You would have trapped me using yummy tuna and canned mackeral.
Even if you were single, that is weird that someone would invite you to go sailing for a first date. Which reminds me of a time I took my prior girl friend out on my sailboat for the first time. It was probably around our 6 or 7th date and as I was perfoming the difficult and tricky job of backing my boat into its slip, she decided to ask me if I beat women. Such an "off the wall" type crazy question like that totally threw off my concentration and I had to make a second attempt at mooring the boat.
