Absolutely correct on all accounts, TDW. I keep my yacht here and regularly sail on the river and down to Fremantle and Rottnest Island. The Swan river downstream of Perth is quite a large expanse that is popular for yacht and dinghy racing and other water sports. Consistently throughout spring and summer we have a good seabreeze that is great for sailing. Those keen enough sail all year round
The only drawback is three low bridges at Fremantle. All but the smallest of sailing craft on the river have to lower their masts to get access to the ocean.
Over to you TDW.
