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.

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?


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.

Superform bending plywood samples are ready for you

So are the flyers which I can easily email to you on request.

We also have some cross grain samples prepared also, in 3mm 5mm and 8mm thick.
There are now seven outlets in the Cape Town area, contact me for the closest one to you.


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.



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.

(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.


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,



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 ( ) . 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.

Click on the picture for a full size view.

We are taking orders now for a new shipment in October.


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!

The Proteus 106 sailing catamaran has been re costed with surprising results!

We have been watching with ever larger eyes the rise in the cost of the BS1088 Okoume marine plywood, eventually we have reached the stage that the cost is what may be seen as too high?

Rick in Thailand sailing his own version of the Proteus 106, which has extended transoms with rudders under them.This boat was built from plans and not from a kit.

So we checked the prices and weights of the BS1088 Redwood plys, saw that price wise we were on a winner,then checked  with various yacht designers and asked can we use the Redwood plys on their kits?

In the case of the Proteus 106 catamaran, Angelo Lavranos came back and told us that the plys he used for calculations were 10% heavier than the okoume marine, so the Redwood would be fine for his design.

Using a really sharp pencil we work out the plys only kit and with the MDF removable stations panels included, plus the CNC works required on all 121 panels, we can now offer the panels kit for just R98,000 plus Vat for local buyers.

There is no Vat on exports, allow U$9949 for the kit at todays exchange rate (17/09/2013)

Plans are extra and cost NZ$4300 which are supplied direct from the designer.

There is a highly skilled wooden boat builder here in Cape Town who has done costings to build this boat to an in the water price. let me know if you need his contact details, you could be on the water for less than you think!


Clinker built Tammie Norrie rowing boat

This boat was made from some 6mm okoume marine plywood we supplied.
The jigs were in 12mm pine ply and worked out inexpensive, doing the job just fine.

The CNC cut files were supplied by Alex Jordan in the UK, we can cut more under licence to Alec.
While the plans are by Ian Oughtred.

Even with the row of clamps on the side rails, the boat still feels quite light.

A suitable pair of spoon oars will me made especially for this boat.


Your Superform bending ply importers

We will soon have a distribution map on our main web pages at
 the map will show you where to find a store selling Superform bending plywood. If you see that there is not a store near you,please advise and we will see if we can appoint an outlet near you.

Check the pictures, just some of the yachts we have supplied can be seen in them.

There are a number of new products too, Teak and Holly floor laminate, Stone Form and Lamiform, samples and prices on application. We will be re stocking the Deluxe Light Ply when the next delivery arrives.



New re sellers in South Africa are required, why not put your own companies name and place on our map.

B & G Network instrument pod made using Superform bending plywood

Some write it as BandG, the full name being  Brookes and Gatehouse, nice gear, even the older and used Network ones in the display below.

Making corners has been a way of life since I started importing bending plywood.
Each year I get the local tecnikon students asking for advice on how to use it, I tell them the same each time.

Use it yourself and find out how much it will bend to see how flexible and strong it is? yes, its also waterproof and CE aprooved.

The side, corner and top panel of the instrument display panel,  were made from one long strip of 8mm
thick Superform plywood (honest) you do have to tease 8mm ply around such a tight radius but as we can
see its quite possible.

The use of 5mm thick Superform bending ply would have made the job easier,
 I just happened not to have 5mm thick off cuts that day.

Try it and see, then you tell me.

Easy or what!


Superform bending plywood retail sellers required

We have Imported bending plys for close on twenty years (20) and as a result probably know more about the product than anyone else in South Africa, both as sellers and users, we can advise you on most applications.

Click on the pictures to enlarge the image.

With a new order about to be placed and with some stocks here already, we are looking for suitable board stores and timber outlets to become stockists.

We can email you an up to date PDF on the product, please contact me at roy@ckdboats (dot) or on
27 (021) 790-3859 phone and fax line.

We can offer thicknesses in 3mm, 5mm , 8mm and grain directions both long and cross grain.

For retail we expect an order of at least a pack lot, packs are around 460mm high x 1.23 mtrs x 2.45mtrs.

 The AriesVane Gear mount was also made with Superform bending ply.

These pictures are just some details of a yacht built using Superform bending plywood in Cape Town, South Africa. It is waterproof and also CE approoved, so suitable for both your local and export orders.

 A 3mm pack holds 150 pcs, a 5mm pack 95 pcs and the 8mm pack 55 pcs, we can prepare mixed packs at an extra handling charge.

Delivery country wide by our courier or your own transport.


Great times, teak grating

Not for all yachts but many will have a much nicer cockpit when real teak floor grates are fitted.

Click on the picture for a much larger image!

These are around twelve years old now and have just been in for a service and sanding clean.
They fit around a center cockpit steering wheel  pedestal.

We have some nice kiln dried solid teak in stock and can make to your order.We would need your cockpit sole template, in stiff card works fine. Allow a month for completion, plus delivery time.

While machines are used it can still be said these are hand made, there is no CNC machine work used on this type of work.

They will be fine now for a good number of years, a clean with oxalic acid twice a year can keep them clean.

Note the use of Superform bending plywood in this cockpit.


A special offer on the Optimist kit

Plywood prices have been sky rocketing, so much so that the importers of okoume  marine plys have now refused to being more in due to the fact its costing too much.

If we use the imported Redwood Marine ply, CNC cut it to size we can offer you an Optimist plywood pack for just R2619, plus Vat for local buyers.

The kit will require some wood which you can source yourself, we can supply the epoxy, glass tapes and fillers, plus the builders jig and 14 page assembly guide at an extra cost.

Note, the Redwood Marine ply Optimist will not measure for the Optimist rules due to the plys being outside their rules book, it will however get your kids out on the water and at a far lower cost!


Argie 10 and 15 Kit prices slashed!

With the lack of a quality okoume marine ply available to us at this time, plus its ever rising cost, we have no choice but  to now price our boat kits in Redwood Marine plys.

An indication on what some of the Dix Design dinghy range will now cost is below.

Dixi Dinghy  R1472

Argie 10        R2183

Argie 15        R4136  , with the side seats option add R1302

These prices include the ply sheets required plus all the CNC work to cut the plys to the required shape, this is a price beater and the best offer you will find.

Prices exclude the plans which we have ex stock, the wood we expect the buyer to source where you are,  epoxy, glass tapes and fillers are not included but can be supplied at an extra cost.

For South Africn residents please add R14% vat to our prices.

The option to cut in either okoume or deluxe light ply will be given when we have stocks.
