A few places to launch from. Poole/ baiter slipway, plenty of bays along the Purbecks.
Christchurch/ Mayors Mead slip, easy to park with a nice cruise off to The Ledge.
If you become a full member keep a eye out on the boat buddies, trip planning bit on this ere forums
100% doing the right thing, get out with the locals, im still finding my way after 20 odd years !
Huge learning curve, tides and being safety if the first priority, fishing comes later
You will find very little info on specific marks in a open public forum , plenty of info on general areas, every day is different from the last.
My best tip is look @ tides4fishing and gain a basic knowledge of when and why fish feed on turn of tides etc
