I'm gonna disagree with this one. It might be so for some people but there is a whole lot of weight (physically and psychically) attached to a bigger keelboat. I can capsize a laser all day with a smile on my face but sitting on the windward side of our boat with the rail 6 inches above the water is in no way the same experience.Big fan of learning on small boats. Beach cats and dinghy's will conquer fear of keel boats.
We've learned not to sail in anything over 10 knots the first day we are back on board (we are usually away from the boat 8-10 months at a time). A couple of days and the nerves settle in and we are back to sailing in 15-20. But I have to say we still can't get over gusts. A 20 knot gust in 15 knots scares the crap out of me (us). Every. Single. Time.
