Fran Slingerland's article "Cruising Light" ran in the February 2008 issue of SAIL. Below are the specifications and other information about Ninth Charm, the cruising multihull she and her partner sail, as well as comparable information for Secret Affair, a lightweight cruising monohull. She has also supplied some suggestions for keeping light.

WEIGHT-SAVING TIPS AND CONSIDERATIONS
Dinghies and outboard engines. Consider whether you really need an outboard for your dinghy. There are many things to consider here, the primary one being how far you want to row, and how far from shore access you would like to anchor. Remember that without an outboard engine, you will not have to carry the weight of flammable gasoline. You will also get more exercise, but you will have no second line of auxiliary power for your big boat, or to help when other boats drag. It seems that people who have compressors and dive equipment aboard need a larger dinghy and an outboard engine. Ninth Charm’s crew have the ambition of building a new two-part canoe-like dinghy with two sliding rowing seats off rowing sculls, so we can whiz ‘round the harbor at 8 knots under muscle power…
Ground tackle. Is it possible to carry less chain? Get out your spec sheets on working and breaking strength of the chain and line required to anchor your boat’s tonnage. With the miracle of modern nylon braid, it is possible to match the breaking strength of most chain with line these days. What about using 15 meters of chain and a compatible nylon rode for the rest of your required length. This can save you huge amounts of weight and make it possible to raise that anchor if your windlass dies on you. On a lighter boat, less strength is required.
Watermakers. It is simply unnecessary to carry 100 gallons of water for a crew of two. The most you would need for a 30-day-long offshore passage would be 75 gallons, and how often are you out for that long? A 25-lb desalinator can save you a whole lot of weight in water.
Solar power. Consider how much power you are using for your appliances and work it out to amp-hours a day. Then consider reducing usage with more efficient systems and installing solar power.
Compressors and fridges. All fridges are not created equal. They are either engine-driven or electric, and electric fridges range from 2 to 8 amps usage. How much insulation you use can make a huge difference to its power-usage. Electric fridges with no-pump water-cooled compressors are likely the most efficient. For fresh-fruit-and-veg-loving crew like Ninth Charm’s, a fridge allows us to indulge in our cravings. But consider Moemoea of Darwin, who don’t care much what they eat, and have no fridge, but instead carry two dive compressors and several dive tanks!
Music. Convert your CDs to MP3s and send the originals home to a dry cupboard, or to someone else.
