I get hyper focused on the stock market . . . which still has 20-30% to fall.
I do NOT believe the economy will fall that much. If/when I sound overly pessimistic it is probably because I try to discuss the economy while I still have âstock market on the brain.â
That said a significant part of the cost comes from inefficient propellers that are relatively small and spin at high rpm. An efficient prop will be relatively larger, have pitch roughly in the same range as its diameter, and spin at much lower rpm.
The difference between these extremes is great, for slip in the case of many modern outboard boats is so high that the race can even become separated from the water around it creating a great spectacle yet with diminished actual thrust. The big wheel rotating slower offers a lot to push against the water with and if correctly sized often had less than 20% slip.
Slip does apparently help acceleration, btw, so itâs not all bad and can be fun since many people drive boats like they were sports cars.
Then there is the issue if sizing a fixed pitch prop for an engineâs torque curve. Briefly: a wheel needs to have enough torque to spin it, so they are not sized for the best point in the engineâs torque curves but for some place below it to have a low to high end.
There are controlled pitch props, but thatâs a whole other thing, and they can be fiddly as they need to be adjusted to the torque actually available at any speed to get the best results from them. These can be sized to permit them to use much more of the midrange torque available.
So all taken together thatâs why really old school powerboats, though having pathetic engines in terms of horse power ⌠but not torque (a 4 to 6 hp engine could often have 70 ft lbs torque) ⌠could both go surprisingly fast for having so little power (the big wheel getting that power into the water better) and yet little boats in some locations still had to hide behind islands waiting to avoid having to fight the tide.
Finally, when a modern gas engine may be gulping a gallon an hour for every 10 to 13 hp made, losing up to half of your thrust just to slip alone tends to make those outings expensive.
If anything, theyâre way up. My realtor told us that the demand is way higher than the supply.
I inherited my motherâs house. We put it up for sale on Friday, over market value, and it sold on Sunday. Now we have to do the same with my mother in lawâs house. Before these rising interest rates start to have an effect.
Do you use the stat trading system? I have a friend who uses it and does very well. I swing trade, trying to learn this system but havenât used it yet. It looks like a much easier system.
One of the big reasons I donât day trade, I canât monitor close enough. That and I donât have a big enough account⌠Was doing very well with covered calls- till the market went to crap and everything Im in dropped. Looking for bargains to buy low and ride up doing covered calls along the way.
