Everybody should find a way to email the today show, I will when I get on home computer that's bs and needs to be corrected,
I haven't stopped thinking about these guys and hopeing both make a full recovery |

I'm glad to hear Mike should make a full recovery, they are both very, very lucky to be alive! Thank goodness the boat dissipated so energy in the air and by dragging the sponson during the flip, not to mention the angle of impact going in on the starboard side like that certainly helped these guys survive. The super tough carbon epoxy construction held up amazingly well, but that layup and canopy design would have been no match for the hydrodynamic forces that could have very easily have ripped the canopy right off had the angle of impact been different.
It's easy for us to say that canopies need to be built tougher, but I don't think most folks understand the hydrodynamic pressures involved at these speeds. Once the water has penetrated or breached the hull or canopy, it works like a hydraulic piston... even the best carbon epoxy layup and through bolted 1" thick Lexan doesn't stand a chance. Sure a structure could be built to handle these forces, but it would look be constructed and weigh more like a submarine... hardly practical for a light weight race/pleasure boat. Detachable safety capsules are probably the safest and most practical way to approach this, but I'm not sure how feasible that would be for these dual purpose boats... although something certainly worth considering for all out race boats like the turbine powered Mystic's running north of 200 mph. Another thing that was brought up earlier in this thread was active stability control. It's worth mentioning that I believe AL Copland's Phenom was built with this technology in mind. I don't know if the software was ever fully tested or perfected, but the front wing on that boat was designed to work as a computer controlled stability management system. In theory it's a sound principle, but in practice I would image getting all the algorithms correct for the dynamics of running high speeds of the ever changing conditions of offshore racing would have to be an extremely challenging task at best... designing and implementing such a system is likely way beyond what most in the resin bucket industry are likely capable of doing without a lot of help from a team of engineers, and even then there would no doubt be a pretty good learning curve. Again, I wish Mike (and his family) a speedy recovery and hope the injuries aren't too serious. |

Man that's some serious air. Very fortunate to have survived.
Time to step up into Ejection Seats LOL - Gotta Love OSO! I hope that Outerlimits, Mystic and others are taking notes right now. I am sure "we" the OSO peanut gallery can collectively solve catamaran flip overs by Friday. So far we've come up with these solutions: canards parachutes upforce downforce blow thru catamaran decks detachable pods ejection seats under trim over trim stripper poles Of the 40,000 views and 170 replies probably less than .001% of us build boats, have engineering degrees, or have worked with aerospace or hydrodynamics. In the end, I love this forum, we truly believe we can solve the worlds problems and catamaran flip overs... But in actuality the most any of us can really contribute is "dude, hold my beer" - And even that will probably turn into a "Fountain" thread. LOL The irony behind it is that this thread had 40,000 views and I will bet that is 40,000 people that hope and pray the guys on this boat get well very soon. That is a lot of positive thoughts and prayers headed in the right direction and pretty darn cool! |
After Mike has recovered we can start a thread, on Cockpits and Control systems, 20 years ago I had Cockpit adjustable Canards, which were applied to control attitude as there mounting position were well forward on the sponsons, they worked fine, now the pressures like I said we did a thread, but when you have "Experts" chime in who never built anything OR did the Basic calculations it becomes imposable to get the Point across , Best Regards Mike that was one Hell of a ride you took, Well past a "E" Ticket !

Not sure if anyone caught the Today show this morning on NBC, but they announced that both occupants flew out of the boat during the crash. If you're going to show this on THE NATIONAL news, GET YOUR FREAKING FACTS STRAIGHT YOU JACKA$$ES!!!:bong:

I am far from a party pooper and love high powered machines and fascinated with all things fast and powerful! I would like to see all the boat manufacturers get together and combine forces to come up with some kind of fail safe system to prevent the high speed blowover. Something simple and cost effective.... Like a spoiler up front or a way to dump the high pressure air under the boat while simultaneously auto-deploying a drag chute from the transom?? Something to prevent an impending blowover and safely slow the boat down?
Back to matters here, there have been some good points throughout this thread. As for pitch stability, I am sure an algorithm can be written that can provide a major reduction in chance of blowovers without inducing a stuff. A comment a few pages back was yes we can make the boats safe for the current speeds but then we will just put more power to them to go faster. Now add in an active pitch stability, that soon will no longer be a safety device but will now be used to actively raise the hull to reduce drag, OK add active roll stabilization and we soon will be lowering the drives so we can propel the boats with the hulls not touching water. Yes to those saying nuts to all this, We do need to keep up with safety, some of my background has been in accident investigation, this has been in both aircraft an race cars. I have learned allot here. From that I would love to see how seats and harnesses are mounted. Some pictures I have seen of the suspension seats are a bit frightening. I started my comments many pages back with the fact we will see major improvements in crash safety due to this one being survived and that Mike survived the horrors of going through this. I expect these improvements will be addressing seat and belt mounting as well as the containment shell around the occupants. Having closed cockpits is of little value if they do not hold up at the current operating speeds not to mention when we see these boats touching 300 in the near future. God forbid when electronics come into play here. Sorry for the lack of providing quotes and references, I just do not have the time to do so properly. |
Thank you for posting the e mail address, I e mailed them.
