In this video I am stitching the side panels of the second hull together. At the end of the video I am taking a look at the drawings to see how to stitch the bulkheads. I then discover that I have glued the stiffeners on the wrong sides on 6 of the bulkheads. So now I will soon discover how easy or difficult it is to remove the epoxied stiffeners and deck supports.
Oops!
In this video I am glueing the stiffeners and deck supports again on the bulkheads, but now on the correct side. I discovered this mistake a couple of days ago. I think I don't have to remove the incorrect ones, just remove a little bit at places where these wrongly placed stiffeners and deck supports are in the way. I also started making a stand for one hull.
Good to see someone building a boat.
It’s something people have been doing for thousands of years and boats were built before carts or any wheeled vehicles I’d imagine.
I built my first boat in 1976 (International A class catamaran) whilst in my last year of school, and really enjoyed feeling it float for the first time at a stage in life when there was not much happiness to be had.
Keep the videos coming please, great work!
An excellent deduction Watson. You do realise that the hull with the extra stiffeners will be heavier and extra ballast will need to be added in the other hull.
It may also be deemed non-standard and you will be disqualified after you win the Olympic Gold medal
In this video I first clean up the workshop. Then I do some work on placing the stiffeners and deck supports on 2 bulkheads (again). I also assemble one of the stands for the hull. I use epoxy and some nails to keep it all together while the epoxy dries. Later I will add fillets to the stand to make it all stronger.
Will you save much weight ?
Stiffness and support are good things.
I don't think anymore the weight of the extra stiffeners and deck supports is an issue. But in it is very good practice with Wharram builds to stick to the plans. At the moment I have not removed them yet (I tried a bit with a plane and a chisel, but I think I wait for a multitool that I ordered).
In this video I am glueing stiffeners and deck supports on the bulkheads and I am adding fillets for more strength on the stands.
Keep on glueing Marcel .....
You'll be launching soon.

In this video I am stitching bulkhead 3 and 2 in place in one of the hulls.
Coming together well. Keep up the good work and videos.
In this video I stitch bulkhead 1 and 4 in place. Afterwards I am spatulas with 2,5cm radius out of thin plywood, which I will use for making the keel and bulkhead fillets.
Four questions.
1. The bulkheads have typically a horizontal stiffener, at the top (hull sides level). Also one side, usually the shorter side, of the two top bulkhead edges. Why not the other top edge as well?
2.The copper wires are holding the hull quite loosely. When will you be firming up on the dimensions, twisting, diagonals, lines etc. Or are you relying on the fit of all the component parts.
3. I am assuming you will be fibre-glassing the hulls.
4. Have you thought of adding an adjustable "J foil" out of the hull bottoms to lift the hulls out of the water?

A tray full of GOLD is not worth a moment in time.
Hydrofoils on a Wharram ???
Better to have aluminium or stainless steel rubbing strips on the hull bottoms and bows and sterns so you can drag them up the beach without wearing through the glass and ply.
Hello OhOh,
I am just back from the workshop.
Answers:
1. I don't know (yet)
2. Today I clamped the two sides at the stern post together, which was not stitched yet. After clamping it, I tightened up all the stitches. I am relying mostly on the fit of all the components parts, eyesight, intuition
3. yes I will be fibre-glassing the hulls
4. I am building this Hitia 14 according to the building plans
Thank you for your interesting questions.
I am going to make the video of today's work now.

In this video I start with making the fillets for the keel. First I stitch and clamp the side panels to the sternpost which were still not together. I had to use clamps, because the copper wire that I am using is too thin to keep this part together. Next time I will use thicker copper wire. After that I tighten all the stitches. Then I lightly send the areas where the fillets will be and after sanding I use the vacuum cleaner to take the dust away. Then I start to do the filleting. The straight horizontal part goes very well. The stempost part that is at an angle does not go that well, there are several bumps in the fillet. I will try to sand that smooth tomorrow. It was a good day.
What's your music choice?
Did I see you use a plastic bag to place the fillet mix. Do your plans indicate the fillet spreader dimensions?
Sometimes like in this video you will see me wearing earpods. I listen to 4 different things:
1. thai language lessons
2. Alan Watts talks
3. Sadhguru talks
4. music from the 60s
The fillet mix I prepare in a paper cup. After getting the right consistency for fillets I put the mix in a plastic bag and I cut one corner of this plastic bag, then I can squeeze it out with a bit of pressure. Works very well, less messy.
The building plans indicate spreader / fillet dimensions, which for the keel and bulkhead fillets is 1 inch / 2.54 centimer radius.
