Hello David, you have certainly answered my question with that comment, i have just checked the only edition i have seen and it was 1971.
Hi Derek, i wish i had been there as early as your first visit, you must have some fantastic memories, just a few years before my first trip i had to settle with on average about 5 or 6 ships per tide for quite a few hours standing around, my first day there blew me away, cloud 9 after what i had been used to.
