Thanks for that. My extrapolations would be pretty close to that; I'm comparing Goblin to a 30-foot Broads yacht (Lydia, now at Martham Boats following the apparent sad demise of Southgate's) with a 10bhp Yanmar Diesel, which would do about 7kt under power (and slightly more under sail.) She's a bit bigger than Goblin but lighter and shallower draft.
The fiction isn't mine, but I've been chatting to the author and thought this would be a good place to get some details they need. The scenario is the S,A & Ds doing a spot of unoffical surveying in the Baltic in 1938, with Goblin and Sea Bear. It's at http://www.fanfiction.net/s/8487174/1/Baltic-Adventure
