International 420



The High Performance International 420 is one of the most popular Junior Class boats around the globe. With North Sails worldwide contacts and design input, we continue to help refine the sails for top performance.

Our 420 designs are faster than ever!  Don't hesitate to contact our 420 experts to learn more about making your 420 fly!


M-9 Mainsail

Japanese Design!

The M-9 is the new design which has a deeper bottom-middle shape. It is combined with a comfortably balanced shape at the top section making trimming easier. In vang-on conditions, high boom-vang tension adds mast bend down low. The M-9 has designed curvature in this region to improve the performance in this condition.

Easy to handle, easy to trim and easy to accelerate.

M-9 mainsail features:

  • 420 insignia
  • Sail numbers
  • Spreader window
  • Battens
  • Telltales
  • Sail bag
  • Class button

Order Online  - USA only or, contact the 420 experts or your local North Sails dealer.





M-7 Mainsail

Japanese Design!

The M-7 Mainsail is our famous Japanese all purpose design sail. The full radial sail is compatible with both the Selden and Super Spar rigs and is manufactured from Dacron HTP-165 square. It is very slightly flatter than the M-9 in the base of the sail and is suitable for light to middle weight teams.

M-9 mainsail features:

  • 420 insignia
  • Sail numbers
  • Spreader window

J-12 Jib

Japanese Design!

The J-12 jib has a significant improvement in performance by making the exit straighter and having 3 battens to stabilize the leech, holding power and increasing the leech area. Carbon batten are used to minimize weight for durability and performance.

J-12 Jib features:

  • Window
  • Tack cleat
  • Telltales
  • Sail bag
  • Class button

S-05 Spinnaker

Designed by the Olympic winner designers of North Sails Japan is now available in the US.

This is designed based on S-01 to make it fuller and stable which makes trimming easier.  It works well especially in choppy water. However it has a bit smaller project area than S-01.

One lens foot panel was added under new rule. the shape is exactly the same as former S-5.

S-01 Spinnaker

Designed by the Olympic winner designers of North Sails Japan is now available in the US.

The design built based on our most popular 470 design performs great at both running and reaching. Biggest project area, easy to trim, good organized balanced depth through top to bottom makes the trimming easier. As the depth itself is a little flatter, you can play the spinnaker pole height to make it stable when required. Having the spinnaker with maximum area but flat means the sail is fast on both the reaching legs and also the run.

One lens foot panel was added under new rule. the shape is exactly the same as former S-1.

Introduction

The purpose of this tuning-guide is to give our clients in the 420 class some guidelines on how to get the most out of their North Sails.

Follow the guidelines, but always experiment and try finding your own trim. The weight of the crew, the balance of the boat, the stiffness of the mast together with specific local wind and sea conditions all have influence on the fastest and final trim.

Mast Step

Measured from the inside of transom to the back of the mast 2830 mm.

Spreaders

The spreaders are the key to setting up the right amount of pre-bend in the mast. Time should be taken to get the right pre-bend settings for your mast. The best way to measure this is to run the halyard from the tip of the mast down to the black band at the bottom of the mast. Then at spreader height measure the distance from the back of the mast to the closest edge of the main halyard.

This should be done with rig tension on, mast rake at base setting (19’11 ½, tension 30), and no chocs.

Spreader length - 470mm
Pre-bend Superspar M7 – 45mm (+-5 depending on weight)
Pre-bend Kappa – 40mm (+-5 depending on weight)

*Pre bend depends massively on your crew weight, as as soon as they go on the wire they will bend the mast substantially. If you are a slightly heavier team reduce the pre-bend slightly and if you are lighter, finding yourself getting overpowered early increase the pre-bend slightly.

Mast Rake

Mast rake is measured by attaching a tape measure to the main halyard, hoisting it to the top of the mast and then measuring to the back of the transom with the rig tension on and NO CHOCKS. To insure the tape measure is pulled to the same place every time, take a measurement from the tip of the mast to the black band.

Rig tension is measured off the shrouds with either a Superspar or new Loos tension
meter, Superspar meter being the first figure and Loos being the second.

 Wind Speed Mast Rake Rig Tension
 2 - 6 knots 19'11 1/2" 29/29
 7 - 11 knots 19'10" 29/29
 12 - 16 knots 19'8 1/2" 30/30
 17 - 23 knots 197" 30/30

*As a rule, once the boom is going out of the back quarter, it is time to rake back to your next setting, this will be earlier for lighter teams
** Get the above setting and note shroud position and tension on mast.

Chocks

Ideally carry 3 x 15mm chocks and one half chock.

The chocks are the major adjustment for controlling pre-bend on the water, and the amount of power in the rig. Placing chocks in front of the mast will decrease the amount of pre-bend and increase the power in the sail. If you place too many chocks in front of the mast you will find the mainsail leech will become very stalled, so remove chocks.

In very light winds, especially in flat water, you want to flatten the mainsail helping airflow over the sail, back chocking (placing chocks behind the mast) can help this. Back chocking has an amazing effect up the whole mast.

Back chocking can also help to stop the mast from inverting when reaching.

Kicker

In light winds pull just enough kicker to take up the slack in the system, the kicker should not be applying any tension to the leech, or you will loose power and close the leech. As the wind increases and you have to start easing the main (when the crew is flat wiring) add enough kicker so that when the mainsheet is eased leech tension is not lost. As the wind increases and the boom is constantly away from the centre-line use enough kicker to control the leech. The sail should not be allowed to twist too much or pointing will be lost and the boat will become hard to control.

Cunningham

This should only be used as the boat starts to get overpowered. When it is very windy
pull the cunningham hard.

Outhaul

The outhaul should be left relatively tight at all times apart from very choppy conditions where looking for more power.

 Wind Speed Kicker Cunningham Outhaul
 2 - 6 knots Eased Eased Tight
 7 - 11 knots Remove slack Eased Ease approx.
 2cm in chop
 12 - 16 knots Control leech tension Remove creases
 as overpowered
 Tight
 17 - 23 knots Control leech tension Pull harder as
 more overpowered
 Tight

Mainsail Leech Tension

Use the leech tell tails to indicate how much mainsheet tension should be applied. Most of the time look for the tell tails to be flying about 90% of the time.

Mainsheet Strops

It is critical to get the boom as close to the centre-line in light to marginal winds. This means careful adjustment of the strops and marking them. If the boom is off the centreline then pointing will be lost.

With the new strop system, in very light winds, especially in chop it is possible to get the boom slightly to windward.

Top Batten

In light air push the top batten in lightly. In medium winds more firmly to insure the creases are removed.

Centreboard

In very light wind the centreboard can be raked very slightly forward. As the wind increases set it to vertical (mark) and then as the boat starts planning begin to rake the plate back.

Jib Settings

Sheeting the jib correctly has a major effect over the boat speed of a 420. Therefore it is important to mark the jib sheets to ensure that fast settings can be repeated.

Tie the boat to the trolley and place on a beat. Sheet both the main and the jib and and look at the slot from behind. Look to get the slot parallel all the way up between the mainsail luff and jib leech.

Make sure the jib is in tight, then ease it one inch and pull the windward jib sheet(barberhauler) on quite hard and cleat it. Doing this pulls the clew inboard around 3 inches and creates a more efficient slot shape. With a waterproof pen, mark the jib sheet and barber hauler so that these settings can be referred to once afloat. These will not be the exact positions you want to sheet the jib to, but means that fast settings can be reproduced once found.

Jib Height

Set the jib on the forestay so that the foot of the jib is just touching the deck when jib cunningham is applied.

Jib Cunningham

Pull the jib cunningham just enough to remove the creases on the luff of the jib. When the wind is very strong tighten this as you would with the mainsail (note you do not have to pull as hard).

420 Technique

  •  Light wind – flatten the sails, long strops to centre-line the boom, keep the leech telltails flying as much as possible. Crew nice and low on the leeward side out of the slot.
  • Medium wind - just beginning to ease sheet. The crew should work very hard here
    to keep the boat flat so that the helm does not have to ease the mainsheet and loose leech tension unnecessarily.
  •  Strong wind – work the mainsheet hard at all times and keep the boat flat. If the mainsheet is constantly going out of the back quarter then either rake back or
    raise the centreboard.
