Three hulls coming together.

February 14, 2018

Three hulls coming together in three exciting moments.

The first one, aligning the lower folding struts with each other and in square relation to the mainhull. The distance difference between the for and aft lower folding strut at the inner end and the outer end is 6mm. on Starboard and 2mm. on Port. This means that the alignement of the carbon folding anchors in the mainhull is quite good. A great achievement and kind of reassuring for the next steps.


The second one, first trial of the folding system. It works great !


The third one, the final assembly of my trimaran. The transformation of three hulls and four beams into a boat is the climax of the construction. Finally everything comes together and leads to the trimaran I dreamed of. It is definitely a highlight of the construction so far. Although seeing her full beam for the first time is a bit intimidating …

Floats down to Earth.

October 21, 2017


It’s been a long time since we hung the first float under the roof, followed by the second one. All those years they have collected only dust but now they can come down again.


Something has changed.


The port float is hanging above and behind the boat. To bring down the port float I first had to make room next to the boat. The boat has to slide sideways to create ample maneuver space for the forklift. With the help of two pallet jacks the boat easily slides sideways.


With a makeshift boat-stand clamped to the forklift I carefully lifted the float, unscrewed the tensioning straps the floats were hanging in and bring it down. However, maneuvering with forklift and boat only takes one way. The port float is still looking in the wrong direction but turning is not possible because of lacking space. The workshop crane brings the solution.


In the free space somewhere in the middle of the workshop height, I can turn the boat in the right direction and bring it back to the position at the port side of the center hull.


The other float is much easier to reach and is already hanging in the right direction. There is still not enough maneuvering space for the forklift but taking it over by the workshop crane brings the float to its position at the starboard side of the center hull.


After all the dust has been removed, the first work is putting the floats upside down for applying the Coppercoat anti-foul.

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 LewmarĀ  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 šŸ˜¦


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.

High time for an update !

June 19, 2016

My last post was from December 2015. I am ashamed.

It seems as if nothing has happened, but on the contrary, I have been very busy and have made good progress. But to be honest I have not had a lot of inspiration for updating my blog and website. Perhaps also because of the fact that lately I share my build adventures also on a Dutch sailors forum, which is again time consuming but at the same time much easier writing for me than in the English language. Google translate is still my best friend šŸ˜‰

There has always been a demand for a Dutch version of my blog and website but I could not find an easy way to do this. So I found this alternative solution by sharing my building adventures on this Dutch sailors forum. My contributions regarding the building of FramĀ can be found with this link.

A recently sad event is that my dear mother passed away. Next month she would have been 98 years old, a respectable age for a respectable lady. We have organized an impressive funeral for her where she would have been proud of. We have cleared her cozy apartment and distributed her personal belongings and preserved for posterity as good as possible.

Sometimes some things are more important than building a boat.

You would have not expect it by the limited updating of my blog, but 2015 was a record breaking year regarding the hours (850) I’ve spent on building my boat.

Normally at Sundayā€™s Iā€™m working on the boat. But not today, today is Fatherā€™s day. I have had a nice family afternoon and for the rest of the day I finally found some time to provide an update for my website.

The following photo galleries has been reorganized and provided with new photoā€™s:

Aft cabin and cockpit construction

Finishing the stern

Transmission steering system

Waterballast tank

And I have added a new chapter called ā€œAft cabin interiorā€.

Below deck drainage of hatches

January 25, 2016

With the hull now upside down it is much easier to make the below deck drainage of the deck hatches.

Click for photo gallery

At first I had the idea of molded gutters and I did made them. In hindsight this was a bad idea, they do not fit very well and an acceptable finishing will be time consuming.

A PVC hose does a better job and is laminated against the underside of the deck and connected to a short piece of fibreglass tube through hull and through the molded hatch recess.


For the underdeck drainage of the foredeck hatch I choose for two straight fibreglass tubes.


Also under the bridge deck in the aft cabin one straight fibreglass tube is reponsible for the drainage of water coming from the cockpit seats as well from the aft cabin hatch.

Upside down again.

December 15, 2015

So, another milestone, the constructive work on the outside have been declaredĀ ready. The work on the outside of the mainhull, except for a few small details, is doneĀ and the hull is ready to beĀ primed and painted. However there are still a few more constructive things to do inside, especially under the aft cabin bridgedeckĀ where a further strengthening with UD glass is necessary to absorb the compression loads from the rear beams.

In order for it to let gravity no killjoy, I have thereforeĀ turned over the hull once more. Also at the inside of the cabin roof are some chores to do, such as the installation ofĀ drainage channels for the flush deck hatches. This upside down position comes also in handy for a part of the putty and paint work on the outsideĀ  (and maybe inside cabin roof).

I have thought it out very well on how I’m going to manage this on my own (and safe). Lifting and twisting such a big hull is always a little exciting but I donā€™t want anyone else around, that would only distract. It took me the whole Saturday but it was worth it šŸ™‚

Getting here in late afternoon was tiresome, but then it went fast.

A little trick to get the hull to the other side.

Almost there, piece of cake ….

…. and done
