Great video. Thanks. We have just had the standing rig renewed on our Belize. I now feel much better equipped to check it once we have done some miles.
Thank you for walking us through. You hear these words used but never get a practical explanation. Great video.
Cheers mate. Hope you and the family are well
Great video Shayne. Love your content and how your whole family is involved with the boat projects. Your kids will be absolute Pros 🙏👍
Thanks mate
Great video Shayne. I always learn something from the master!
Cheers Ford. Hope all is well. Looks like you guys are having a blast
On the martingale tensioning, to make adjusting easier rather than letting off the shrouds, bring a halyard down to each bow and grind them up tight before making adjustments. Much easier.
Timely for me because I step my mast next Thursday and I am out in the boonies so another brilliant and timely video. 🙏
Nicely done. Never heard about the need for prebend in the cross beam.
Amazing tips!!! once again thanks a lot youngbarnacles crew!
You're welcome
The guys at Nance & Underwood in Florida could stand to watch this. After their 3rd failed attempt and bending my boat, I wouldn't let them back on board.
Ouch! Sorry to hear that. There are A LOT of cowboys out there.
@youngbarnacles the worst part is they're supposed to be the best. N&U are the riggers that the biggest catamaran service center in South Florida uses. If they're the best I can't imagine how bad it could get.
That doesn't surprise me. We've been called in to fix a lot of stuff done by so called professionals 😅 Even at the top end of the scale there are issues. The marine industry is still the wild west and there needs to be more regulation / education around best practice methods.
Great video😊
Thanks 🙏
Very interesting as usual!
Thanks
Thanks for the info but I am a bit confused with the prebend? Isn’t 1% of 15m 15cm ? So is 30mm correct ?
1 percent is 150mm and 2 percent is 300mm for a 15m mast
@@youngbarnacles I think you said 15-30mm in the video at first (which is why I am here checking the comments straight up. I was interested because I got told by my designer to put between 1 and 1.5 mast cross sections lengths in - which I guess is about the same.
Yeah that's a good rule of thumb to use. Apologies, I fumbled a bit with explaining the math
Thanks for doing this detail, very few videos go to this length , yet it is so important to have the rig "right". I would be interested to know the rake on Pikea,s mast in t he video it looks well aft ? As the owner of a non standard cat without rig specs I am keen to learn what is optimum rake ? Rig tuning and SU tuning are my favourite sports !
Paikea's rake was definitely too far aft to start with as we reused the forestay from the old mast which was slightly too long. We ended up shortening the forestay in Saint Martin. There is a great rigging shop there which we would recommend. We have a video talking about mast rake here - ruclips.net/video/jaCivOaCi4Q/видео.htmlsi=gsv5WMIYGLk5YtdH
There is no magic formula for optimum rake on a boat. Basically the rake in the mast moves the centre of effort around so it relies on a lot of contributing factors. For example, it is influenced by the size and shape of sails you are using. It also depends on your rig shape and stiffness. It also depends on where the rig is located on the vessel. Lots of factors to consider.

Shayne you mentioned a locking headboard for the mainsail that locks open, which manufacturer was that? Does the video on your site show what you use to secure turnbuckles?
Do you mean the "pull to engage" locking system that we have on Paikea? There isn't anything good for smaller yachts/cats out there. Shayne custom made ours. Rigging Projects make them for much bigger boats but do not make anything smaller for cruising vessels. Antal has tried to do something but it isn't very successful and we wouldn't recommend it. Same with Harkens attempt.
In terms of securing turnbuckles we use M4 cap head bolt(screws) with ny-lock nuts. These go in the thread ends of the turnbuckles instead of split rings.
We cover them in this video here ruclips.net/video/mNXejSmeEE8/видео.htmlsi=SVuimy9Q5KVAx47J
@@youngbarnacles So there's not an off the shelf item, but only custom solutions. The one word I didn't search for turnbuckle in your video list. Thank you for the information and link.
Correct. No good solution for smaller cruising yachts unless you go custom.
