G'day Twosheets,
Jode's speaking from experience, not much needed to add!
On a good fishing day it can be a pane of glass, and you'll have SUP's toodling around Green Island, those days you could sail a bathtub around the bay.
On a good sailing day it can get a bit tough for short waterline lengths, where the shallow water and opposing tides produces a short steep swell. the more open parts of the bay the worse it gets. The tides accelerate around the West/East of the islands causing a bit more standing up in certain spots.
On bad days, the transom hung outboard on my old TS was near useless, had to get rescued by VMR one day after losing a main halyard and not being able to drive off the shore in 35 knots due to heel and nasty wave action.
Would be fun to do on a light air day, and no fun at all in medium to heavy airs.
As an alternate, have you thought about lake sailing if you're keen on dinghy and beach cats? ? Lake Samsonvale have a great spot for sailing and a great little club, I sailed there for years as a kid, loved it.
