    Inverted buoyancy

    Of course, the practical applications are obvious and are left as an exercise for the student.

    Electric Fan Drive?

    The adjustable ones in the vid look to me like they work similarly to autoprops.

    Trump faking it?

    ... The drug maker Regeneron said on Wednesday evening that it had submitted an application to the Food and Drug Administration for emergency approval of the experimental antibody cocktail that President Trump had praised just hours earlier without evidence as a “cure” for the coronavirus.

    If you take the battery off of a little Torqeedo or similar it's easy to move around and stows in a compact space. If it stowed under the side deck and the battery was on a extension cord so it could stay put when in use then swinging the motor onto a side mount might be easy enough.

    Depends on what you're looking for, but they're pleasant to drift around on. You sit so close to the water that it feels like things are happening. Aux power is a quandary. Bull City's setup might work. I'd have the folks sit in the boat to make sure the seats work for them. The Cape Cod Bull's Eye is very nicely done but a little more clearly FRP than some of the other versions. FWIW, my great aunt sailed one into her 90's.

    Solar to Shore Power inlet

    Uses the grid as a buffer like household solar? Not sure about the details of how that might work in a marina...

    Hurricane Delta

    I think you're wise to be skeptical. We're in between recon flights but, again, Levi does a nice job of rendering the data: https://www.tropicaltidbits.com/recon/

    I'll second Levi as well worth watching. Also, he has very nice renderings of most of the important models on his web site. Tropicaltidbits.com -> Forecast Models -> Hurricane: eg. https://www.tropicaltidbits.com/analysis/models/?model=hwrf&region=26L&pkg=mslp_wind&runtime=2020100612&fh=6 The navy does a nice chart: https://www.nrlmry.navy.mil/tc_pages/tc_home.html If you're on lower bandwidth internet this link is direct to Delta's folder of pics and bypasses the very bandwidth intensive official sat viewer page: https://cdn.star.nesdis.noaa.gov/FLOATER/data/AL262020/

    2020 Hurricane season

    ACE seems problematic to me. It assumes max wind^2 α energy. Despite its name it doesn't measure energy directly. Flip side, we're at something like cyclone 26 this year which is already over twice the typical number.

    Trump faking it?

    Yep and he can downplay the severity of covid while at the same time plugging Regeneron.

    On small boats with low topsides it's hard to get both nice seats and a self bailing cockpit.
