l have been told by other divers and our skipper this year that there are good wrecks outside Scapa Flow but they are weather and tide dependant and that you have to go deeper to get the more intact wrecks.

Two things John, hadly anyone goes to Scapa the diving industry up there is struggling to survive, it costs less to go on a livaboard to Egypt.
And I doubt that anyone can describe a unique wreck site like Scapa as nonsence or words to that effect, where else can you dive such a concentration of relatively intact, mostly sport diving depths, wrecks in a sheltered location in the northern hemisphere?  

Out of twenty four planned days diving in Scapa we've lost one day due to bad weather, which is another good reason to dive "that German high sea fleet nonsense that everyone goes to", or words to that effect.
