Re: How to properly dock your boat?
Not enough info. Mooring can be very tricky and a half-inch error can sink a boat.
Floating docks don't count--too easy!
There are ways to tie up to use the hull shape and current to hold a boat off.
On a serious note: I have been boating will small or inexperienced children (and childish adults) a lot all my life. When I approach a dock or go along side another boat, I say "hands in your laps!" Little ones understand this. It also keeps them from trying to get off the boat early. Otherwise tiny fingers and even whole arms are at great risk.
Also the size of the boat (and conditions) determines whether you can get close enough and use the boat hook (or hands) to pull you in, or whether you need to wrap a bollard or dock cleat. It's good to designate and train, in advance, one person to be the docking assistant. The rest need to stay seated, hands in their laps.
