This discussion of engineless sailing has reminded me of something I witnessed back in the 1980's when I worked on The Opua wharf in New Zealand's Bay of Islands. I was running a yacht charter company at the time. The Opua wharf has very strong tidal flows across the wharf and we used to have a lot of entertainment during the busy summer season watching the catastrophes at this difficult wharf by boat operators who did not know their stuff. I remember an American sailor named Bill Sellers who sailed an Atkin 'Tally Ho' design and was resident in New Zealand but went off cruising up to the Pacific islands each winter. Bill had an engine, but apparently removed the propeller for ocean crossing so as to maximise the speed of his boat.
Anyway one year I witnessed him arrive from overseas and come into the Opua wharf to clear Customs. He approached the wharf under headsail only, and then when about 50 metres from the wharf dropped his anchor and let the chain run out. He dropped his sail and drifted beautifully alongside the wharf. totally calm, not rushed, and very professional. Several hours later when he had completed Customs formalities and it was time to leave he cast off his dock lines, casually winched in his anchor chain till it was up and down which pulled the boat away from the wharf, hoisted the headsail again, pulled up the rest of the chain and anchor, sheeted in and sailed away from the wharf. No fuss, no bother, and certainly no shouting at his crew.
After all these years that very relaxed and competent act of seamanship without the use of an engine still stays in my memory.
