If you're only leaving the boat in the water for a few days, or a week at a time, what about using a hull protector like Easy On Bottom Coating? They say it's good in low fouling waters, but it's better than no protection at all.
It's not a bottom paint. It says it's a soft wax coating. I saw it on the West Marine site: http://www.westmarine.com/webapp/wcs...roductId=20267

I'm planning on putting in a lift next year, just cant swing it now, So bottom painting is not an option. As said in a previous post "poor resale value". That Easy on Bottom Coating wax sold at West Marine sounds good. Has anyone tried it?

Biggest problem after barnacles is electrolysis. Do some reading about that. I lost two outdrives in less than 6 weeks because boat next to me had 12V lines in water under boat and an automotive battery charger. I've gottne electrolysis over a weekend --zincs pitted--because of "hot" boat or lousy ground in marina wiring.

I've got dual Volvo QC mercathod systems, galvonic isolator, zincs everywhere, major bonding system and in some places can still see problem in some places. An old rag-boater driend swears by those big zinc fishes you hang from boat and ground to block.

In the past I've left boat in for 4 years with no problems--so it's location specific.

I plan on running the boat to a friends house on the south shore of LI.
The boat will be in the water for a week.
He keeps his boat on a lift, so i can pull out once or twice to wash the bottom.
I will also be running the boat every two to three days, so it won't just be sitting.
Any opinions on this type of use? I think I should be ok.

I'd worry a lot more about electrolysis than barnacles. Zinc everything that isn't stainless or bronze. Isolate dissimilar metals. Put electrical tape under drive trim indicators if they're stainless , the cylinder is aluminum and they are clamped together.

This may be a wise investment.
