Log of SV Free Spirit and ships company

The chronicles of the schooner Free Spirit and her crew, embarking on an open ended journey upon the great rolling heap. Free Spirit is currently pursuing humanitarian and commercial goals in the Dominican Republic, on the island of Hispaniola. Working under the Ocean Reach USA and Paradigm Research banners, she is serving as logistics headquarters, workshop, and development laboratory for many ongoing projects. This is the log of her journey.....

East!

We stopped at the Smyth Ranch Near Junction City, At the Ranch of Ernest (1918-2006) and Elemay Smyth. They have around 1300 Acres, With cattle, horses, and Buffalo grazing, as well as farmland leased out to farmers in the area.

Ernie's son Donald still works the land, and the boys went out on a "hay ride" and fed the cattle with Don and Dad.





Here is our new travelling rig, complete with dinghy on top.

We stayed the night here on the ranch, and got lots of visiting done with Elemay , her son Don and daughters Charlotte, Sharon, Marjorie, Sandra, and Lori. (exept one wasn't there, and now I can't remember which one.... I also can't remember what I had for breakfast this morning, so there should be no surprise here)




Elemay and Dad With Valin, Drake, And Blayde.

Elemay was born in 1924, but still has the vim and vigor of youth in her eyes, as anyone who has survived a Smyth must have to make it through, I'm sure!








My lovely wife Laura, back behind the bar at the Smyth Ranch, salvaged from an Eastern Oregon ghost town. Ernie was quite a character, you can easily see by the things he had kept around his home!






Back on the road, headed towards the high country east. Beautiful country, but hard to imagine how the Smyths of old crossed this with a wagon. Must have been pretty tenacious folk - it still shows, to be sure.

Introducing Propcalc 4.0

Use Propcalc to easily match your hull with your engine, transmission, and propeller
Put the known data in the top fields, then hit the Update button to get the answers.
Results, of course, should be verified by a Naval Architect or qualified surveyor.
Data is provided for three bladed propellers of average type
For two or four bladed props, use the modifiers shown below.

Fill out the fields as follows:

Vessel LWL (ft) = Waterline length
Vessel Disp (lbs) = Vessel displacement
(max) HP = Rated Engine Max HP
Engine RPM max = Engine RPM at Max HP
Engine RPM cruise = Desired or estimated cruise rpm
(Cruise or Max) Kts = Speed to work the calculations for
Slip = Propeller efficience. 45% is average for a displacement cruiser.
Gear ratio = 1: Gear ratio of transmission
SL Ratio Adj. = This value will be added (or subtracted, if a negative value) to the calculated S/L ratio.

Key information:

If the "hp required" is greater than the "cruse HP", you have your cruise RPM set too low for your engine parameters.
If the "hp required" is significantly less than the "cruse HP", you have your cruise RPM set too high for your engine parameters.
If the "hp required" is greater than the "Max HP", then your target speed is too high for your engine/hull parameters.
The S/L ratio is calculated automaticaly based on your input. It can be adjusted if necessary, but normally it should be left alone.
If the calculated S/L ratio exceeds S/L MAX, then the results are likely to be non-predictive. Try a lower speed requirement.
SL Ratios of 1.1 - 1.4 are typical of displacement hulls. Semiplaning or planing hulls can go higher.

Typical propeller slip values:

Sailing auxiliary, barges, etc less than 9 Kts............45%
Heavy powerboats, workboats 9 - 15 Kts....................26%
Powerboats, Lightweight Cruisers 15 - 30 Kts..............24%
High speed planing boats 30 - 45 Kts......................20%
V bottom race boats 45 - 90 Kts...........................10%


Note:

it is possible to get irrational answers by irrational input , I.E specifying excessive speed for hull type and length
Any attempt to exceed hull speed (1.34 times the square root of the waterline length in feet) with a displacement hull are likely
to fail unless the hull is extremely fine (multihull) or otherwise exceptional. In such cases, an S/L adjustment would be in order.

2 and 4 bladed props:


For two bladed propellers, multiply the diameter by 1.05, and the pitch by 1.01
For four bladed propellers, multiply the diameter by .94, and the pitch by .98
