The blue boat on the right of the picture is Zeeslang, now restored and in Austria!
Visit the Dusseldorf Boat Show in Germany right now to see her.

I took this picture from the decks of Brer Terrapin some while before we sailed to Salvador, Bahia, Brasil in her.

DS 15 Sport boat kits

We now have the cut files to this new and exciting design.

Plywood okoume marine is ex stock and we can cut to your order in a short time.


Prices on materials are based on the 2013 last import price, the Rand has fallen in value, so new stocks will cost more to those buying in Rands, those buying in U$ or other offshore currencies will find the cost of a kit to be low, about U$1194 at todays costings.

 
My thanks to the Dix Design web site for the pictures.
 
 
Plans are an extra, we offer a discount on the plans when the kit and plans are purchased at the same time.
 
Shipping world wide is normal for us.

Safety Electronics Leader’s Virtual AIS Beacon Greatly Enhances Public Safety at World Class Sailing Event

Auckland, New Zealand Vesper Marine, a leading manufacturer of innovative marine safety products, announced today that its Virtual AIS Beacon for Aids to Navigation has been selected by the America’s Cup Event Authority to provide critical safety information at the Louis Vuitton challenger series and the 34th AC Finals held this September on San Francisco Bay. A truly innovative technology, the Vesper Marine Virtual AIS Beacon will be used to establish a Virtual Aid to Navigation perimeter that clearly outlines the racecourse the for AC event. Broadcast using the international standardized marine Automatic Identification System (AIS), changes to the course can be made in real time ensuring the ultimate in safety for spectators and other local San Francisco marine traffic.
Complementing a private system already used by AC organizers to manage the race and notify race boats of approaching boundaries, Vesper Marine’s technology has been implanted to address safety concerns for on-the-water spectators and general marine traffic that uses the busy waterway. Authorized race officials will collect real time information from race marshals, calculate condition-dependent course boundaries and, using Vesper Marine’s application programming interface (API), send information to the beacon automatically. The beacon will establish a virtual fence around the course and broadcast this information to the public using AIS frequencies, essentially painting the course on surrounding vessels’ dedicated AIS displays and navigation systems to clearly outline boundaries and other critical safety information. As a result, spectator and official vessels can quickly and easily see their own positions relative to the course boundaries on their navigation displays to ensure they are safely outside the course at all times.
“Vesper Marine's Virtual AIS Beacon proved its worth during the 2012 America’s Cup World Series races on San Francisco Bay allowing America’s Cup Race Management to communicate the location of the race boundaries,” said Stan Honey, director of technology for the 34th America’s Cup and one of the inventors of televised football’s ‘first-down’ technology. “We used it to broadcast the location of the boundaries around the racecourse to the spectator fleet, similar to the way we use graphic overlays to show the same boundary locations to those enjoying the race on TV. We are confident that Vesper’s technology will continue to greatly improve operations and communications for everyone during the main event!”
As used by the Americas Cup to track their boats.

Even I did not know that!

TBA and the RCYC in 1994

The founding of the very first Wooden and Classic Yacht Regatta and the TBA Easter Classic Boat Regatta was just one week apart, the RCYC was first and next was the TBA, we joined forces the next year and it stayed as a very good relationship for the next twenty years, what happened, you tell me!

 

Click on the page, dated March 1994 so nearly two decades ago. Signed by the late Capt, Peter Moon.

 
The two Commodores, RCYC Commodore Dale Cushner welcomes the TBA, while past TBA Commodore smiles and toasts with a glass of wine. Dale told me later he was very surprised that the Traditional Boat Asscociation was closing its doors, I told him So am I!

We even had the last TBA meeting ever to be held at the RCYC last year, the place was a full house affair. The RCYC commodore told me he and his committee will back a revival of the TBA if we can find the persons to drive it, any takers out there?


My thanks to our wonderful RCYC hosts for many years and this last evening when they laid on a spread of snacks we can only dream of.

Mirror Dinghy rudders and foils

You will require one each per boat but I guess its best to carry spares?

We have a first order to produce some Rudders and they may be ready early February, Foils will follow as we will CNC cut both at the same time.


My thanks to whoever took this really good picture! click on it to enlarge.

We are adding a margin of strength with a GRP inner core, laminated with epoxy.

Contact me for prices and orders.

SWG what does this mean?

I needed a quote for a British car part being manufactured, the drawing I have is marked as
using 16swg steel plate.

SWG
n
1. (Metallurgy) Standard Wire Gauge; a notation for the diameters of metal rods or thickness of metal sheet ranging from 16 mm to 0.02 mm or from 0.5 inch to 0.001 inch
 
In real terms, well in Metric this is around 1.6mm thick.
 
 
 
The Sunbeam Imp Sport oil cooler mounts are the parts being remade.

My digital micrometer gave me a reading around 1.68mm thick, the paint makes for the extra thickness?
 

Always learning?

Standard wire gauge

From Wikipedia, the free encyclopedia


A standard wire gauge.
British Standard Wire Gauge is a set of wire sizes given by BS 3737:1964 (now withdrawn), and is generally abbreviated to SWG. It is also known as: Imperial Wire Gauge or British Standard Gauge. Use of SWG sizes has fallen greatly in popularity, but is still used as a measure of thickness in guitar strings and some electrical wire. Cross sectional area in square millimetres is now a more popular size measurement. The current British Standard for metallic materials such as wire and sheet is BS 6722:1986, which is a solely metric standard.
SWG was fixed by Order of Council August 23, 1883. It was constructed by improving the Birmingham Wire Gauge. It was made legal standard March 1, 1884 by the British Board of Trade.
The basis of the system is the mil, or 0.001 in. No. 7/0, the largest size, is 0.50 in. (500 mils or 12.7 mm) in diameter, and the smallest, No. 50, is 0.001 in. (1 mil or about 25 ┬Ám) in diameter. Between each gauge, the weight diminishes by approximately 20%. Because the weight per unit length is related to the area, and therefore the square of the diameter, the diameter diminishes by approximately 10.6%:
\mbox{Diameter Ratio} = 1-(1-0.2)^{\frac{1}{2}} \approx 10.6%

A table of wire gauges and diameters is shown below.[1][2] The relationship of diameter to gauge is piecewise linear, only approximating a (constant-ratio) exponential curve.

A world first, Mirror Dinghy kits to be CNC cut in South Africa

Mirror Dinghy news:

At the 2013 Mirror Worlds held on Lough Derg, N. Ireland, South African's Ryan & Michaela Robinson where crowned World Champions!
Lough Derg Yacht Club in Dromineer, North Tipperary, hosted the 2013 Mirror World Sailing Championship, the first world sailing championship to be held on the inland waters of Ireland.

I note that the South African world champions won in the plywood / epoxy version of the Mirror Dinghy class, well done to both of you!

Note, both the Ply/Epoxy and the GRP boats need to have a minimum weight of 45.5 kgs, so there is no difference between either.  Corrector weights to 3.0kg are allowed, once placed and fixed at the thwart, they are marked and become part of the boats measurement certificate.

Unknown to myself, I was informed only yesterday that when we start CNC cutting our Mirror Dinghy kits we will become the fist such company or person to such a thing.

What a privilege!

50 years of the Mirror Dinghy

Please order your Mirror kit now, we are taking in plywood stocks to ensure we can meet the demand prior to the Mirror Worlds here in January 2015.

Cutting a Mirror Dinghy kit with a CNC machine has as yet never been done, so we will be the first to offer such accuracy, meaning each and every Mirror kit we sell will be the same.
Roy
The Mirror dinghy, the little plywood wonder that brought sailing to the masses, is still loved today by some of our best-known sailors.
Olympic medallist Stuart Bithell learned to sail in a Mirror. Round-the-world yachtswomen Ellen MacArthur and Dee Caffari are big fans too.  And this year the Mirror dinghy, the little plywood wonder that brought sailing to the masses and launched the careers of some of our top sailors, is 50 years old.  Last summer Stuart, now 25, claimed Olympic silver in the 470 class.

Historic Table Bay Sailing

A request for information on a picture of yachts sailing on Table Bay, Cape Town has just come in.
I would guess mid 1950s to 1960??

Hi

Attached is a photo that was found by a friend of mine in the SAR (South African Railways) archives. I wonder if you may know the class and approximate date when this would have been.

 
Thanks
Andy

 

Click on the picture to enlarge it, what a fine shot!

My reply is below:

Note: I now believe the boat in the center to be Caprice, built here in Cape Town by Lowe and Halverson and owned by the late Jerrold Salaman, can anyone confirm this?

Both of the yachts below were owned by Jerrold, as were others.

Read here to see his obituary: http://rcyc.co.za/sailing-news/jerrold-salaman

  “Caprice” – 39 foot Gaff Cutter

                                         “Windward” – 42 foot Gaff Cutter designed by N D Ross,      

                                         built by Louw and Halvorsen in Cape Town

Andy,

 
Thanks on the picture, its really a fine shot and one I have not yet seen?

The boat center to the picture may be St George, the Maritime Museum had her as a static display some years back, I supplied the materials for her reconstruction.

The larger yacht to the right will be Halloween, she was restored by the Stremple brothers about 15 years back, I supplied all the wood and ply. They then sailed her to Brasil, then onto Spain where she was  sold.

I may find the yacht on the left in my book on the history of the RCYC, I will have a look and let you know if I find it?

Any more such pictures?

Regards

Roy


I took this picture, also in Table Bay but many years later and an Easter TBA meeting, circa 1998 or thereabout?

Note that Haloween has been converted to a more traditional gaff rig, Ren Penso was not happy when she heard the new that Karl Stremple was going this route but by then Haloween was a near wreck and any care was to be credited. In the end the boat was more or less rebuilt and to a very high standard. This included new decks, masts and spars, all birdsmouth constructed, I supplied the Oregon pine to that work, the teak to the decks also.

Mirror Dinghy kit supplier in Southern Africa

For some while now and very much behind the scenes we have been discussing the possibility of CKD Boats cc of Hout Bay near  Cape Town, South Africa becoming the official ISAF recognised Mirror Dinghy kit suppliers to South Africa and other countries.


Todays inter class dinghy show was held at the Zeekoevlei Yacht Club, well attended many got to meet the class leaders and in some cases the boat builders also.


Click on the picture for a larger image.

We will soon start the construction of our hull # 1, this needs to be measured for proof that we have CNC cut the boats shape correctly, when this is proven we will be offering the Mirror Dinghy in a number of options.


A well campaigned wood epoxy Mirror Dinghy transom.

 
CKD Boats cc will offer the wood epoxy boat as a number of options.
 
A base kit with the CNC cut okoume marine ply to BS 1088, wood, epoxy and glass tapes only, the kit pre assembled but not finished , or the boat finished to the stage you require.
 
Options this way will suit most pockets.


Exciting news!

WPMC Historics is back!

We missed this event in 2013 as the costs were said to be too large and the Cape Town Western Province Motor Club declined to have the cars that year, now they are back for 2014.


Entry was R80 per person in 2012, expect similar or a little more but the value is worth every cent.

See you there, best to be early so you can really see the cars close up and meet the drivers. Take sunscreen and a hat to cover your head and neck, the sun can really get you over the period of an entire day.

Roy
 

Small boats show today!

For those in the Cape Town area, you can see a display of various dinghy classes today and at the Zeekoevlei Yacht Club, it opens at 9am and runs to 2pm, see you there this morning!


This is the Mirror Dinghy, the file picture is named Wirrel Ark Dinghy, Wirrel is a town near Birkenhead, Merseyside.


 
The same class of boat and under spinnaker
 
Looks like fun.
