I enjoy having non sailing guests on my boat. Most just want to go for a boat ride and enjoy a day on the water. I try to generate some interest in how the boat sails but if I see none I just drop it and do my own thing, which is to enjoy our guest, sip on a "tinny (aussie for beer)" but always keeping one eye on the sails. On the other hand, if I do see some interest from the folks as to how the boat works I encourage questions. Oddly, but not surprisingly, most interest comes from the gals. I guess guys are too macho to ask questions. Some guys tell me they have sailing for 20 years - I've been playing golf for 20 years and up until a while ago I never hit the ball to the same place twice!! - then they ask me how the topping lift is used to trim the main.To further the interest in how the boat works I ask the gal if she wants to drive the boat. Most are reluctant but when I tell them I'll be standing right next to them they go for it. With many of them they like it so much I can't get the wheel back!!Here are some of the questions that are commonly asked. How would you answer them?Is the only use of the halyard to raise the mainsail?How do I know when the halyard is properly set?What is the top batten used for in addition to stiffening the sail?Is the front part of the sail (luff) set differently for upwind and off wind and what are the settings?What is the main use of the traveler and what is its normal range of motion?What do telltales indicate?Lets say there are quests on your boat and you have given the wheel to to a gal and she asked you these questions how would you reply. Remember to keep the explanation simple!!
