It's both good and bad to have the option to edit the boat names. Personally I don't see big reasons to have that option, but there is a big reason for not having the option. I can promise you that someone will "steal" the identity of another skipper, trying to give a bad reputation. A solution that will satesfy both the urge to have more boat names, and wish to protect against abuse, is to introduce another feature in the race lobby. When you click on a boat name, another field on the screen should be updated with the unique login identity of that skipper. This way a skipper can never hide under false name, but can still use more boat names if he has reasons for it.
PS! Later, skipper stats can also be published that way.
