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.....

The Deltaville Experience 7-16/7-21

EEEW!! More jellyfish in the sea strainer! They clog up the filter, and the generator or engine using the seawater for cooling gets too hot.

Jellyfish frappe. Yummy! (but don't touch, it still can sting you!)

Jellyfish, frolicking happily, in search of a sea strainer to clog.... There were a lot of them in Deltaville - they call them sea nettles, I call them annoying!

A big one, on its way to someones intake.... Too bad you can't eat them, we could have stocked up for the year, no doubt.

Bottom job - once again, time to clean the barnacles off the dingy. This job usually falls to Blayde's work detail.

While we were anchored out in Fishing bay, just off Deltaville, we decided to do some of the more heavy work that might not be welcomed at the dock we were hoping to find there. A few cracks needed welding on the capstrip, and some unaddressed corrosion issues were found on the deck hardware as well.

ZAP! This is what I like about having a steel boat. Insta-fix, as good as new! (well, not quite that easy, but compared to wood or fiberglass, it is a cinch!)

This cleat was so badly corroded that it had to be cut off the deck to be repaired. I'm not sure how we missed this in the yard, but I guess we were bound to miss a few details on a project that size.

Here you can see the hole in the base of the cleat. We cut it off, and using the welder, applied layers of new metal to the old part to build it back up to it's original shape and strength.

A Half hour and 20 or so welding rods later, and wallah! like new. Now to weld it back on the deck...

...Which was easier said than done, because some of the welding had to be done from the dinghy, which was being buffeted by the chop and the occasional wake of inconsiderate boaters.

But in the end, the job yielded to the indomitable will of the ignorant, (they who either do not know or refuse to believe that a task cannot be completed) and the cleat was reattached.

... then Laura, painting in her nightshirt, adds her finishing touches - and one can scarcely detect that the job was ever done - or needed to be. Ah, the joy of steel!!!

Laura the lovely, sitting outside the 7-11 convenience store.... Luckily for us, they were having their grand reopening, complete with coupons for free drinks, slushies, hot dogs, doughnuts, and coffee. We scooped up far more than our share, and these coupons quickly became a hot trading commodity onboard. In the end, I think 7-11 supported our appetite for junk food for the better part of a week - gratis - and we still have many cupons left, which we shamlessly continue to use at other 7-11 stores, much to the consternation of the employees who know nothing of the promotion.

Do I feel guilty? Nope. 7-Eleven, Inc. is 65 percent owned by IYG Holding Company, which is in turn jointly owned by Ito-Yokado Co., Ltd. and Seven Eleven Japan. The latter is itself a 50.3 percent owned subsidiary of Ito-Yokado, which is a leading Japanese retailer. The result of all this you see, is that my mooching off the 7-11 dole is helping to balance the trade deficit, by keeping american dollars from flowing overseas. If only everyone was so civic minded!

Deltaville, like many other places we have been directed to, was wonderfully pleasant, but altogether inadequate for handling a boat our size unless we wanted to pay a premium price. It would be Ideal if we were under 40 feet, but at 65 overall, and 37GRT, we have the needs of a small ship when it comes to dockage.

Once again, we find that most sailors cannot apreciate how the needs of a boat our size might differ from those of smaller vessels, and I suppose I should have anticipated this.

If we had not needed to find a secure dock (I would be leaving the boat for a month), the anchoring was fine - but unfortunately, the marina that could accommodate us wanted to charge yacht prices for our workboat budget, and the other docks were either too dilapidated or too shoal to safely hold us during any kind of weather.

Fortunately, we found our next port, Urbanna, right away. By this time, I had begun to realize that the places where we were best served, and most welcomed, were old deepwater harbors. These harbors tended to have a stronger maritime tradition, better shelter, less shoaling, and a more embracing culture than their fishing village counterparts. The local culture seemed to intrinsically understand the needs of the sailor, and not just see every boat as a cash crop....it is like the difference between welcome to our town, and welcome home. The cultural divide is easily as dramatic as island vs. mainland culture, and now we were about to get our best example of it yet, but that is another story....

Laura, you look fantastic. Being out on the sea is doing you good! :)

My name is Becky I am also from AK and have 4 children. I can't beleive that I have found someone living my dream. I would love to hear more about how you guys are putting together the money to pay for your adventure. And any other helpful hints that may not be on your blog. rrmckimmey@gmail.com

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
