How to knock up a mast from a lamp post � Yacht Mollymawk

Your boat must be in the water. Begin by just slacking off all building a sailboat mast design the side shrouds as evenly as possible, so that all stays can be adjusted by hand. Once loose, try and adjust all turnbuckles so that they are pretty much equally open or closed from port to starboard respectfully.

Also go ahead and line up the cotter pin holes if present in the studs so that they are in a pin-able position. Now is also the time to balance out the threads, between the upper and lower studs of the turnbuckle, IF they are not. Saiilboat, loosen all halyards or anything that may pull the mast to port, starboard, forward or aft.

Check by desigj up the backside of the mast to see how straight your spar is desing to. You can take a masthead halyard from side to side to ensure that the masthead is on center.

Cleat the halyard and pull it to the tape mark on one side, mark the halyard where it intersects the tape on the shroud. Now do this to the other side, the mark on the halyard should also building a sailboat mast design the tape similarly. Please note: when the mast is equipped with sailboar and starboard sheaves, instead of just one building a sailboat mast design sheave, it will appear slightly off to one.

Buulding keep this in mind��. Using the upper shrouds as controls, center the masthead as much as possible using hand tension. Some masts are just crooked. If yours is are crooked, it will reveal itself when you loosen all of the stays building a sailboat mast design halyards initially and sight up the mast. Although desifn should use hand tension only, you can use a wrench to hold the standing portion mat stay portion of the turnbuckle.

Tune the mast from the top shroud on-down, making sure the mast is in column. Remember: as you tension one shroud by adjusting the turnbuckle, to loosen the opposing shroud the same. Once the mast drsign fairly straight from side to side, tighten the shrouds all evenly using tools for tensioning. Typically, for proper tension, the shrouds should be tightened using these guidelines; uppers are the tightest, and then fwd.

Now you can desibn the aft most backstay s. If the backstay has an adjuster it should be set at a base setting lbs. If the backstay simply has a turnbuckle then sesign should be tightened. If there is no aft bias, too much, or the mast is inverted leaning forwardthen the forward most forestay s will most likely need to be adjusted to correct. Tension Gauge! Here is a little vid from our friend Scott at Selden Masts click the link then hints and advice for more info on rig tune�.

Is building a sailboat mast design mast fractionally rigged, only has a single set of lowers or is just plain different? Be sure to leave any questions or comments. I have a Alberg On a starboard tack the boat has more weather helm than on a port tack.

I have not been able to achieve a balanced helm on either tack. New full batten main, new roller furl genoa. Other than the boat being evenly ballasted from port to starboard, e. A crooked mast or poor static tune can result in the boat sailing differently on both tacks.

A good way to test this is either sighting up the mast at the dock to ensure that the mast is relatively straight side to side maast in column.

If notice that with the traveler in the same position on each respective tack that the sail is bubbling or flogging more on one tack than on the other, it is likely necessary to re-tune the mast. This can be done at the dock by following the guidelines in the article once the everything has been appropriately loosened to tension.

Nothing special that I can think of. Just follow the guidelines in the article. From what I can gather building a sailboat mast design are only a single set of lowers correct? Are the spreaders aft swept at all or just straight out? If you are interested in optimizing sail tuning, like in racing situations: higher wind sailing conditions will desire more tension on the shrouds, a bit more tension on the lower than the upper, but only slightly; and in lighter winds loosen them up a bit, a tad looser on the lower than the upper.

Thanks for the question. First let me say that a tension gauge is not a must for proper tuning, more for tension recording and also not exceeding max tension which is typically hard to achieve without additional fulcrums or wrench extensions.

Having said that, if you know that you need one simply search google for ddsign tensioning gauges. Perhaps they can provide a sailbost on their process for you to be able to make rigging adjustments over time. Nice article. I have a Mirage 27 the Bob Perry design. I have been tuning so that tension on the lower and uppers is the same and trying to set them so that as you say the leeward shrouds are just slightly slack.

But how do I induce mast rake? I building a sailboat mast design a split backstay with a purchase on the adjuster; building a sailboat mast design the mast have rake even with the adjuster off?

You will need to lengthen the headstay and shorten the backstay. This can be done a few ways either with turnbuckle adjustment or actually shortening and lengthening cables, sometimes you can add or remove toggles.

Building a sailboat mast design we prepared, we found that the Cap Shroud building a sailboat mast design Intermediate Shroud were clamped together at maast four spreader ends. Anyway, as I am learning how to tune my rig, it seems to me that these clamps would prevent me from tuning the cap shroud and intermediate separately and building a sailboat mast design Thoughts? Should I remove them and re-tune the rig?

Drsign it is a double spreader rig I take it? The upper shroud wire should run freely through the first spreader, or the closest one to the deck, and be clamped at the top spreader. The intermediate shroud wire should be clamped building a sailboat mast design the lower spreader.

Before stepping, if this was done correctly, both upper spreader and lower spreader should be clamped equal distance from sailbot mast attachment point, when looking at building a sailboat mast design mast from port and starboard. In other words, you should measure the distance from where the upper shroud attaches to the mast to the end of the upper spreader and it should be the same distance on the other side, port to starboard.

Then the same goes for the intermediate shroud and the lower spreader. The upper shroud should run freely through the lower spreader although it is covered by the clamp, but not actually clamped at the lower spreader, j ust the top one.

If all 4 spreaders are clamped equally port to desivn. You should be good aa tune from. The spreaders should show a slight up angle, to be specific slightly more up at the upper spreader than at the lower, but all of them should be just ever so slightly pointing up.

Sailgoat even want to think about clamping them building a sailboat mast design higher than that before tensioning, as this will pull them down and into their preferred angle, just slightly up. Specific angles sailobat really only determined on the spar builders drawing and vary for saolboat to manufacturer.

Eailboat it is pretty clear where they want to sit. With the shrouds loose if you find that angle that appears to be the right one, and push them up slightly from there then clamp. This will allow them to be pulled down aailboat once tensioned.

Have further questions? Give us a callor email us sales riggingco. I have a Catalina eesign rig with single swept back spreaders and an adjustable backstay. My questions are: how much rake, tension on cap and lower shrouds and on chain plate should cap shroud be forward and lower aft. I am racing and want the best performance. Thanks for any help. If the two shrouds are on the same plate, right next to each other, and the pin holes are the same diameter, sialboat the plate is configured in a fore and aft configuration, I would choose the aft hole for the lower shroud and the forward one for the upper shroud.

In terms of specific rake, you will need to look towards the maker of your sails and or the boat manufacturer. I discuss how to measure rake in the preceding comments.

For building a sailboat mast design I would start off with a good static tune at the dock buuilding following the points bullding the article.

Be sure to use either Velcro wrap style cotter pins or simply lash the upper and lower shroud turnbuckles together to secure. This will give you access to removing the pins or lashing while sailing and adjusting sailblat stays.

From there building a sailboat mast design will need to sail tune for that days specific conditions, your shrouds will tell you what needs to be tighter and looser.

I have answered how to do this a few times already in the comments below, please take your time to peruse sailboay comments section to see what sail tuning entails.

Doing this will always ensure that the cable tensions are set up ideally for the conditions and the boat can be sailed at maximum potential. Do this by going hard on the saibloat and checking to see if the leeward shrouds are just starting to dance, this is ideal. deslgn they are swaying about they are too loose for the current conditions. If the leeward shrouds are tight, they may be a touch to tight.

Tension and loosen as needed; count what you deesign and to what shroud, then tack and do the same to the other. I am trying to tune a Hallberg Rassy HR36 masthead rig. The rig has two in-line spreaders. Hi Bryant, good question. Once proper alignment and centering of the spar has happened static tuneand building a sailboat mast design are perhaps a hair tighter sailbiat hand tight on all shrouds, you can begin to tension things building a sailboat mast design a percentage of breaking strength.

Do this by using the cables at the deck and use their diameters to determine the tensioning. Does that make any sense? With that in mind there is a range of acceptable tension from light air to heavy air.

Thanks you for the clarification regarding the V2,D3 and D2 load eesign. The sailbpat information I could find regarding tension on the D2 drsign that is did not have to be tensioned .

The plans flutter out on the dining table and quickly there arise intertwining shivers of heady anticipation and well-founded fear. If there are 10 pages of plans promising breathtaking beauty, within them are things the prospective boatbuilder does not know how to do, ranging from water-sealing the deck hardware to somehow turning a 25ft spruce mast.

Beyond the technical issues, the awestruck amateur rightly wonders: Do I have the character�the perseverance, the capacity to surf the waves of elation and despair�for the year or three or 10 this magnificent creation will demand? As many production builders have evaporated from the underft class, a tide of professional designers and naval architects has flooded the void with sophisticated plans for amateur builders.

Modern materials�plywood, Building A Sailboat Mast Analysis fiberglass and epoxy�make it possible to build lightweight, rotproof and prodigiously strong composite hulls through several techniques, most of them simpler than traditional plank-on-frame. In just Building A Sailboat Mast Assessment the last few years, many designers have also started producing kits consisting of a building jig and all the hull panels and bulkheads through the technology of CNC computer numerical controlled routing.

The jig guarantees precise alignment, and the panels are perfectly cut to plan. That said, the logical and practical arguments against building your own are hard to beat back. An inexperienced builder probably will not end up with a boat whose functional details are as well executed as those of a production boat that has undergone years of design refinement.

A used fiberglass boat in decent condition can be found for a third to half the cost of parts and materials for a comparable home-built boat. Building a boat from plans or a kit is well within the scope of a reasonably competent DIY-er.

I am a serial boatbuilder, however, with enough experience to know better if knowing better would enhance my life. This is my sixth build; preceding it have been three other sailboats and two kayaks.

I never expected this would happen, but what started out as an experiment in building a complicated toy became a life-changing experience. So it is for many amateur builders. With the dream, of course. And then whack it down to realistic scale. While there are inspirational stories like that of Roy Jackson of Bainbridge Island, Washington, an advertising executive who began building a 43ft schooner in and finally launched it in , at the age of 78, there are many more where the overambitious dream ended as expensive firewood.

Some designers post expected building times for various boats in their catalogs. These are, without exception, laughable. For an honest estimate, multiply by two or three. For the record, my first boat, a 13ft 6in sailing dinghy, required hours.

My second, a 19ft gaff sloop, consumed about 3, A friend in British Columbia took 6, hours for a meticulously crafted 23ft Bermuda sloop. The amateur will be surprised to find how many different skills have to be learned to build a sailboat. For a composite hull, you also learn fiberglassing and filleting sculpting coves of thickened epoxy to strengthen joints such as bulkhead-to-hull , and good fiberglassing is not easy.

When I arrived at this final step on my complicated gaffer Nil Desperandum I was lost in the woods�the plans provided little illumination�until I phoned Sam Devlin, the designer, and told him I was about to turn the job over to a professional.

I digested a book on rigging and spent days prowling marinas in the Seattle area, camera and notebook in hand, studying how boats in my size range were rigged. Finally, I visited a chandlery where an extraordinarily helpful associate combed through the plans with me for two hours, patiently advising which block, shackle, eye, cleat and line was appropriate for each job.

It took a couple of seasons of sailing to fiddle the rig into top form and reliability, but it now works admirably�and I have only low-grade trepidation for rigging the next boat. The step from dinghy to cruising boat is not to be taken lightly; new complexities present at every turn.

How does one execute the corners of the trunk cabin? Taking this extra step cut against the grain of my impatient nature, which was another benefit of doing it: vocational rehab in learning patient and methodical work.

For example, if your dream is a compact cruiser in the 19ft to 22ft range, the designers listed in the sidebar offer 30 different options, including Bermuda sloops, gaff sloops, yawls, catboats, a cat-ketch and even a trailerable schooner.

Construction regimes include traditional plank-on-frame, plywood stitch-and-glue, plywood lapstrake and cold-molding. I have built hulls using various methods, and in my opinion, stitch-and-glue is the most amateur-friendly.

Its only drawback is that seriously curvaceous shapes are not possible, and some designs�certainly not all�look a bit slab-sided. The most beautiful Sailboat Mast Manufacturers California Dvd small boats may be lapstrake: the parallel flow of sweeping lines creates a visual rhythm that makes the boat seem like an organic creation. I thought it prudent, for example, to build positive flotation into Nil Desperandum, so I turned 14 cubic feet of hull crannies into watertight air compartments, providing lb of flotation to counter the lb of ballast.

Even a modest daysailer will force you to surf a cycle of elation and discouragement. And if you are to keep going, you have to figure out a way to manage it, building a reservoir of perseverance that may seep into other areas of your life.

You learn that perfectionism is not your friend, so you let go of the vision of uncompromised beauty you held when you first spread out the plans on the dining room table. Oddly enough, this surrender will also make you happier, as you learn to separate the tasks that must be done right from those merely built as a projection of ego.

You will gain confidence in yourself at the same time you plumb new depths of humility. The detailing of Waxwing would blow any competition out of the water. The oars, for example, stash elegantly under the floorboards. A mizzen, complementing the balanced lugsail, makes sail balance and heaving-to easy. The mizzen sheet, in an exquisite innovation, runs through a hollow boomkin that Hartmann devised.

Hartmann, 59, lives in central Vermont and works as an emergency physician. It took 11 months of steady off-hours work to build the boat, starting with a kit for the hull. He commissioned Vivier to draw the mizzen�heretofore the Ilur featured a single lugsail with optional jib�and undertook extra ambitions such as designing a bronze mainmast collar for a local foundry to cast. I give Vivier all the credit.

Steve Stromberg, a year-old firefighter from Sailboat Mast Manufacturers California Uk Bainbridge Island, Washington, is another serial boatbuilder with half-dozen sailboats and kayaks behind him.

He seems to have an innate need to keep raising the stakes, challenging himself more with each boat. The next one, he says, will be the 24ft Fenwick Williams gaff yawl, a 9,lb, plank-on-frame cruising boat. What has he gotten out of building boats?

The act of massaging wood into a functioning boat is my form of meditation. Amateur boatbuilders sometimes find it difficult to put into words, but most of us have found that in various ways, the boats build us.

We build patience and focus and character through the vital tasks that involve their structure and seaworthiness. Building a boat is replete with those choices, and making them faithfully is like exercising a muscle. Brooks Boats Designs brooksboatsdesigns.

Chase Small Craft chase-small-craft. May people desire to develop the boat of their dreams but don't know where to begin. You need not be an authority at boating or navigation to construct your own boat. It only takes dedication, a operating knowledge of the tools of the trade, a good strategy for building their boat. All kinds of wood boat plans can be found directly from boat builders who focus in developing specialty boats and making boat ideas particular for wooden.

There is also a great deal of information accessible on the internet. Numerous ideas can be found at no cost. But as with anything else, you get everything you purchase. Master boat builders offer high quality boat plans and designs to get a fee. Some boat builders also provide texts and manuals and include on-line or telephone assistance with the buy cost of a strategy.
