I have never been in a race. Sitting on a rail looking like a moron is absolutely not my kind of fun either. So my experience in how to attract more boats to join is limited. However, I do know what makes the world turn.
Providing some eye candy will help. If the club is to provide two young babes for each captain, I am sure you will plenty of boats will join. For me, I probably will move to MN and buy a boat to race in your club.
Even in this most conservative sailnet forum, members often flock to the thread that are originated by a member with a female name or picture. They offer lot of answer, discussion, help, phone number, and meets. LOL. Not sure why, but it happens all the time. Unfortunately, most these member are married, but I guess that they can still look, read the menu without ordering the candy.
I will be available for further consultation..... LOL
