I pay for the boat and tell everybody what they owe for that. I also pay for all the provisioning. We all try to pick up different dinner checks, grocery bills and what not. We log it all into a little notebook and add it it up based on the couples. I've never asked anybody to pay more as it usually ends up fairly even..we're all friends, if I thought somebody wasn't/wouldn't paying their share, I wouldn't invite them. That said...I'm really looking forward to going with just my wife again. It would be nice to just do what we want to do. It's been quite a long time since we've done that.
