Blackmagick Sails

Try a little kiwi magick on your boat!

The above air flow and pressure diagram shows the highest flows and pressure areas in red and blue. From this we can see that the areas near the head of both sails have the highest numbers and therefore the most movement of air. It is important then to keep these areas of your rig clean aerodynamically. It might also suggest that these area's should not be to full or the air flow might have trouble following the sails camber, if it should break away it could  stall out the sail at this point and you will loose valuable drive! If you look carefully you will see the area between main and jib by the mast is coloured orange. This would suggest this area has the slowest moving air of all, making a fallacy of the slot between main and jib having the highest air flow. If this is the case the slot between main and jib may not be quite so important as some tend to think! It suggests to me (looking at the air flow) that the jib is far more important and doing more work than the main at this point of on the wind sailing. Food for thought at least I should think.

This is a A/C yacht out of Canada, a beautiful looking yacht, if you love sailing and yachtin, R/C sailing can give you all the thrills of the bigger boats at a fraction of the price, including the fun of designing and building your own if you have a mind to. And the racing is of the higest level, there are no easy wins in R/C yachting!
