Hoisting day

January 10, 2017

Now the boat is upright again it is time to hoist some heavy items.

The daggerboard out of the daggerboard case. It was used as a mould for mounting the daggerboardcase slot and since then locked in its position while upside down.

Fairing and painting the mainhull

January 8, 2017

I am very happy with the final appearance of the floats. The paint job is great thanks to the thoroughly preparation and lots of effort in the putty and sanding process. However, the fairing of the hulls with the fairing board was a time consuming and very tough job, to be honest a hell of a job.

With the purchase of two wide flexible filling knives at Flexisander, one 2′ wide (600mm) and the other 4′ wide (1200mm), I now choose for a different approach for filling, fairing and sanding process of the main hull. My goal is to minimize the hard work with the long fairing board and maximize the use of my sanding machines.

The trick is to shape the fairing compound with the long filling knife in one continuous stroke, preventing excess fairing material and when done to not touch it anymore. The next part to shape is the width of the putty knife apart.

After (partly) curing it is the turn for the parts in between. When finished this is the first layer of faring compound. The second layer, which uses much less fairing compound, is thereafter applied in such a way that this is overlapping the first areas. The whole job has been done with the 4″ wide knife which gives a very fair result and minimize excess faring compound.

The use of the random orbital sander with grid 40 sanding paper is now mainly in order to make the surface more smooth. This requires some skill to avoid sanding to deep.

The last step is the overall fairing with the long flexible faring board. As the hull is already very fair this is not much work anymore.

My last step of the fairing process is applying one final layer of a fine finishing fairing compound which smooth out the grid 40 sanding strokes as well as the last imperfections.

The last part of this finishing process is sanding down the last fine layer of fairing compound with grid 120 and apply the high build primer before finishing with the two part high gloss paint.

About the color ….. Mint Green ….. It is a bold color and provoked divided reactions. However, somewhere in the nineties I came across a boat (the 40ft. monohull “Epoxydus”) that very much impressed me. It was mint green with a white deck. I loved it. Since that time I have that color in my mind and now I have the opportunity to make that true for my own boat. Only the crew needs some more time to appreciate it …… ๐Ÿ˜‰

I am very satisfied with the result ๐Ÿ™‚

Dangerous mood

September 14, 2016

After such a long construction period one must be careful not to make any shortcuts. It remains necessary to keep thinking about the things you do. So, what is wrong in this picture ?

dsc00070_450

This is the vacuum bag around the final laminate of one of the carbon beam anchors. Rule nr. 1 in vacuum bagging is to put no other parts in the bag except the epoxy laminate. And certainly not a rotatable shaft and bearings that needs to be dismantled again. What a stupid mistake. The epoxy has glued everything firmly together. D!#$* it was a hell of a job and only with brute force, an angle grinder and a hot gas flame the temporary shaft gave up his firmly connection with the carbon anchors.

The image below shows how it has to be done and this experience has put me back on earth again.

dsc00075_450

Anyhow, at the end I have 4 beam anchor assembly’s ready to put in the beams. And yes, that means I’ve finally started the build of the beams. More about that later.

Daggerboard construction

August 13, 2016

For a long time I thought I was going to make the daggerboard in the same way as the rudder. So, with the aid of a mold. To which I have just postponed that for some reason. But at the finish of the main hull the appropriate daggerbord case slot must have been created. A good reason at last to make that daggerboard.

I made it almost according to the plans, so with a Western Red Cedar wooden core. But to prevent this core against water penetration in case of a collision with an UFO, or hitting the ground, I made two changes to the plans. First a leading edge with a high density glass fiber core behind, instead of the wood, and second a bottom part with a foam core. In addition to these changes and for structural reason I replaced the wooden core in the leading edge by a glass fiber core.

Photo’s are better than explaining by words. You can find them here.

Enjoy the animated gif of the infusion of the daggerboard.

More fairings

August 2, 2016

More fairings, now on the starboard side.

Vacuum bagged first foam layer.

Building up the thickness with more (screwed down) foam layers. I decided to make a fairing on the front and bottom side of the escape hatch to minimize water pressure on the hatch.

This hatch recess was made for a Lewmar safety hatch, however, this type of hatch is not available anymore and instead I bought a Vetus Magnus hatch which is also suitable to mount in this location. However, size and hinges are slightly different from the Lewmarย  and so I had to make some modifications to the recess and hull.

While doing this, I also decided to cut away the aft part of the recess in line with the other fairings. (at the cost of a lot of itch on hands and arms ๐Ÿ˜ฆ

Structural integrity has been restored by adding some extra laminate.

All hull fairings are now finished.
