Tally Ho. Rigginginteresting vid today about

[Wansworth]

Standing rigging is going to be Dynamee,seems a win,win choice,who would have thought.TallyHo looks splendid in the drone shots

 

[ridgy]

Yes was surprised also. I thought Leo's claims of lack of quality of galvanised wire was a bit "I've decided I want dyneema and this is my excuse and I'm sticking to it".

Yes I agree ,ploughing steel galvanized wire was always available ,I bought from rigging firm who supply lifting business…….and what do tall ships use?

I was more concerned about one of Leo’s justifications for going to Dyneema. He said that they had “slightly raised the centre of gravity” of Tally Ho, so wanted to reduce weight aloft. I haven’t seen them do an incline, but guess this must be on the cards at some point If he truly believes that they have raised the CofG and affected GZ.

I thought that it was somewhat disingenuous for Ian to keep saying that dyneema doesn’t stretch. Everything stretches, just to a greater or lesser degree. I’ve also never heard that a rig can be set up with less static tension due to lower stretch (unless this is something to do with having a wooden mast, rather than aluminium or carbon), particularly when most synthetic rigging is sized to have equivalent stretch to the steel rigging it would be replacing. When I hear someone spout a couple of ‘facts’ that I don’t agree with it makes me wonder about the other things they say or know.

PS - agree with the statement that Tally Ho looks splendid in the drone shots. Almost too good to use.

Doesn't Dyneema suffer from UV degradation?

but it is wrapped as per TallyHo vid

 

[bignick]

I wonder how well their wrapping will stand up when their heatset dyneema exhibits any constructional elongation, or stretch as it is pre-tensioned….

I can't see it's a huge shock, the boat is chock full of modern technology, he has never hung his hat on rebuilding a copy of the original boat.
One key point, which I don't think was mentioned at all, is that the look of the thing will be in keeping with the boat. When push comes to shove it's just a different type of rope.

 

[bignick]

Personally I think it’s actually a very good choice. Deadeyes and lashings will look fantastic and be very much in keeping.
I was just objecting to the description of the properties of dyneema rigging.

 

[Wansworth]

Iwould rather it was galvanized wire…….nothing wrong with talurit ,lasted perfectly on my schooner

Not seen the video, do you have a link please?

 

[bignick]

Further to my comment about raising the CofG, I’ve just found episode #125, where they talk about it in detail.
Seems like they have tackled it pretty comprehensively, especially the weights estimate.

According to google 1x19 galvanized rigging wire available in the US

Am I alone in think that the proportion of weight in the rigging is relatively trivial in prportion to boat and sail weight, and if the CoG was that critical they have plenty of other things to worry about. An Aluminium mast instead of wood would have saved more weight aloft, and though it would not look as traditional (unless painted brown??) using dyneema isnt tradtional either

Too much weight in the hull /keel can cause a quick recovery from heeling whilst a bit of weight in the rig softens the roll……….but I imagine it all been thought of

 

[bignick]

I’d recommend watching episode 125. They discuss the weight changes in quite a lot of detail. Including that the mast is quite a lot lighter than the original, being made of aircraft grade spruce, instead of the original pine.

The owners who raced back in the day did several modifications, so would assume they would have used Dyneema if available then.

They mention using heat-set Dyneema. This page is worth a read; Colligo Marine - Tech Material — Colligo Marine as there are a few ways to reduce elongation in Dyneema. Firstly using a heat stretched fibre, second load setting any stays before fitting. On that webpage Colligo Marine do not say it will not elongation, but "maybe adjust the turnbuckle 2 or 3 times after sailing and then you are done!"

In the video I think they might have simplified that to address concerns around stretch.

Oh it’s been a wonderful project and I wonder how all those involved will move on especially Leo. May may be worthy of some award recognition. Tally Ho? Not so sure if it still is Tally Ho, more a reincarnation perhaps, but that is irrelevant now. I hope the wood has found some use.
