Sail Area Math by Jim Michalak BACKGROUND
Sail Area Math by Jim Michalak BACKGROUND... If you look at the picture below of the sail rig of Mayfly12 you will see on the sail some (fuzzy) writing (that didn't scan well) that says "55 square feet" to the left of a small circle that represents the center of that area (honest). Fig 1 The center of that area is often called a "centroid" and you will see it is placed more or less directly above the center of the leeboard's area. That is very important. As you might imagine a shallow flat hull like this with a deep narrow leeboard wants to pivot around that leeboard. If the forces of the sail, which in a very general way can be centered at the sail's centroid, push sideways forward of the leeboard, the boat will tend to fall off away from the wind. You should be able to hold the boat on course with the rudder but in that case the rudder will have "lee helm" where you have to use the rudder to push the stern of the boat downwind. The load on the rudder will add to the load of the leeboard. Sort of a "two wrongs make a right" situation and generally very bad for performance and safety in that if you release the tiller as you fall overboard the boat will bear off down wind without you. If the centroid is aft of the leeboard you will have "weather helm", a much better situation. The rudder must be deflected to push the stern towards the wind and the force on it is subtracted from the load on the leeboard. -

Topsail Gaff Cutter Rigged Bolger Nymph
Topsail Gaff Cutter Rigged Bolger Nymph Rick Campbell July 2010 This charming little boat needs some explanation, as she is not the novelty craft she first appears. The rig and hull were carefully selected to fill a unique niche. Some background will help you understand my choices--and why this is an interesting craft to study but not likely one you will want to duplicate. Feel free to skip directly to the “Restoration” and “Sail Rig” sections. I am a designer, but usually not of small craft, and I have spent my life in and around boats and the arts. Sailing is clearly an art form (there are more paintings of sailboats than symphony orchestras), and I think amateur designs can be more creative and interesting than the usual professional craft commisioned by a wealthy amateur yachtsman. Phil Bolger’s old Small Boat Journal Cartoons are delightful examples of some amateur’s hare-brained concept sparking the imagination of a gifted boat designer. I also believe that widespread use of the scientific method by amateurs is the key to human-driven evolution. The Scientific Method: 1. You have an idea that differs from common knowledge and practice 2. You figure out a way to test that idea 3. Your experiment reveals merit and flaws in the concept 4. You use what you’ve learned to modify the original idea/design Reading and habitual use of the scientific method are keys to furthering your own education. Reading takes you on previously traveled paths, and the scientific method takes you further. Along the way you discover stuff you didn’t even know you didn’t know. -

Sailing Course Materials Overview
SAILING COURSE MATERIALS OVERVIEW INTRODUCTION The NCSC has an unusual ownership arrangement -- almost unique in the USA. You sail a boat jointly owned by all members of the club. The club thus has an interest in how you sail. We don't want you to crack up our boats. The club is also concerned about your safety. We have a good reputation as competent, safe sailors. We don't want you to spoil that record. Before we started this training course we had many incidents. Some examples: Ran aground in New Jersey. Stuck in the mud. Another grounding; broke the tiller. Two boats collided under the bridge. One demasted. Boats often stalled in foul current, and had to be towed in. Since we started the course the number of incidents has been significantly reduced. SAILING COURSE ARRANGEMENT This is only an elementary course in sailing. There is much to learn. We give you enough so that you can sail safely near New Castle. Sailing instruction is also provided during the sailing season on Saturdays and Sundays without appointment and in the week by appointment. This instruction is done by skippers who have agreed to be available at these times to instruct any unkeyed member who desires instruction. CHECK-OUT PROCEDURE When you "check-out" we give you a key to the sail house, and you are then free to sail at any time. No reservation is needed. But you must know how to sail before you get that key. We start with a written examination, open book, that you take at home. -
