Pitching
Bob: What I noticed when our Swing Keel C-22 was beside our friends Winged Keel C-22 and a motor boat put a wake in front of us that both of us had to go through was that the winged keel pitched when it went through the wave much more than our boat. By pitching I mean that the bow went up and down much more than ours did. I remember this vividly because my son was at the tiller of the winged keel boat and I remember him looking at me thinking what in the world is this all about? I believe that this is caused by not having the ballast deep enough into the water, sort of like having a short pendulum that oscillates faster than a long pendulum. I wrote about this on the C-25 forum, (we are currently looking for "just the right" C-25), but those guys disagreed with me, and several of them have had both swing and winged keel C-25s. They did mention that they sail on lakes, so they might not get long tacks.Our C-22 does outpoint our friends C-22, so much so that racing across the Chesapeake, around 11 miles, we can almost loose her, and she used to race. On the issue of salt water "eating away" the keel pivoting parts, I have written about attaching zincs to the keel several times on this forum. I have 2 sets of zincs on my keel and I replace one set every year. The last time I took the pin out of my keel it looked perfect, and the hole on the keel wasn't enlarged either. My boat sits in slightly brackish water every summer.Aldo
