Not in a power boat, but sail boats and in mine a motor sailor it is called -- heaving to. It is a tried and true storm tactic.[/QUOT
Yes, and any boat can get drogue, sea anchors, etc.

It IS a big difference because planes cannot just have to in the middle of the ocean, boats can, and also can use motors to sail at night or in storms.
I apologize if I misunderstood something. I thought we were in theory talking about a fully electric power boat. If the batteries die, how does it heave to? What if there are no other motors? If you are going to assume there are backup motors, that's a different condition. My point was that a fully electric boat may not have the option to just sit quietly in the sun waiting to recharge. It could be almost as dangerous as a plane that runs out of power. In fact, a plane may be less dangerous depending on the location and conditions.

The long distance ones still have a genset, just like most boats, and the same as long distance electric cars are hybrids.
Electric-powered boat/ship "just floating around" means all required schedules are thrown out the port hole... so to say. And, if the weather stays bleak of solar light for too long then availability of sustenance goods may become impacted.
Boats do have much better capability to be electric than an airplane. In that, boats can easily support/carry the added weight of secondary power sources in several different configurations of different types.
Atmospheric CO2 based Full-Cycle, Carbon Neutral liquid hydrocarbon fuels are on the verge of appearing. That will mean... generators aboard boats that may be needed to assist solar charging of batteries will be able to run without putting fossil fuel Carbon Positive new exhaust fumes into atmosphere. But, rather using fuels that are actually recycled from atmosphere to engine to atmosphere to engine - etc. etc. etc. That is why it's called Full-Cycle, Carbon Neutral fuel.
These new-source fuels will include gasoline, diesel and jet fuel. They will be fungible with refined fossil fuels and drop-in ready to work in any engine that currently uses fossil fuels. These breakthrough, atmospherically situated Carbon Neutral fuels will continue useful actions and replenishment... over and again!All that already exists , and keeps getting better, just as in cars. The Alva Yachts 65 already has 20 kW solar capacity, and 2 - 300 kWh battery capacity. Charge all day in the sun, run all nite on battery, and the genset is always there too for when no sun for a long time.
JW - You may have not realized what I was intending to relay. I was not meaning that assistant generators or other secondary power sources are new... it is the Full-Cycle Carbon Neutral fuels that are coming along... that will be very new!
For the carbon neutral folks the tech already exists.
A steam boiler with wood as fuel.
... I don't know why the US has to solve a global issue......
1. For the same reason that we don't hunt whales, make kids work in mines, and want women have equal rights. Because doing the right thing doesn't depend on what other countries do.
2. Because someone has to, and we can.
3. Because the alternative will be disastererous.
I'm not saying we shouldn't strive to reduce carbon emissions, but my point is that it's a global issue, not a US issue and we can't save to world if countries like China don't want to cooperate.
Post 133. China seems to be participating now by shutting down all pollution with blackouts.I'm not saying we shouldn't strive to reduce carbon emissions, but my point is that it's a global issue, not a US issue and we can't save to world if countries like China don't want to cooperate.
