Re: 19Ft Nemesis Cat Build
Well done , looking great!!
Re: 19Ft Nemesis Cat Build
She sits very nicely, congrats on what looks to be a solid boat. Motors obviously not run in but any idea sensitivity to trim, WOT numbers, cruise speed/revs ... ?
If you think going on an adventure is dangerous, try routine .... its leathal !

Hi Mombak,
She performs well with her current 17p props but for the current weight I feel like she is slightly under-propped and could easily push 19's.
Top speed we got with the 17's is 36 knots, two people and about 75L of fuel onboard but I feel with 19's we should get about 40kts as she is hitting 36kts before she is at full rpm of 6150. At 3800rpm she is doing about 23kts.

For fuel efficiency I think the 17's are a better option, especially when running in lumpy seas or when you have a full crew. Will also require less throttle management. Very seldom are you going to run at more than 28knots. Higher pitched props will only give you better fuel numbers if you are travelling fast with a light load.A1ex wrote: ↑Tue Jun 21, 2022 1:05 pm Hi Mombak,
