RE: [bolger] Idaho: some numbers and photos

Hello John: I don't have a tachometer for RPM reading. The documentation on
internet of my motor, the standard propeller is diameter 9 1/4 x pitch 10,
but I will check it next time I go to the club. Thanks, regards, Máximo.

What are your rpms at WOT and half throttle?

You may not have quite the correct propeller pitch.

I'll second that. I tow my bantam, which weighed out trailer and all at 2740 lbs, with a Kia sedona van with the 6 cyl. I've towed it from MN to FL and back, and MN to TX and back, plus lots of shorter trips of under 250 miles.

Thank you Bob.

We have also some very expensive marinas near downtown, and they charge you
extra if you live on board.

Also keep in mind, it's difficult to compare, because our average salaries
are lowers than USA, Europe and many other countries.

Thank you all for your kind words. This group is a great inspiration to keep

grrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrr...

I remember now, on the Diablo (160 kgs, 1/5 of Idaho's weight) with the same
motor, I made a maximum speed of 18 knots. So 13.5 maximum speed on Idaho
seems OK.

My background is sailing on sailboats, so any speed from 4 knots is great!
:)

Also sailing protected from the wind and spray, with a panoramic view, 10
knots on interior water, with almost no wave nor noise... is excelent.

Argentina) we are a union non profit society, they charge for a minimum 20

Beautiful and apparently very true to the plans. I own a set of the CSD plans bought 2nd hand a few years ago. I admire the simple windshield treatment at the bow.

Except for the storage/trailering problems of a 30 footer, this seems an ideal picnic/day cruiser for several, with nice occasional camp cruising for 2 on rivers and many lakes.  And one could leave off the cabin, go to a planked deck finished bright and have a bargain gentleman's speed boat, again for protected waters

IMO, without knowing more about the prop and engine rpm it is difficult to know how many of the 20hp are being used.  The cabin is a major aerodynamic drag, so head/tail winds will have a big impact. 

I recall the prototype having a 25hp 2 stroke Mercury on it.  Those old Merc's were noted for their performance.

Maximo:

 

Congratulations on the launch.  Very nice detail on the interior.

 

I run Esther Mae (Tennessee) with a four stroke 25hp and being close to the plans (double 3/8” bottom with 3/8” hull and cabin top).  When first purchased the engine had been sitting for about two years.  The engine started on the day of the test drive without much hassle and produced boat speeds of 12 – 14 mph with economy of 10 mpg running wide open throttle.  Now at over 800 hours and in excess of 4,500 miles I regularly run at 16 mph but have not checked the economy lately.  I suspect that the biggest factor in the speed is ethanol in the gasoline.  I regularly run a gas preservative that is intended to eliminate buildup in the system.  It is possible that over time it is still removing gunk from the carburetor.  I talked with a service technician at the local Yamaha dealer and he said that with the pre 2001 models the jets in the carburetors are large enough to deal with the ethanol and that there is little that can be done to eliminate the effect of the stuff.  Apparently newer models are more sensitive to the ethanol and suffer reduced performance if left sitting for very long.

 

Respectfully

Nice work Maximo. Thanks for the photos.

It's been a long time since Bernie built the first Idaho. I do recall he did not have the correct size motor.

A stunning job! Thank you for the inspirational photos, Maximo.

.

Gerr's standard tables of power to weight ratios reflects a typical light, flat bottom boat planing at around 13.9 knots. Your boat is different though in that it's said not to have any noticeable hump.

Your own 90 pounds / horsepower is off the planing chart, but 80 yields a top speed of 22..5 kt. Off 10%, might still come closer to 20.

Looked at another way, with no planing involved, the displacement boat chart shows a little over 13.25 knots is just exactly what to expect for your boat.


The 1200 hundred pound, 20 hp,  60# / hp boat could hit 25.
More conservatively than advertised, the 12 hp boat could be as low as 11 knots; or up to 13.9 with Saturn on your side . Still faster than a  sailboat.

I wonder if this means that if you could only go a little faster you might go a lot more so.

Weight: 810 kgs (1785 lbs)
(complete w/motor, gas, equipment)

Max Speed: 13.5 knots
Half throttle: 10 knots
Honda BF20 20 HP, long shaft. Two people crew.

On common sense website the empty weight says 544 kgs (1200 lbs) and 14
knots on 12hp. Could it be, the difference in weight affect that much the
speed?

Very happy how it feels.
