7X7 for standing rigging?

I'd like to redo all of my standing rigging. The plans say to use 6X7, but this seems unavailable in the US. I have found 3/16 7X7 in 316 stainless for a good price.Does anyone know if 7X7 is a…Continue

"Thanks Everybody, The key insight seems to be that the beams are lashed on alternate sides so that there is a lever arm on each hull to stop it rolling over. Am doing it in a few weeks and will post pictures. Roger"

Extending or reducing beam on the water

Has anyone tried disassembling their Wharram on the water by moving the hulls closer together for trailering or vice versa? I have seen pictures of people launching with the hulls close together using a set of short beams, and then extending them on the water. I can't figure out how it would actually be done. Please let me know if anyone knows the secret.RogerSee More

"HI Michael, Your new build looks amazing and the photos show that you did a really nice job putting her together. I am Roger with a Tiki 21 called "Little Cat" in San Francisco. How does she sail with the beach cat rig?"

Roger replied to Éric Bouvéron's discussion Tiki 21. How big is your asymmetric spinaker
"PS I see that your message was about assymetric spinnakers. My 230 sq foot doyle is an APS which has a very flat cut. The flat cut allows it too sail closer to the wind (a bit higher than a reach), but it is not good for sailing deep angles. When…"

Roger replied to Éric Bouvéron's discussion Tiki 21. How big is your asymmetric spinaker

Hi Roger ! 

I sure that there will be no need to shorten the rudder arms. The Vane get a small outrigger ( 15mm ply  ) which will be mounted at the back of the cabin. So the wind vane will be higher the cabin and outside the Hull. It will be a flexible construction, just mounted in need. ( straight course  longer than 45 minutes ) When I go over the Hull I will also change the the vane to opposite. When the arms get in collision  with the braked and the butterfly nut, I need to shorten them for a few mm. 

Thats the plan right now, one of many " up to now plans "

First I decided to build a additional beam on the back, and remote the van with two canvas. Now I will fix my Back Nettings in the same eyestrap which I made for the  mainsheet traveler.

I´ll will give you report, pics and vids.

 

Jorg

Hi Roger,

I think as long as it is as far back from the main as poss it should work OK. Maybe rig up some sort of small vane, go sailing and see what sort of interference there is.

Cheers Rory.

Hi Roger,

That was my first message to you. I haven't sailed my Tiki 21 for 5 years. I am working on getting her back in the water and a deck tent and new trailer are on my list. I live in Manitoba, Canada and we are still in full on winter here so I have some time before sailing season. I spotted your two ads on this site so I thought I would just check and see if they were available. How much are you asking for the two items? 

From your page it looks like you have done some serious sailing in your Tiki. I have sailed on my brothers Ranger 23 from the Queen Charlotte Islands to Vancouver Island, but that is the limit of my ocean sailing.

Looking forward to your response.

Rick

I have on my Tiki 32.5  a roller furler for the jib plus about the same setup for a big flyer and It works pritty well in light winds.

Hi Roger,

thank you very much for your response!

I did not build my Tiki by myself and I have not very much experience, so therefore my questions might be a bit amateurish ... 

How did you manage to make the piano hinge waterproof? Or did you glue it with epoxy only?

Thanks, Reinhard

At 3:37pm on August 27, 2014, Reinhard Käferböck said…

Ok,

looking forward to your photos!

By the way - your blog is very informative!

Reinhard

Reinhard, from your photo it looks like your hatches are two part, like the standard design, except they are not connected together by a hinge arrangement?

Hey Roger, Michael from Seattle here. I just wanted to say thanks for the awesome blog - it's amazingly helpful as I re-rig my T21. I've been puzzling over the jib sheeting angles, and your post covered it nicely. Then I was wondering "how do I make those cool soft pad eyes?", and found that post too. Thanks for all the sharing, it's much appreciated!

hi Roger. This will be my second summer in my Tiki 21, up here in the Vancouver, BC area. I've added a bowsprit for my small spinnaker a used gen that I got, but my question for you is about your mainsheet setup on Little Cat (love your blog and the way you've maintained and tweaked your Tiki) Last year I tried the rope traveller between the two sterns, but it didn't 'travel' very well. I see the pictures on your site, but can you tell me a bit more about it? Is there a rope that the mainsheet pulley moves along, or is it just attached to the ropes that pull it towards each hull? Also, why is the rope wrapped around the tillers?  Appreciate your time. Steve

That's clear; thanks so much.
