  1. Just a wee note to say that the radar on the sweepers when I was in fact a Kelvin Hughes radar and the RN type number was 978. On the Wolverton we also had it upgraded to have ‘True Motion’.

    Cheers,

  2. Sorry, loss of the grey cells I guess. It was a type 975 radar and not 978.

    Cheers,

  3. Re Ships Boats. The Tons were initially supplied with a 16ft SMB (Slow Motor Boat), which was clinker built and powered by a single cylinder, 10 HP Enfield engine, speed 6kts. They were open boats but i seem to remember that a small collapsible canvass canopy was supplied to be rigged f’w’d. However, in Appleton 1968/9, we had a Dell Quay Dory powered by a Johnson 40.

    • There’s posh a Dell Quay Dory. Thanks for contacting us Ken. I only recall the SMB, think we had a canopy but seeing as we were all roughy tuffies on my Tons I dont recall us ever using it.

      Best wishes
