Tanzer 16 A fast sail in ideal conditions

Tanzer 16 A fast sail in ideal conditions  -- 4.4 km in 30 minutes--no kidding -- June 23, 2016  I dinked around all day trying to get the length of the shrouds just right so there would be enough tension on the roller furling luff.  I had a new hinge made, and that required that I shorten the shrouds.  They were already loose from the last round of "improvements." Finally after three hours of a little less here, a little more there, three different length shackles and some spacers at the head attachment to the mast--it all fit, and I made it to the launch in time for our test sail.  (*See below)

When we left the dock, the tide was low, really low.  The wind was out of the NW at a steady 8 knots. We made it out to Boston Harbor, that's five and a half km in less than an hour.  The current was against us.  We only tacked once to stay in the channel.  The wind just wanted to lift us up--couldn't believe we were that lucky.

Coming back was better. The wind shifted; came out of the SW and WSW at 8 knots--no waves.  We were close hauled all the way, The current was with us.  We turned south at exactly 1800.  At 1830 we passed the Olympia Shoal--4.4 km in exactly 30 minutes.  We were throwing a nice clean wake all the way; add in the current and we were way faster than hull speed.

Sometimes you get double lucky!
























And--by the way--the new sail from Schurr worked well.  Well built--great service.

*It was a lot easier hook up the luff since I use the winch on the trailer to raise the mast.  I had some mechanical advantage so that I could over-tension the mast against the shrouds, hook the Genoa, then back off the winch tension. It was also helpful that I have temporary supports (shrouds) in place as part of the gin pole mast raising process.  It allowed me to disconnect a shroud while I worked on the spacers and still keep the mast standing in good control. Without that feature, I would have needed to raise and lower the mast three or four times.
