David, we simply take the normal precautions to prevent water ingress, and wash down well with fresh water after each sailing session. I have never had a problem sailing in salt water in the 5 years I have been doing so.
Our local council built a wash down table for us, and laid water on as well, so we can’t complain about them not helping us.
As a matter of interest I, and about 6 other club members, spent from 8 am until nearly 3 pm today running a barbeque at our sailing lake, in co-operation with the Ballina Shire Council. The council held a tree planting day at the lake, as part of a park beautification program, and invited high school groups, and any one else who was interested, to plant a tree, and a barbeque meal was provided free. They asked our club to run the barbeque, and said they will reimburse us for all costs, and give us a good donation as well.
We cooked over 150 sausages, over 500 trees were planted, and a good day was had by all.
Peter.
