G Man Posted September 17, 2009 Author Posted September 17, 2009 Since I have found a shipyard that has some stock in the size I am looking for it sounds promising. They have been quite helpful and am confident they have the resources to obtain extra stock without gouging me on the price. Can anyone comment on the "seaworthiness" of the P22? I am getting close to the point of committing to a design and just wanted to be sure that the P22 will satisfy my sailing needs. What is the righting arm? Could this be used for offshore work or are there some mods to be done. I would like to sail in the Dubai to Muscat race at some point (360nm offshore race) or simply not have to worry about picking the perfect weather to go sail. Keeping in mind the conditions here are not that extreme and most people sail production coastal cruisers just fine here. Thanks again for all the input. I suppose I am changing the topic a bit, should I start a new thread? Quote
Designer Posted September 17, 2009 Posted September 17, 2009 G Man, With most things in life you have to give up something to get something. The boat was designed to have high stability at normal sailing angles. If you want a light boat with shallow draft you can't have a high range of positive stability. I have shown the P22 at 90 degrees of heel with the center of gravity at three positions. The calculations were done with 350 # of crew in the cockpit. GC1 is with shallow draft which shows the range of stability to be about 85 degrees. CG2 shows the ballast lowered for a draft of 1'8" and gives 90 degrees. CG3 is with the same draft but without the crew in the cockpit which increases the range a lot Quote
Joe Nelson CS#35 Posted September 17, 2009 Posted September 17, 2009 Not to hijack the thread, but what does the higher sheer do to the stability curve? Not asking for exact numbers, just a general statement. Quote
Tom Lathrop Posted September 17, 2009 Posted September 17, 2009 Not to hijack the thread, but what does the higher sheer do to the stability curve? Not asking for exact numbers, just a general statement. Higher sheer is obviously a positive factor in righting stability. An even greater factor is often the cabin because of its greater moment arm whenthe boat is at or near 90 degrees. Of course, this means that portholes, and hatches must be waterproof or nearly so. For example, while the sheer of the EC22 is pretty low, the cabin makes it very resistant to turning turtle. Quote
G Man Posted September 20, 2009 Author Posted September 20, 2009 Thanks for that Graham. It seems that stability performance would suit the conditions I would be sailing in. Quote
ecgossett Posted March 13, 2012 Posted March 13, 2012 Does anyone have photos, diagrams of cabin on EC22?? Quote
Joe Anderson Posted March 13, 2012 Posted March 13, 2012 You can find photos of an EC 22 including cabin construction at my building blog. http://sundogboatbuilding.blogspot.com/ Quote
Charlie Jones Posted March 15, 2012 Posted March 15, 2012 Don't klnow about the plans, but I've sailed on Southern Skimmer- ain't much interior there Quote
