My, soon-to-be-mine, R-27 (2012) is going to need insurance. (180 Hp Yanmar)
The insurance agent is asking for a top speed. The seller has claimed ~18 knots.
Since the insurance premium is a function of the top speed, I probably ought to get it right.
Question: Is there a published/official top speed for my boat.

Thanks
Rich
 
Rich,

With my previous 2012 R27, my measured top speed when brand new was 22 Knots, with 1/4 tank fuel, 2 people, no water, no waste, and none of our stuff. But later after filling it with fuel, water, waste, all our stuff, and 2-3 people, the top speed was typically about 18-19 Knots. But if there was a lot of build up of crud on the hull, the top speed was never more than 18 Knots. So, the answer to the insurance agent's question is not straight forward.

However, there are published numbers for the newer R27s with the Volvo engine as shown in a previous posting by Baz:

In that posting, see the link provided by Baz to a Powerpoint presentation with all the official numbers:

We have a 2012 R27 that we've owned since new. I looked in my log and see several wide open throttle logs where I was testing top speed. I've recorded between 21 1/2 and 22 MPH. 22 MPG = 19.1 knot, so close to what the prior owner told you. The numbers will also make a bit of difference if you're in tidal water, especially going against and I've heard salt water makes a slight increase in speed then fresh water. These numbers are with our boat reasonably loaded for normal cruising. It will be interesting to read what others have experienced.

Our R27 recently showed 3950 rpm @WOT speed of 15.2 knots, 1.6 nmpg, engine fully warmed up, calm day, no current, and trimmed for some bow down, 1 person, no cruising supplies or gear, no water, no waste, 3/4 tank fuel, all safety gear.

Seems like the last time we had it WOT on a cruise we were lucky to get 14.4 knots with both of us and clothes, gear and supplies.

Most times though I usually go about 3400 rpm, 12.5 knots, 1.9 nmpg. (fully loaded/2 persons). might get 13.5 - 14.0 knots empty w/1 person.

Is it safe to assume that all of us have the same prop?
 
Crewdog,

Your speed does seem slow. We usually can achieve around 16 knots at 3600 RPM fully loaded for a week with two persons and a full tank of fuel with no current. At WOT we usually can do about 19 knots at around 4000 RPM under the same conditions. We have the stock propeller from Ranger for the R27.

Is your bottom clean? Are you sure there was no current? Often the predicted current for the area doesn't match actual. We once achieved over 22knots with 4 persons fully loaded with gear. Clearly there was significant help from the current. At other times I can't get much over 16 knots. Again clearly bucking the current the other way but not indicated on the tables.

We get 20 mph at 4000 rpm got to play with the trim a little get that moderately loaded for cruising. Sort of squeezing it to get that. If you tell the insurance man 20 mph I think that is fair enough. I pretty sure the insurance man is not going to demand a sea trail to double check your speed. I would think speed would increase your premium if you told them your boat could do 40 or 50 mph. 😱
 
That is not a question I've been asked by an insurance agent before. They just looked the boat up and gave me a quote.

But I doubt it matters much 14-20 mph. Not a speed demon.

I'll be needing to purchase insurance for my new boat I'm picking up the end of the month, so I'll let the group know if I get the same question. May be a new thing the industry is using to justify jacking up rates.
 
I was asked that in 2012 when first getting insurance. I really think they just want to make sure it is not a go fast boat. As stated I'm sure 14 - 20 will put you in the same class. You could ask when you are talking to them ? I really don't think a few MPH either way will matter.
 
I have owned two Rangers R25sc and the R27
and yes top speed in the R27 is 18 knots.
You will love it.
If you ever have questions talk to Andrew, he will hate me
for saying it but you will always get the correct info from him.
 
I know the OP was in regard to insurance, but while we are talking top speed, how much time do you actually travel at WOT?

We try to take our R27 up to WOT for five or ten minutes each time we take the boat out. I was told to do that by the factory captain to clean things out and keep it humming at top performance. I was also told the engine likes to be run pretty hard long term. 3600 RPM all day not a problem! The boat seems to like about 3400 RPM though so that is our more typical high cruise. Of course we still like to spend as much time as we can at 1600 RPM if we have the time as that is more leisurely (and quieter!).
 
Our 2011 R27 (Bobolink) did 18 knots with 65 gallons of fuel (all other liquids full) at 3600 RPM, with the Yanmar 180 Hp (4b2y?). We had just cleaned our hull at CSV, but the boat easily had some speed left to give. 18 knots seems to be a low estimate, like others have said prior to me.

This is one question where you err towards a lower speed. While a max speed is for showing off none of us go that fast. Bye my Allstate insurance did not ask such questions.
 
When we took delivery of our R27 Blu Tug with a full tank of fuel and 2 people on board at WOT was 24.7 knots after time the speed dropped but after a hull clean we achieve 22.5 as there was more weight added to the boat.

My 2011 R-27 will do 20 knots under ideal conditions, more often with a load 18 knots at 4,000 rpms.
 
Hi Rich,
No offical speed is really posted since as other posts note it varies depending on weight (what you have for add-ons, how much fuel, ect..ect..). however the range of 18-22 or so knots is reasonable. If 18 knots gets you the better insurance rate I would go with that one 🙂
 
My top speed is 16knts. I had it up to 18 knts one time. With a nice day, no wind, no current, full tanks, gear on board, I would say 16 knts. Although 12 knts seems to be the sweat spot.
 
Looks like a dead issue, folks. My insurance agent tacked on about $50 extra premium for going over 20 mph (which is what happens at 18 knots). I can handle it. Not a problem in the grand scheme of things.

Thanks all,
