Galvanic Corrosion: What is it and how can we prevent it?
First, what exactly is corrosion? Corrosion is a process of deterioration when metal components are exposed to a wet environment. This occurs both underwater and in the atmosphere. This deterioration is the process of the metal reverting to its oxide form. Steel, for example, will degrade (oxidize) back to its natural stable state – rust (iron ore).
Are you getting excited yet? If not, read on…
Galvanic corrosion occurs when two dissimilar metals (copper and steel in the example below) are connected and submersed in an electrolyte (water) whereby an electric charge is created, like a DC battery. Negative electrons from the negatively charged metal (anode) will flow to the more positively charged metal (cathode). Left alone, the charged metal will corrode away to nothing.
If protection for both types of metal is desired, then a third more active metal must be added – a Sacrificial Anode. The most common metal is zinc although magnesium and aluminum are also used. This active metal becomes the anode for both metals. In the example below, the zinc or aluminum sacrifices itself to protect the other two metals, hence the term “sacrificial anode”.
On your boat these sacrificial anodes will protect the aluminum outdrive from corroding away. Without proper protection your outdrive could look like this:
For your boat these anodes come in three common forms – zinc, magnesium, or aluminum. Zinc can be used in saltwater or heavily polluted waters; magnesium can be used in fresh – but NEVER in salt or brackish water; and aluminum, which can be used in ALL environments and last up to 50% longer. This begs the question of course, how can an aluminum anode protect my aluminum outdrive from corroding? The answer is the aluminum anode is composed of an aluminum alloy that is more anodic than the aluminum in the outdrive.
Which Anode Material is Right for Your Boat?Zinc Anodes
Zinc is the most common material used in saltwater - like boating at the Jersey Shore or the southern end of the Chesapeake Bay. When used in freshwater, Zinc anodes can form a coating after only a few months of use. This coating can stop them from working. It is a good policy to change them regularly, even if they look OK. Remember, if an anode doesn’t wear away it is NOT working!
NavalloyTM (Aluminum) Anodes*
The Aluminum alloy used in anodes is very different from normal aluminum. It includes about 5% zinc and a trace of Indium, which prevents the build up of an oxide layer.
Aluminum alloy anodes provide more protection and last longer than zinc. It will continue to work in freshwater and is safe for use in salt water. Aluminum is the only anode that is safe for all applications. Use these when boating in the Delaware River near Philadelphia, the northern parts of the Chesapeake Bay, or acidic lakes like Lake Wallenpaupack.
Magnesium Anodes
Magnesium is the most active metal on the galvanic scale. It can be used in freshwater, but care must be exercised. Magnesium can over-protect aluminum hulls or outdrives in salt or brackish water or even polluted freshwater, causing paint to be lifted with resulting corrosion. Even a few hours immersion can cause severe damage. Many boaters on Cayuga Lake in New York State are switching to magnesium for extra protection.
You have now taken the time to protect your boat properly. You tied your boat up in the slip - ready for a season of boating - proud that you have taken the right precautions regarding galvanic corrosion. However, is the boat tied up along side of you protected? If not, why should you care?
Connecting into shore power connects your ground to neighboring boats. If those boats are not protected properly by suitable anodes, your boat will be protecting both yours and theirs resulting in a rapid wearing of your anodes.
Other factors that affect corrosion are pollutants in the water, salinity, temperature, and the presence of stray electrical currents from incorrectly wired or insulated electrical equipment onboard your boat.I hope you found this explanation enlightening and maybe even a bit entertaining. A little basic knowledge about corrosion will ensure a long and happy relationship between you and your equipment.

Propellers: Stainless or Aluminum

Both types of material have advantages and disadvantages and some engines will really only perform well with one material or the other. A small horsepower engine (a 4cyl. sterndrive, for example) really doesn’t create enough torque to spin a SS prop as it weighs considerably more than an aluminum prop. The potential gains of the SS are negated by the fact that the engine can’t spin the prop fast enough. On the other hand, a big, high horsepower monster engine will all but require the use of a SS prop to be able to handle the high torque that the engine creates. The blades of an aluminum prop will actually deflect under the demands of engine’s higher torque, thereby rendering it much less efficient – possibly useless.
An aluminum prop has a lower initial cost and is usually less expensive to repair. However, it can also be damaged easier. While a SS prop is more expensive to purchase, it has a much longer usable life. An aluminum prop can be damaged quite easily by debris in the water or certainly by hitting the bottom; a stainless prop will more than likely chew right through sticks and other debris and not even think twice about it. It’s even possible for a SS prop to survive a light hit against rocks. A benefit that most boaters will appreciate when using a SS prop is faster acceleration, improved throttle response, more pulling power and increased fuel economy. But again, these benefits can only be realized when the engine has enough power to spin the prop efficiently.Hitting something underwater brings up another point. What about the “shockwave” that is created by the hit and sent up through the driveshaft to your engine? Because an aluminum prop is made of softer material it will take the brunt of the hit, although it more than likely will be damaged beyond use and possibly beyond repair. A SS prop may very well survive the hit unscathed, but could send that shockwave up to your engine. However, most propellers have an internal “shock absorber” to help with this.
In the end, talking to a professional or using something like Mercury Marine’s online Propeller Selector will more than likely help to make your decision easier.
One last note: If your prop has any signs of damage – rough edges, bent blades, chips/gouges, etc. – get it repaired ASAP. Even just the tiniest amount of damage will cause the prop to be out of balance and when it is spun at thousands of RPM’s that will translate into “bad vibrations” being sent to your engine (the “shock absorber” will be of no help in this situation). Call or visit your local marine dealer or repair shop and ask about a propeller repair service.

Philly, via the Delaware River
you may wonder the same thing. Well, just sit right back and you'll hear a tale, a tale of a fateful trip. OK, so maybe it should be a tale of a not-so fateful trip…There are actually quite a few places to trailer a boat to that are close to the Lehigh Valley. There are many local lakes and even the Jersey shore is not that far away. However, something that often gets over looked is the Delaware River. Typically, my family and I will make 2 or 3 trips a year to Neshaminy State Park – it is only about an hour away from Allentown, just a short distance off rte. 276. They have a very nice boat launch with 6 lanes and it drops into deep water. In fact, they have two launches, but the free one is much smaller and launches directly into the river. If you are boating in anything other than small, aluminum boat, take my advice and use the pay ramp. The small ramp is muddy and you are launching directly into the river’s current. The pay ramp is well worth the money.
Once we get on the river, we usually head south as Philly is only a 30-minute boat ride away at that point. The main point here is that we are going into Philly by boat! It really is a beautiful ride down the Delaware and once we get there we can buzz up next to the USS New Jersey –
Get out there and make some memories!
Enjoy,

Some Tips to Discover Your Own Boating Adventure
How about you? Have you given any thought to how boating can be a part of the warmer weather ahead? Many people will immediately conjure up images of racing up and down the lake pulling skiers and tubers all afternoon. While that can sure be loads of fun, why not consider including your boat into other fun activities as well?
Here are a few tips to get you started. For instance, why not book a dinner cruise date with your significant other – reservations for two at the best table overlooking the water, your boat! Pack a picnic meal and enjoy a beautiful sunset while gently anchored in a secluded cove. Or better yet, fire up a grill mounted right to your boat and create a lakeside barbeque. Afterward enjoy the peace and serenity of a moonlight cruise. Life on the water takes on an exciting feel once the sun goes down. 
If the two of you cannot easily escape from the rest of your clan, then take them along and reconnect! Use your boat as your personal waterfront estate. Find a cove, throw out the anchor, and spend an afternoon swimming, fishing, laughing, and just plain enjoying each other’s company. Togetherness is the only option in the confines of your boat.

Create your own vacation cruise and take a trip by boat. See new sites from an entirely new prospective this year. Frequent visitors to our blog have most likely read my entry about our summer boating trip last year. Spend an overnight, a weekend, or longer traveling by boat. There are always new ‘ports of call’ waiting to be visited.
Include your boat in your plans this summer and discover your own boating adventure. The possibilities are endless.
Have some ideas that you would like to share? Leave a comment below and let us know how you are planning to use your boat this year.

Onboard Weather Forecasting

Changing weather conditions can convert what was a delightful day on the water into a real challenge. Forecasting what weather you will encounter is one of the top priorities for safe boating.
Should we go out? When should we come in? These are important questions, but some fundamental understandings of the weather can help you make these decisions. That’s what this seminar is all about.
While not a course in weather, this seminar explains how just using your own senses can help you determine what conditions you will encounter where you are.
By all means, a forecast is important. It will tell you what weather systems are headed your way, but they are challenged to tell exactly where and when conditions will change. Add your own observations and you have an extra edge. Add a couple of instruments and you can verify your observations. The seminar explains weather systems, how to understand clouds and their changes, using changing wind direction, temperature, and pressure to hone in on emerging weather fronts. The seminar includes the McGraw-Hill Onboard Weather Forecasting waterproof Captain’s Quick Guide to take aboard your boat.
Join us on Thursday, April 29th, 2010 from 7:00pm to 9:00pm for this fun, interesting, and very useful course.
Instruction is FREE. Course materials are $21.
Seating is limited so please reserve your seat today by calling us at 610-433-1606 or email at ted@petersmarine.com.
Boat Handling under Power
Do you know what is the best way to approach a dock? Now, what if the wind were blowing or the current was pushing your boat, would you be confident of how best to handle the situation?We all like to think that we are the master of our domain - the Captain of our ship - but sometimes a little extra knowledge can go a long way to improving all of our boating skills. Even experienced boaters will walk away from this course with an increased confidence.
Join us on Thursday, May 6th, 2010 from 7:00pm to 9:00pm for an instructional classroom seminar on how to depart and dock under a variety of conditions as well as all about trimming a boat while underway. Seminar materials include a waterproof USPS Captain's Quick Guide.
Instruction is FREE. Course materials are $25.
Seating is limited so call us today to reserve your seat at 610-433-1606 or email us at ted@petersmarine.com
Using VHF & VHF/DSC Marine Radios

Learn the proper use of VHF radio communication.
Join us on Saturday, March 6th, 2010 from 10:00am to Noon for a relaxed and informative instructional seminar on the proper way to communicate via VHF radio. Everyone on board should be familiar with this important piece of safety equipment.
Instruction is FREE. Course materials are $25.
Seating is limited so call us today to reserve your seat at 610-433-1606 or email us at ted@petersmarine.com
VHF radio is the mainstay of coastal communication and essential for emergency communications. Digital Selective Calling (DSC) is rapidly becoming a reality as more Coast Guard Rescue 21 System operations go live. Currently, the mid Atlantic coast is operational with DSC. The Gulf region will be operational early next year and all Coast Guard Cutters will be DSC equipped by next year.
DSC vastly simplifies and improves rescue and routine call signaling – making it easier to make a call while the system frees up Channel 16 for essential communications. However, you need to know how to use it. This seminar answers those needs and explains basic VHF operation. A CD is included with a DSC Simulator that allows you to practice on your computer at home. A handy waterproof McGraw-Hill Captain’s Quick Guide Using VHF is included with essential information that you should have aboard, which will explain to anyone on your crew how to use the radio.

How to Use a GPS - Seminar
GPS has become a common tool for navigation. However using GPS on the water is distinctly different from a moving map display in your car.
This seminar explains the principles of waypoint navigation which you will use. It then shows you how to relate the GPS to your charts which provide essential information about what is around you.
The seminar also shows you how to operate your GPS – what the buttons do, what the screens show, and how to access the functions you need. A handheld GPS is used as the demonstration model, but all GPS receivers function similarly. By the time you have completed the seminar, you will be able to store waypoints into your GPS, activate them for navigation, and use GPS to keep you on a safe, pre-qualified course of your choosing.
You’ll also get some tips for choosing a GPS if you don’t currently own one.
Participants will receive a copy of the USPS GPS Guide and a waterproof McGraw-Hill Captain’s Quick Guide Using GPS to take aboard to remind you of the steps, or to show another of your crew how to use your GPS.
Where: Peters Marine's Boating Safety and Skills Classroom, 1402 Union Blvd, Allentown, PA
