Performance Options

The Lightwave 46 is configured as standard, to suit a cruising orientated sailor. Mini keels protect the sail drive legs and rudders, allowing the catamaran to be beached. The aluminium rig & fore-beam, dimension flex ultra-laminate sails, and foam core fibreglass construction will satisfy most seafarers, however if additional performance is desired, a comprehensive range of options are available. 

Twin Board
For the ultimate performance, twin daggerboards can replace the mini keels. At this level, Lightwave Yachts offers optimal performance packages, from the materials used in constructing of your vessel through to carbon orientated rigging & sail packages.

Helm Position

Unmatched in its class, the helm station delivers full-time protection from the elements, along with 360-degree visibility for an exceptional sailing experience. Uninterrupted sightlines enable clear communication with the crew, whether on deck, in the cockpit, or in the main interior areas. The intuitive design places all navigation and control instruments at the skipper’s fingertips. Featuring a comfortable chair that accommodates two and adjusts for seating or standing, this helm station epitomizes the finest in cruising comfort and functionality.

Engine Room Access

The Lightwave 46 offers safe & comfortable access to the sail drive engines & engineering systems via two large hatches, aft in the cockpit. Opening with ease with the assist of gas struts, they can be easily opened even with the aft safety gates in place. The engines rooms are home to the main engines, generator, steering systems, toilet vacuum pumps and fuel & raw water strainers.

Sailing Systems

Designed with the priority for the ultimate sailing experience, the deck layout and sailing systems are configured for ease of handling while shorthanded. The line system on the Lightwave 46 has been designed so all lines are organised and accessible from an area where the sails can be easily observed. Lines all lead to the cockpit and travel under serviceable fibreglass boards which not only keep the lines organised, but also remove possible tripping hazards. Hanging points are purposely provided creating a neat and organised place for line tails to be stored. Anderson winches and Ronstan deck gear are superiorly selected as standard equipment, with optional electric winches also available. A bridal main sheet system is cleverly applied to eliminate the safety concerns of a traveller car system traditionally used on catamarans.

Engineering Systems

The Lightwave 46 offers a very spacious area in the external engine rooms, to accommodate the standard 50hp engines & other engineering systems. All steering components as well as the optional generator are housed in the engine rooms, carefully positioned for ease of access for servicing and maintenance. The engine rooms are separated from the accommodation area with a bulkhead lined in sound dampening material to defer noise, heat and odour from entering the cabins. The engine rooms are also accessible from the inside of the boat if required.

Electrical System

The Lightwave 46 is designed for self-sufficient blue water cruising. The vessel is supplied with a 12-volt DC and a 240-volt AC electrical system. A 600Ah AGM battery system is offered on the vessel with an optional 660Ah lithium-ion battery bank. There are various solar options producing up to 2000kw of power. There is also the option to have a 4Kw AC diesel generator which is coupled with the inverter to allow for a high output. All areas of the vessels electrics are designed to be easily accessible and traceable with minimal disruption to the boats systems. Electrical components on the Lightwave 46 are carefully selected to ensure a minimum power consumption is achieved. Onboard systems incorporate the latest in technology, allowing remote control and monitoring of critical power systems, battery and charging status, tank levels, bilge pumps, aerial and security CCTV as well as an array of other custom options.

Plumbing System

The Lightwave 46 has 800L of fresh water & 800L of diesel, in tanks that are built directly into the hull. High quality, purpose grade materials are used in this labour intensive construction method which guarantees an extremely high-quality product that will last for the lifetime of the boat. Dual freshwater pumps provided piece of mind through redundancy. A water transfer line is built into the system to allow water to travel between either tank. Fresh water vacuum toilets that use minimal fresh water (less than 400ml per flush) are a standard feature on the Lightwave 46, eliminating the stale saltwater smell that can encroach the cabin area.  A saltwater system is also fitted to the vessel to allow an anchor wash, saltwater tap in the galley and hose in the cockpit.
