Windlasses For over four decades the name Maxwell has been synonymous with the highest standards of excellence in marine engineering. By providing superior anchoring solutions for pleasure boats, superyachts and commercial vessels, Maxwell has earned a global reputation for quality without compromise. A reputation built upon ongoing research and development, innovation in design and a commitment to style that is unparalleled in the industry. Maxwell has become an industry leader by analysing the needs of boats and boat owners around the world and producing equipment that consistently exceeds customer expectations. Maxwell Marine has enjoyed a period of expansion and broadened horizons. As a company trusted for delivering on the promise of anchoring excellence, Maxwell Marine continues to supply a growing product range. Maxwell Marine is represented by a strong international distribution network, a proven track record and a portfolio of products that are at home on many of the world’s finest and most admired boats. The quality of Maxwell Marine products and their performance as a company is assured by its certification under the stringent requirements of ISO 9001 and CE. In addition to their head office in Auckland, New Zealand, Maxwell Marine has a separate Maxwell America LLC operation headquartered in Maryland, USA. Australia is served by a Maxwell sales and distribution centre in Queensland. Europe, the Middle East and Africa are now being served by a dedicated sales and distribution centre based in Schiedam, Holland. An extensive global dealer and service network supports these main centers. Important points to be considered for selecting windlass! 01 - Whichwinch? There are a number of important criteria to be considered in selecting the correct anchor winch. These include the vessel size, displacement, windage, anchor size and rode selection. Maxwell Marine’s range of windlasses and capstans is extensive, with models to suit boats up to 120 meters (over 380 ft). 02 - What size windlass or capstan for my boat? Consider the overall length and displacement (either light or heavy) of your boat and use the chart on the opposite page to identify the most suitable windlass or capstan for your vessel . 02 - Vertical or horizontal configuration? The two basic types of windlasses are differentiated by the drive shaft orientation. Deck thickness and underdeck space are the two main considerations when deciding which of the two types to fit. Vertical windlasses make up the majority of anchor winch sales. They are characterised by situating the capstan and/or gypsy (topworks) above the deck and the motor and gearbox below. Vertical windlasses provide a 180° wrap of the anchor rode around the chainwheel giving optimal chain control, minimising slippage and jumping. Horizontal windlasses are mounted completely above deck with gypsy and capstan located to either side. They provide a 90° wrap of the anchor rode around the chainwheel. 03 - Howmuch space do I need inmy chain locker? Deck thickness and locker space play an important role in deciding whether to install a vertical or horizontal windlass. Estimating or measuring the depth of fall of the rode into the anchor locker may dictate which type of windlass is most suitable for your vessel. 04 - Rope selection Rope and, particularly chain, selection is extremely important. Deciding on the right anchor winch for your boat depends on the size, not only of the boat, but also the ground tackle. Maxwell anchor winches and capstans are designed to take chain only, rope only or a combination of both. Automatic rope/chain systems are now commonly used on boats up to 22 metres (75 feet). Chain only systems remain popular on heavier displacement sail and motor yachts. There are two main types of anchor chain. Short link chain is most commonly used on small and medium sized boats while stud link chain is generally used on much larger vessels such as Superyachts. If the chain is not matched to the chainwheel problems may occur, such as the chain jumping off the gypsy or the chain jamming as it will not feed smoothly through the chain pipe. 05 - Howmuch rope? 8 feet of rope for 1 foot of anchoring depth 06 - What rope diameter? 1/8” of rope Ø for 9 feet of boat length 07 - DC, AC or hydraulic? The wattage of a DC electric motor is not the important factor. Rather it is the efficiency of the whole winch, including the gearbox and motor, which counts. With the increasing popularity of powerful and compact on-board generators, AC powered winches are becoming a practical consideration for bigger boats. Hydraulic systems provide another power source well worth considering as they have the advantage of constant speed under all load conditions and can be run almost constantly while coupled with safe guards such as pressure relief valves. Modern hydraulic systems offer an integrated, low maintenance and efficient, centrally managed, power pack. 08 - What pull capability will I need? The only meaningful way to rate anchor winch performance is by looking at what it will lift and at what speed. The two things to consider are (a) the maximum pull capability and (b) the working load of the winch. Maximum pull (sometimes referred to as stall load) is the maximum short term or instantaneous pull of the winch. Working load is generally rated at about one third of the maximum pull and is usually considered to be the load that the winch is pulling once the anchor is off the bottom. To determine your required maximum pull capability, complete the calculation below. Maxwell clearlymentions themaximumpulling capacity of all it’s windlasses! The motor power is the current it draws multiplied by the battery voltage, measured in watts. The figure quoted by manufacturer is normally a nominal one, at light load. However the pulling power depends on the ratio of the gearbox that connects the motor to the gypsy, and the diameter of the gypsy. The higher the gearbox ratio, the more pull you will get from a given motor. Similarly the smaller the gypsy diameter, the greater the pull. The key factor is how long they can sustain the different loads. A good windlass should be capable of running for at least two minutes at its maximum pull capacity. Some manufacturers do not even mention this information. VS Windlasses are rated either by their motor power in watts, or their pulling power in kg, but the two are not always directly related.
