Thanks GBC, its certainly doing my head in with the research available online. Was so much simpler before the internet. Walk into store with cash out with kayak...job done. Thanks for the offer of the rosco.
Store/load/carry/launch are all ok there are trolly's and kayak loaders for that. I understand what you are saying about a tandem but was trying to tic as many boxes as possible. Might just go back to the Viking Nemo and see how it goes, if it doesn't suit I can put it on ebay and get a single.
