^ Generally Train = N and Shearwater = S
Shearwater is very tidal flow affected which can be great, the tide flows in/out the seaway of course, just to the south. Can run at 4 knots. Just use your noggin'
Best on outgoing tide and a SE.
The Train needs some East in it as there are a LOT of buildings to the south.
Can be great in a SE too but best in a NE seabreeze, summer's day etc.
You can probably see on GoogleMaps there are a lot of other places to sail in teh Broadwater

Oh yeah, Sunday is boat traffic day.
