RE: boating question
Who else on the internet is going to know his capabilities other than his dad and if you have to ask then I say hell NO!!! You don't provide a whole lot of information on his skill level or the lake or the activity on it. There are too many inexperienced people on the water ways and if he doesn't have proper certification on boating than if an accident were to arise than it would be a liability issue as if he has had proper training in boating. If he doesn't have the boating certification then HELL NO. Bottom line. Just because you showed him how to trailer a boat doesn't mean he can handle the conditions if they change on a lake.
Theirs more to boating than throwing the kids a set of keys to the boat.
