Sailing, Cape Town, Yacht Racing, I did a bit of bridge work - checking the racing keelboats at the start and finish - and it was watching some of them that the idea for Vital Spark came to me. All production boats if the same type are the same. What distinguishes them is the name and the number on the sail, both easily copied. The idea developed beyond that but I might come back to it one day. I miss the yachts nodding to each other at the jetty.http://www.amazon.co.uk/Vital-Spark-No-Witnesses-What-ebook/dp/B00UNNKUUO
