Wnen a sail boat is running a pennant on the mast would point towards the bow. This would hold true even if you started to come about (untill you were no longer running). Of course it would point towards the stern if close hauled. How about a quickie ? Which is the longest U.S. coast line ? Rick ...!cybvax0!fbp "A likely story. I don't believe a word of it."

Sure it would; and the boat would still be running. Boat sails are made so that when the wind fills them up, they create an air- foil. This allows them to run without having the wind to their backs. The boat must cut the wind at an angle but not directly into the wind in order for this to happen. To move in the general direction of the wind, the boat must "jive" (in other words, make a zig-zag pattern running the boat to a point to the right of the source of wind and then to the left). This causes the boat to travel a greater distance, but it is still moving against the wind. There- fore, jiving the boat into the wind causes the pennent to point toward the stern (not directly pointing at the stern {unless during a jive}, but more towards stern than bow. > Which is the longest U.S. coast line ? As for the longest coast line, I would guess the California, Oregon, Washing- ton, Alaska, Hawaii (Pacific Ocean) coast-line.

Sort of like skating on the apparent wind. To get it to work wouldn't you have to pump the sail a bit as you came about ? I'll try this next chance I get. > >> Which is the longest U.S. coast line ? > >As for the longest coast line, I would guess the California, Oregon, Washing- >ton, Alaska, Hawaii (Pacific Ocean) coast-line.

Guess #1: Alaska.
Guess #2: Little America.

A while ago I posted the Sail boat pennant question to net.puzzles. (Which way should a pennant on a running sailboat face, the bow or stern?) There were many correct answers (bow). However, several people suggested that it would be possable to get the pennant of a running boat to face the stern (or at least away from the bow). This was described as "jiving into the wind" by several people. I have spent many hours trying to figure out what exactly they meant. Could someone enlighten me ?
