Hi all, I recently visited the Olympic Peninsula in Washington and while there took in the Wooden Boat Foundation headquarters. The newest album to the Photo Site is a pictorial review of their chandlery. Hope you like the photos... Bill http://www.funtigo.com/MSOG?b=272153&c=1789789&p=start

Hi Christian, A new M-15 will come with loose footed main and with sail slugs. In my opinion both have made sailing much easier. Not only for raising the main and reefing but also makes sail shape easier to control. Such as loosening the outhaul to make the sail more efficient on a down wind run or tightening the outhaul for spilling the wind when it picks up. Hope you are able to go ahead with your plans for a new boat. Sure makes it easier when the changes you would have made to an older boat are included with the "new and improved" model.

I just try to follow best practices per the galvanic chart on boat stuff. Copper would make a better ss to al conductor instead of insulating them on mast parts. But who knows (I sure don't) how much or how fast the copper would make a difference. All bets are off when I work on cars, mcys and airplanes though. I just replaced a head gasket on a Honda Civic and used aviation copper gasket sealer. I have no idea why dissimilar metals are less problem on autos than boats...boat diesels have sacrificial zinc sticks that go in the crankcase and I've never heard of car engines having them.

I use heavy copper anti-seize on my motorcycle and have for years. I assume the combination of these three metals in an H2O environment is what you don't like? So you'd be in the tef-gel camp, right? t Tom Smith & Jane VanWinkle M15/345--Chukar M17/064--Unnamed

Use magnesium as the freshwater sacrificial with aluminum and zinc in saltwater. Thread sealers with copper will make three different metals (al, ss, cu) and more chance of electrolysis than just ss and cu.

In the list below, it is my understanding that the metals at the bottom of the chart are the ones most susceptible to corrosion. That's why silicon bronze corrodes so little, and why zinc is so useful in protecting other metals. The zinc corrodes and gets used up instead of the stuff you're counting on. Examples of this are the "sacrificial zincs" which are put on outboard motors to protect them, and therefore must be replaced from time to time.

Although galvanic action is a problem faced primarily by boats used in salt water, freshwater boaters cannot be totally ignorant of the problem: not all fresh water is chemically pure, and water that is even slightly brackish can set galvanic action into motion. The following is an electrolytic table which rates metals from "most noble" to "least noble." In non-pure water current will flow from the less noble to the more noble metal, and in the process, the less noble metal will be destroyed. Metals close together in the table can be used together. Metals far apart cannot. Yellow brass, for example, is composed of zinc and copper. Over time galvanic action will erode the zinc. For that reason brass screws, valves, etc. would be useless in salt water. mercury monel nickel bronze (silicon) copper brass (red) bronze (aluminum) gun metal brass (yellow) bronze (phosphor) tin lead steel (stainless) iron steel (mild) aluminum cadmium galvanized iron and steel zinc magnesium Regards, Diane Kerr High Barbaree M15 #625

What a priceless name! When I read stuff like that, I'm reminded once again that there's quite a gulf between me and most of humanity. Maybe you could name it Carmella, and use a static sticker ( Knowledge) to put on there when you're sailing solo.... Oh, the blasphemy. Steve Tyree STILL trying to finish his concept boat At least it has a name that's sticking "Huck Fin" If you saw the boat, you'd understand :) In a message dated 8/3/2005 9:08:22 AM Central Standard Time, steve(a)appliedphotonics.com writes: BTW, the boat is a unique Carmel/butterscotch color. I suggested to my wife that we name it Carmel Knowledge. I just got the "look" in return. I think you know what I mean.
