"If the jib tack point is far enough forward, you might consider dropping the connecting beam onto the decks, in line with a projected forestay. Then it would help to drop the bridle leg attachment points further down the stems. This would improve…"

"So my bridle legs are made from good quality 10mm spectra,4.5 tonne break,terminated in the centre by one loop and two bow lines to a shackle and two loops around the seem posts. Strong enough you think?"

"Dave is right about the bridle loads.you have a trade off necessary here.the bridle load increases as the bridle legs get shorter. the jib gets smaller as the bridle legs get longer."

"I do not see anything wrong. At this point, I think you may have been overly dramatic. "Horizontal" implies that the bridle/forestay is near parallel to the deck, which is definitely not the case here. Maybe you were mistaking the dock…"

"Hey Matt, I like your idea of using the rig which Hans Klaar developed on Ontong Java nd was copied by the other Hans on Wakataitea. In fact this same rig is what I intend to use on my 30 ft Polynesian Pahi if it turns out that I find shunting to be…"

"I don't see a problem with the headstay/jibstay angle. Sure, doubling up the stays and having one to each bow is an option as well as an additional jib luffstay. Tension in a bridle is taken in compression  by the beam closest to the…"

"Now I am confused. If you mast is between 1&2, and rakes back at 10 degrees, then your forestay should not be anything close to horizontal. It should be sloping a little more than a sloop and create a low aspect foresail area."

matt connolly replied to matt connolly's discussion Forestay bridle angle
"I was thinking to have a small head sail,also as an option in strong wind. My mast sirs between cross beam 1&2 and rakes back 10 degrees. It could be done?"

Budget Boater replied to matt connolly's discussion Forestay bridle angle
"Twin headstays is more simple than a bridle, offers some redundancy, and gives triangular support. If your mast is so far forward and raked such that your forestay is near vertical, then you cannot fly a jib anyway."

matt connolly replied to matt connolly's discussion Forestay bridle angle
"Thanks guys,l was wondering about that option BB,why would you do that? Would you still have a head sail? "

I have a tangaroa mk iv that has had its beams replaced with aluminium beams and tiki style lashings works brilliantly   the beam o'all has been increased to 6m  .. I have no idea on the cost  but could perhaps put you onto the previous owner who did the conversion

Matt I fail to understand Wharram's comment that Crab Claw is only for very experienced sailors. But this is not the first statement from W. that I failed to understand. Perhaps it is just me.

I don't know why any of the "crabbers" did not pick up your post. Frankly I waited for a vigorous discussion. Doubtless once I post a suggestion this will change and we will have a flood of replies showing how I got it wrong !!

I will put some thing together but I need an idle hour as I will need to post a drawing etc. I will try to do it soon.

Matt I am more and more pissed off with this site. Almost no body is sailing it seems. You get huge amounts of replies to useless things like "best way to fit a fiddle rail". At the same time simple questions like "what is the head room in a T21" drag on for weeks without any actual measurement. A prominent contributor posted photos of a finished boat last year. Still in no hurry to actually put it in the water. I better stop here.

You sound like some one who actually wants to go sailing. Keep in touch.
