Rory McDougall replied to Roger's discussion 7X7 for standing rigging?
"Hi Roger 7x7 will be fine. Tiny bit more stretch than 1x19 but for Wharrams that makes no difference. My advice would be to renew your bridle u-bolts at the bows especially if they are the 6mm to plans. I have 10mm on Cookie - only cos that's…"

TIKI 21 CATAMARAN COOKIE NEAR THE FINISH OF JESTER CHALLENGE 2010

"Hi Thierry, Yes the mast definitely pumps when going to windward. So it is important to build a strong mast base for the Tikis. You will always get some movement on a beamed cat. You can keep tightening the rig but you will just bend the boat -…"

TIKI 21 CATAMARAN COOKIE NEAR THE FINISH OF JESTER CHALLENGE 2010

"Hi Rory, it is impressive to see the mast moving so much compared to the lee hull. Have you ever thought it should move less? Or is it because of the camera moving? Are your lee shrouds quite slack when beating? Do you think lashings on both sides…"

Shroud guard detail

Hi Rory,

Just sent you a comment, then saw yours to me.  Tiki is at Turf.  She's still up for sale but I'm not disappointed not to have sold her.  Should be on the mooring at the begining of April.  Love to take you for a ride - I'm still in the process of simplifying the rig and everything else - trying to talk myself out of crab claws and junk rigs.

My friend Nick in Exmouth with a Tiki 21 would love to pick your brains about mast rake etc (he has a GRP hull like yours I think)

Hows the new job coming along? Did you spot that there is a dinghy sailing school for sale in Exmouth?  Might not be your thing but worth a lokk - Sail Exmouth I think it's called.

See you at the Lympstone SC for the talk hopefully.

Paul

Hi,

Definitely keen to talk to people who might want a Tiki 31.

The wind sils are great, but I find the more I read, the more I want to try things out - for comparisons sake.  I'm playing with balance - modern boats have the centre of effort too far aft, which leads to extremely weather helm. The most balanced boats I've sailed (Rival 34, Contessa 32) have the coe much further forward.  They don't get headed off, the helm effort is lowa nd you get a much tidier stern.

Weather is nice isn't it? I am moving a boat from Plymouth to Falmouth this weekend in anticipation of a couple of weeks of teaching.  Hoping the thermals and waterproofs are up to it.

I think we might have ehough Wharrams in the Exe to organise a rendevous, I think there are 6 that I know of.

Been out sailing much lately?? Love seeing all the smart new mod-cons you add to Vaea. can I ask the meaning of her name??

 

Rory,

 

After having real wind pressure reset the 12-strand braid dyneema on the forestay, it was too long!  Fixed that by making another forestay out of dynex dux (kind of a "heat-treated" dyneema) that I made shorter: I was worried it would be too short!  I went up the mast recently and exchanged the stays and it turned out just right. . .When you get the dux it feels as stiff as wire, so I was careful to only disturb the set of the braid to make the brummel spices at the ends, thus keeping the amount of re-set to a minimum.  The standing rigging is nice and tight now, so Vaea's new sails should take the breeze even better. Vaea is polynesian for Peace.

 

I need to get some sort of video camera to record Vaea's seatime! That is quite the sea state you and Cookie are making way into!!

Dear Rory

I'm planning a Windvane steering for my Tiki 33 (WaveDancer) and I'm very interested hearing more about your "Harry". How it worked under different conditions, improovements,

suggestions, buildingplans etc. Thanks in advance and all the best for your future ventures. WaveDancer

Hi Rory!

 

Thank you for your excellent informations. We are indeed studying the possibilities to mount a Pacific light pendulum Vane or as an alternative a trimm-tab. But since a Windvane mounted on the aftbeam could be very vulnerable to impacts of breaking waves I'd actually prefere to mount the windvane also on top of the cabins. If we find a solution I'll bublish it in the forum. Meanwhile all the best and regards Wave

Hi Rory,

 

First of all i like to congradulet u from your sailing trip Jest Challenge.

I built a tiki 30 five years ago with a wooden mast. The problem is that the mast is rotted, and now i'm interested in finding an aluminium tube (6082 t6, 9,5mts length, diameter 140mm, and thickness 3,5 to 4,5mm) to adapt to a mast.

One of the problems is that i can't find any supplier in Portugal for aluminum tube.

Do you know any EU supplier (cheap) that i can ask a budget?

 

Thank you for all the help.

Best reguards

Rory,

If you don't mind me asking, how are beams on Cookie lashed? The inner lashing looks conventional but I can't see the outer one. I'm wanting to build with a raised deck but don't want to fully box the beams as far as the outer lashing...

Info appreciated..

Cheers

Al

Hi Rory,

Thanks for the detailed information, I will be building a 1/10 Balsa in the next couple of weeks to get the decklines and an approximation of the bulkhead measurements (I'll be posting pics for everybody's amusement). I'm researching a more rectangular beam form as opposed to the standard triangular Tiki 26 beams so I can keep them flush on the deck.

 

Cheers

Al
