This arrangement give us the ability to swing the boom side to side and lock it in position, great for running. In addition, a special case. In case of a MOB we can swing the boom outboard and hold it in position as we the lifing tackle off the end of the boom for recovery.
The Khamsin is also used a lot by persons with disabilities, para and quads. We use the vang system to swing the boom outboard to the dock and one of the halyards to raise the boom up and down to lift the person aboard.. It's more stuff on the deck, but the adaptability is great. Gene; I did the Garhauer ridged vang three years ago. It solved a lot of the weather helm problems that some of the owners have talked about.
It was easy to install also. Khamsin's setup sounds intriguing. It sounds like the vang doubles as a preventer on the boom.
Our vang is just a line running through blocks at the base of the mast up to about mid-boom. It doesn't add much control beyond what we get from the main sheet. Regarding preventers, we rigged a line from where the sheet attaches to the boom and string it through the lazy jib sheet block when sailing downwind wing-on-wing.
It seemed to work quite well, allowing us to ease the boom back over when we had to shift the main. I've also read recently about the concept of flying double jibs for downwind wing-on-wing sailing as an alternative to spinnakers. It sounds intriguing. Has anyone tried the configuration on a Morgan 38? I think we might have a second track on our rollerfurling. I'd been wondering what that was for until I read about this. Fair winds, Rob www. Rob, across the Atlantic, I did wing-on-wing with my old Hyde 2 track furler for about 18 days.
This vang also offers a coil spring as the return mechanism. It consists of completely anodized aircraft grade aluminum tubing with solid aluminum machined ends. Purchase block and tackles are always included, varying from to depending on boat size and sail requirements. As with all of these systems, mast brackets and boom lugs are purchased separately. Selden Rodkicker vangs have also been around a very long time and are rigged on many different styles of boats. They also use a very attractive rectangular extrusion instead round tubing like Forespar and Hall.
The ends are made of cast anodized aluminum like Forespar. Purchase block and tackles, mast and boom brackets must be bought separately. Hydraulic Vangs — Amongst the various hydraulic vang manufacturers you will see very similar design, functionality, and construction. It seems that Navtec, who also recently closed their doors , was the grandfather of all sailboat hydraulic system and cylinder design.
The three big players left see links at the top of this article all have their own unique features and benefits, but are for the most part based on the same Navtec design. Whether we are talking about a double acting push pull vangs reserved primarily for larger yachts with heavy booms or gas return vangs, the gist is the same.
The big deal is that all of these hydraulic vangs require the boat to be plumbed with hoses, a reservoir and a control panel that houses the pressure gauge and pump at a minimum.
Besides just a basic vang cylinder no plumbing, brackets, lugs or panels costing as much as the most expensive mechanical vang mentioned above, these systems HAVE to be professionally installed thus making them the most expensive, but also the most robust option, by far.
All rigid vangs especially when properly installed and maintained will last a very very long time. One thing that all vangs require, regardless of whether choosing a simple block and tackle, mechanical, or hydraulic system, is for them to be installed properly; ensuring a properly mounted mast bracket and boom lug, rigging the vang in the correct orientation not upside down , all the while achieving the appropriate boom to vang angle approximately degrees.
This will ensure functionality, longevity and ease of use. Have a question about which system might be right for you? Some friends at the marina helped hold the boom while I drilled and tapped the first holes. I love how it supports the boom even when the topping lift is slacked. Rigid Boom Van If you have a good rigid boom vang you can get rid of the topping lift and save the leech of the mainsail from chafe etc.
Les Andersen. I was told I needed to isolate the brackets from the aluminum. Not sure if really necessary. Thanks in advance.
Steve Dion. Work In Process. What about under moderate or heavy conditions? Does the upwars pressure on the boom screw up the sail shape? I'm thinking this gives us one more thing to deal with when going upwind. That's not necesserally bad, I just want to know the impact before I install one. Set the sheet, ignore the vang. Right but vang sheeting with a strut is no different to vang sheeting with no strut.
You play the vang line, and the strut spring accommodates the changes in length. And based on the first post jarcher doesn't vang sheet upwind. What size boat? Why not go simple and use a boomkicker?
Then you get rid of the topping lift. Light and an easy install. I know. No we don't vang sheet. The boat has a traveler so we doe the conventional control twist with sheet and angle with traveler method. Thanks everyone, I'm trying to decide on boom kicker or regular rigid vang with a tube and a spring. The price on the kicker is sure right and my rope vang is fine. If you decide on a rigid vang: the ones with compressed air are a lot nicer than the coil spring ones - and you can adjust then far better.
Thanks I'll look for one of those. Let me guess though, they cost lots and lots more? Well sailing is sure not cheap! Then what do you do when the mainsheet car is at the end of the track and you still need to control twist?
I bet you are vang-sheeting in some conditions, and just don't call it that. I have a solid vang and I like it because it controls both up and down movement. It has no spring, which I also like because it means that I can lock in the correct amount of twist. If there is a lot of chop the boom, which is pretty heavy, can bounce up and down changing the twist. The solid vang locks the trim in in these conditions. Okay true, when were reaching or lower we use the vang, but I thought the term "vang sheeting" was limited to use for upwind conditions, so when you're using the vang to control twist even up wind.
