I guess unless its a particularly light and slippery boat around 36knots max,
more likely in any thing less than mirror flat conditions to be 28-32 knots if set up correctly.
EG 5.4 searider with 90 yam 1 person ~38knots in flat calm.
same boat 3 up slight chop nearer 30 knots.

I got a shakey 5.2m with a 70hp tohatsu on the back. I have recorded 36 knots (GPS) with 3 up. I'm too scared to try it on my own cos she's lively trimmed out and I can't steer and hold/look at the GPS at the same time

I also think I can up the pitch on my prop by an each (I think its a 15" on there at the moment).
