Also, I wonder how using a water separating fuel filter would help to protect from the effects of ethanol gas?

This is an article from the Boat US Forum

There's a lot of information on that site and boatered.com about it. Seems like fiberglass gas tanks may be the biggest issue. There's also a lot of worry about water mixing with the ethanol and seperating it from the fuel. In addition to the obvious problem of water in the fuel, taking out the ethanol will reduce the octane. Finally, ethanol may cause trouble with old rubber fuel lines. It remains to be seen how bad these possible problems really turn out.
