So has anyone ever taken there bike for a boat ride? I mean a large passenger/car ferry.. People do it all the time I know, but Ive never paid much attention to whether they tie down or what? Its a 300+ foot boat so pretty stable but there can be a good roll some days...Whatd you do? Stand there and keep an eye out? Its a 75 minute crossing! Tie down and forget about it Im thinking? Any experiences on here ?
