I finaly tracked down my Coastguard, James Woodgate....what an interesting fella he's turned out to be.
He joined the Royal Navy between 1840 and 1850 after a bit of research i've found out his last vessel was the HMS Queen. After that he joined the Coast Guard service and served in Kent, Dorset and Devon. He was promoted to Commisioned Boatman on the 17th June 1865 and then to Coxswain in 1870
http://dover-lifeboat.dovercliffs.co.uk/coxwains/coxswains.htm#During his time as Coxswain he won 2 Silver Medals and 2 Bronze ones for bravery at sea. I have found details of one of his Bronze Medals which he won for bravery 20/9/1867 at East Cliff, Dover.
I have to wait now till after christmas to get the details of the other 3.
Here is a pic of the HMS Queen in Portsmouth in 1842 - strange to think that my James might have been on Board then!
