Experience is good, but a "check list" is absolutely necessary (at least it is for me). There is just something exciting about sailing--but, having so much fun can cause forgetfulness and error.
Another example, yesterday, I pulled into a nearby Marina single handed to visit a friend & his wife (owners of a Trawler), and as I cut power, & pulled the boat to the pier with my boat hook, well, YOU GUESSED IT....no rope to tie up !!! HA. Proof once again, having so much fun can even misplace dock lines.
NO...I dont drink, and wasnt drunk...
All that error is okay -- its all in a fun day of Mac sailing/motoring.
edit add: Last weekend I ran out of gas within my Marina, returning from an afternoon on the water...good thing I had a container with a half gallon on hand...(another check list item)
Before anyone pokes fun, I dont make the same mistakes twice. So, I'm narrowing things down...heh heh
