Sailing single handed is great fun with a livelier performance and more 'strings' to play with. You can always furl the jib and just sail with the main alone. The spinnaker kit is easily added. It is easy to fly and adds significantly to the speed and fun of the boats. The 16 takes a 4hp outboard and the 13 a 2hp.
Motoring can be great fun when the wind has dropped or in the canals of Holland.
Lower a bit of centre plate to prevent skidding sideways. The rowing kit on the 13 works well, the 16 is too broad to be rowed. Use the reefing line to raise the boom over the oarsman's head. Magnificent distances have been rowed by 13s helmsmen in Holland when we all got stuck in a caim a couple of miles from home. Very solid with good attention to detail.
