Safety & Seamanship

As high tensile G70 chain becomes more prevalent in the marine market, Practical Sailor has been busy testing the limits of this material, which has been used for many years in other industries. One question we have raised in the past is whether G70 chain can be safely regalvanized (see PS June 2014, Making Sense of Marine Chain Standards). Chain is expensive and regalvanizing helps to extend its life. If G70 chain can't be regalvanized, as we have suggested in the past, this needs to be factored into the initial cost.

I feel for the crew of Tanda Malaika, a family of six whose 46-foot Leopard catamaran was lost on a reef on the southwest corner of Huahine in French Polynesia in July this year. The loss is especially acute because, as the captain himself points out, it could have been avoided. The account of the wreck, provided by the skipper/owner Dan Govatos, and recorded in the podcast Slow Boat Sailing offers important lessons for cruising sailors.

In Part 1 of our special report on multihulls we scrutinized the implications of stability and the benefits derived form a wide stance, buoyancy and hull shape of multihulls. This time well look at structural issues and the energy transfer that takes place due to a multihulls impressive initial resistance to heel. We will also delve into what all this means for the rig, rigging, hull structure and hardware interfaces.

Charles Nethersole has been a professional sailor for decades, and in addition to racing commitments and deliveries, hes accrued 14 years of sea time as a professional captain aboard 55- and 57-foot, Chris White designed, Atlantic catamarans.

Ten years ago, you may recall having seen the Walder boom brake demonstrated at sailboat shows. There wasn't anything quite like it. The device caught on for a time with single-handed racers, who liked the way it slowly eased the boom across during jibes. (Philippe Jeantot had one on Credit Agricole when he won the first BOC Challenge.) When your hands are full with jib sheets and the wheel or tiller, there's too often the tendency not to pull in the mainsheet to minimize the shock load on the gooseneck when the boom slams across to the new tack.

With all of the products out there claiming to be green or non-toxic, surely there must also be villains that are now best avoided. In just a century weve begun to make a fine mess of the world that we need to live in for the next few million years. Yet we are making progress, and finding less hazardous replacements is a part of the answer.

Material Safety Data Sheets must be available to employees and they must be trained to read them. Failure to abide by this rule set by the U.S. Occupational Safety and Hazard Agency is the second-most frequent employer violation. Even when MSDSs are available, few employees ever read them. Culturally, we believe instructions and warnings are a joke. Well, its your funeral … literally.

The loads of a flying jibe in late summer squall are enough to shred sails, rip out deck or boom fittings, bend or break the boom gooseneck, or even bend the boom itself. The novice sailor learns very quickly to be wary of an unintentional jibe.

Ideally, you don't put yourself in a position where an accidental jibe can happen, but even an experienced sailor can get caught off guard by sudden, violent wind shifts in mountainous coastal areas or in night-time squalls. The most common way to take the fright out of an unintentional jibe involves a preventer, something weve examined in a number of previous reports. Preventers are especially useful when sailing deep downwind in rolly conditions, when exaggerated yawing lets the wind sneak behind the mainsail.

Getting over seasickness as quickly as possible must be the focus and responsibility of all on board. Having dealt with 400 seasick sailors (out of 1,200 sail-training students) on ocean passages over the past 42 years, I have become very experienced at prevention and treatment. The following steps to avoid or lessen the severity of seasickness has served well over those years.
