Kerry, The listserve is alive and well! I for one have been busy
hauling and preparing the Mighty Quinn for the winter. This always is
an expensive and time consuming exercise up here where the water gets
"hard" for 3-4 months! At the same time, it is an opportunity to
carefully check out the bottom of the boat.... including the area on the
keel where I grounded hard on a reef in heavy weather (I normally would
sail right over, but I hit the reef in a trough of a wave at about 7
knots). I took out a good slice of lead at the leading, bottom edge,
which will require some significant work. So, I now am considering
whether I should take this opportunity to modify the keel with the Mars
torpedo. Has anyone on the list actually done this?
