Agree on the 'go fast' boat fallacy approach for defense. One article said the ghost was promoted and developed in response to the attack on the...
GHOST works with propulsion below the surface and without control issues or spiraling into the air like the second picture. But Ghost kind of...
The gas envelope appears to come from air storage tanks within the super cavitating torpedo? Supercavitating Torpedo...
Thanks DC ! My guess is that it takes more energy (wasted prop slip) during the process of quickly getting up to cruising speed (that is above...
Why does the air bubble concept work so well with 230 knot torpedoes, and mostly so insignificantly with surface boat designs? Supercavitating...
Hi Barry, thanks for your response! I think the he bulbous Bow would be immersed when the tanker is fully loaded which means it would get the...
Thanks for your reply! Hull speed - Wikipedia https://en.m.wikipedia.org/wiki/Hull_speed Just wondering if the propeller design has to be...
Curious if having more mass (and thus momentum) is helpful with efficiency with everything else (except maybe hull shape) being the same, when...
Thanks! That explains everything, ha!
Will, Last message #15 in this link references the need to Portage, it is dated March of 2016, Everglades Challenge: the Right Boat?...
Yes, it's kind of fun and interesting about the trash can part, JMHO- kind of smells like a prankster, huh.. My thought was to reference those...
That solar boat may just be testing a proof of concept and non-competitive. Human power is allowed as I recall, and if the rules allow "solar"...
Is it really amphibious, if it requires a minimum section of smooth flat Beach to make the transition? Almost all of the "amphibians" I have seen...
Maybe something like the last picture on this page? Free Enterprises web site http://freeenterprises.net/HPBoats.index.html Or these?...
Myself would appreciate any additional information/ links you are willing to release on this project or anything similar..
Yes, surface piercing props can be designed to be very efficient especially when run at low RPMs, with less cavitation, slippage, etc....
I looked up electric fence shockers, and If it could be set up like an electric fence shocker, it would not require much power, a tiny 10 Watt...
Only the craft where human life is at stake because of damage by Cookie Cutter or other sharks might be a consideration for the whiskers...
My guess is that high voltage charged whiskers hanging from the boat would work so long as the cookie cutter sharks brushed up against them,...
Most of the shark repellent devices don't require much power, if they even work ( kind of pricey $$$, for some), 6 Shark Attack Deterrent Devices...
