That looks like a windy place. I did a yacht charter on Gippsland lakes many years ago and it blew every day. The only days I didn't sail was when it was too windy.
Any advice on what gear to bring?
Bring everything Cluffy. Inverloch has a frontage weather system and in the past we have had everything from 5 kts to 30kts.
Guy prefers little wind as he can teach you more!
