, and obtain and maintain a higher top-end speed downwind.  A side benefit of the extra volume, should allow heavier crews to perform better in light airs.

Midnight - 2070 2018 - Hull Design Stuart Friezer, built by Bernard Parker
16 NS/MGs have been built. Progressing from the Tiger the biggest changes are flatter planning sections to allow it to plane up wind earlier and jump onto the plane quicker; move the forestay, mast, and centreboard case back by 100mm to change balance; more buoyancy under the mast area; cockpit redesign to stop boat carrying water in light air; built-in mast step that can accommodate MG14 Spin pole; one piece Deck that can be removed from mould (no joining afterward); and all forestay/spinnaker pole pieces are part of the hull build so assembly is easy.
