Update and the rig for those interested.
Boat does 39 knots seven up with 350 litres of juice.
20 hrs on engines so far after 2 trips.
fuel consumption on second trip of 137nm was 280 litres. average speed 28 knots, ran from 39 and 00 to Gordons Bay no slower than 30 knots as we were in a rush .. 2 l per nm.
Expect at 4200 rpm, 24 knots fuel consumption will go to 1.8 /nm which is really really fuel efficient , exactly what we hoped for in times where petrol is so expensive! Need at least ten trips to get more accurate figure
Not one problem with boat build from kamassi so far. will keep updated especially after she gets punished this season coming up.
