If the beer cans are electrically isolated from the boat, then you're good. Of course this doesn't work well in the summer when the lake is 75 degrees.Which is why you shouldn't forget about the beer you hung over the side to cool.

Zinc for saltwaterZincs last longer in freshwater because they don't work in freshwater. A more reactive metal is necessary. In freshwater use magnesium or aluminum anodes. Aluminum works in fresh and salt water.
You can embolize in just a few feet of water, certification or no. Six feet is plenty deep enough to kill you, if you don't know what you're doing. Advising that SCUBA safety training isn't necessary for people using SCUBA equipment is pretty foolish, IMHO.I did get certified but reall y don't think for the depth under your boat is needed and yes some will disagree.
Zinc will protect Aluminum if the water conducts electricity. Nothing protects in "Lake Distilled Waters" either.Zincs last longer in freshwater because they don't work in freshwater
From left to right, zinc anode, aluminum anode, and magnesium anode. All from the same boat in fresh water (Lake Ontario). The zinc anode was on the boat for many years, the aluminum for one year and the magnesium for 2 years.Zinc will protect Aluminum if the water conducts electricity. Nothing protects in "Lake Distilled Waters" either.

It is a 5 minute task for a diver. Need a small bag for the new zincs and a tool to screw the zincs tight. My diver uses a T driver with the proper hex drive. It is a simple task.
Holding your breath you could probably do it.
Or there is the ancient mariner route and keelhaul a young virgin to accomplish the task... opps that is wrong.
Move your boat to shallows. Anchor and let tide go out. Step out on to sand beach change the zinc. Wait till tide comes back in. All done. Be sure you have enough beer. It's going to be a 12 hour project.
I want the bottom cleaned too... and to look at the thru hulls.Gene, You can get a diver to do it for less than a haul out. PM me if you need a number.
You can buy Hookah systems for 1200 and up... with 2, 60 ft lines, weights, mask for around 2000. I prefer the electric as opposed to the gas... they can also be powered by your gen or a portable Honda at sea.Didn't say it was cheap. But considering the cost of SCUBA certification and equipment, maybe it is. Then you can rent yourself out and make some money back.
Hagar, that looks like an interesting and very reasonable cost option. Can you give me the particulars of the compressor and regulator? I came across a Porter-Cable oil-less compressor for only $99 but perhaps it needs to be higher PSI? In any event seems like a useful item to have aboard. Won't help me this season but something to consider later. ThanksI have a DIY hookah made with a Porter-Cable oil-less pancake compressor, 25 ft of 1/4" hose and a regulator I bought on Craigslist. Works just fine for working on the bottom of the boat. The compressor runs fine off the 2500 watt inverter if away from the power supply. With this setup (and a wet suit) I still pay the local diver $60 unless it is summer! Figure it might come in handy some time if we get wrapped up in a crap trap line.
That should have plenty of pressure for the purpose.I came across a Porter-Cable oil-less compressor for only $99 but perhaps it needs to be higher PSI?
So you won't have oil in your breathing air, just whatever particles of metals, plastics, and polymers that a tool compressor spits out!Hagar, that looks like an interesting and very reasonable cost option.
I built my own simple system a few years ago.Mantus (the anchor people) make a perfect SCUBA set up for us sailors. It is relatively inexpensive and only has a 20 minute capacity, but for replacing anodes and quick bottom cleanings it is perfect. However, it is necessary to get he full SCUBA certifications. Alternatively, a floating hookah system would enable a skipper to stay underwater long enough to do the same.
Assuming the diver is in business and that you are satisfied with his work, why would you not simply plug his business here for all to see? Do you think he'd object to a little free advertising? Do you think his business needs to be kept a secret from the rest of us?Gene, You can get a diver to do it for less than a haul out. PM me if you need a number.
I can't imagine a yard in this country even agreeing to try something like this.The lift didn't quite work today. After they lifted the stern clear of the water, the crane started to slip - the boat was just a bit too heavy for it. Thankfully I wasn't lying on the wooden raft under the boat. It goes to show how a seemingly simple operation could kill you.
