Well, there you are, folks. We hit 35 knots in both directions on flat water at high tide in the Carrick Roads. Since then we have put about 39 hours on the engine and it does seem that the boat - even with 600 litres of fuel on board continues to run at a speed that satisfies me.
It's been an expensive operation to retro fit a new lump but, with the deal to sell the 4-cylinder Yamaha to Stuart WAVEHUMPER Hopkins, it's been worth it. I now have a RIB that, to me, flies instead of lumbering, and if we can get 1.5 litres to a mile, we have a range of 400 miles.
At the moment I have no idea how much fuel we are using, nor the optimum revs for a balance between speed and economy. That's the next job. The Floscan fuel guage is on the shopping list.
Cheers for now...
