As a member of two of the six clubs which enjoy heavily discounted rents at the expense of the public ('Public picks up tags for exclusive clubs,' South China Morning Post, October 26), I was fascinated to see that the market value of the Royal Hong Kong Yacht Club had been estimated without the actual size of the area being known. All public sporting facilities in Hong Kong are heavily subsidised. Users of these facilities do not pay for the land premium: if they had to, the prices would be prohibitive. Private facilities fall into two types: residents' clubs, for which the land premium is essentially built into the cost of the apartments; and the 'elitist, expat-orientated' clubs that were the subject of the article. That these latter are also subsidised is true. That they are not easy to get into is true: commitment to whichever sport is needed. That, unlike public facilities, their running costs are not subsidised, is also true. That they form the backbone of sporting life in Hong Kong, by contributing large amounts of voluntary time organising events (leagues, competitions, Rugby Sevens, Cricket Sixes, etc), is also true. I am not representative of the membership, but neither is my case atypical: I could not afford the cheapest one of the 'Mid-Level flat' rents that these clubs pay for their land. Anyway, there's a much simpler way of looking at it. I can compete with everyone for the use of public facilities for free. I can compete with 55,000 members of the South China Athletic Association for their facilities for $100 per month. Or, I can compete with the few thousand members of my club for its facilities by paying $1,000 a month.
