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 …… 😉

I am very satisfied with the result 🙂

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 Lewmar  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 😦

Structural integrity has been restored by adding some extra laminate.

All hull fairings are now finished.


Beam strut fairings

July 5, 2016

Before starting the filling and fairing of the outside of the hull a streamlined foam patch must be added to the front of the beam struts.

The first foam layer has been glued to the hull with the pressing help of a vacuum bag.

Then the next layers are easily being screwed down.

The final fairing still without a layer of glass laminate.

And of course the same fairing but a little smaller for the aft beam strut.

After adding the laminate around these fairings the filling and fairing proces on the outside of the hull has begun.


Underside deck fairing.

July 4, 2016

I would like to move on with the filling and fairing of the hull on the outside, but, while the hull is still upside down, now is the time for filling the inside of the deck, cockpit seats, cabin and aft cabin roof. It is much easier to carry out this hard work on my knees than later on above my head.


Second float is finished.

July 16, 2006

Fairing and painting the second float. Open this album to see the finishing of the second float. Both floats are ready now and waiting for the assembling with beams and main hull.

Floats are ready


Final painting and relocation of the first float hull

May 18, 2005

Finally the time is ready to move the hull to another storage. After the final painting the hull is stored in another place, waiting for the assembly with her starboard twin sister.
