Which anodes?

[mlines]

A quick search of the forum seems to have the odd discussion item but no real conclusions.

We bought our first boat this summer (Bayliner 185 Bowrider) and have had a good time dropping it in and out of the water at Poole and Wargrave/Windsor.

Originally Poole based, it has seawater anodes fitted, but looking at what we have used it for this year it has been almost 50:50 seawater/freshwater.

Being nothing more than a high powered soapdish it is not kept in the water. It is washed down and kept on the trailer at Wargrave.

Is there a best option for an anode kit, each venture into the water is probably a maximum of 4 or 5 hours with a freshwater wash down at the end.

Have a look at this site, it will answer all your questions.

In short it wont really matter as your boat is not in contact with the water long enough to cause problems. That said, as you use in both fresh and salt waters you should have aluminium fitted.

Yes see MG Duffs website in particular THIS PAGE
Trouble is there is no real way of catering for a craft moving repeatedly between fresh and salt water,

Aluminium may be the best choice although still not suitable for continuous fresh water use.

BUT as said for a boat not kept afloat there is hardly any need for anodes esp for only a few hours afloat, except perhaps on outboards and overdrives etc. in salt water.

Replace your anode(s) when more than half eaten away. At present rate of decay how many decades/centuries/millennia do you think that will take?
