Re: [Cal_Boats] Mast pumping (Mike)

Mike, You replied to my posting of Bill Lapworth's instructions on how to tune a mast with this? WTF? My original post on mast pumping was that maybe it is a good idea to leave the lowers alone. Get a life my friend. I have limited racing, 6-1st, 10-2nd, and 2-3rd, out of 20 only races. The only guy who beats me is a two time national champion in the Express-37 class. I have nothing to be ashamed of. If this wasn't directed at me, then be careful which post you are replying to when you get all high and mighty.

Dear Allen, I respect your racing record and . Never be ashamed of any thing. Shame and regret are too costly emotions to be squandered easily. If I have insulted you I can assure you that is not my intention. Congratulations for sailing in 20 races, many sailors will never enjoy your level of success. My experience is somewhat different than yours. I come to sailboat racing from professional motorcycle racing (Dirt Track) I held a Competition License and raced the Grand National circuit in 1967/1969. Physical injuries put an end to all that. I have raced on SF Bay and the ocean since 1971 in boats from 8 feet with unstayed masts to 80 foot wood M boats(2/3 of a 132 foot J) I raced and sailed New York 70's with a 5 spreader rig. Santa Cruz 70, Mexico, Carribbean, Atlantic, South China Sea. 4 Pacific crossings. 1988 Pacific Cup double handed div. Well I won't go on. I do not feel high and mighty. I chose to spend a lot of time at sea instead of earning financial gain ashore. I have a great life and I choose rather than react to situations that confront me. I would hope others can learn from my time at sea as an able bodied sailor. I have earned my living from the sea and perhaps I seem opinionated at time I see a lot of time wasted at supposition when time at sea would be more benificial to one's goals. I went sailing 2 days last week, I am going again today. I will most likely singlehand and set an "A" chute that I have heen working on. I have installed a 4 1/2 foot removable sprit on the Cal 20 I do keep busy. And thank you for your concern, of course I will be as careful as I can be.

Mike, To be clear, I never did and never would challenge your knowledge, experience, or advice. What did offend me was that I was trying to help the OP who wanted to find the Lapworth mast tune papers and out of the blue you tell me I "didn't have a clew". I am not even the one complaining about mast pump. I guess you didn't like my other posts. Perhaps you don't like the tools I have posted for others to use. So ignore them, don't insult me about them. I am happy you got to go sailing last week. In terms of simulations, one is attached. I have learned a great deal about what is important in specifying this sail by looking at the 3d models as well as from comments by the great people on this list. Besides, I have learned a new skill. I hope you like it. Best to all, Allen On Sun, Dec 20, 2009 at 5:18 AM, mike farrell <ve… [at] yahoo.com> wrote: > > > Dear Allen, > I respect your racing record and .
