MA spots are right on Adam

Marmong has the formula racing on a Saturday arv and it does work in a Soueaster as well
Coal Point and Shingle splitters (access by Morisset peninsula, follow signs to Balcolyn) are the best in a NE and have large grassed areas for rigging. Coal Pt also has the benefit of sailing behind the old airport (belmont) in smooth to super smooth FLAT water - great for gybing practice
On the southern end of the lake - Bardens bay / Sugar bay on the Morisset peninsula for a NEaster and Morisset Park / mental hospital site in a Swester - bit weedy at the launch
Shingle splitters will work in a westerly - but i have never done it
Another option is both the harbour entrance (Newie) and channel (Swansea) - havent sailed their recently but both are good for bump and jump
