It''s not a loggable dive.... 
A Saturday in March... the weather for the last month has precluded diving in the sea, I couldn''t face another trip to Somerset, and so decided to do something dive related and hopefully interesting.
 
The Nautical Archaeological Society (NAS) run a series of courses form the Introductory course up to Diploma level. Its aims are to raise public awareness of archaeology underwater and on the foreshore.

That''ll do for me! It will help me to indentify the lump of crud on the wreck, before I er... salvage it for the benefit of everyone. It will also help me find the wrecks with all the sunken treasure, and give me some tips on recovery and disposable on ebay of said items!

Saturday, turns out to be the most divable day of the winter so far! So what am I doing standing outside DDRC in Plymouth, with Julie and Nick and I ain''t even needing treatment?

The day starts off very well. "Help yourselves to Tea and Coffee!". The paperwork and disclaimer are filled in, and the lectures start.

The Instructors for the day:
Sarah Ward. Development officer for the NAS (and an Aussie)
 
Jon Parlour. Instructor for the NAS, and with a wealth of local knowledge. He is Training manager at DDRC, and a BS-AC AI.

Introduction To Archaeology and the NAS
 
Sarah opened the day, checking we were all there for the course and not awaiting treatment in the pot! an overview of what we were going to, what archaeology is and what the NAS does.

This is more a case of draughtsmanship and drawing straight lines

But we drew our artifacts from the wreck of the Napoli
