You may also wish to check the 505 Registry, which has information on some specific boats, when we have it.
When comparing the number of boats built in different years, consider what the longevity of the average 505 was that year. Early 505s - FRA 8, FRA 21, FRA 38 and some of the other early 505s notwithstanding - did not normally have very long competitive lifespans. The competitive lifespan of 505 is much greater now (and has been for some time) than it was in the early years, and the frequency with which 505 sailors buy new 505s has decreased accordingly.
