According to my trusty, dusty, Maplin indoor/outdoor thermometer, which I believe to be reasonably accurate, the temperature here in Norwich reached almost 20˚C this afternoon.
I have another in/out thermometer on Jubilee, with a useful max/min function, but its two sensors don't agree with each other. Putting the "remote" sensor in the same place as the main unit the two temperature readings differ by 2.0˚C.
Boating weather? Definitely. But so also is 0.1˚, rain, sleet, snow ... A year ago it was freezing, with snow lying in shady spots. This was 6th April 2013 on the Trent.
