Re: I'm ashamed...I cheated!
It's common among most sailors to motor up narrow channels. Sadly if you go cruising in a popular cruising ground you'll find that it is common among some "sailors" to motor everywhere.
I personally like sailing up narrow channels, but have even fired up the motor when currents + wind are causing my forward progress to be measured in minutes per meter instead of meters per minute. Short tacking among currents and rocks in a narrow channel is demanding and that makes it fun for me.
I have two dinghies which don't have a motor installed (and I teach sailing on boats without motors). In those conditions occasionally a paddle or oars will be necessary.
