All good fellas.
They guy with his kite down had lost his board upwind and couldnt relaunch his kite.
I kited out and planned to retieve his board and deliver it down wind when he got his kite up.
Trying to manage two surfboards I dropped my kite and then accidently releaded my safety (cabrihna)

. I then lost my board up wind

(still had my mates board)
I reset my safety, relaunched and started to tack upwind to look for my board (wasnt going to give up easily on my beloved Nugget). It look a while but when i found it I used a short line and clip I keep tucked in my harness to attach to my board to my harness and headed in towing my board.
My mates kite was still down but he was getting close to shore so I kited past and told him I had his board, took his board to shore and kept an eye on him till he reached the beach.
A guy from Seaford Lifsaving club also came out, he must have also called the Police as they came to see us back at Carrum, confirming we were OK.
A few lessons learnt but all good in the end.
