A small boats main sail SA1 with a trident logo?

This one has me stumped, it was being measured then folded for storage yesterday, there was no sail makers lable on the sail and this far no one recognises the red sort of trident logo, do you?

SA I was of course the sail number given to Voortrekker but this sail is far too small for a 50ft yacht, even when she had the mizzen and was yawl rigged.

SA1 such a famous number but why is it on this small sail?

What class of yacht does this represent?

Does anyone know?

Roy

There was much interest in this topic but  I was not able to find an answer until an email arrived, check the link. http://ckdboats.blogspot.com/2013/09/frans-loots-has-answer.html

Of course that logo is the Greek letter “Psi” so perhaps the Class was called PSI ?

Alloy yacht kit set yacht ready to cut

Contact me for more information, there is a 9.9mtr chined monohull sail boat and a  13.80 sailing catamaran.

We can offer either as a CNC kit set in alloy.

From the designer.

Roy if you remember I asked whether you were prepared to offer aluminium CNC kits, whether you could adapt your cutter to do so?  In this country we do it on 6.10m x 1.830 sheets.  

I have two stock “cut file” designs ready to roll. One is a 10m hard chine alloy cruiser ( a “minimum” high latitude “go anywhere” boat), developed from my Seashirl/Isabella steel 31 footer for serious ocean cruising and the other is an aluminium cat similar to the Proteus 106.

Kind Regards,

Angelo

13.80 METER ALUMINIUM CNC KIT SET  SAILING CATAMARAN
DESIGN BY                LAVRANOS MARINE DESIGN

A lot of family cruising people like the superior space, better live aboard features,  and excellent (trade wind) reaching performance of catamarans, but would like a more damage tolerant  aluminium boat, as opposed to a relatively delicate GRP sandwich which is the norm. With careful design, it is possible to avoid increased weight and reduced performance, using aluminium, while still being compliant with classification society structural criteria.  Additionally this design can be assembled by a relatively inexpensive commercial aluminium fabricator, having simple conic “wrap-able” curvature, multi chine, using  a complete CNC  cut “kitset”.  This brings the cost quite close to that of a GRP production hull/deck.  The hull form is similar to my successful smaller kit set “Proteus” design.  This boat represents the optimum point where the boat is big enough to be “light” even though built in aluminium, but small enough to be easily handled two up, as a family boat. She is also the minimum size for a true “live aboard” cruiser.  At present the design has a four cabin “charter” layout, but other layouts are possible.  Also very shallow draft dagger boards are incorporated, but fixed mini keels is also an available alternative.

The Smoke that Thunders

This of course can only mean one place, Victoria Falls, Zambia in Africa, that's where the JoLon Imp, with drivers Terence and Geoff were.

Terence is writing a book on their trip, below is a short part of that book, if we pre order I wonder can we get signed copies?

Roy

 Our relative easy drive to Livingstone got us to the SMOKE THAT THUNDERS (Victoria Falls) early afternoon and we immediately scooted off up a dirt road following signs to the promise of a camp site where we planned to spend the night.

At first the road was wide dry and gravelly, narrowing as we progressed up the ever steepening climb. Within a few short kilometers the gravel turned to menacingly sharp rock formations that became frightfully uneven making the driving extremely challenging to put it mildly. I had frightful thoughts of having one or more of our tyres slash burst by the razor sharp track surface or worse, a wrecked spring that would surely have rudely halted our progress!

Typically whenever I began to worry about any aspect of the trip I would rub the side of my head continuously as I drove. In this instance however it was a severe case of nil head massage as I kept both mitts firmly on the wheel with full concentration on the job at hand. I was not sure what was going through Geoff’s mind at this stage but I was seriously super worried about the condition of the track we were negotiating. My mouth had become bone dry and my heart was ribcage rattle thumping until I actually pulled up on a particularly challenging sequence of rock formations that we needed to traverse.

“What’s the matter”? was Geoff’s gentle enquiry.

“I don’t know” I gingerly replied.

“I’m not sure if i like this track too much”.

Do you think we should turn back Geoff asked!

Well was i delighted he even suggested the idea and before another sweat bead could drop from my sopping wet forehead I immediately started to drive up the steep and rocky track pulling the Imp to the side of the narrow track so that we could engineer a three point (or as it turned out, a seven point) turn. Remember this was executed without reverse gear! The Imp had to be manhandled by both of us and all the time petrol was liberally spilling out of our overflow pipes due the acute angle of the car and the extreme heat of the fuel tanks due to the front radiator pumping serious heat onto them from early morning until bedtime each day!

It must have taken us a good fifteen minutes, a lot of jumping in and out of the car and more huffing and puffing than any three little piggies’ big bad wolf had ever employed to actually get the Imp facing down this treacherous and uneven rocky incline. Then of course we had to again pass over the horrible surface that had scricked me in the first place! At least the surface got better as we descended and we were again in the hands of an accomplished off-road driver in Geoff. I was a bundle of nerves for fear of damaging the car and that we had no spare cash to repair it if it needed fixing nor the time in our pockets to hang around fixing either.

Shortly and happily we got back to the tar roads of Livingstone where we again went in search of a campsite for the night.

Little did we know that the dirt track experience was just a tiny titbit of the real deal that would finally unfold in Kenya with the added conundrum of unseasonably heavy rains and road conditions that made the Livingstone dirt road experience seem like a walk in the park by comparison. The only difference however, a massive difference was that in the Kenyan situation there was no opportunity to backtrack!

The JoLon guys will be on TV tommorrow morning

Words by TT better known as Terence Tracey who with Geoff Biermann drove a 41 year old Hillman Imp from JoBurg, South Africa to Coventry in just 29 days, that's all 14,000 kilometres by the way. plus a few thousand more on various ferries. They went across three continents, traveled in around 19 countries, some of which they never even stopped in!

The engine in that car was an old Mk1 unit he had lying round, seems its 49 to 50 years old?

Can I tune my TV to that station while in Cape Town is the question?

The SA Yacht blog speaks about the Proteus 106

Which means Justin Phillips of course, check out what he sees and thinks about this design.

http://sayachts.blogspot.com/2013/09/proteus-106.html

One of our kits under construction in Venezuela, note the way its built the right way up, that's a pleasure to work on and in.

Justins SA BlogSpot is now finding use when prospective buyers of South African built boats are finding new owners. I have just used it myself and for a buyer who asks about the Didi 34, try
it and see for yourself.

A new Newel post wanted anyone?

I have been wanting to install a balustrade and lower newel post for ages, the thing never got off the ground as Jean does not want them.

Yesterday she changed her mind and this is what she wants.

Does anyone want to buy my imported newel post and turned rails?

Roy

In historic homes, it is believed that the house plans were placed in the newel upon completion of the house before the newel was capped.

This i 550 sailing skiff just needs the deck laying completing

The pictures arrived today and with a request on paint application. I  suggested using Intergard epoxy primer, a product I have used for a long time.

Click on the picture to enlarge it, picture supplied by owner builder Will, many thanks.

I think we sent this i550 kit off last December, knowing that its the builders first boat kit build I would be happy with the progress if it was my boat.

Note, we are now able to supply you kits under licence to Watershed Boats, plans payable direct.

Whirlpool over Somerset West

I may be wrong but is this really a Cloudpool?

Whatever it is Tojan who has just shown me this picture, says in all his years as a commercial airline pilot
he has never seen anything like this.

The picture was taken by Brent Van Zyl, another airline pilot, my thanks to Brent for the use of his picture.

Click on the picture for a larger image.

The date was September 08 2013 and the place was over Somerset West just outside Cape Town, South Africa.

I think its spinning anti clockwise, the same as water will spin when it goes down the plug hole in a sink, thats a Southern Hemisphere thing, up North it will spin clockwise.

Wow!

Roy

An idea from a novice weather man, anyone have the nerve to say he is wrong?

Hi Roy,

 

Interesting photo. I will give my take on it, as a meteorological non-expert (self-opinionated dunce).

 

That is not caused by a low pressure system, as happens with an hurricane or tornado. In those cases the air movement is upward at the centre. If you look carefully at the perimeter of the hole, the edge of the cloud is wrapping from the left down under the edge on the right. Maybe this downward slope is caused by the slope of the foothills below. Also, low pressure systems rotate clockwise in the Southern Hemisphere and anti-clockwise in the Northern Hemisphere. That is rotating in the direction of a high pressure system. But if it were a high pressure rotation then the movement would be outward not inward.

 

I think that is caused by a combination of a convergence layer that is blocking air movement upward and the general air mass movement north-to-south along the Hottentots Holland range. The plains downwind of the Helderberg have set up the anti-clockwise rotation in the form of an eddy just as you would have with a current passing the mouth of a bay setting up a rotational current inside the bay.

 

Regards,

 

DD

(Dudley Dix)

Then Angelo Lavranos sent a comment.

Hi Dudley, Roy,

 

Hello after all this time, Dudley !   I hope life in the US of A is treating you well .

 Just to say I agree with your suggestion, an inversion layer “trapping” the cloudy layer, and that the topographical geometry along with the prevailing direction of the airflow have combined to form that terrific looking vortex.

 

Cheers,
Angelo

Will the Proteus 106 make a good cruising boat?

This came up from a chap yesterday, see in blue below.
My response was that I think 500 liters of water will be fine?

It’s a nice boat for what it is – my only concern may be its lack of weight carrying ability – its astonishingly light at 2.8T (lightweight), can’t exactly add 500 l of water and fuel!! Mind you with a watermaker and some jerry cans it could probably get about a bit….

It’s a uniquely good design for a small cat!

 

Ricks Proteus 106 in Thailand, note he added to the transom and placed the rudders under the boat.
 

Read what the designer says about his boat.

See attached notes explaining everything.  The boat built in Thailand was built very heavy, and the owner added a lot of stuff without ill effect, and it does not seems to have affected the load carrying capabilities . I am not recommending you build heavier though!

 

Kind regards,

Angelo

 

10.6  METER  MULTICHINE  PLYWOOD/GRP   SAILING CATAMARAN

 

This project has been “gestating” on a personal level  for the last 10 years.  My aim is the smallest  family ocean cruising cat, that is to say with sufficient load carrying capacity to do an ocean crossing with a family, of minimum cost, and capable of amateur construction with the minimum of labour and skill. She is also aimed at being a fast, practical & enjoyable boat for local use. She is small enough for easy shorthanded use.  The hull structure is “pre cut” by a CNC cutter as a kitset, or can be cut to plotted templates as a cheaper option if preferred. The Kitset is available from CKD Boats in Cape Town. Their quality is A1 and different ply type options are available. Since wastage is minimised ( much less than hand cutting), and CKD buy much more cheaply than private buyers, one generally finds that the kit costs hardly more than buying the raw material, and then you save hundreds of hours in labour. The boat is set up on ply bulkheads and stringers and the skin is glass taped with epoxy resin along the chines, inside and out, there are no chine logs. The hull & deck is mostly 9mm ply with 12mm in the forward wingdeck and hull bottom forward. The outside is GRP/epoxy sheathed. She is simple, strong, fast, comfortable, cheap and  “unsinkable”.

The interior consists of four berths (two doubles + 2 singles), a saloon  settee,  a practical galley with icebox, and a toilet compartment,  all with standing headroom (1820 under deckstringers) . She is totally functional, and all that is needed for comfort at sea. She is configured with two machinery and keel variations:  A 4 stroke 20HP outboard on a hinging nacelle is fitted for economy, as is tiller steering, with “kick up” rudders. If the motor starts to make trouble it is easily replaced.  I haven’t worked out how many times you can relace it to equal the cost of diesels. Other “choices” in the “gilded lily” approach stretch to installed water tank versus fitted 20 lit container storage. However with the outboard and daggerboard combination, and simplest accommodation gear, we have the fastest boat AND the shallowest draught for the smallest outlay. People lose sight of the fact that comfort at sea revolves round some very simple “basics”, a dry bunk with good ventilation, a place to prepare hot food, a place to sit out of the sun & elements, a private toilet, standing headroom. The rest is “bells & whistles” which all come at a price of increased cost, maintanance, and degrading performance. 

The rig is the simplest possible, with a pair of cap shrouds and headstay triangulated, single diamond.  The sail inventory is essentially a mainsail, a roller furler jib, and a storm jib. Optional:  Genneker.

 

A  first class builder estimates 1600 hours, professional hours in a set up boatshop, to unfaired and unpainted hull, deck, joinery stage.  CNC cut kits from CKD Boats in Cape Town, a very experienced company, is available at a really competitive price. Email Roy Mc Bride (roy@comlumber.com ) . Most likely you will find the cost of the CNC kit ( including shipping) is less than a private person is likely to buy  the raw materials, so that the huge labour saving is more or less “free”!

 

Wing deck clearance to DWL (@ displ 3800 kg) is 680mm amidships and 1100mm under the cockpit. The windeck does not extend forward which is most important. Top speed broad reaching in flat water and high wind can be around 18 knots (depending more on one's nerve than anything.) and can average 8 knots on an olympic triangle, powered up in 16-18 knots breeze.  Payload of crew, fuel, water, provisions in addition to the vessel complete (with sailing and safety gear, normal loose outfit and sails) is nominally about 900 kg. This figure could be increased by another 400 or so kg at the beginning of a long voyage if the boat

consciously not "overpressed" when so loaded. The length/beam ratio at datum floatation is 9.07. This offers a good compromise between reasonably slim hulls and good load carrying ability. This is augmented by the additional "flare" developed in the topsides, whereby beam (and waterplane area) increases considerably with increasing immersion.

 

The daggerboard version is more efficient in terms of L/D on the foils. In addition the drag of the daggerboards retracted is zero, whereas the mini keels (both!) continue to offer resistance.  The prod and spars are intended to be aluminium extrusions, whose inertias are specified. 

The design license costs   $4500 New Zealand Dollars per boat  to build.  Drawings are supplied in PDF format.  The templates consist of all frames with shell deduction, stringer cutouts, access cutouts etc shown for hull, deck and superstructure, bow and stern profile, daggerboard, (or alternative keel), kick up rudder.  The design consists of: 18 drawings:  Lines, hydrostatics, full scale templates (+ 12 x A0 sheets), general construction drawing, CNC parts assembly drawings,  CNC parts nesting drawings, arrangement plan and sections, deck arrangement, sail & rigging plan, dagger board & case construction, rudder construction, chain plate details, sundry joint details, doghouse & hatch details, outboard motor hinging nacelle detail, alternative keel detail. Study plans consist of arrangement drawing, deck arrangement, sail & rigging plan. Note: study plans  have all section information omitted (other than one "typical" section.)  The design has been developed to minimise labour hours and high skill requirements and high costs. The only "exotics" involve the external skins of the ply rudders and daggerboards, which are carbon, since the excessive amounts of GRP needed would make control of the shape and avoiding excess weight problematical.

Superform bending plywood technical information

We are told by some that they can also offer bending plywood. Sounds fine until you ask them a few questions.

Such as does the glue line resist water, is it a phenolic glue?

Does your product have a genuine CE approval stamp?

Does your product have as good a finish and bend as well as Superform?

The reply to all of the above is normally NO.

After 20 years in the bending ply manufacture, our suppliers make and sell the best in the world
try it and we think you will agree.

Muriels Munchies in Hout Bay Harbour

I have posted this place before, its a well known meeting spot for the local yachties, local and international.

The venue has just gone through a bit of a revamp, the galley was enlarged and now has lots more space and I am sure the galley staff will be delighted. Plus they have fitted roll down wind covers to keep the breeze  and rain at bay.

This was today and in rather damp weather but its fine inside the covers.

The HBYC club house is just a few paces to the left of the picture, the balcony is your number one spot for a sundowner!
