    There is no record of Trump actually saying this.. This is not been found real by any large news organizations or any fact check.

    10 mill$ poweryacht capsize during launch in Anacortes

    Thanks for the report - not surprised at all. At a density of 4,050 lb/yd, 30 tons would be ~15 cubic yards? 3 yards X 5 yards X 1 yard thick, or 9' X 15' X 3'. Anyone know what the total displacement was supposed to be? This was a comedy of errors. "High density concrete can be made from natural heavyweight aggregates such as barites or magnetite which typically give densities of 3500kg/m3 and 3900kg/m3 respectively." Thats about 10 cubic yards, instead of 15...."They can also be made using iron or lead as a replacement for a portion of the aggregate. These give even greater densities of 5900kg/m3 for iron or 8900kg/m3for lead." That is around 6.1 cubic yards for iron. Normal concrete as quoted above is 2400kg/m3 or 150 lbs per cu ft. ...... "Its primary use is in radiation shielding, either in nuclear power plants or in radiation therapy units. It can also be used as ballast in offshore locations such as pipelines." http://www.concretecentre.com/technical_information/building_solutions/special_concrete/high_density_concrete.aspx

    I was assuming that was exhaust from the engines. well that is what I thought , and I didn't want too look too stupid , but it seemed a little excessive for that. Look how far the moulded line in the hull is down aft and the lower ports , at 2:50 on the vid.

    Did anyone else notice how much air was blowing out the stern as the aft deck immersed.

    I believe the ballast issues and an unstable form also played roll. How I used the example was that my boat went from highly stable so that a couple could stand in it, to if one person stood up, and concentrated all he could to balance, he would still be thrown like a circus act. At the launch angle, the aft deck (platform)became submerged, water over it , partially negating stability calc for that section of hull. Look in the earlier in the video at the rotational point on the front car, and imagine the aft totally floating, partially submerged ,up off the aft trucks and pivoting on the front car. . As a kid of 12 I had a 16 foot power dory and I used to run the bow into a hard mud bank. it would pivot side to side like a teeter totter, when you walked on it, till the chines hit bottom.

    I believe I may know what happened. I have owned 2 Grumman War canoes. They are 20' , 44" wide ,120lbs. Midship they are only 12'' deep. The coastgard plate says 10 people, 10hp. Almost flat bottomed they have plenty of tumble-home with the max width c. 3 inches up from the bottom. It is very stable. Once on my daughters 16 birthday beach party I dragged her and 6 more of her friends around Northport L.I harbor with my brothers lobster boat. I decided I wanted to flip them. I stood on the gunnel and bounced as hard as I could, they just screamed and sat on the floor of the boat. I have flipped canoes by getting on the bow in a squat, holding onto the gunnels going back and forth trying to twist the boat over, but I still could not flip them. Often a couple of us stand up to fish. First time I had several of us on the Nissiquoge river on long Island, I put the bow on slightly steep bank, you could feel the stability difference. I put my oar down to the bottom to stabilize, as I had them get off one at at time. As soon as I stood up it was like a 800 lb gorilla spun the boat. My kids and their friends howled, with laughter as I flew into the the river. I learned to be very careful when there is only one pivot point on the bow. I have noticed this making similar landfall on other vessels. If you look at the launch video, that front dolly/truck even swivels, also it is under a sharper section of the keel. The up and down side stability is provided all by the after trucks. Now it appears as an already not to stable design.If the angle of the ramp was such that the boat at some point was floating aft, and the aft trucks were no longer keeping it from heeling, It would be pivoting on one point under the front keel. That is what I thought I saw. I would agree except its been now reported that they attempted to slack the hoist since recovering the boat and it was reported that it wanted to turn turtle as soon as they slacked the hoist. As I said reported by who knows who but if that were true then there is a fundamental stability issue beyond the classic instability when supported at the ends vs across the midsection that creates the stability aspect of the hull. The other thing is that the back of this thing isn't canoe shaped in theory the wide back end should have easily provided side to side stability and with the bow either in the water or still supported one would thing the wide end of the boat would/should provide the stability needed to keep it right side up. If they had launched it bow first and it rolled before the stern section really was floating then I'd agree that the canoe effect of where the stability gets generated was in play. The fact that I used my canoe as a example is not germane to using a regular canoe as an example. Althought its ends are pointed it carries its flat bottom width far into the ends and will plane with a 3 hp. My point was how stable it is. 3 adults and 3 kids barely submerge it an inch and a half. and I regularly stand on the fore or aft decks cast fishing. Also being so wide,44", and shallow and flat most of the weight was on bottom. The point was that stability radically changed when that bow was slightly lifted on one point. I have spent a lot of time beaching boats , and I can say that V bottoms can behave pretty funny on a steep hard beach.

Also If there was a problem with all this ballast stuff, that pivot induced turning to , possibly normally less than critical angle of heel, would have been unrecoverable.

Another post on that thread Top Re: Like a Backyard Range?by wjbarricklow » Fri Jan 31, 2014 8:49 pm You're asking us to compromise. Not actually compromise, because generally compromise means you give up a little of something to get a little of something else. You're asking up to give up a choice to the government. Worse yet, you're asking people to give up their rights, to prevent something that has not yet happened since the preemption law was passed in 1987. Right now, I can take my young son in the backyard, and teach him to shoot a 22 rifle prone with CB caps into a backstop that isn't much more complicated or permanent than a BB gun target. What you're proposing is to create a law to regulate that activity. Obviously, I'd need more backstop for full power 22LR. More for centerfire handguns. I'd need even more for a 30-06. Everybody's situation is going to be different. There isn't any one type of range construction that fits every solution. To discharge a firearm at home, someone who does a little gunsmithing and just wants to fire a handgun to check function might be able to set up a clearing barrel in the garage- this can literally be a bucket of sand. I know someone who used electrical putty against a concrete wall as a backstop for standard velocity 22s in his garage. I know other people who are a little further out of town and shoot into a pile of dirt. You're proposing to outlaw this. Because unless we have an inspected, permitted range to fit every situation, it won't be legal to discharge a firearm at home. There is no one solution that fits everyone. But a set of uniform or minimum standards, enforced by the government must fit everyone, so it has to be far above my minimum standard for a backyard 22. And honestly there are people out there who probably need a shipping container in the backyard to be safe. You're asking for suggestions, but the best suggestion I can give is that people need to set up ranges that are not "reckless or negligent". And the law is already there. On a personal note, I find it laughable that you didn't ask for this attention, and yet you're willing to do an interview on CNN. And now you're telling us that since you've opened up a can of worms that has been just fine shut for the last 20 years, we need to work with you to set up some regulating body to further run our lives. I really don't know what to say. ...and they think I'm compensating for something? wjbarricklow Life Member Posts: 3175 Joined: Tue May 20, 2008 10:04 pm Location: Stuart, Florida 34997 Another post on that thread Top
