Renault has let construction contracts on two 500’ car carriers, primarially sail powered. They are to run a route from France to USA to St Pierre/Miquelon and back to France. The St Pierre stop makes little sense as it is quite small, unless it is just for general provisioning.

Odd looking boats.

Sounds great in theory but I suspect they will be using the 'auxiliary diesel' quite a lot to stay on schedule. In the true days of sail delivery dates were a week, or sometimes month, not within a certain number of hours on a specific day.

Life in the oceans does not seem to be doing very well:

Scientists Fear Extinction After Six Rare Right Whales Die In A Month
Researchers call for emergency protections as 400 remaining animals fight for their lives.


(factoid: "The penis on a right whale can be up to 2.7 m (8.9 ft) – the testes, at up to 2 m (6.6 ft) in length, 78 cm (2.56 ft) in diameter, and weighing up to 525 kg (1157 lbs), are also by far the largest of any animal on Earth" ! https://en.wikipedia.org/wiki/Right_whale )

A floating mass of seaweed stretching from West Africa to the Gulf of Mexico is now the biggest seaweed bloom in the world, according to satellite observations.
The algal explosion in the Atlantic Ocean and Caribbean Sea could signify a new normal, say US scientists.
Deforestation and fertiliser use are among the factors thought to be driving the growth

Sargassum sea weed forms huge mats in the Caribbean every year in the summer months. The inputs of human waste and agricultural runoffs are making this growth explosive. These vast area of mats of seaweed form an important role in the marine environment much like coral reefs. They provide structure and act as a nursery for many forms of life. When we lived in Florida and went to the beach in the summer months the tide would bring in these huge rafts of Sargassum seaweed. We would wade out in chest deep water with nets and glass jars and sweep under the seaweed collecting marine crabs, shrimp and small fish, put them in the jar and then take them to shore to show people the marine life that was in these rafts of seaweed. Recreational fisherman look for these rafts of seaweed because dolphins (the fish not the mammal, also called Mahimahi) frequent the edge of these rafts as they prey on bait fish that use the rafts of seaweed as structure to hide in. Recreational fisherman will throw lures or troll along the edge to catch mahimahi.

These huge rafts of seaweed are normal every summer in the Caribbean. They are probably now growing to enormous unusual size due to fertilizer inputs caused by humans. There is probably a tipping point when this will start to create so much organic matter that it will wreak some form of imbalance like a red tide or something. Who knows?

The centuries-old scallop fishery on Nantucket is already a casualty of lawn fertilizer runoff along the Atlantic coast. The juvenile scallops attach themselves to eelgrass, a type of sea weed growing on shallow water sand bars. The lawn fertilizer clouds the water with plankton growth and reduces the amount of seaweed available to anchor the young scallops. It is a form of habitat destruction.

dohboi-

I greatly appreciate your efforts in reporting the death by a thousand cuts now decimating life in the oceans. The scientific community, finally, is beginning to sound the alarm that unless an immediate course correction, we are at the precipice of major tipping points.

I strongly recommend the following presentation by Dr. Jeremy Jackson titled, "Ocean Apocalypse". Dr. Jackson was invited by the US Naval Academy to provide a current state of affairs regarding the health of the world's oceans. Here is the link: https://www.youtube.com/watch?v=2zMN3dTvrwY&t=128s
