Yep, fabulous book. One of the all time classics of cruising under sail. The Smeeton's themselves, an interesting pair. Seem so very old fashioned today but hey, they came from another time and place.
I'm presuming you've read 'Trekka Around the World' as well ? They do go hand in hand. Poor old Tzu Hang .... her end was quite sad for such a lovely old lady.
