Even if it's family or friends, if they are frequent on guests in your boat do they not offer to help out on any expenses? And if/when they do offer do you accept? If I didnt own a boat and a friend or family member took me out regularly and I got a share in the catch, I would feel extremely uncomfortable f I didn't pitch it. I would insist and if they won't accept I would leave it on their counter when thry are not looking so they have no choice. I was brought up this way. I find it strange that there is a different perspective to how this scenario is viewed. If I go on a weekend trip with my sister or brother or friends, we always split the costs of accommodations if we are renting a cabin or a chalet. If we order in food for everyone, everyone pays their share. This is sitting of costs is also very common with just about everyone I know. If everyone is going on an adventure or an outting and it happens to cost money, no one is ever left paying for everyone else's share. Why is owning a boat and the high costs of running it any different?
