First time on our own!

Went into Plymouth sound to practise some tacking (1320 - 1420). Really cold day, no other boats except a warship. We were doing well until half way through a tack we stopped - dead! A few minutes later (after trying with the boat hook & losing it) I was changed from thermals into shorts taking my first dip to free a lobster pot that we snagged up on. Must remember to look where we're going next time. Went straight back home.
