Hello people

I am just arriving to Wharram world. Starting building a TIki 21. After sepent a week readind the plans, I am cutting drawing and cutting the bulkheads, and hulls panels for the first hull;

I will need for help, a lot! There is the language barrier, I speek Portuguese, and the age,I am 67 years old.

I am following the plans exacthy as it wrote in the plan's sheets. 

In the design it is indicated to fasten the hull panel on the keel with wire loop.
You need to drill the panel. Is this usual? There is no other method less
laborious or invasive.

I am not completely sure what you mean.  Are you referring to holes drilled in the hull panels used to tie the hull panels and the bulkheads together?

If so, yes this is probably necessary. The holes will afterwards be cowered with the fillets, or you can fill them with thickened epoxy. There will also be a layer of glass fiber on top.

It seems strange to drill holes in the hull, but it’s really no problem.

Yes, I was referring to those holes. I was thinking about to change the wire stichs for stainless steel screws.

You could use screws, but the bulkheads are of relatively thin plywood, so it is difficult. And I would remove the screws when the bulkheads are glued in anyway.

I used cable ties instead of wire. Also perhaps not as many as in the plans. You just need to hold it in place until it is glued.

Rune is giving you good advice. The Tiki 21 is built using the "stitch and glue" method. The method was designed in order to make use of epoxy and its additives during boat construction. The epoxy provides the strength - it is stronger than the wood it is joining. The copper wire (or zip ties) are used to hold the wood in place while the epoxy sets. And then, as Rune has indicated, the wire is removed and the holes that were created are filled with epoxy and additive. I have built a Tiki 21 using copper wires, and recently I built a Mana 24 using zip ties. Both ways work fine - the zip ties are a bit faster and easier. Wishing you much success on your build.
