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.....

More Refit (We Will Never Get Bored!)

The start of the new paint system on the deck area. Because Tamer was in Alaska, and I was working continuously, I do not have any pictures of the work in progress :-) So you will just have to have all the finished ones!

Tamer sanded down and applied linseed oil to the helm seat and steering wheel right before the Schooner Race (post coming soon).

The paint still needs to be finished on the aft deck, but this was to highlight the new paint job on the deck box and the freezer.

The sand is more of a highlight color and then the non-skid is a new shade of almond.

I am super proud of how everything turned out. I have been visualizing a "finished deck" for years!


When we get down into warmer climate, I will be trimming out the windows and hatches with a black stripe. I think it will be the 'Icing'...

There were a lot of a reason the deck that required a few coats of fairing compound to fill the pitting. The above picture is the 'before'.


Valin ~ Sanding away on the deck.

Raoul and Valin re-coating the very forward area of the ship.

Raoul's Urbanna Project was to grind and sand the bilges in the aft cabin. They were never finished while we were at Glade's. I did not take near enough pictures of his accomplishments during this project. This is the area furthest forward in the aft cabin under the existing floor. The area under our bed was probably 10 times more work than this area.

More before

Here is Blayde laying inside the area and vacuuming (one of many times).

This is Raoul the contortionist applying the final coat of paint. I did not get any finished pictures before the area was re-stowed full of stuff. Rest assured that now there is no rust, and only a shiny new finished coat of Amerlock.

A big thank you goes out to Raoul for taking on this difficult project!

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
