Hello everybody! (new member alert

)
I will be SIB-ing in Salcombe next week and this will be the first launch in salt water, normally we stick to the thames but have decided to venture a bit farther out!
We've been to Salcombe a few times so know the estuary a bit... but have been in hire boats previously, restricted as to where you can go. This time we'll have a bit more freedom.
We'll be on a Quicksilver 340 airdeck with a 15hp 2 stroke Mariner - looking forward to having a pootle around too
any recommendations... places to look out for or avoid?
What lurks beyond the Wolf rock... will our set-up cope!?
any tips for a marine first-timer?
cheers all
