      A Few Simple Rules   05/22/2017

      Sailing Anarchy is a very lightly moderated site. This is by design, to afford a more free atmosphere for discussion. There are plenty of sailing forums you can go to where swearing isn't allowed, confrontation is squelched and, and you can have a moderator finger-wag at you for your attitude. SA tries to avoid that and allow for more adult behavior without moderators editing your posts and whacking knuckles with rulers. We don't have a long list of published "thou shalt nots" either, and this is by design. Too many absolute rules paints us into too many corners. So check the Terms of Service - there IS language there about certain types of behavior that is not permitted. We interpret that lightly and permit a lot of latitude, but we DO reserve the right to take action when something is too extreme to tolerate (too racist, graphic, violent, misogynistic, etc.). Yes, that is subjective, but it allows us discretion. Avoiding a laundry list of rules allows for freedom; don't abuse it. However there ARE a few basic rules that will earn you a suspension, and apparently a brief refresher is in order. 1) Allegations of pedophilia - there is no tolerance for this. So if you make allegations, jokes, innuendo or suggestions about child molestation, child pornography, abuse or inappropriate behavior with minors etc. about someone on this board you will get a time out. This is pretty much automatic; this behavior can have real world effect and is not acceptable. Obviously the subject is not banned when discussion of it is apropos, e.g. talking about an item in the news for instance. But allegations or references directed at or about another poster is verboten. 2) Outing people - providing real world identifiable information about users on the forums who prefer to remain anonymous. Yes, some of us post with our real names - not a problem to use them. However many do NOT, and if you find out someone's name keep it to yourself, first or last. This also goes for other identifying information too - employer information etc. You don't need too many pieces of data to figure out who someone really is these days. Depending on severity you might get anything from a scolding to a suspension - so don't do it. I know it can be confusing sometimes for newcomers, as SA has been around almost twenty years and there are some people that throw their real names around and their current Display Name may not match the name they have out in the public. But if in doubt, you don't want to accidentally out some one so use caution, even if it's a personal friend of yours in real life. 3) Posting While Suspended - If you've earned a timeout (these are fairly rare and hard to get), please observe the suspension. If you create a new account (a "Sock Puppet") and return to the forums to post with it before your suspension is up you WILL get more time added to your original suspension and lose your Socks. This behavior may result a permanent ban, since it shows you have zero respect for the few rules we have and the moderating team that is tasked with supporting them. Check the Terms of Service you agreed to; they apply to the individual agreeing, not the account you created, so don't try to Sea Lawyer us if you get caught. Just don't do it. Those are the three that will almost certainly get you into some trouble. IF YOU SEE SOMEONE DO ONE OF THESE THINGS, please do the following: Refrain from quoting the offending text, it makes the thread cleanup a pain in the rear Press the Report button; it is by far the best way to notify Admins as we will get e-mails. Calling out for Admins in the middle of threads, sending us PM's, etc. - there is no guarantee we will get those in a timely fashion. There are multiple Moderators in multiple time zones around the world, and anyone one of us can handle the Report and all of us will be notified about it. But if you PM one Mod directly and he's off line, the problem will get dealt with much more slowly. Other behaviors that you might want to think twice before doing include: Intentionally disrupting threads and discussions repeatedly. Off topic/content free trolling in threads to disrupt dialog Stalking users around the forums with the intent to disrupt content and discussion Repeated posting of overly graphic or scatological porn content. There are plenty web sites for you to get your freak on, don't do it here. And a brief note to Newbies... No, we will not ban people or censor them for dropping F-bombs on you, using foul language, etc. so please don't report it when one of our members gives you a greeting you may find shocking. We do our best not to censor content here and playing swearword police is not in our job descriptions. Sailing Anarchy is more like a bar than a classroom, so handle it like you would meeting someone a little coarse - don't look for the teacher. Thanks.

Articulating Bowsprit Details

15 posts in this topic

Could someone please most details and pics of the mini's articulating bowsprit systems. I am building an i550 and I want to simulate the mini system in my above-deck articulating pole. I have looked at Leo's wonderful site and googled like crazy, but I havent been able to find the detail I need.

 

I intended to have the pole articulate around the forestay attachment point with a bobstay spliced through the stem to allow the pivot points to be inline, but I am looking for more pics, info, diagrams of the actual attachment/hinge/inboard end.

 

Don't jump down my virtual throat if I am getting the terminology wrong, I am figuring this out as I go.

 

Thanks for all the help in advance.

Thats the Zero solution, a very neat and expensive compared to others,...

other solution is a ss bus around your stanchion, put a ss plate on the bottom, and weld a ring above the bus. Now its fixed top and anti scratch down.

on the bus, you can weld some lips where you can put the sprit on. (bolt through) For the rotating part, just make something out of small tube that encircles the stanchion and fix it to the bowsprit. In short this is the Pogo solution, the cheapest. its looks small and not strong, but its a proven concept.

We are the builder of the Pogo 2 in the USA.

 

We will be happy to help you out. I personally just sailed over 2000nm from california to hawaii. The bowsprit worked great until 80nm from the finish when the windward guy broke off (the line was about 5000nm old :-( ).

 

Cheers

Thanks guys. I have started trying to figure how to build the saddle and arm like ColinG posted.

 

Leo- I am not sure I follow your description and I don't know what a bus is. Sorry, I am learning!

 

Jerome- congrats and the singlehanded Transpac! I just shot you an email. Thanks.

Well if you notice - that's a custom stanchion (its got a lip to hold down the rotating plate as well as an articulating piece.

Got it. Thanks. I will not have a stanchion, but will have a 6" eyebolt with a shoulder that will be the forestay attachment and on which the arm and saddle (is there better terminology?) will pivot.

Ah, that will ask for some ingenuity. Just brainstorming, no insurance it works. Get a strong eyebolt, place it not transverse but longitudinal. Use the forward part to make something rotating. Could be a bit light though. How big is the big spi on a I550 ?

 

tried a google, and found this on this forum

click on that magnen foto, post 7, and with the text before you will understand how it works. Make something similar without the stanchions :)

Thanks Leo. Here is what I am thinking, one like the arm in the picture of this i550 (not mine). It will have a bobstay and I dont think mine will stick out that far forward.

I have a 1/2" SS eyebolt with should which will go through a 1/2"+ (ID) Delrin tube that will be mounted in the arm. The eyebolt will be mounted into a threaded tube and nuts which will be permanently mounted to the stem and wrapped in carbon.

 

This method of mounting to the stem has been used on other i550s and it seems to work fine.

 

The carbon pole is an old windsurfer mast and is only about 5' long. It will be mounted the the saddle with a transverse bolt in a G10 tube.

 

The spinnaker size is not limited, some are running some used Melges 20 kites. Those are about 40m2 (430 ft2).

 

I will post some pics when I can.

 

Thoughts?

Forget the mini solution, as you do not have stanchions. the mini use a rope shock-cord system to the top of the stanchion to keep it up without sails.

Due to 240 cm or even longer poles they really need that. Will be difficult build a rotating one without the up lift. Because if you want to rotate you want to go to 90 degrees.

 

see a photo of Jerome Open Sailing:

If you want to rotate it a bit less, Imagen your bowsprit extended on deck, fix it on a very tiny traveller (with radius of course). Use a ring on your stem.

 

ps, this gravity thing of the sprit wanting to go down, on the Zero part is was setup so that if the topping lift broke, it got jammed and only pointed a little bit down. On the Pogo system it can fall in the water. not that that was a big problem for most serious sailors.

Leo:

 

That was what was initially looking to do, but the arm and saddle I posted above seem an easier solution for me to build than what Jerome has.
