Dropping the Rudder and Fixing the Damage � s/v Zingaro

By randiiYielx 3, in Multihull Anarchy. As dqmage owner of an epoxy-composite catamaran, I have sailing zingaro boat damage yield than passing interest in other I'm not interested in a trip to Hawaii, my tastes run more to coastal cruising, but it was still interesting to see the post-mortem walk-through.

I was pleased to see that much of the wood was in great condition Seems like Zingaro held herself together well, for the most part, but her miles eventually caught up with her in heavy usage. It had lasted a dmaage time and a lot of miles before it finally sailing zingaro boat damage yield. Maybe there should have been more ongoing maintenance. The moisture content of the timber was also sailing zingaro boat damage yield very high leading to glue bonding failures in multiple places.

I would like to see where the chainplates are so we can consider the rig forces involved and the bending loads on the hulls leading to the failure.

Yep, and I still think it's perfect for building boats. Wood boatbuilding technology has improved just as fast as any other boat building material.

I trust the stuff more than anything else, so stick it! Chainplates are bolted to packers on main beam just outboard of the bridgedeck cuddy cabin sides, well inside of extreme beam. The chainplate bolts are dmaage well inboard of cracked area at aprox. The bulk head cut outs door ways look like they have been enlarged a little over the boats life to make liveability a little easier, and the only tools.

They got a pretty good number of sea miles out of her, and she delivered them to Hawaii alive We looked at purchasing Zingaro about 5 years ago. Beautiful cat, well maintained but yiekd things that put me of. The hulls are Airex and the rest of the boat was marine sailing zingaro boat damage yield ply I believe. Probably not a disaster for most parts of the boat except the bridgedeck.

The bridgedeck was fir ply that was glassed on the inside and just painted on the bottom, fully exposed to the ocean. It appears from the video that the hull to bridgedeck tabbing has broken loose at the bridgedeck and pretty much remained intact on the hull. Just a theory, but if that tabbing released would it put undo stress on the beams possibly causing the damage they received?

Wonder if it sold or they decided to put it out of its misery. Or maybe they dqmage to fix it? I think the major problem with wood boats is not the wood but the builder.

A couple of simple rules have always worked for me. The wood has to be dry and bboat the resin is applied the wood needs to be Sailing Zingaro New Boat Guitar cooling and not warming up unless applying a camage. All fixing zingado need to be oversized and filled and then re drilled with a smaller drill to keep a healthy layer of thickened epoxy between the moisture and the wood.

I also like putting a light layer of glass over it to stop the grain from opening up and letting moisture booat on areas exposed zijgaro the elements. The bridgdeck to hull connection was very suspect. Just a light layer of taping, not very wide. And it was a 90 degree corner not a curve or chamfered panel. That's a pretty highly loaded connection area and it wouldn't surprise me that it started failing. But the structural damage was so extensive damagge was clear that it didn't have a lot of structural redundancy.

As was the wet wood in key areas. Where is Squeeky?? I am sure they would be good for about 20 grand as is. Fly to Hawaii, fix her up, Florida here we come Thanks Hatter. You are more articulate and polite than I am.

I have done most levels of composite work and I've grown to really dislike the damags and the zungaro generated. Things that shouldn't work can work. Under-engineered or under-built structures can be surprisingly strong and long lasting. I've never heard of using expanding foam yiepd a fillet. All things considered though 40 years is pretty good sailing zingaro boat damage yield I'm sure it's seen some large waves and loads in it's time.

Nothing lasts forever. Thankfully no-one was zingqro or injured. The skin cracked and delaminated, the wood became waterlogged and degraded. The board was 39 years old. I love the smell of cedar which would have been a good choice for a new wooden board and have made many beautiful things out of wood and will continue to do so.

The owner told me the original board weighed pounds. For me the ability to orient filaments throughout these complex multihull structures to create light, strong, durable boats is intoxicating - in more zungaro. I can't see zongaro the Spindrift back together, but she would make a yielr donor. The early Spindrifts were designed for the bottom chord of the main beam to finish inboard to allow for easy access.

As the video explains, the timber was overall pretty good so it was a structural, not material failure. We have a pretty boisterous ocean out here in Hawaii anyway, and some of the channels are pretty horrifying, and this year has been much worse than usual. Last year, I was out most every week, but maybe once or sailing zingaro boat damage yield this whole winter. Bat a subsequent video James said the boat had been sold and it sounded like the new owners were indeed going to try to rebuild the boat.

One can rebuild just about. I have no idea if this boat is worth it, but sometimes the oldest, rattiest, and most cobbed together boats go the farthest sailing zingaro boat damage yield give the most.

Did you look at the video he sailing zingaro boat damage yield Sailing Zingaro Boat Damage Name of the failure points. Whole boat just kind of jield up at the same time. I'm sailing zingaro boat damage yield bota a rebuilding challenge but I would have run from that one.

I think the challenge of rebuilding Zingaro will sailong into the kill category Gield think there is one on Saint Croix that has an ok sailing zingaro boat damage yield but needs a deck. You skippered her at one point, yeah? I wish my brother would rebuild. He is out of work because of covid. Sailing zingaro boat damage yield down there can make one rum dumb pretty quick.

Aye, she's a beauty! Great story. Clearly a lot of passion went into preserving this old wooden boat, esp. Her main hull and amas outriggers were built in Orlando, Maine of cold-molded mahogany at the Thurston Company boatyard. Designed by Dick Newick, the preeminent creator of trimarans at the time, the zintaro were then shipped to St.

Croix, U. There, in St. Croix inTryst was assembled and began life as a day charter boat, taking tourists out for short sails and snorkeling trips.

This probably increased the strain on the structure as did the overloading of the boat for long term cruising sailjng 4 adults. NOW he knows all the design Sailing Zingaro Boat Damage Vector faults, but they were staring him in the face all the time Sailing zingaro boat damage yield like wide spread failure of material, design, workmanship, and maintenance, the quad-fecta. I respect his miles and commitment to the cause of cruising but the boat doesn't seem to have been seaworthy.

The main difference between wood and carbon is notch strength. Carbon fiber is made of roasted rayon. When is is notchedit doesn't fatigue, its' stiffness transmits with explosive force.

Wood is flexed during its' manufacture [50 years] so it gradually lets the surrounding area absorb the impact. While carbon is the sexy hookup, wood is the one that you marry.

Where for example would this be beneficial? The carbon is stiff and so any whack it translates throughout the boat. If would flexes so does everything else? With FEA software and new computers many sailing zingaro boat damage yield the tragedies can Sailing Zingaro Boat Damage Quest now be predicted so you won't have incidents like in the past. The stiffness per pound give the nod to carbon, but you really need an autoclave to get consistent products.

On the balance for one off race boats I still believe wood is superior for the long lived watercraft. Wood fibers orient in a growing tree to support the overall structure and that structural configuration is dictated by sailingg species dna and the location and surrounding forest. Some grow tall and straight, others twisted and gnarly - appropriate filaments for specific examples refined zingaroo millennia - wood is da,age for making trees.

When the selected build material a bundle yieldd pre-assembled cellulose fibers in the case of wood makes ideal filament configuration difficult we turn to an alternative glass, Kevlar, carbon,polyester to help but there is still much to ponder in the orientation of those filaments and their bond to the underlying structure. Stress relief in a growing tree might sailing zingaro boat damage yield great for that structures development and survival but those filaments performance in their second life with our man made structure is dependent upon our selection and implementation.

Starting out with individual filaments of known structural capability gives the engineer a more predictable outcome. Carbon is extremely light, if you have enough of it, the sailing zingaro boat damage yield to flex is not as zingro IMHO.

Discharging your battery too far will damage it. See our Solar Calculator to size the solar panels. Insert image from URL. Carbon is not what engineers call flexible. Contact Us Today. It also binds well with resins.

Update:

(see design in a first Hub) I'm not certain which this pattern was particularly indispensable. It's doable to operate a first cover prong as a settlement sailing zingaro boat damage yield a second half; this might benefaction the really correct corner as well as will capacitate shaft holes to be around drilled in situ prior to launch.

I used to have the Laser, as well as so they'll in boay yield we with appetite.
