Barry Pyeatt Posted May 28, 2003 Posted May 28, 2003 OK Mike, Counterweighted mast with tabernacle. Maybe this will help, maybe not. But it isn't original to me, I saw this some time ago on a boat up in Michigan. It has been helping that ole' timer with his boat for years. So I drew it up hoping maybe it will add some fuel to the calories buring in the gray matter. It you can use it....great! [attachment over 4 years old deleted by admin] Quote
Steve Tarry Posted May 28, 2003 Posted May 28, 2003 Now, that's a good idea, Barry. As one of the aforementioned old timers (with a bad back, to boot) I'm going to remember that one when I get to that stage of construction. Quote
Mike Pennington Posted May 28, 2003 Posted May 28, 2003 Your definitely the Man, Barry! I was just responding to my original post, and thought I would jump over to give you a yell. Now I think I can work with this, sure beats what I was planning. I will buy the materials tomorrow. And I get to use my new hinge with this design. I don't think I'll even have to buy any lumber, the plan should work with what I have. Thanks Barry, After this little mod, I am going to rebuild my hatch and sliders as to the drawing on BYYB. Barry you can come up to my house for dinner any time you want, okay? Quote
Barry Pyeatt Posted May 28, 2003 Author Posted May 28, 2003 Glad I could help Mike. Dinner...as long as it isn't that waterloggedd moose! My brother and sister-in-laws live in Wasilla. Visted them a few years back and toured the State for 5 weeks. Had Moose, Caribou, Bear, tons of trout, salmon, crab and halibut. Came home with 4 big coolers full of frozen food. Also got care packages curtesy of a NW cargo pilot neighbor that would pick the coolers up and take them back for refills. So...one of these days...who knows? I may just drop in! :roll: If you are ready for the next modification. I have the bow grating drawings just about ready. This is actually really good therapy for my eyes. I"m finally beginning to do some detail work. Quote
Mike Pennington Posted May 28, 2003 Posted May 28, 2003 Oh No! How could that one slip my mind? I am ready to extend the bow, my son was griping today while I made him hang five and reach Quote
Barry Pyeatt Posted May 28, 2003 Author Posted May 28, 2003 Ok, I'll finish up the drawings and post them. :wink: Quote
Mike Pennington Posted May 28, 2003 Posted May 28, 2003 I did finish up the Portholes :roll: lets see, how many years has it been? I definitely got to finish that hatch too! Mast First! :twisted: Quote
Barry Pyeatt Posted May 28, 2003 Author Posted May 28, 2003 My goodness, an ocean liner! :shock: Mutch better than the Battleship look. You keep this up Mike, you might just get around to doing the interior too. That looks great! Quote
Mike Pennington Posted May 28, 2003 Posted May 28, 2003 Naw! :oops: If I could frame in a sea bunk I might go for that. Heck, I still got to finish the electric system! Like I said, a work boat in progress. I got a big sail planed for the second week of June. Major trailer sailing. A little bit everyday and I might be ready by next summer. Quote
Craig Posted May 28, 2003 Posted May 28, 2003 Those ports look good Mike. Berry thanks for posting the grate drawing. Later I will be trying the cutter rig and will need the extra reach that design allows. Quote
Sailor3356 Posted May 28, 2003 Posted May 28, 2003 Wow :shock: thats a lot of port holes. You did a nice job Quote
SeaEagle Posted May 29, 2003 Posted May 29, 2003 A question regarding the counterweight for the masts. Has anybody considered what the impact is to the center of gravity on these small boats is by adding weight above the waterline. I only ask because I've been reading the other topic re: Ballast. We are probably not talking about a significant amount - but I know that adding a pound at the top of the mast is negates 8 pounds of balast at the bottom - levers and all that. Just thinkin aload now :? Quote
Knut Posted May 29, 2003 Posted May 29, 2003 SeaEagle wrote: "Has anybody considered what the impact is to the center of gravity on these small boats is by adding weight above the waterline. " That is exactly why my plan is to build a lightweight mast (which will be easy to raise even with a less than 100% back) and the positive net effect of ballast will be all the better. (Or it reduces the need of any ballast in the first place). :roll: Quote
Barry Pyeatt Posted May 29, 2003 Author Posted May 29, 2003 Actually yes, there was considerable discussion and thought put into that arrangement by the owner of the boat and a friend of mine, a Marine Architect. The disadvantage of adding weight above the deck was a relatively small consideration compared to the advantages of being able to lift the mast to step it. My friend felt that most often the disadvantage would be offset by cooler with ice/beverages, other gear, etc. that were aboard when sailing. Certainly the advantage of being able to simply lift the mast enough to begin to have some help would be of primary importance. He recommended an additional mechanical advantage to help. He suggested adding a simple lightweight 2-1 block and tackle to the gear. This is hooked onto the forestay eye on the bowsprit, and the other end of the block is hooked onto the forestay shackle. The line is run back to the cockpit and once the mast is raised above the direct line to the boweye the block and tackle take up the work. Easy to manage. Now Capt. Jake has done essentially the same thing with his Weekender. But I think with a Vacationeer mast and all the rigging that this could make raising the mast quite simple for even the "vertically challenged." But certainly easier for all of us that have that "age" or "reach" challenge. [attachment over 4 years old deleted by admin] Quote
Johannah Posted May 29, 2003 Posted May 29, 2003 The version of this system that I have been doodling over the Winter include some lateral connections (maybe to the chainplates) to counter the forces resulting from the mast flopping to one side or the other. I found a fairly elaborate rig on a website which looks worth some fiddling for the added safety, but can't now find it on the hard disc. If I can locate the set-up, I'll post it again. Quote
Mike Pennington Posted May 30, 2003 Posted May 30, 2003 When I am not around for a day or two, it means I am getting lots of work done on the boat or I am sailing :roll: Of coarse once my four day work week begins, I got lots of time to blab while at work. I hope! :wink: Believe me, after sailing the Vacationer for, This makes three summers, the boat can use some weight up forward. The Vacationer sails best with a deck hand up forward. Tacks better, crosses over better, sails closer to the wind. One can notice this difference by just sending a man forward verses bringing them back to the cockpit. If racing, I 'll send two crew members up forward and the competition better get out of the way because I will steal their wind My thought for the need of the counterweighted mast, and thanks again for the input you all, was to add weight forward constructively. Not just crew sitting on the deck or wieght in the forepeak. With the added sail area I am not really worried about my boat weighing to much, either. Dang, I guess I better get to work on the new hatch and sliders, too, after looking at that pic! :oops: Quote
Craig Posted May 31, 2003 Posted May 31, 2003 Good point Mike. You could lay the weight of the mast on deck and never notice the diffrence with the Vac. Photos please.... Quote

They basically attach a spinnaker pole to the base of the mast at a 90 Quote
waynemunro Posted June 10, 2003 Posted June 10, 2003 sorry to dredge up this old thread, but I was thinking about the mast the other day when cutting out my one, and I was wondering if anyone has considered putting a rotational spring into the hinge joint? I would be surprised if this is an original idea, but have seen no discussion on it. I would have thought it would be possible to design a joint which has a sufficiently strong spring that pretty much balances the mast when it is folded down, and the pre-load could be worked so that it has minimal force on it when the mast is up, surely then putting it up and down would be a breeze... and the system need not be that heavy so there are no weight problems as with a couterweighted system ?

Barry Pyeatt Posted June 10, 2003 Author Posted June 10, 2003 Are you thinking about a spring loading like on the head of a garage door? :? Quote
