The San Diego models have been developed
by two-time J/24 World Champion Vince Brun and his team in San Diego.
The moderate, consistent winds and year round sailing opportunities
in San Diego are ideal for sail testing and these designs are the
result of countless hours of two boat testing. Utilizing a simple
4-setting tuning system the San Diego designs are true All Purpose
designs. These sails will take you from the lightest drifter to
25+ knots of wind.
The San Diego designs utilize slightly more mast pre-bend than
the Newport designs. This makes the mast set up slightly softer
and hence produces a very forgiving setup. While having the the
right tune is still important with the San Diego designs we've
found this set up to be especially versatile if you are caught
with the wrong tuning for a particular breeze.

MAINSAIL

#1 2009 South Americans!
-
The AP-2 is a flatter sail and this makes it a much easier
sail to trim and set up. A flatter sail can be trimmed tighter
before it is oversheeted and this makes the AP-2 easier to
use for sailors of all experience levels.
-
The other thing a somewhat flatter main does for the J/24
is it makes the whole trimming of the sails more automatic.
As we trim the main in the leech of the main gets tighter,
this in turn pulls the top of the mast back slightly which
tightens the headstay and flattens the genoa. The two sails
are trimmed in synch with each other and the flatter main
makes this possible.
-
The AP-2 comes complete with everything you need,
vision and spreader windows, sail numbers, battens, insignia
and roll bag.

"We won the South American J-24 Championship, using San Diego sails,
and a Newport Spinnaker. We beat the 3 time world champion, Brazilian
Mauricio Santa Cruz, who was the local favorite!!!" -- Alejandro Rossi

SAN
DIEGO GP-7 PENTEX GENOA
-
The 3DL Kevlar patches are standard on our very successful GP-7 Genoa.. Learn more about North's exclusive 3DL genoa patches.
-
The GP-7 Pentex Genoa features all the characteristics of our very
successful GP-5 Genoa with a little bit more shape on the
top to improve light-medium air proformance.
-
Inch for inch the GP-7 Genoa incorporates more low stretch
Pentex fiber than any other J/24 genoa on the market today.
We have worked hard to maximize the amount of fiber in this
sail in order to make it the longest lasting genoa you can
buy. More fiber is what makes a sail last longer!
-
After experimenting with many types of hanks on the market, we've opted for bronze hanks on the luff for the best durability and speed of hoist/drop. Our hanks are now unevenly spaced along the luff (further apart at top and bottom of the sail) to provide maximum support in the middle luff of the sail and reduce friction in the top of the sail so it drops faster.
-
The GP-7 comes complete with window,
lightweight nylon hanks on the luff, leech line, foot line,
sail numbers and roll bag.

SAN DIEGO GP-7TW TWARON GENOA - #1 2009 Nationals!!!
The San Diego GP-7TW genoa is rounder in the front and straighter in the back (especially in the top of the sail). This makes the groove wider when sailing in waves and also makes the sail depower faster when the sheet is eased slightly as the wind pipes up.
"We used the new San Diego Twaron genoa that I thought was especially fast in the breezy conditions we had. My feeling has always been that the San Diego sails are especially good in a little stronger breeze but I also felt like we could go well in the lighter winds too. " -- Chris Snow, 2009 National Champion |

SAN DIEGO KW-1 JIB
The KW-1 Jib is a tri-radial Dacron jib. This design has been
tested and proven in the consistently strong breezes of San
Francisco Bay. The Tri-Radial design of this sail makes it super
low-stretch which is very important for a sail that will be
used in 18-30 knots of wind.
-
We have beefed up the vision window with "bulletproof"
glass and added nylon hanks to the luff to save weight. Switching
to nylon hanks saves about 2 pounds in the all up weight of
the sail, significant when that weight is located aloft and
the sail is used in waves.
-
The design of the KW-1 Jib features a very straight exit
which helps you to keep the boat flat. Ease the sheet 1/2" and
the leech of this sail really opens up and depowers!
-
With the KW-1 Jib you will find the boat much easier to steer
in the big breeze and heavy chop that this sail is designed
for.
-
Jibs include: vision windows and roll bag.

SAN DIEGO FR-2 SPINNAKER
#1 2009 North Americans & #1 2009 Nationals!!!
After many hours of on the water testing and computer studies by the North One Design designers, we have finally reached a product that will make a difference in the J/24 class, especially on windward/leeward races.
The image on the right compares the design shape of the new FR-2 (red) to the previous San Diego spinnaker (blue). The head has been flattened so that it flies wider, and the center seam is more upright. The bottom has been refaired so the lower leeches fly more open underneath the middle of the sail. The objective is to make the sail fly more open up and down the luff. The result allows the pole to be flown lower with more projection and a luff that breaks evenly along the entire height of the sail. FASTER.
For more details about the new design, please contact Chris Snow in our San Diego loft. Chris used the FR-2 to win the 2007 J/24 North Americans.

"I want to let you know that the new FR-2 spinnaker is VERY FAST. The FR-2 will be my first choice and easily it is clearly faster than other J24 spinnakers in our fleet. We were always faster downwind."

"Hi Chris, We are back in Argentina after sailing the J 24 Worlds in Osaka.Talking about the regatta, we established an early lead but a typhoon near Japan brought calm and very shifty conditions for the last 3 days of racing. On the last race we were tied with Kazuyki Hyodo from Japan, but we did not define it well, so we finish second overall. The sails arrived perfectly. They look perfect as usual, and we always have a speed edge especially when the wind increased. The good news for you is that North Sails made 1, 2 and 3. Thanks again for everything." -- Domingo Contess |

"I can not tell you enough how valuable the information was that we got from the clinic. Charlie Enright was on target with the detail he provided for the J/24 group. Thank you for bringing them to Lake George." |
