Frustration...

...anyone know where I put the key? As well as wooden boats we also have an interest in retro vintage boats. This one is a 1969 Spierling built in Holland and still with it's original Mercury 50 engine. She flies like a dream so as it was a sunny day and we had a gap between bookings we though we would take a spin. Went through the trickey procedure of getting her into the water off the trailer and ready to start her up when I realised I had the wrong keys. Here is Reliance back on the remorque ready to go home :( I've been searching everywhere and can I find the damned keys grrr!
