Fist of all Welcome to Ribnet!
Levington has a good slip which you can launch and retrieve at almost all states of tide for access to the river orwell / stour.
It would be worth downloading the Navonics app if you don’t already have it! On a calm day we often go to frinton and anchor up on the beach it’s not to far from levington in terms of Nm.
For Brightlingsea area I have always launched at Morgan and Sons Ltd. they have great facilities and will also launch you with their tractor for a small fee!
In terms of safety aspects, make sure you have a VHF radio hand held will be ok and I recommend doing the VHF operation course to qualify you to use one if you haven’t already ?
Make sure you carry an anchor it can become extremely handy if you break down!
Having an in-line fuel filter and spare tank would also be sensible. The number one cause of breakdowns for outboards is dirty fuel. If you have a fuel filter & water separator you can almost eliminate this
I’m sure you’ll love it, Enjoy [emoji106]
