A Good Book for Sailors

| 0 komentar |
I promised you no more book reviews in 2014; but the new year is in full swing.  This book was given to me at least several months before we left NY in early October by Judy, a dear friend of mine and Lenes, who sailed with us for a few days in the Turks and Caicos in early 2012. Her book group read it and liked it even though they are not sailors; sailors will appreciate it more.

It is about three generations of the Scottish Stevenson family. Robert Louis Stevenson would have been the fourth had he not forsaken engineering for literature to the great disappointment of his family and with a personal sense of shame. The three generations built most of the lighthouses of Scotland and supervised their operation.


Two threads are woven through the book. One is the biographical -- the marriages, births, deaths and personalities of the men, mostly the men, and their wives-- a personal story. The other and vastly larger part tells the story of how they built the lighthouses, against all sorts of obstacles.

Both parts were interesting, though the later was far more interesting to me. Much of the personal part relates to the efforts of fathers to induce their children to follow their footsteps into the family engineering business. Robert Louiss father was himself drawn to literature but was forced to abandon it to study engineering, which he then tried to force his son into.  The fathers drove themselves very hard and demanded as much from subordinates and their children. Except for the first generation, the men suffered from weak health, which was exacerbated by long days of strenuous physical activity in cold wet places.

There is a skeleton family tree which is incomplete, in the sense that the text names various members of the family who are described on the tree merely as part of, e.g.,  "two daughters."

More irritating to me, the sketch map of Scotland at the front shows the names of some of the cities, islands, firths and lighthouses, but is terribly incomplete. The lack of a proper map in a book that is about locations was the major obstacle to my enjoyment of the book. The author refers to so many places, possibly presuming that only persons who are quite familiar with Scottish geography would read her book. The Stevenson family also designed much of the "new city" of their home, Edinburgh. I tried to use Google Earth to figure out which roads were joined with others. Subsequent changes to the landscape are what I blame for my inability to complete that task. There are sixteen plates showing the most famous lights and portraits of the Stevensons, but none of Edinburgh. Bathurst is very able to draw pictures with words, but maps would be so much better.

Bathurst also mentions big events in Scottish history with which I had not even the vaguest idea. Jacobites were Scottish revolutionaries, and "The Clearances" was the process by which the landed gentry forced the "highland" Celtic peasants off the land to make more money from sheep. This contributed to the Scottish Potato Famine. Some of the "crofters" went to the "lowlands", areas in the southern and eastern parts of Scotland, others to America. But all this I learned from Google after Bathurst merely mentioned the terms.

Another minor defect in the book is the absence of any footnotes to support the statements made. I would like to know if a given statement about a person is the authors conclusion from one or more documented episodes, from her reading of his letters or journals, or based on a secondary source: either a biographer or a newspaper. I am used to David McCulloch and Dorris Kearnes Goodwin, who give you the source of every statement in their books. It is not that I want to read all of those footnotes, but one feels more comfortable knowing that they are there. Ms. Bathurst does include a bibliography and she seems quite knowledgeable and won my trust after a while.

Most of the chapter titles are the names of the most famous of the lighthouses, each more challenging to build than the last, by which successive generations of  Stevensons made their reputations. Bathurst makes the point that each lighthouse needs to be designed to fit the requirements of its site, not aesthetically (though that was true too) but from the viewpoint of the engineering involved, especially the base on which it was to be built. Earlier lighthouses had been knocked down by the waves.

There were also political battles to be won, by the Scottish Lighthouse Board against British control, and by the builders against the wreckers who made their living from salvage and accurately perceived that the lighthouses would diminish their livelihood. Religious people argued that God had put the shoals where he did, and if he had wanted to, he would have put lighthouses there too. How can one argue with such a person.

Bell Rock, the Stevensons first, was built on a rock that was underwater at high tide. So work could only be done there, until the tower was partly built:  at high tide, in daylight, in the summer and in good weather. Not many hours of work per year.

The process of building the lights seemed to me like a scaling of Everest, where one has to establish a series of base camps leading to the final assault. In the case of lighthouses, these were to locate a quarry, create a remote land base where the materials could be assembled, acquire a ship to convey them to the rock, and then create: a landing place, a smaller temporary structure in which the workmen could live, the ring cut in the rock for a foundation, the foundation, the tower and finally the light at its top, before hiring and training the keepers.  And in some locations  during big storms, the waves threw tons of salt water over the top of and  into uncompleted lights and tore away blocks of granite weighing several tons.

The story also tells of the advances in lighting technology during the years, from a coal fire on a hilltop to candles with parabolic mirror reflectors behind them, to early glass lens concentrators, to Fresnel lenses.  And fuels advanced from whale oil to paraffin and even, after the Stevensons, electric bulbs, and the automation of the lights with consequent elimination of the keepers.

Bathurst includes other advances in safety at sea such as lifesaving organizations with boats, life vests, Plimsoll lines (to prevent overloading), licensing in an attempt to require competence and, in an epilogue after the Stevensons era, radio, GPS, and EPIRB. Bathurst notes the Volvo phenomenon -- as safety and navigation equipment improves, recreational boaters take greater chances, like Volvo drivers who drive faster because they are lulled into a false sense of safety by the safety built into their vehicles. A cautionary advice to all sailors.

My enjoyment of the book was enhanced by two others I have read. The first half of Robert Louis Stevensens "Kidnapped" is in essence a counterclockwise circumnavigation of Scotland, punctuated by a shipwreck, which, took place on the Isle of Erran, near the site of Skerryvore, the largest, tallest Scottish light.
The wreck was before the light was built. I added the route of the hero of "Kidnapped" to the crude map in my book. The second was Joshua Slocums Sailing Alone Around The World, reviewed in this blog, which included a gift of books from Robert Louis Stevensons widow to Captain Slocum.

The first in the line of Stevensons began as a metal worker who invented polished curved mirrors to concentrate light. He built lighthouses to provide a market for his polished mirrors. He was self taught and valued education and the dynasty grew up coincident with the development of engineering as a profession. He considered himself inferior because of his lack of a classical education.
Here is Robert Louis, painted by his friend, John Singer Sargent, obtained in August 2015 at a show at the Met Museum of  Art.

Many people love lighthouses as works of beauty. Our Maine trip in 2013 has pictures of many of them. And one underestimates the value of lighthouses to navigation if one thinks them as useful only at night. As God led the Children of Israel through the desert for 40 years (Exodus 13) by manifesting himself as a pillar of clouds by day and a pillar of fire by night, lighthouses guide mariners by their light by night and their bulk by day.        A good read.

Working on a July Launch Date for the Optimist

| 0 komentar |
My brothers and I have slowed our building of the Optimist down to a crawl. However, my brother Darren has taken the lead and wants the first boat to launch on July 4th.

He has purchased sail, tiller and extension, blades (rudder, centerboard), gudgeons from APS - Annapolis Performance Sailing.

To protect the chine he has laid down a 2 inch strip of fiberglass cloth in simple-clear polyester resin. It should provide a bit of resistance to any "hard blows" on rocks that make up the shore of our part of Lake Ontario.

Polyester resin is quick to harden and very easy to sand. It costs about half the price of shipping epoxy to us. Its just a short drive to the auto parts to pick up a quart.

Jet Propulsion for hydrofoil or maybe a prop and flex shaft

| 0 komentar |
Very cool control system



The drive with the angle reduced improves losses 20% 4.3 Amps idling so only 300mA losses from the shaft. I think the steering should be integrated as a kitchen rudder behind the prop.




Reversing the shaft on a Turnigy D3542/4 Aero drive It a 1450 KV and should deliver loads of torque at 14,000 RPM on as 3C



Battery: 2~4 Cell /7.4~14.8VRPM: 1450kvMax current: 48A No load current: 4AMax power: 690WInternal resistance: 0.019 ohmWeight: 130g (including connectors)Diameter of shaft: 5mmDimensions: 35x42m



Above is a 47 mm prop I have a 57 to once I have the motor attached to the shaft sleeve I will do a power test in a tank see what thrust and Amps I get. With the fat end of 1 HP it should have plenty of clog to lift  it up on the foils.




The shaft is running in a good quantity of copper slip. Ran it on a 4C for a minute an the brass only got warm.



I think the body of the hydrofoil will be a lunch box. I think I will have the prop shaft attached to the rear foil

Perhaps the prop on the above can be placed in a tube like these designs



An interesting jet outboard very high outlet must cost power




Jet Propulsion for hydrofoil  





One thing as there is no transom the bulky scroll will always be in the flow and the outlet will be under water which will reduce the trust considerably.


If the outlet was up high it would work better also the riser would need to be streamlined







Or what about an EDF pumping air into a venturi like below

2015 Fall Season A List of Free for alls

| 0 komentar |
Over the years this blog has featured some of the oddball regattas/sailing races where you take your oddball small sailboat and compete against a bunch of other oddball small sailboats. During the fall season there is enough of these events you could, if so inclined, hop-scotch up and down the East Coast of the United States.

They are (in roughly chronological order):

Sebago Cup - mid-September at the Sebago Canoe Club, Brooklyn N.Y.
A one race jaunt around Jamaica Bay. Im sure they would be delighted to see some out-of-town visitors and been told, even though this is Brooklyn, there is plenty of parking around the club. See comments for more info from SCC members.

SEBAGO CUP ----- September 19, 2015
Our annual cruising race!
This is an open class cruising race open to non-members. Fleets will be created upon the participation of at least two boats of the same class. Contact sailing@sebagocanoeclub.org for more information.
Skippers meeting - 11:30 am
Starting gun - 12:30 pm
Notice of Race
Sailing Instructions 


NSHOF Classic Wooden Sailboat Rendezvous- mid-September, Annapolis Maryland.
A one-or-two lap race around the Annapolis Harbor. The majority of entrants are classic cruising keelboats but there is always a smattering of small boats. This year John Z is entering his Classic Moth.


CLASSIC WOODEN SAILBOAT RACE, Sunday ---- September 27, 2015
NOR



MASCF (Mid-Atlantic Small Craft Festival) - First weekend in October, St. Michaels Maryland.

This is more of an event than sailing race but there is, on Saturday, a one-lap sailing race in the river starting around noon that is quite a hoot. I have done it twice in my Classic Moth Tweezer where I was racing in a division featuring a motley assortment of larger craft including Thistles, Core Sound 17s, Blue Jays, Celebritys, log canoes.

MASCF ---- October, 2, 3, 4, 2015

Registration






Tweezer trying to stay ahead of a log canoe - MASCF sailing race

Pollys Folly - mid-October, Megunticook Lake, Camden, Maine.

Hosted by John and Polly Hanson. This is a small affair, hosted out of their lake-front cabin around the time of Maines fall foilage.

Archipelago Rally - early-November - Somewhere in the state of Rhode Island.

In a twist on normal advanced scheduling, the organizers wait until about two weeks before the event before announcing the location. A one lap race, usually going around something.

Project on Hold for Summer

| 0 komentar |
We received an email from David Palmer wondering what happened with our projects. Well, summer came along really fast after April 1st. The boats are sitting and waiting for us to pick up our tools again in September when sailboat racing, swimming, golfing, beekeeping, child-rearing, gardening, and goofing-off have slowed somewhat. Although, that child-rearing thing never lets up...

Until then we will continue to sail optis in our dreams.

Optimist News:

From the series Here Come the Optis, by Curt Crain as shown
in Nicholas Hayes web page "Saving Sailing"

  

 Nicholas Hayes book Saving Sailing was a very good read. He also has a web page devoted to the subject. In one of his articles titled, "Opti Haters" he mentions the merits of the Optimists, and he drew some comments, both positive and negative that are interesting to read.

"I am admittedly hard-pressed to say that there are flaws with prams. In fact, I have a hard time criticizing anything that uses foils to make motion from wind. And they’re classically cute" - Nick Hayes

"Why do we have kids learning on a 50 year old platform? Just imagine if you decided to have your kids learn downhill skiing on a pair of 1960 vintage skis." - Reply from Captn Ron

Sewing Machine For Upholstery and Enclosure Canvas

| 0 komentar |
A few years back,my girlfriend and I purchased a 1962 Singer Fashion Mate 237 from my aunt for a song.Soon after,I located an owners manual for the sewing machine on Ebay.Reading through it,I have found that the sewing machine is capable of doing upholstery and canvas sail cloth work.I was a bit surprised that the sewing machine is rated for canvas sailcloth.The sewing machine is heavy,around 80 pounds.I believe the body is cast steel.I know the internals are high quality precision machined steel,possibly hardened.I worked for a friend that did auto,rv,and marine upholstery.His father also owned a household upholstery shop.I worked for him when we didnt have work.At those two shops,I used a Pfaff and a Consew.I briefly had an auto upholstery shop where I leased some off brand sewing machine.It was a horible machine that wouldnt hold its timing and constantly bent or broke needles.Its not fun having a needle fly past your eye at sub light speed.Always wear safety glasses.Sounds goof,I know,but flying needles can be dangerous.Some of the newer industrial commercial machines have clear plastic glass guards to protect the operator.I dont need,nor can I afford,to go with an industrial sewing machine.

Recently,I had been looking into Sailrite sewing machines.I know that when I build my boat,I will want to do all the work I can myself.After viewing some of their sewing machines,I feel confident that my sewing machine will handle the job.I am not knocking Sailrite sewing machines.They are quality.My sewing machine may not have all the options and accessories as a Sailrite,but it is more than enough for the simplistic interior and canvas work that will be on my boat.I will have a few seat cushions,interior,and exterior window coverings.I wont have a flybridge to deal with covering and/or enclosing.I will enclose my rear deck.I will have a rack over my rear deck to carry my dinghy.My plan is to hang my canvas from the rack like the old external frame tents used in the 1950s and 60s.It will seal to the back of the cabin with a belt rail system similar to those used on Jeep CJs and Wranglers.All in all,there wont be as much sewing on my boat compared to something like a Bayliner of comparable dimensions.


Here are some pictures of my sewing machine.It came with a beat up cheapo cabinet.I will build a small table to set it in when I get ready to do the upholstery for my boat.



Photobucket Here is the cabinet open.The sewing machine nestles down inside of it. Photobucket Lifting the stand allows the sewing machine to rotate up and out of the cabinet. Photobucket Here is the speed control(gas) pedal.It is aluminum with a plastic pedal. Photobucket Here is the machine rotated up out of the cabinet.You can see all the precision steel machine work.Also visible is the date stamp,8162 or August 1,1962. Photobucket This machine has a lot more options than first appears.About 60 different ways to set up for sewing.It will even do embroidery and buttons.Thats gotta be useful. Photobucket Here is a picture of the built in light and the motor.Dont be fooled by the motors compact size,it got some power. Photobucket

Optimist Gunwale looking for the perfect design

| 0 komentar |
Thinking ahead to the time when we will add the gunwales (gunnels) has got my mind racing. I remember dinghies I sailed as a kid, and they always seemed to have some sizable gunwales to sit on. Some of the plywood Optimist Prams dont offer much surface area for the helmsmans backside. I know our kids will start out in light wind conditions, but it wont take long for them to want to sit on the high-side and hike while sailing.

In my searching for the best solution for this design I looked at the Club Racer by Bateau. They seem to have a comfy looking gunwale, so I looked into the way they created their version. A complete guide to the construction of the Club Racer is located at: http://www.latitude2739.com/club-racer.asp It is a really nice looking Optimist that is the same as the epoxy/wood version of the Optimist as described by the IODA standards. Bateau claims that it differs in that it is much easier to build and will be more durable, and last longer.

They start their process with corner braces cut at angles to the sides and bows to create the width that will be the gunwale. Plywood is used for this process, but I think we could use hardwood to accomplish this same design using glues and screws to bypassing the need to encase the area in epoxy.
All photos - Youth Sailing Foundation of Indian River unless otherwise noted.


To build up the width of the gunwale on the sides of the boat, they employ the use of plywood spacers to hold off the inner strake that will define the inner side of the gunwale. The picture below shows a double piece of 12mm plywood used as a spacer along with an inner and outer strake and rubrail of 12mm plywood. I believe that makes a total width of 3 inches.


The bow and transom are finished of in less thick manner shown below:


 

With the substructure of the gunwale finished it looks pretty nice. Ive been contemplating how well this design would look if we finished the gunwales without a cap piece of plywood. The plywood works well in the Club Racer because it will be sealed with epoxy. Our boats will not have epoxy, and this makes the finishing of the gunwale, perhaps a bit different.



The Club Racer is finished off with a plywood cap piece set in thickened epoxy, and then the edge is routed to 5mm radius for comfort and esthetics.



All this great information and pictures came from the Youth Sailing Foundation of Indian River Co. and their sister site Latitude 27/39 Sail Club.
