Really depends on where you are. If tied up in brackish or backwaters, a
few days and you'll get growth, a week and you'll need scraping. Give it a
few weeks and you'll be able to harvest something. If in open waters, a
week's fine.

Hello.

What would a week in salt water do to the bottome of a new fiberglass
boat.
Mine is treated with paint and came from a marine owner. My friend's is
brand new, only fresh water usage with no protection.

Thanks,

Greg
