Could you let me know where you bought the project of your boat, I found the project of OB20 to buy but the design of your console is different and I really liked your model.
Good HP choice , I'm pretty sure it hit 40 knots + , and will be very economical at cruising speeds . ( the bigger the better ? )
We are having great time with our boat
good luck !
Thanks a lot Graham, really appreciate your comments.
This was all possible thanks to your hull designs and your technical help and support .
Would also like to take the opportunity to thank all members in this forum that showed their interest in this build !
Thanks every one and happy building ??
Working on a shading top attached to the radar arc, that can be easily folded down. It is fabricated with 40mm x 2.5mm wall thickness aluminium tubes and should weight less than 8kg when covered with upholstery.
Some more updates !
Decided to uninstall and remove completely the Bennett auto trim tabs setup and moved to zipwake interceptors.
These new fully automatic interceptors are very fast acting and I am 100% satisfied with their performance , although the main reason for switching was that the trim plate itself made it very difficult to maneuver the boat in reverse gear . Some times but not often they also interfere with the fishing line , risking to loose the catch !
Totally agree with you, and yes I meant 36 nautical miles .
I don't know what measurements use in the rest of the word but in Europe we us Knots for speed on water and meters for depth and that's the way most of us sett their instruments
Thanks Riggs.
Today another test run !. Think we matched the perfect prop for this boat . 3 x 16 x 21.5"
Cruising speed of 23Kn (26miles) at 3650 rpm and burns 17 liters of fuel per hour
Top speed (WOT) 45Kn (51.8 miles) at 6150 rpm
A total trip of 36Kn (41miles) in 2 hours burned 28 liters of fuel .
Think that these motors and this boat are super efficient !
Now the boat rides very stable at all speeds. Very happy and satisfied with all the results and thanks again to Graham !
As promised here are some photos.
We have tested the 4 blade prop 20" pitch. It performed very similar to the 3 blade 20" but also generated lots of lift . WOT was 6050 rpm and 38 knots . Still think that best prop will be 3 blade 21.5" pitch. That will be her 4th and last test
Best cruising speed was at 3600 rpm 22 knots and 0.8 liters per knot mile .
