Maintenance

tool_box_250x251Tightened Up

Replacing the trickling, dribbling, leaking and seeping stuffing boxes, dripless shaft seals still need attending to.

By Capt. Ken Kreisler

Ever since the first prop was connected to the first shaft being turned by the first internal combustion engine, there has always been the dilemma of how to keep water from entering a boat through that all-important hole in the hull while also protecting the rapidly spinning shaft from the ravages of friction.

If your boating years go back as long as mine, you are familiar with the steady dripping of the practical, always carefully attended to stuffing box. This most important piece of gear housed a series of packing rings—numbering three to five and often made of braided flax rope—coated with a waterproof material, and allowed the shaft to pass through the hull and keep turning while under power. It also prevented the water from getting in and flooding the bilges. Once properly tightened down by a collar, the rings were compressed enough to allow a few drops of water every minute or so to ‘leak’ in, permitting the shaft and the packing to be cooled enough to prevent scoring the metal surface or ‘burning’ the packing.

With regular routine maintenance, the Tides SureSeal should do its part to keep the shaft well lubricated and running properly.

With regular routine maintenance, the Tides SureSeal should do its part to keep the shaft well lubricated and running properly.

But as with all things in the marine industry, a change was due. Enter the dripless shaft system. Utilizing highly machine-polished, mechanical mating surfaces held together by pressurized tension on a rubber bellows surrounding them, and a hose connection between the intake side of the engine’s raw water pump and the device, they have become the familiar norm in most applications.

One of the big downstream concerns associated with the old stuffing boxes was one created when there was a more than acceptable raw water flow. Sprayed outward by the spinning shaft, the ensuing salty mist would, of course, hasten corrosion to any metal it landed on. With a fully encased design, shaft seals alleviate this problem.

“We were most likely the first to use a rubber lip seal lubricated by raw water from the engine, replacing the traditional packing,” said engineering and quality control manager Skip Lookabaugh for Tides Marine.

Overheating the housing can be trouble. In most cases, this is caused when air is allowed to accumulate inside due to most inboard engine drive shafts being installed on an angle thus creating bubbles that can travel up the shaft. Dripless systems use the pressurized lubrication water to force any air out.

Dirt and grit can get sucked up if you run aground or operate in shallow, sandy bottom areas. And watch out for fishing line as well. “And as with all devices with moving parts, if you notice a slight leak which steadily increases over time, you might want to check inside,” said Lookabaugh. Prevention includes examining the lubrication system, hoses, clamps, and pump, on a semi-annual basis. Lookabaugh also recommends changing the lip seals on Tides’ equipment every five or six years.

According to Duramax, the design features of this system eliminate problems that other systems experience, and with no lip seals or packing to change there is no maintenance. It is easy to install, with no need for constant adjustments once properly installed. Removal and replacement of the system is simple.

Mike Schoenauer, VP Sales & Marketing, and Lou Foster, VP Sales for Duramax also offered some maintenance insight and highly recommend regular visual inspections especially if you have had any work done in the shaft area where someone could have stepped on the seal. With boats that have been sitting idle, there could be scale, sea growth, or some other debris present, they offered. “Also, and while it should never happen, a noticeable bulge in the outer yellow bellows indicates something is causing the inner one to leak and should be taken care of,” said Foster.

“While we do have tolerances built in to allow for some misalignment and vibration, the main problem most boaters would face occurs when something hits the running gear and really throws things out of whack,” said Justin Romesburg, Director of International Sales for PSS. Therefore, it is highly recommended that should there be any alignment or vibration question, make sure you have your shaft seal checked as well.

The shaft seal systems on the market today are rather robust and will have a fairly extended longevity with regular and diligent preventive maintenance. Should you have any questions about your particular dripless shaft seal, it’s best to get in touch with the manufacturer and have it serviced. Keeping your boat on top of the water depends on it.

dockHodgdon Steps Out

Infusing a 100-foot carbon fiber hull places this renowned boat builder in rarefied air.

By Capt. Ken Kreisler

If you’ve been keeping up with my DOCK BUZZ postings, you will recall the 26Feb article on revered boat builder Hodgdon Yachts’ winning a prestigious and well-deserved Showboats Design Award for Fledgling, a limo tender to the 203’/63m, Feadship-built Sea Owl.

The Hodgdon legacy began in 1816 and has continued through five generations of the family launching their prized vessels into the waters of the Damariscotta River on the shore of East Boothbay, Maine.  Through two turns of centuries, world wars and conflict, economic booms and downturns, the name Hodgdon has been associated with visionary and cutting edge boat building.

The 1999 launch of Liberty, a Bruce King design featuring an interior by Allan Walton, harkens back to the commuter express yachts of the 1900's used by Wall Street financiers. She is just one of the many exciting and unique projects Hodgdon Yachts has accomplished in its amazing career.

In yet another move forward, Hodgdon has announced the successful infusion of a 100-foot, carbon fiber hull mold making it one of the USA’s largest, single hull infusions and only one of a few done a worldwide scale. “The amount of planning, organization and coordination required to effect this successful work is formidable,” said Tim Hodgdon, President of Hodgdon Yachts. “Our talented team along with the vast experience and leadership of our project partners Tim Hacket and Brandon Linton continues to strengthen our core competence in advanced composites.”

Hodgdon’s success with infusing large composite parts, such as this 100-foot hull, and along with other boat builders doing the same, will only serve to increase the interest to designers all over the world on the advantages of using advanced composites in their projects as well. “We are pleased to be one of a handful of shipyards in the world capable of executing projects like this, and to be a leader in this technology in the USA”, Hodgdon added.

vintage cameraTo be sure, there’s magic found in many places but none more than that discovered in nature. For all of my life, I have beheld wonderment, been amazed, stood in awe, and had my breath taken away by what I have seen and experienced. The first time I saw a shark come up from the depths and swim around my boat; being caught in a thunderstorm; been out at sea, and out of sight of land; explored coral reefs and sailed under the Southern Cross. I never tire of sunrises, sunsets, the phases of the moon, the change of seasons, and the endless procession of cloud formations that are in constant motion across the skies. I was visiting family when I took this picture. After a brief rainstorm, I stepped outside and saw this double rainbow in the distance. Yet another remarkable moment for my wonderful memories which, here, I am very pleased to be sharing with everyone.-Kyle M., Bundoran, County Donegal, Ireland

Yacht Spotting And New Launches

_Galilei_and_Doge_of_VeniceThe Azimut 80: Continuing The Vision

An exciting approach to both interior and exterior design results in yet another leap forward for this highly respected builder.

By Capt. Ken Kreisler

No matter how you look at it, Paolo Vitelli is a visionary. In 1969, the then young university student had an idea to charter sailboats and, to begin his ascendency in the world of yachting, founded Azimut Sri.

A year later, several prestigious boat builders, quickly recognizing his potential, approached Vitelli with an offer to distribute their boats in Italy. With the new business coming in, Azimut began to expand and was soon designing its own yachts, introducing the AZ 43. By 1977, the line included a 32-foot Targa model and, in 1985, the 105-foot Failaka. The big news, of course, occurred in 1987 when Azimut acquired Benetti, the highly esteemed Viareggio-based builder whose credentials reach back to 1873.

Adding to its impressive line up, Azimut’s 80-foot flybridge has all the qualities of the imaginative Vitelli and his equally talented crews of designers, engineers, and craftspeople that have always been built into every yacht…and then some.

While never compromising on its heritage of designing and producing well-built yachts, Azimut has, with its 80, looked to yet another way to take its use of interior living space to a new level. A minimalistic outlook is the key and to that end, this build utilizes the available layout, furnishing design, and even the latest advances in lighting to create the kind of personal statement any owner would be most proud of. And that includes the living accommodations as well. Here, Azimut designers fill the spaces with the kind of lines, forms, and concepts that results in an elegant and sophisticated end product.

The Azimut 80 shows off her exciting exterior profile along with her equally impressive performance abilities.
