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.....

Home Will Always Be There

To our dear friends that we hold close to our hearts that we did not make it to see...... We will be sure to see you on our next journey home!

Above, we had a great, although short visit with our old friends the Botulinski's. The kids had not seen each other for about 4 years, and it was a wonderful afternoon reunion. We wish you well on all your future travels and endeavors!

Blayde and sweet Evelyn having a special moment... We so enjoyed seeing all your socks and shoes! I do not envy your parents when you are a teenager :-)

Our little Karen, who I was able to see come into this world, is such a beautiful, smart little lady! Tell your mom and dad that we can't wait to meet out on the water!

Here we have a collection of busy boys at Richard's 6th birthday party. I cannot believe that it was 6 years ago that you came into the world. What a smart young man you have become!

My amazing twin nieces.... Can you tell them apart??

What could be better for a going away party at Goldstream Park than; Friends, fire, fun and hot dogs??

There was still enough snow left for a little snowball fighting.

Drake and Max enjoy a little popsicle action, while Ramey and Annabelle slide on past.

The yard of my refuge..... My dear friends allowed me to take a break and stay at their new house with them for 2 weeks, without children or obligations. It was a well needed resting place, and I will be thankful for years to come.

My last night in Fairbanks, I vowed to see the sun set and the sun rise in the same waking time period.
This is the sun setting over the porch on Gilmore Trail at about 10:00 p.m.

Here is the sun rising off of the same porch, but about 45 degrees to the East of sunset at 3:45 a.m.

The start of a new day, brings new visions of the day ahead, and more adventures to come.

I'm sorry that we didn't get to spend some time together, but I'm glad you had a good trip. Nice to see you posting some photos again!

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%


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
