Thanks Sailingdog! I really appreciate it.
The batteries were due for changing anyway...so no great loss.
I don't have solar powered vents. I'll put some in.
Working the seacocks, head and faucet area good idea. They were working perfectly. To winterise I pumped through "plumbing antifreeze" throughout. (head and all faucets, as well as through the bilge pump and engine cooling system).
I applied lemon oil on most of the interior woodwork. The interior should smell clean and fresh!
She was in such good shape when I winterised!
Now based in Barbados.... and wait for it.....the boat is too!
