AIT Around In Ten

The rig would be stronger and have less weight I believe.

This weight issue counts extra for the boat's stability since it's aloft weight.

Heavier on top will give a higher center of gravity and consequently a lesser stability.

 

ok im still not decided on whether cable shrouds or solid frame area stronger. i guess shrouds would offer a little flex which is better than a snap?! also shrouds are lighter.

anyway i think this concept may be a contender for my design:

(of less relevance, i have included an aft cage in place of an aft sprit as this will raise the stem head increasing sail area and give a safe exit from aft hatch in storms).

 

-

If used, the bowsprit and the aft sprit should also have side stays, attached as wide as possible to both sides of the hull.

The bobstay (aka water stay) is best attached as low as possible to the hull, the same goes for the the aft sprit.

The quoted sketch comes from: Bowsprit Rigging

P.S.

In Dutch an "aft sprit" is called a "papegaaistok" which literally means "parrot stick", the right English word for it doesn't pop up in my mind right now, please help me here

 

I did use the term aft sprit as it seems appropriate, I'm self taught so there are gaps in my knowledge, I think we understand each other though!

Because there will be always some movement in the cage rig the frame of it will soon suffer from metal fatigue and break.

And the cage material will be thicker as steel cable or dyneema I think, so there will be also a windage issue, which like the weight issue will count extra since it's aloft.

So with a cage rig the boat will have even less windward ability than with fore and aft stays supporting an A-frame mast.

 

For the aft cage I'll think there will be metal fatigue and weight issues like the cage rig has.

But because the aft cage will be lighter and lower placed the weight issues will be a bit less, except that you also don't want that extra weight on your tail.

For good behavior the boat's weight needs to be centered as much as possible, and as low as possible for stability reasons, and also for balance the extra cage weight aft needs to be compensated by extra weight fore.

You could replace the aft cage by an aft sprit and use side stays and a water stay like in post #408, when doing so the aft sprit could stick up like your aft cage, but the max hight of this stayed and upwardly projecting aft sprit will be limited by the minimum angle the aft water stay needs.

The bowsprit could stick up the same way as the aft sprit, if you need that space for the sails.

Good luck !

 

I like the idea of having a swimming platform or aft cage for safety and comfort, so I figure it makes sense to combine that with the aft sprit which will decrease the weight issue. The weight increase doesn't worry me too much as most boats have pulpits and rails anyway. I am with you though that windage and center of gravity both need to be kept as low as possible. A low center of gravity is the most important factor in my mind, windage is easier to compensate. It would be nice to raise the stem head and increase sail area, so an ideal compromise will need to be sought.

OK, maybe best now is to follow Sharpii2's advice in post #402.

Since there's a contender now ^#407 for the Cage Rig you may want to draw different scaled sketches of the boat + the possible rig types to compare the options, or for starters just the boat + the rig you fancy most right now. This is to see if your current ideas for the boat and the rig are matchable in scaled sketches.

Good luck !

where has manie gone with his around in ten boat??

I have not seen any posts here for some time now. I have been following Sven's progress but am missing Manie.

 

Hi Rayman,

Don't know about the use of Manie's TEN^{(thread link)}, but Manie himself seems to have had a career switch to a Cape wine farms tour operator at WineOkes . . .

​

↑ WineOkes Introduction published on Dec. 19, 2016​

Maybe you can give him a call, since SA Hidden Gems | All things wine has Manie's SA phone number in the left top corner, don't know if that's up to date though.

Wish you all the best Manie, please give us an update about yourself and your TEN . . .

 

That is his mobile phone number which is saved on my phone for ages. I spoke to him about a year or so ago on his number and also contacted him in the past 12 years or so on that number, so its safe to assume it is still active...

When I last spoke to him he was ecstatic about this wine route thing and sounded like he enjoyed it tremendously, must be true since the sold up and relocated to Cape Town. It must be lucrative business with all the foreign visitors with wallets filled with euros and dollars whom cannot get enough of the the picturesque Cape and the many wine-lands abound in the surrounding valleys and the world class products they produce.

My son relocated to the northern suburbs of Cape Town recently and I actually feel bad not looking up old Manie when I visited a fortnight ago. However, I plan to go visit my grand children often and will look up Manie next time and catch up on old times over a Castle or two

 

Thanks Angel and Wynand, I am afraid I won't be calling anyone, my poor little phone costs $1 per minute so I do all talking with my fingers either on txt or here on the library comp. Sad about EXLEX but at least he left home (again) I hope Manie doesn't leave his venture until he is too old. There was an elderly french man rescued here (aus) off Cape York about 18months ago in a little walnut of a boat, I forget where he left from, poss. somewhere in French Polynesia I think, but the sharp square seas in the Torres Straits was more than he could handle, he was rescued sea sick and battered half to death. give Manie my best regards, and please update us thru here whatever.
regards rayman in the sunny great sandy straits.

 

Yeah time flies, that happened in 2013, Daniel Alary 70 y/o at the time, rescue due to suffering from heart problems it says, indeed departed from French Polynesia, 9' (2.74 m) boat named Poisson d'Avril (April Fool) . . . .

* the headline says 8', but the article says ‘‘2.9 m’’ which is 9½', IIRC the bare hull length was ± 9' (2.74 m), like it says in the below Torres News article...
