With friends and their yachts sailing off right now to Brasil,this is a good time to post a picture I took,its in 1977,we are with the crew of two other boats,one is the Eckhoffs,Donella,the other is a family from Durban but I do not recall their family name or the name of the boat,it was about 36ft long and a pale blue.Dennis off Brer Terrapin is standing up and suggesting our plan of action for an evening ashore and a beach braai.The camera was my Canon FT with a 1.4 x 50mm lens.

Actually,its no laughing matter but maybe some of the world powers are a joke?

Vampire Jets

We have a second order to supply Hendrick with our Resolution 816 epoxy and 205 cure agent,while the plane may fly,its construction is wood being in plywood made from birch,so when we think of it,planes and yachts are very similar,they both fly in one way or another!

The Vampire Jet designed by de Havilland, Hatfield. Some 1500 were built at English Electric Preston in the 1940's.

Design and development

Interior layout of the Vampire FB Mk2The Vampire was considered to be a largely experimental design due to its unorthodox arrangement and the use of a single engine, unlike the Gloster Meteor which was always specified for production. The low-powered early British jet engines meant that only twin-engine aircraft designs were considered practical; but as more powerful engines were developed, particularly Frank Halford's H.1 (later known as the Goblin), a single-engined jet fighter became more viable. De Havilland were approached to produce an airframe for the H.1, and their first design, the DH.99, was an all-metal, twin-boom, tricycle undercarriage aircraft armed with four cannons. The use of a twin boom (similar to that of the Lockheed P-38) kept the jet pipe short which avoided the power loss of a long pipe that would have been needed in a conventional fuselage. The DH.99 was modified to a mixed wood and metal construction in light of Ministry of Aircraft Production recommendations, and the design was renumbered to DH.100 by November 1941.[2]

Under specification E.6/41 for two prototypes, design work on the DH.100 began at the de Havilland works at Hatfield in mid-1942, two years after the Meteor.[3]

The Moth hydrofoil

We have been asked to develop a Moth hydrofoil kit,whats a Moth says I,checking on the web I see its nothing new but they can be expensive,exciting too I bet.We have asked one of our team of designers to give the idea some thought,its a possible thing,so watch this space,as the kit will not be expensive,there is so little boat!

Flying Cloud,a Dix Design Dix 43

How big is a big boat,there probably is no answer to that but the 45ft american yacht that used this cradle before this boat, sure looked a whole lot larger than this Dix 43!We have boats on our kits offerings to 55ft but size is not an issue really.
Left click the picture to view full size,the camera was a Canon G11 set on auto.

This was not a boat built from a kit,it was hand lofted and hand built,the hull took me six weeks working eight hours a day to build.It was the learning curve on Dudleys radius chine construction start though,so in some ways the beginnning of what became to be known as CKD Boats cc.We can offer CNC cut bulkheads on this design,also the very similar shaped Dix 38 and 45.

SSB Radio ground plates

The issue on a boat of a decent SSB ground plate always causes discussion,I can only advise what has worked on my own boats and worked very well,the basics are a decent radio of course,then a copper foil to ground it with (not a wire) you then link up to various things that will help the cause,steel tanks and the engine are a good start.In my case I have always had a copper plate with a large slab anode fastened to it,not so neat but it works very well and as the engine is connected to the anode,I have never ever had any worry with corrosion in the engine,so its working two ways in my case.I have just added an upgrade in a dynaplate,thats the bright yellow slab next to the anode you can see,its a mass of bronze balls sintered together to make a connected mass,but not solid,you can blow air through it,the size you see is said to equall five (5) square meters of ground plane,I should have a very good set up now!

Inside the boat,one of two mounting bolts on the dynaplate,the brass shim foil goes to the anode stud which is out of sight under the pipe work,the anode stud already has a 3" (75mm) copper foil ground strip in place.Why the brass strip? I have run out of copper but have brass shim stock,its the same thickness so I used that.

The copper plate is about 550mm x 550mm,it will get some growth on it but not much.

Insulation,Alububble sheeting

I had recently removed the boats head liners to do some other work,so I used the chance to spray them with a twin pack satin clear laquer,a decision to install thermal insualation was taken too.What type and where from was a small problem,the aft cabin has 20mm polyurethane foam sheeting,it works well but does require cutting and makes a bit of a mess,it also needs a full coating of contact glue,so a lot of work. A chance conversation on the subject with Andre,one of our valued customers, had him deliver 4m2 of Alububble insulation to me to try out,he had bought an entire roll for his Sadler 32 new boat fit out.

Using this product is a great experiance,its easy to use,cuts with a Stanley knife,makes no mess and requires just a narrow application of contact glue around the edges only.Being just 3mm thick I was able to use the headliner as my template,cut and glue,then screw back in place,what a nice product,recomended!

With all head liners back in place and most of the teakwood trims screwed back as well we are nearly finished,I sense a nicer audio sound from those two Pioneer radio speakers too.

We can make these hatch trims to order,either just the corners and you make your own frame,or completed and ready to fit,we stock round air vent trim rings in teak wood too.

Look closely,you can just see the edge of the insulation material on top of the plywood headliner,the air space is an important part of why it works by the way,always install with the silver foil upwards.

The silver side up,this panel is glued and ready to install.
Warning,if using contact glues or similar,always have lots of ventilation available,with no naked flame or smoking allowed.

Sigmacover 525 tie coat application

What started out for me as a very large problem became a walk in the park when a proffesional team was assigned to me for the day,the idea was to get UHP water blasting known about In Hout Bay,for which CKD Boats are now your contact agents but the company who do this work can and do travel country wide,in fact the entire southern africa,so if you need a quality job please contact me at roy@ckdboats.com or Cape Town phone number 021 510-7206 for more information.

Sigmacover 525 tie coat can be overcoated in twelve hours up to a maximum of fourteen days,it has properties that bond with the next coat,which in my case was to be antifoul.
Left click all pictures to view full size and see the full details.

With a second coat applied we have the perfect finish,in twelve hours we can apply the antifouls.

The first coat will not give a full cover,the second coat does that with ease.


Using a fine mo-hair roller I applied the first coat of Sigmacover 525,its really important to get a 100% cover,no pin holes,nothing is allowed.

The suppliers of the paint told me that even after a 12 hour period had elapsed,even fresh paint needs a good hand wash with soapy water to remove 'contaminates' or airbourne dust and salts that may have blown in,we used a small amount of Teepol in fresh water,do not use washing up liquid,its additives could cause bother themselves.When washd,hose off ,then allow to dry fully before continuing the paint process.

At this stage we (me) have applied two full coats of Sigma etch primer,the cure period is a full 12 hours,so in my case the next day before overcoating with Sigmacover 525 tie coat was possible.

Sigma Primer on a UHP cleaned steel surface

If you want to blast your steel boat,keel or rudder with no mess other than water run off,read on.

The blasting process is beneath the blog on cruising in Saldhana,to follow is the overcoating with Sigmacover 525,then application of Interspeed antifouls,left click any picture to view full size and see more details.
The holes were cleaned out the following day and welded over,then a new coat of Sigma primer was applied over the new steel weld,prior to two coats of Sigmacover 525tie coat.

South African Cruising destinations

There are few places nicer than the Saldhana Yacht Club,its about 62 miles north of Cape Town.Thats baby Janet,with her mother Jean and Wally Hemmens having a chat early one morning.The boat is Ocean Planet,an Endurance 37 and our first yacht.

Flying Clouds steel keel box UHP water blasting

With such high pressure care must be taken to ensure safety,over blasting of other boats is not however a hazard,the water only has intense pressure up to about 40mm from the nozel tip,then it looses its high power very quickly.




A full technical team was sent to evaluate the job,nothing is left to chance,the Sigma primer paint was even applied by the same team.

The ultra high pressure pump,this uses only water and runs at a pressure of some 2000 bars,the job was to remove the paints and rust from my steel keel shoe,the job took about three and a half hours,thats about eleven coats of paints (ten years worth) plus any rust.

When a diver who was changing a propellor shaft anode said the keel anode is missing,we knew trouble was ahead,why the anode had gone is open to discussion,other boats have had bothers too,it may be an electrical thing.

Bruces Dixi Dinghy Build

Bruce has made fine progress on the build of our kit,its close to being ready to paint or varnish I think,the dixy dinghy is our most cost effective dinghy as it comes out of just two sheets of ockume marine grade 6mm ply,as a good load bearer its an ideal tender that can either row,motor or sail.

Hout Bay Harbours Travel Lift in action

Where is this Travel Lift,its a 40 tonner by the way,well my Garmin GPS says we stopped at this position, S 34 03 132' and E 18 20 722' but dont take my word for it,check before you use those positions,basically its a hard turn left when you enter Hout Bay Harbour mouth,then head for the center mole on the far side of the harbour,the slip is on the right side of the mole on the far end.

This is Flying Cloud our Dix 43 being lifted by the travel lift in the Hout Bay Boat Yards facility,run by Warren and his crew,its a very pro opperation I can recomend.

Foxy Lady,the Zeeslang connection.

We can easily produce a bulkhead and frame set to this design if required but it will not 'measure' as the original boats had wood frames,not CNC cut marine plys we would offer,the boat will be lighter in wood epoxy though,so faster.

A Royal Cape One Design (RCOD) at speed,thanks for the words and picture Chris.

Hi Roy - I still own Foxy Lady which is a fibreglass RCOD. And yes these little boats still go like smoke. During the 2008 Vasco we regularly surfed at speeds of 18 kts. After the race the log and gps showed max speeds of 22 and 23.5 kts respectively. Neither of the drivers remembers achieving this speed but we may have been too busy watching the spinnaker leech to think about the log. We sailed a there and back race on Sunday ( abt 14 nm ) and finished first over the line and handicap. Although Foxy is for sale ( I have to sell her to finace refurbishing my Morgan 31 ) I cannot think of a better budget boat for the Sa coast. Her replacement, the L26 is a good boat, but you cant do ocean passages on one. As you probably know Suidoos II has 4 Atlantic crossings under her keel ( 2 South Atlantic Races from which she returned on her own bottom ).

Cheers

Chris

One design class boats in miniture

Colin Farlam is well known as the historian for the RCYC here in Cape Town,he is also known for his success in promotion as 'Colin Farlam Yachts', he makes and sells complete boats and also kits he can send by post. The GRP hull he is holding weighs just 3kgs,even when he has fitted bulkheads and decks using our epoxies and plys, the boat will weigh little more.

The boats design is a Sparkman and Stevens, each hull or kit Colin sells carries a certificate and a hull number prooving the design and royalty fee as paid the the designers, contact me at kits at comlumber.com for more information.

The roll of wood on wood mahogany veneer will be laminated to make a super thin modeling ply, it will be around 2mm when bonded,this makes a light ply suitable to deck the GRP one design model with, its waterproof.


February 8th, 2013:

Colins neice has just phoned me with the sad news that Colin has recently passed on.
Colin was our link with the past, he knew so much about the yachts and boats in Cape Town.

R.I.P Colin.
