Pro Tips to Hauling Out

Every skipper should go through a “what-if” scenario when considering a specific place to haul. These “what-ifs” include the potential impact of gale or storm-force winds, a significant tidal rise, and torrential rain.

Low-lying facilities exposed to the most volatile wind direction can spell trouble, as can a yard thats notorious for catching rain water runoff that turns a hard pan surface into soupy muck-destabilizing the jack-stands that support the blocked up boats.

During hurricane season, tidal surge presents the biggest concern there, but it is usually the vessels in the marina rather than those blocked up on land that suffer most. In winter, volatile storms can pack the punch of a tropical storm, so whether afloat or on dry land, a vessel needs to be able to endure the onslaught.

Equipment & Operator Skill

Frayed lifting slings, deteriorated pilings, and rusty machinery may still work, but more often than not, they are signs of the overall quality of workmanship that a boatyard has to offer. Those seeking lowest-cost options need to be especially aware of how their boat will be hauled and handled. When all is said and done, its hard to beat a new or well-maintained Travelift or hydraulic trailer. Equally important is the dock or ramp it operates on. But no matter how good the gear, the skill of the operator is the most important variable of all.

With sailboats, sling placement is crucial, and the geometry of the hull shape in conjunction with the cable lead adjustability on the lift will determine how equal the sling loading will be. Also critical is the cable angle, a factor that can lead to sling slippage, and in extreme cases, a vessel being dropped. A skilled operator will know how to handle various hull shapes and what rigging must be undone to fit a vessel into the confines of a Travelifts web.

One bit of boatyard wisdom worth remembering: “Being told that yours is the biggest vessel ever hauled by the facility should not be confused with words of encouragement.”

Cranes up the ante for concern, and their operation requires extreme care, especially if they are used to transport a vessel once it is hoisted from the water. Bulkhead collapse, tire failure, and shifting ground can set the stage for disaster. Hauling via a Travelift, hydraulic trailer, and even the venerable marine railway are usually better options. Above all, if your boat is being hauled by a crane, be sure the operator uses “spreader bars,” a cage that keeps the sling load from compressing the hull.

Our tool of choise is a conventional Travelift that runs out onto a well-supported lift pier. Their setup is well protected from wind and sea. Ideally, the lift operator has decades of experience, and knows both the capacity of his lift and the challenges of any given vessel.

When it came time to haul PS test boat, an Ericson 41, the operator had us turn the boat around, release the back stay, and with runners set, he hauled the boat stern first. This was easier than removing a headstay and inner forestay, and allowed for better sling spacing. The efficient haul was followed by a thorough high-pressure wash down that removed all soft marine growth, leaving behind only a few tenacious barnacles at the bottom.

Blocking and Shoring

Standing up a vessel thats designed to float can be a challenge. In many cases, the hull skin is too thin to take the heavy point loading associated with too few blocks under a keel or near overextended pads or jack stands.

Properly executed, the blocking and shoring process is a means of spreading contact loads and rigidly supporting a vessel in a vertical position. Sailboats with external ballast easily endure the pressure imposed by keel blocks but may be troubled by the hull weight pressing down and flexing the keel/hull joint. Many lightly built race boats are fitted to special cradles that spread loads to numerous large contact points and allow the keel to hang.

In gale-force conditions, some race boats stowed in such a fashion, especially those stored with their masts still stepped, have been known to develop a pendulum-like keel motion that can capsize the cradle-supported boat. Wedging the keel bulb to prevent such an oscillation makes sense.

In our case, the yard crew used plenty of timber blocks for keel support and cross chained screw-jack poppets to provide both athwartship and fore and aft stability.

There is a subtle but significant difference between these three-legged stands. The ones with a narrower base are less stable and harder to use effectively. When supporting a sailboat with tripod-like jackstands, the idea is to extend an imaginary right-angle line from the hull skin to the ground at every pad point, and make the jackstands centerline axis coincide with this line.

The more it diverges, the more theres a tendency to “kick out” a stand if the vessel starts oscillating in high winds. Chaining the stands together lessens this likelihood.

Once a boat has been shored and blocked, its a good idea to layer tarps or plastic sheeting beneath it. That keeps cleaners, paint, paint removers, and other chemicals from contaminating the ground. Layering the tarps means you can remove a soiled one and have a clean surface to kneel or stand on.

Darrell Nicholson, editor of Practical Sailor, grew up boating on Miami’s Biscayne Bay on everything from prams to Morgan ketches. Two years out of Emory University, after a brief stint as a sportswriter, he set out from Miami aboard a 60-year-old wooden William Atkin ketch named Tosca. For 10 years, he and writer-photographer Theresa Gibbons explored the Caribbean, crossed the Pacific, and cruised Southeast Asia aboard Tosca, working along the way as journalists and documenting their adventures for various travel and sailing publications, including Cruising World, Sail, Sailing, Cruising Helmsman, and Sailing World. Upon his return to land life, Darrell became the associate editor, then senior editor at Cruising World magazine, where he worked for five years. Before taking on the editor’s position at Practical Sailor, Darrell was the editor of Offshore magazine, a boating-lifestyle magazine serving the New England area. Darrell has won multiple awards from Boating Writer’s International, including the Monk Farnham award for editorial excellence. He holds a U.S. Coast Guard 100-ton Master license and has worked as a harbor pilot and skippered a variety of commercial charter boats.
