"Hello! As seen from the video this amount of loose rigging cant be due stretching of the ropes. Thing is, even when you do not use dyneema and when you lash many rounds and then few clove hitch knots over lashings, it should not give so much…"

Troubles with my rig

Bonjour, We went out with my Tiki 21 yesterday in winds from 15 to 20, some 25 gusts. Some chop. We finished with a reef in both main and jib shortly after my daughter took the video.I had the past week retentionned the shrouds and the forestay.But after half an hour or so, everything came loose again, and didn't get back the tension on mooring.Mast was moving in every direction, and leeward shroud was flying.I do not understand why. I used 6mm (0,236inch) pre-streshed dyneema, and made 60 cm…See More

"Eric, I have the same experience on my Mana, only I have run out of space on my stays for the main mast. I will have to cut and re-splice before starting this season. I do  hope that the stretching will end soon."

Tiki 21. Parts layout on the 15mm plywood sheet.


I started to loft yesterday, making templates for the 15mm sheet of the Tiki21.

I take careful mesurements, then tried to put everything on the 1200 x 2400 plywood sheet. Impossible. I cannot put everything. I finished with no space for one rudder.

Mesured again, and agin. Same results, can't find any mistake on my side.

So, question is: did some of you faced the same problem? I will if necessary find a piece of plywood for the remaining part, but I'd like to know… Continue

Before I order West System, ask help for clarification


I am now on the way to order the resin, and found West System in Shenzhen,China.

I am on for a Tiki 21, and, if some have experience in the building of this model

2-It is asked for : 406A 0.275 kg Colloidal Silica and 409B 4.5kg Microspheres (for fillets) OR

407B 3.5kg Low Density Filler (for fillets).

Is the reference 407B replaces bothe 406A… Continue

About the Wood Triangular Section


All wood has been sourced now, but the "Triangular Section". Not able (capable?) to find it standard, (here in China, Shenzhen area )and since it is not in the form of a "square triangle", (BC² = AC² + AB²) I hesitate on what to order to mill it myself with my hand circular saw mounted on a table.

I am on a project for a Tiki 21, and the base of the wanted triangular section is 32mm, while the sides are 25mm. Or, "Imperialy speaking" base 1 1/4" and sides 1". (I just…

Epoxy coating


Plywood is ordered and will arrive soon. Epoxy, I'm still testing. However, I have two questions.

-When you coat plywood with epoxy, is it acceptable to put the second coat before the first is totally cured, without sanding, or is it better to wait that the first coat is totally dry, sand and put the second coat?

-I tried an epoxy yesterday. The seller made the mixture on a scale. I took two pieces of wood, dry. I put some epoxy mixture on both pieces, tied them and made… Continue

Thanks a lot
J'ai commencé mon petit catamaran sans avoir d'expérience de la résine. Et j'ai eu quelques hésitations et la peur de rater. Mais au final aucun problème sérieux. Donc, vas y fonce.

Hey Eric thank you so much for the tip on window installation that was really helpful both systems are so sanitary it was a bit shaming comparing my technique to how they performed the job. I wish I'd been watching these two websites earlier I would've ended up with a much nicer building experience
