To search sailnet forums for a specific phrase, google it like this:
"mast stepping" /site:http://www.sailnet.com/forums/
Without the double-quotes, the search finds *any* of the words (even parts of words, e.g. 'step' from 'stepping') in your phrase; with them, the search looks for the *exact phrase*. You can fine tune the results once you see how broad-meshed your original phrase is. Basically, the more words in your search-phrase, the fewer results you get.
I've always admired the old Norfolk Wherry* mast rig. Counterweight at base of mast, beefy tabernacle setup, one man on a manual winch. They aim at the channel under the bridge, drop the mast as they get to the bridge, raise the mast as soon as they clear it, all without losing any time or tide, or inconveniencing vehicular traffic, or paying bridge tolls. Clever folk, those English.
