Still planking after all this time

The end of planking is almost in sight, but formwork is now required. And a friend has offered me his scaffold planks and trestles. Amazingly how help just keeps coming at the right moment.P1040411S

During the mindless recovery of cedar planks it occurred to me that this boat will be doing a lot of shovelling. Lightship (empty) displacement is about 8 tonnes. The boat length is 10 metres. Every time the boat moves one boat length of 10 meters, 8 tonnes of water is moved aside. If the boat is sailing at say 5.4 knots or 10km per hour. it is moving 10km/10m = 1000 boat lengths per hour. AND that is 1000 x 8 = 8000 tonnes of water pushed aside every hour. Or 192000 tonnes per day. For a 300 day GGR that is a staggering  57600000 tonnes!
