Successful operations in a shipyard of course depend on good weather as well as efficient, experienced and conscientious operators. But of utmost importance is preparation and planning. It helps when yacht owners plan their haul out and various winter works. Nothing happens without proper maintenance management of the equipment.
US Hoist of CALVERTON on Long Island is Manhasset Bay Shipyard’s partner of choice for its travel lift and trailer. Peter, our yard manager, again has contracted this firm for a full inspection and maintenance of out-hauling and splashing equipment. This overhaul is not taking place on our grounds but instead at their plant. Afterwards, US Hoist will use our equipment at both the New York and Atlantic City Boat shows where the MBSY logo will be prominently displayed. Good planning, Pete! Thank you.
Keep an eye on the re-assembly of the equipment beginning this spring. Next episode: See how crane-operator Mike Cobos assisted in repowering the inboard engine of a Valiant sloop.
It is about time that I formally introduce Alfred, owner of Lizza Rigging!
Before David James smoothly transitioned his shop, “Al” had learned the ropes as a rigger in multiple yards i.e. Cold spring Harbor Beach Club, Sagamore Yacht Club,and Oyster Bay Marine Center. As a rigger, he removes and stores sailboat masts, steps masts, tunes rigging, assesses and repairs damage to rigging, and supplies new lines.
He provides timely mast climbing in cases of immediate need. In the past, Al occasionally performed dock repairs, mooring servicing, bottom painting, and other general marina operations.
As a PADI Certified Open Water Diver, he dove on sail and motor vessels in order to clear marine growth from below water lines and to repair/replace submerged components such as propellers and zinc anodes.
After his formal education in Mechanical Engineering Technology, Al worked in an array of machinery and technical positions. His experience in CNC mills operation, CAD and multiple software such as Solidworks speaks to his problem-solving skills.
Al is a United States Coast Guard Merchant Marine Officer, with Master 50 Gross Tons and Commercial Towing Endorsements.
This panel of skills is now available to us as we maintain our cherished vessels right here in Manhasset. Welcome, Al !
Let’s remove winch grime! Many of us have completed the nautical “Honey Do List” this spring. For the rest of us who have sailed through July and not yet maintained our winches before the yearly cruise in August, here are some ideas…
A couple of years ago, Practical Sailor published a comparative analysis of the different greases to be used during our winch maintenance process. I do not remember however having read specifics about how to clean them!
I recently helped a friend to rig his newly acquired 25-year-old Tartan 31. While raising the main with the deck-mounted winch, my eardrums were assaulted by the recalcitrant clanging and crunching noises that threatened to crush his wallet.
I cleaned enough of these fine pieces of clockwork to ascertain these winches did not received any TLC for at least 12 years. The procedure is always the same:
Bring necessary tools: screw driver, needle plier, very small screwdriver, metric and SAE hex keys and maybe a small rubber mallet. For cleaning, prepare an old tooth brush, a cheap stencil brush, perhaps a brass brush, lots of t-shirt towels, heavy dishwashing gloves. Dawn old clothes: solvents are really stinky.
Create a receptacle such as a tent in which jumping parts would remain contain instead of taking a dive in the juice… Use a cardboard box at bottom of which you can cut a circle large enough to slip over the drum. I like to make a tent held with clips on the lifelines.
Start from the top. It might just be secured by a simple Allen bolt. some times, a spring ring is located in a grove. That’s where the small screwdriver can come into play. On self tailing winches, the top plate can have two holes or two notches. Delicately insert a soft metal tool ( very cheap screwdriver ) alternatively in each side’s notch and tap with the mallet. A needle plier can help here. But you should be able to turn it by hand.
Put all the parts in a bucket. Keep the pieces of each with separate! I use a series of cut-off anti-freeze bottles. Or a “Tupperware”. They resist to solvents.
At the shop, I take pictures and start to wash each part. If possible, follow the instructions of the winch manufacturer. However, as explained later, the winch is so dirty that we have to be more aggressive.
A WeeWee Pad is a good table cover. Doing it outside reduce smells.
Re-grease and remount. Practical sailor published a good analysis of the performance of various lubricants. Do not grease the owls (small cams).
The meat of this particular topic: cleaning!
It is good practice to rinse the winches and other blocks every time possible, to remove salt, sand and grit. Therefore, dunking all parts in plain water is a good start in my maintenance process
Then what solvent could we use? This comparative test is not highly scientific as it only compares four winches on the same boat. Different greases, different frequency and conditions of usage, different climates and different maintenance conditions will affect these results.
I also did not contact the manufacturer to define the way some polyamide or other plastic roller bearing cages could absorb or expand while stagnating in different cleaning products. My results are highly subjective, pragmatic and empirical.
I do NOT use gasoline. Even if most parts are made of bronze, this stuff scares me. Mineral Spirit: dissolves most of the grind, dries fast but leaves some crystallized and mildewy residues on some parts.
Kerosene: smells, but seems to “glide” off the parts. Does not dry as fast as the others, which leave more time to clean crevices and interstices
Diesel fuel: really smells and your first mate will definitely ask you to get out of the cabin!
Simple Green: Overnight bath seem to have worked surprisingly well. It seems that both water borne solutions were effective on grime, but not as aggressive on grease. I found a lot of sediments on the bottom of the cleaning vessels. Simple Green All-Purpose Cleaner is a water-based cleaner with a pH of 8.5 to 9.5. This is very basic and can alter paint and some finish. I did not see any effect on the stainless nor on the bronze parts of the winches I cleaned.
Spray Nine: Worked similarly to Simple Green. It contains Ethoxylated C9-C11 alcohols that are very toxic to marine environment and should be banned from yachts… In fact, I did not finds any advantage versus simple green.
Disposal and recycling: I let dry most of the rugs before disposal in an approved municipal waste site ( your curb side… as per EPA suggests for dry paints ).
Soaps were poured through a coffee filter and stored in separate containers for future very dirty jobs.
Kerosene is in fact a type of Diesel fuel. Since there was no water in it, I filtered it with the Diesel fuel and poured it in my 40 years old Volvo MD11C fuel tank with a full fill. The Racor filter will take care of the minute dust left.
Conclusion ? Kerosene… It seems it lubricates the parts while cleaning.
We certainly endured a challenging winter and recent rains in the month of May did not facilitate launch schedule for any of us. We are in awe as to how “Jambo” keeps its brightwork and varnish in Bristol fashion! ( Click on the picture to enlarge )
We hope that the past enjoyable boating season was safe and enjoyable, and for our returning customers, we look forward to being able to serve you again this year. As we have done in the past we are offering a 3% discount on storage payments made by check by December 31, 2017. We hope that you will all take advantage of this offer.
Please indicate the work you would like performed this fall by initialing the boxes in the chart on page two of the contract agreement. Many of you enjoy doing your own fall decommission and we enjoy seeing old friends in the yard again. But for those of you who would like the Shipyard to decommission your boat, please take the time to initial the boxes – we only do work if it is requested.ease include any special instructions under the work request chart on page 2 of the contract. i.e.: remove jib, pick up after x-date only, remove plug, etc. Sailboats should have headsails removed prior to haul out or we will remove and fold them at a charge of $75. Heads should be pumped clean (we have no capability to pump heads) and keys turned in to the office. We can’t winterize your boat without the keys. In order to keep growing the yard we are offering a 10% discount to current customers who refer a friend. The discount will be based on the size of the new customer’s boat and will be applied to your account upon receipt of a new contract. We want you to know we appreciate your referrals.
