Corrosion....

Galvanic Corrosion Thoughts…To avoid or reduce wastage -

• Thoroughly and carefully coat or paint metals especially in galvanic cells.

• If a coating is used, then use it on the cathode (the metal which is not going to corrode) because coating the zinc anodes will reduce their surface area. Reduce the area of the cathode not the anode.

• If dissimilar metals are causing unwanted corrosion – then one or more of the following should be done –

• Electrically isolate dissimilar metals.

• Select metals that are close to each other on the galvanic series.

• Change the potential between metals (anodes – impressed current systems).

• Properly wire vessels to ABYC standards – no ground and neutral lines connected.

• Use galvanic isolator – transformer.

Anode Selection

• Zinc – Salt Water (make sure to use Military Spec M 18001J zinc anodes).

• Activated Aluminum – an alternative to zinc in sea or brackish waters. Both zinc and activated aluminum do not work well in fresh water unless cleaned monthly.

• Magnesium – Freshwater, potential excessive protection in seawater (short life).

Port Orchard Yacht Sales

It's a cold, dark, rainy day here in Western Washington - so there's no better place to hang out than Robert Heay's Port Orchard Yacht Sales. Robert has owned POYS for the past 27-years - combined with his 30+ years of sailing experience - makes this yacht brokerage one of the best on the west coast. Stop by and say hi to Rob, Trish (the Fab) and Ken. 360.876.4584.

Sail Rig Inspection....

Sail Rig inspection guidance from the USCG Sector Honolulu Inspection Note Number 13

- Weekly - all rigging hardware at deck level be thorough cleaned and rinsed.

- Monthly - a thorough inspection of all rigging equipment.

- Annual – a comprehensive (mast standing) inspection of mast and rigging system with rigging slacked off, turnbuckles opened and lubricated with rigging properly tension and re-tuned.

- Every six (6) years - mast removal and disassembly of all components for comprehensive inspection.

- Replacement of stainless fittings every five (5) to ten (10) years for vessels operating in the tropics.

- The USCG Sector Honolulu Inspection Note Number 13 refers to a six (6) year “cycle” – Replace wire every 6 years, terminal fittings every twelve (12) years, and chain plates every eighteen (18) years. This may be as a result of the “tropics” and the beating it gives to stainless steel rigging. Mariners have all seen rigs that are well over ten (10) years old that appear to be in serviceable condition. A conservative estimate may be to use the “six year cycle” for those vessels operating in the tropics. Then move to possibly an “eight year cycle for those operating on the “coasts”. With a “ten year cycle” for those vessels that are used in the northern climates.

Fuel Hoses.....

- Flexible fuel hose used in marine applications must meet the requirements of SAE J1527 and must be marked as such (ABYC H-24 and H-33). Flexible fuel hose for marine use is rated for specific applications using a letter – number combination. The United States Coast Guard (USCG) has designated four types of marine fuel hoses – viz., A1, A2, B1, and B2. The USCG requires fuel hose approved for marine applications to be marked “USCG Approved Type __” every twelve (12) inches – along with the date of manufacture (see photograph below of a section of USCG Approved A1 marine fuel hose which is marked fire and alcohol resistant). ABYC Sections H-24 and H-33 specifies fuel hose types and usage for gasoline and diesel fuel systems. Newer alcohol based fuels will cause older approved hoses to deteriorate and leak. Each flexible fuel hose end must be secured by a swaged sleeve, and sleeve – threaded insert, or a corrosion resistant hose clamp. Note – not all Type A hose is designed to be clamped.

Type A1 hose is for critical fuel delivery applications for both gasoline and diesel fuel products due to its good fire resistance and low permeation characteristics. 33 CFR 183 requires that A1 or A1-15 hose be used for inboard gasoline machinery fuel systems. ABYC H-33 recommends either A1 or A2 for diesel fuel applications within engine compartments. Type A1, A1-15, and A2 hose is required and or recommended for vent and fill applications. Type B1 and B2 fuel hose is also recommended for use as vent and fill hose outside the engine compartment where a break in fuel systems will not result in the discharge of not more than five (5) ounces of fuel in 2-1/2 minutes. All fuel delivery, fill, and vent hoses must be of proper specifications. The use of non-marine grade hoses, such as used in automobiles, is not recommended. Gasoline and diesel fuels have a profound effect on hoses. Fuel hoses should routinely wiped with a clean, dry cloth to check for excessive fuel order which could indicate leakage.
