Design and Construction
The Melges 40 is a canting keel, all-carbon, strict one-design grand prix racer, and at just 3,200 kg it sits some 800 kg lighter than a Fast 40+ anchor. The hull carries a carbon fin keel that electrically cants to 45 degrees, setting a 1.1-tonne bulb on a 3.4-metre carbon fin, with a fin weight of just 100 kg and a bulb of 1,100 kg anchor. Rather than twin daggerboards cluttering the deck, the boat uses a single centreline canard controlled on a simple purchase system by the pit crew, keeping the working area clear anchor. Twin rudders and a retractable bowsprit complete the underwater and forward-end architecture. The keel technology itself is manufactured by Cariboni and is a direct development of the IMOCA and Volvo 65 systems, using a single ram with a double-acting cylinder that both pushes and pulls anchor.
Rig and Sail Plan
Aboard, the boat carries yards of sail area aloft on a two-part twin-spreader high-modulus Southern Spars rig that is deck-stepped and set with EC3 composite rigging anchor. The sailplan is enormous: a 72 m² square-top main and a 49 m² jib give 20 per cent more sail area than a Fast 40+, and a broad-shouldered 200 m² spinnaker flies from the retractable bowsprit anchor. The rig uses TP52-style deflectors controlled by a PCT-developed magic wheel, one of four such systems on board, and masthead and jib halyard locks are fitted anchor. Botin Partners describe a huge sailplan and a very tall rig, and the two-piece rig offers adjustability at the forestay and mast butt anchor. Runners and a big square-top main round out a rig built for outright pace.
Performance
The boat accelerates really quickly and, in the designer's words, will go 23 to 24 knots anchor. Sailing World recorded a downwind polar of 17.15 knots at 20 knots true wind speed, while testers noted the class makes 22–23 knots downwind and that the keel position upwind is usually fully canted to 45° anchor. The bulb, roughly half the weight of a Fast 40+ bulb, still delivers 10 per cent more righting moment, a remarkable efficiency of the canting configuration anchor. With a 20 hp diesel and the prop lifted before racing, the hydraulics run off two batteries for the canting keel; after three races there is usually still 60 per cent of battery capacity left, so the boats should be capable of two days racing autonomously anchor.
Racing Format and Crew
This is not a boat for short-handed sailing. The class sails with nine or ten people up to a maximum crew weight of 750 kg, and Sailing World states eight to nine pro crew are required to race the boat anchor. The aft pedestal is a six-speed Harken MX Air unit fundamental to operation, and a simple keypad on the turn of the cockpit at the helmsman's back leg lets the tactician or runner trimmer work the keel anchor. A pedestal at the back of the boat centralises the grinding and trimming stations for a coordinated pro crew.
The Verdict
The Melges 40 is a singular object in the grand-prix one-design world: a lightweight, all-carbon canting-keel racer with more sail and more righting moment than its nearest rivals, engineered from offshore racing systems and built to a strict class rule. It is uncompromising, demanding a full pro crew and offering nothing to the cruiser.
Pros
- Only canting-keel production one-design yacht in the world
- 800 kg lighter than a Fast 40+ with 20 per cent more sail area
- 10 per cent more righting moment from a half-weight bulb via 45° cant
- Cariboni keel system derived from IMOCA and Volvo 65 technology
- Reaches 22–24 knots downwind with autonomous two-day race battery capacity
Cons
- Requires eight to ten pro crew; no short-handed capability
- Pure grand-prix racer with no accommodation or cruising provision
- Deep 3.2 m draught and bulb-on-fin architecture limit versatile berthing
