  1. Hey All, I recently purchased a Newick Summer Salt 26 trimaran. It doesn't fold but it does come apart with the akas (beams) plugging into sockets in both the main hull and the amas (outrigger hulls). The forward akas have their ends in rough shape at the end walls. The main hull sockets seem to have been filled but this created a half wall at the end and a spider web of gaps. What do you guys think of this structurally? How would you approach any fixes? Cheers, Michal

    Newick Outrigger 26/Somersault 26

    Ahh, much better =) cool project! How tall is the mast? Your sails sit pretty high off the deck. I'm thinking it would be useful to get the clew of my jib higher off the deck to better control twist going upwind. The slope of the deck is pretty radical. Right now I can either (1) move the car up to reduce twist but run the clew into the car too soon or (2) move the car back and spill out the top.

    Fixing image rotation

    To fix image rotation use https://www.onlineimagetool.com/en/rotate-png-jpg-webp-gif and select "auto" for rotation then upload the saved image. Images can have additional information stored in what's called the "exif metadata". The exif metadata can store rotation (eg. 0°, 90°, etc) in addition to the unrotated image pixel data. Sailing anarchy forums don't apply the exif metadata rotation (a bug in the software if that's the case). Another useful thing would be for them to automatically resize images down to a smaller size. The attached image was take with a Google Pixel 3 with EXIF orientation set and displays correctly on most modern image viewers.

    Fixing image rotation

    That's because the forums already fucked you and stripped the exif metadata without rotating the image data.

    @carlwasher I had a chance to measure some of the rigging yesterday. The forestay is 3/16" stainless. The side stays are 3/8" dyneema.

    The broken image rotation has nothing to do with Apple products or Apple users. I suggest we move the image rotation discussion to the FAQ forum (linked below) where you will also see an explanation of the issue and an example from a Google android phone.

    @drivejunk images have additional information stored in what's called the "exif metadata". The exif metadata can store rotation (eg. 0°, 90°, etc) in addition to the unrotated image pixel data. Maybe sailing anarchy forums don't apply the exif metadata rotation (a bug in the software if that's the case). I just ran into the same problem elsewhere and found that you can fix the image before uploading using https://www.onlineimagetool.com/en/rotate-png-jpg-webp-gif just select "auto" for rotation.

    Dave has done a bunch of good work restoring his boat already which i think will be useful to take into account when improving our boats.

    Newick Outrigger 26/Somersault 26

    Thanks for the reminder Pat. @carlwasher - just saw this thread. Great to see more boats getting together with so many close to lake Ontario. Let's do a meet up when covid is come and gone? My mast section is 4 3/32" x 6 1/2" with a wall thickness of 0.125". I need to check height. This is bigger than Dave's section from memory. I have more info at home that I can send out in the next couple of days. I see you already have your mast up but I can also document the process for katchka (x-sparky) when I get it in the water in the next week or two.

    Newick Summer Salt 26: akas & sockets

    All this talk reminded me of a time I went out sailing with my sister, her friend and my toddler son on the summer salt last year. As fathers do I forgot the milk bottle at home and grabbed a plastic wine glass from the TMCC club house. My sister knows the basics of sailing but she was never on a multihull or a sailboat larger than 14 ft. She steered under motor while I fed and got my son to sleep in the forward bunk. We got some sails up and quickly reefed down as we started feeling the gusts come in. The sea state got rough once we got out in the open water and my sister's friend didn't seem to be enjoying himself. It was only after 20 minutes bashing upwind into the waves that they let me know that he didn't know how to swim and I got him off the upwind tramp and into the well protected cockpit. To my surprise my son had slept through all of this for a solid hour and a half. When he woke up and I went down below I was amazed to find the wine glass still standing on the port bunk where I had forgotten it in the commotion at the start. I remember being mesmerized and staring in disbelief at the milk barely swaying in the glass with not a drop spilled despite what was going on outside.

    Also paranada - do you have any photos of the rudder linkage mechanism under the rear hatch?

    Newick Summer Salt 26: akas & sockets

    Thanks djh. The beams were indeed a bit of work to get out at the end of last season but not that hard in the end. Previous owners recast the sockets and that made it better. Nice rudder paranada! Was it a DIY build? Here's a video of some hobby horsing under motor (excuse the low audio quality). Maybe it's exaggerated by the small low windage bow? Here's another video of some nice sailing last year to get us through to better times. Again, excuse the poor video quality but for me seeing water stream off the amas never gets old. It was actually a video of the echo II design "mocking bird" sailing that got me onto Newick's designs. Slow progress on the rebuild but only the boom needs fixing at this point. Does anyone have experience with brazing aluminum with products like this? https://www.amazon.ca/Bazona-2019-Alumifix-Flux-Cored-20pcs/dp/B07TBV33BP. The idea would be to close up the existing tears and drill new holes for the screws elsewhere. You can see the cap through the torn out hole in the image attached. Cheers

    Newick Summer Salt 26: akas & sockets

    Hey @dclayman, great to hear from another summer salt owner! I've sent you an email. It would be great to see the work that you have done. I'm based out for a Toronto, Canada. We've spent last summer on lake Ontario and mostly near Toronto except for our trip out to Prince Edward county. We may try to trailer the boat somewhere else this summer for an extended cruise but we'll have to see how it goes with our youngest son (born last week). I attached a picture of the mast tiller mold I'm making. The idea is to close it off on top with flat fiberglass panel so it becomes a tapered box section to better resist twisting loads (the tiller control line is angled down).

    Sealions hijack sailboat

  16. Hey All, I'm taking a recent dismasting as an opportunity to lead my halyards in-mast. I'm curious how others have rigged this up on a rotating mast. Please share your setups! I suspect the original setup on my boat only used the external block. In the pic you can see that using both the sheave and the block doesn't work (the block gets jammed against the mast). It looks like I need something below the sheave to allow the halyard to rotate as the mast rotates while keeping it in alignment with the sheave. Possible solutions: 1) fairlead (high-friction?) 2) halyard restrainer (image of a harken restrainer attached. Having a hard time finding a restrainer that would allow rotation) 3) freely rotating block below the sheave?

    Newick Summer Salt 26: akas & sockets

    Here is what the beam ends look like after the season. My conclusion is that they are more than beefy enough for the loads. Pics (not that interesting to look at). I also had a chance to look at the boat plans from the previous owner. The beams all come from a single mold with the rear beams cut short from the outboard end. The aft beams are sealed while the forward ones are not. Layup specified: 8 plies of orcon s-500 (unidirectional s-glass, 2 plies at a bias) + 8 oz woven roving inside & out.

    Newick Summer Salt 26: akas & sockets

    Sounds like a beautiful place to go sailing. We spent 6 years in Vancouver and we still miss it. Going up the east side of Vancouver island is Maggie's dream trip although it sounds like you had a wet go of it this time around. Yes, sailing season is over and fix-it season is upon us. I'll be pulling the boat out of the water next week. It's been sitting in a sad state with the mast down since the trip while I figured out the roller furler which is done now. I've been thinking about how to rebuild the mast tiller. Searching for mast tiller on the forums actually brought up your blog. It's a rather beautifully built tiller and I wouldn't mind trying my hand at more composite work. How did you lock it in place? I don't see any lines running to the tiller in the last picture. Pictures of the old mast tiller are attached for everyone's bemusement.

    In-mast halyards on rotating rigs

    Yes, the headstay was attached to the center tab of rotating hound. My concern with using the sheavebox is that the jib halyard would exit at ~90° potentially causing a lot of wear. The picture shows the new halyard, I don't know how the old halyard ran but I suspect it was just external.

    In-mast halyards on rotating rigs

    Thanks! I was lucky enough to get a look at 3 pages of the original plans but they did not have any detail on the hounds. Hard to tell from pictures of other somersaults what their hounds look like.

    Newick Summer Salt 26: akas & sockets

    @ProaSailor Haha, yeah it doesn't look great on a desktop now that I see it. It is very natural on a cell phone or tablet though and it does have the benefit of allowing you to see more of the sail. ¯\_(ツ)_/¯

    In-mast halyards on rotating rigs

    I'm somewhat concerned about a bail+block allowing a somewhat large exit angle but I guess it's not a problem if so many others have done it before.

    In-mast halyards on rotating rigs

    It's a Somersault 26 Trimaran (more in this thread). Dismasting was due to the headstay letting go right at the top swage. I didn't notice any halyard wrap but who knows. No bails or other hardware below the sheave box right now. I can't figure out how the sheave box was ever used before, even with a 2:1 setup it seems like the angle of the halyard coming out of the sheavebox would be a problem. I can always add a new bail below the sheavebox if that's the right thing to do. I haven't had any problems with the hound so far but this is also my first boat with a rotating mast so not much in the way of other experience to compare to.
