row row row yer boat

freezing today while mooching around trying to find something blipworthy.
the River Severn never normally lets me down but it was a pity its such a grey day.
the angle of the photo does`nt realy show how long the boat was. ide say aprox 50ft but im sure there is many a boater out there who would know the standard lengths?
hope the sun shone where you are..
