The Laser 4000(now "4000") is a racing dinghy designed by Phil Morrison crewed by two persons. Its one-design weight-equalised system enables physically differing sailors to compete on a level playing field. It is most popular in Europe, particularly the UK, France and Italy.

Contents

The 4000 is a fast, planing skiff-style dinghy with a trapeze for the crew and trampolines for the helm. Upwind, the boat does not point especially close to the wind, but its fully battened sails give enough power to keep up with similar-sized boats. Downwind, however is where the boat excels due to its asymmetrical spinnaker (a.k.a. gennaker). In a force 3 the 4000 will plane and the crew will make full use of the trapeze wire. However, force 4-5 is when the boat performs its optimum. The 4000 is fast enough to make use of the apparent wind to reach the bottom of the racecourse sooner.

In lighter winds, many crews make use of the jibing gennaker pole when sailing downwind. This allows them to show a larger part of the spinnaker to the wind whilst sailing further away from the wind direction.

Features

The Laser 4000 was designed in 1994 by Phil Morrison. It is a sloop rigged dinghy constructed from fiberglass. It features a single trapeze as well as an open, self-draining cockpit. Instead of a conventional kicking strap it features a gnav system, which pushes down on the boom from the top, instead of pulling from the bottom. This allows greater space for the crew to move from side to side. Boat manufacture is well known to be of a very high quality and durability, thus hulls from the very first molds are still competing effectively.

However recently Laser has handed over the rules and administration of the class to the Laser 4000 class association and thus there is significant scope for boat improvement. Many people want to see the addition of carbon spars and lighter hulls (nickname = 4 tonner!). However, the class is adamant that it will stay a one class design and not a class open to unlimited modification such as the International 14 class.

Friendly competition

Over the years the Laser 4000 events have given the fleet a reputation as competitive but friendly, with the day's racing followed by lively evening socials. The equalisation system coupled with relatively low sheet loads mean that a good variety of people are able to sail the boat.

There are currently 3 very populated and active classes in Italy, France and the United Kingdom. The 2023 Eurocup will be held in France and the 2024 Europeans will be in Riva del Garda.

Equalisation system

A long-running problem in dinghy racing is that light sailors are faster in light winds due to their lesser displacement and heavier sailors gain speed in stronger winds due to their increased righting moment. In the early 90s Laser addressed this problem with their equalisation system for both the Laser 5000 and Laser 4000.

When racing one of these boats, lightweight crews are required to carry up to 4 lead weights in their boat (securely fastened in the centre). To compensate for their lack of capsize-preventing leverage, they are also allowed to extend the boat's rack outwards, effectively making the boat wider. Conversely, heavier crews will carry fewer weights, but must sail with narrower racks. Thus each team's total weight and leverage is equalised. The Laser 4000 equalisation system accommodates helms and crews weighing from 59 to 94 kg (130 to 207 lb) each. Beyond that range the traditional wind strength advantages and disadvantages come into play.

Years of competitive racing have proved the system to be effective with all sizes of crews winning in all wind strengths. Several other racing dinghy classes have adopted a similar equalisation systems.

As with many modern racing dinghies, the Laser 4000 is one-design, meaning that strict rules govern the modification of the boat, its sailing and equipment. This is to prevent an expensive competition of "modification racing", where only those who could afford the latest gadgets would stand a chance of winning.

Dinghy sailing is the activity of sailing small boats by using five essential controls:

Dinghy racing is a competitive sport using dinghies, which are small boats which may be rowboats, have an outboard motor, or be sailing dinghies. Dinghy racing has affected aspects of the modern sailing dinghy, including hull design, sail materials and sailplan, and techniques such as planing and trapezing.

<span class="mw-page-title-main">49er (dinghy)</span> Olympic sailing class

The 49er and 49er FX is a two-handed skiff-type high-performance sailing dinghy. The two crew work on different roles with the helm making many tactical decisions, as well as steering, and the crew doing most of the sail control. Both of the crew are equipped with their own trapeze and sailing is done while cantilevered over the water to the fullest extent to balance against the sails.

<span class="mw-page-title-main">Hiking (sailing)</span> Sailing action

In sailing, hiking is the action of moving the crew's body weight as far to windward (upwind) as possible, in order to decrease the extent the boat heels. By moving the crew's weight to windward, the moment of that force around the boat's center of buoyancy is increased. This opposes the heeling movement of the wind pushing sideways against the boat's sails. It is usually done by leaning over the edge of the boat as it heels. Some boats are fitted with equipment such as hiking straps and trapezes to make hiking more effective.

<span class="mw-page-title-main">Hobie Cat</span> Small sailing catamaran

Hobie Cat is a company that manufactures sailing catamarans, surfboards, sailboats, kayaks, stand-up paddle boards, and pedalboards as the Hobie Cat Company. It was founded in 1961 by Hobart Alter, who originally manufactured surfboards. Its line of products has included more than twenty sailing craft, plus a variety of other watercraft.

In a keel boat, a death roll is the act of broaching to windward, putting the spinnaker pole into the water and causing a crash-jibe of the boom and mainsail, which sweep across the deck and plunge down into the water. The death roll often results in the destruction of the spinnaker pole and sometimes even the dismasting of the boat. Serious injury to crew is possible due to the swift and uncontrolled action of the boom and associated gear sweeping across the boat and crashing to the (now) leeward side.

The 18 ft Skiff is considered the fastest class of sailing skiffs. The class has a long history beginning with races on Sydney Harbour, Australia in 1892 and later in New Zealand. The boat has changed significantly since the early days, bringing in new technology as it became available. Because of the need of strength, agility and skill, the class is considered to be the top level of small boat sailing. Worldwide this boat is called the "18 Foot Skiff". It is the fastest conventional non-foiling monohull on the yardstick rating, with a score of 675, coming only third after the Tornado and Inter 20.

The Laser Stratos is an all-round cruising and racing boat designed by Phil Morrison and built by LaserPerformance, the same company as the famous Laser Standard dinghy. It is built from fibre-glass and foam sandwich. The Laser Stratos comes in two forms, one with a keel and one with a centreboard. The centreboard version is red and the keel version is blue. The Stratos is quite spacious and most of the rigging is kept out of the way. The boat can optionally be fitted with trapeze lines and an engine bracket for carrying an outboard engine.

The Laser 3000 is a racing sailing dinghy crewed by two persons with a trapeze for the crew. Launched in 1996, the 3000 was developed from the Laser 2, using the original Frank Bethwaite-designed planing hull combined with a brand new self-draining deck by Derek Clark. Clark also re-designed the rig, using spars and sails from premium proprietary sources and replacing the symmetric spinnaker of the Laser 2 by a larger asymmetrical spinnaker. The gennaker is chute-launched and retrieved using a single halyard line, and is set on a retractable bowsprit. Helm balance and handling were improved using a shorter-footed mainsail with two full-width battens giving a larger roach. A mast with conventional spreaders replaced the now-unusual diamond arrangement of the Laser 2.
