Hi Alan,
Can't remember which Brinks boat Robin was on, but it had a planing hull and did the cha cha cha across the rivers in a crosswind. I have to say, that was one thing that surprised me about Broadway, even in those very strong to gale force winds, for a bathtub it stayed remarkably straight! So next time, rebuild a bathtub , well you WILL be older by then!
Iain.
