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.....

Tavernier, FL To Titusville, FL 5/29 - 6/1

Sunset in Tavernier off the Port side.



Carpenter Dave, just hanging out enjoying the evenings sights and sounds.



YAHHHHH!!!!!!!!!!! P'tit Louis finally next to us, under sail on our way to Titusville! Leaving here was the first time that our 2 ships traveled together to a new port. We did not have Dave for this part of the journey because he was crewing for Nathalie and Olivier, and due to the fact that we were short handed, Gina joined us for this trip.



The night lights of South beach in Miami.....
Ok, I know, use your imagination for a moment :-)



Saaaiiillling, takes me awaaaaaaay.......



Raoul and Gina 'riding the bow sprit'.



P'tit Louis leading a pack of unknown boats up the Intracoastal Waterway. Just thought it was a neat shot...



Need I say more??????????



~P'tit louis again, the boys and Dave were aboard during this day sail up the waterway. They had loads of chocolate, and we got boared...... Bored?? No! Board! Check this out.....



Tamer has always wanted to see what would happen if you were to attempt water skiing with a sheet of plywood and a sailboat going a whopping 7 knots..... You know what they say about a genius mind don't cha? Yah, I understand, neither do I :-)



I could not believe that with just a little skeg screwed into the bottom, you could actually get some air! As soon as I can figure out a way to shrink all our short videos, you will have to look in the archives for this series. They were awesome! It was so wonderful to see Tamer not working and enjoying the "Free & Easy" lifestyle!



I was not willing to be scared to death in the alligator infested water, but of course, Gina was!! She had a wonderful time, and along with Tamer saved me some rationing on fresh water for their daily showers ...... Oh wait, I guess that will make more sense when I get the video up :-)



We rafted up to P'tit Louis, and had only about enough time to grab the camera, scan the horizon, and the shuttle was off! What an amazing sight!! It was surprising how fast it was done and over, but remarkable to be there for such a kewl event. It was great to get to see it up close, and NOT have to spend 2 hours in bumper to bumper traffic getting off of the island and back to the mainland from the launch area.



~Up The Mast~



Enjoying a "shuttle cocktail". Our wonderful and dear friends, WE MISS YOU!!!!!!!!!! Cannot wait until Fall!!



Drake, as always, doing tricks at the marina office, so that I can take his picture... He is definitely the daredevil of the family!
Our newly married (at the Frisbetarian Wedding) friends Leonard and Julie, are finishing up some small details on their steel boat in Titusville. It was really wonderful to have free use of their car, and to have showers included in our $5.00/day fee for the dinghy dock. Nathalie and I were able to get some major provisioning done with the car, and that was great!
Thanks you guys, and we will be sailing out of Titusville together in November :-)



A beautiful bird at the top of my mast. I awoke to a group of 3 of these playing around a small group of boats in the anchorage in Titusville. They would take turns dive bombing each other for their spot at the top of the mast. It was super fun to sit quietly on the deck and watch the way that the played and communicated. At some point in that 10 minutes or so, the boys woke up, and got to watch some of it with me.



Taking off for the next fun mast!

Those pics of Tamer and Gina surfing were awesome. You know that seeing the Space Shuttle go up in person is pretty special there is only like a dozen more scheduled to be launched ever.

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
