Cruising speeds

Just thought a poll would be interesting based on the responses in the thread on this subject.

You may select multiple answers if you cruise regularly at two different speeds or for multiple boats.

Yes, redundant, but meant simply to supplement the existing thread by capturing the numbers. Not meant to start an additional discussion as the existing thread is great.

Planing speed cruising is around 22.5kts at 1750 rpm's (that's 80% throttle)

bump

just under 9 kn, 1750 rpm, 22 lph total, 60,000 lbs half load

I would prefer 10 kn or more but need longer & lighter boat to get it at the kind of fuel consumption I like

That's weird. When I looked at the poll percentages just now, the total was over 120%.

Poll heading notes that you can select more than one speed. I guess some with planing hulls have done so.

Yes, in the other thread quite a few people were giving two cruising speeds, so the poll was set up to allow that.

Thanks, but the credit goes to OC Diver for bringing the subject up and I just liked his thread which led to a desire to do a poll.

I'm surprised that 14 to 17 knots only has one. That's often a sweet spot for mid size full planning hulls... such as ours.
--- shows there are few TFers with boats such as ours yet to chime in --- must be some on board TF???

16 to 17 knots is my preferred nmph (most economical [around 1 nmpg] and good handling speed) while stepped-up on plane.


I also checked in on the first speed of below 7 knots. At 7.58 calced hull speed from 6 to 6.5 knots for our 34' loa Tolly is best (easiest going, more economical [around 2 nmpg], little wake) with both screws turning.


If we are in a real easy-daze mood I sometimes shut one engine down and drop to 4.5 to 5 knots for a whopping near 3 nmpg... but we sure take tide and current conditions into effect while cruising that slow.


If I did that speed in Hells Gate NY heading toward the Hudson... in most season instances I'd be going backwards at a knot or two toward the old "Acid Waters" area off shore. - That's a whole other story from mid 20th Century!

Yes, or two boats. In our case we have a 36' boat that cruises at about 8 knots and a 45' boat that cruises at about 35 knots.
