I live in the HK Gold Coast Marina. A 65ft berth fee is HKD $6955 per month, I think a 55ft berth fee is approx HKD $ 5500. A debenture can be obtained for around 85K, but they are increasing and hard to come by now I believe. There is also a subscription fee of $1050 per month and $180 per month for each other family member, in addition there is an $80 electic admin fee plus your electric usage
