 To allow them to enter these ports, modern sail ships might use lifting keels or have a flatter bottom, no keel fin, with daggerboards to provide that control while being able to lift up and cross into shallower water. To allow them to enter these ports, modern sail ships might use lifting keels or have a flatter bottom, no keel fin, with daggerboards to provide that control while being able to lift up and cross into shallower water.

 Motor vessels can make do with a higher center of gravity and much lower angle of vanishing stability (AVS). This is the point at which the vessel will capsize and stay inverted, thus sinking it. That’s because they don’t have sails making it easy for the wind to tip them. Sailing ships tend to lean more while underway, so they can’t pile containers as high. Motor vessels can make do with a higher center of gravity and much lower angle of vanishing stability (AVS).

 Current kite rigs can be sailed within 50 degrees of the wind, meaning they tack to go upwind, like a ship with sails. Kites can be adjusted manually or by an automated system.  Current kite rigs can be sailed within 50 degrees of the wind, meaning they tack to go upwind, like a ship with sails.

 Electric ships are looking much more practical than I would have expected – getting there seems to involve reexamining how we use ships, as well as adjusting to use battery tech that makes sense for ships (as opposed to cars) https://austinvernon.site/blog/batteryships.html Electric ships are looking much more practical than I would have expected – getting there seems to involve reexamining how we use ships, as well as adjusting to use battery tech that makes sense for ships (as opposed to cars) https://austinvernon.site/blog/batteryships.html

 **[[https://issuu.com/international_windship_association/docs/iwsa_-_small_vessel_publication|The IWSA Small Windships Publication]]** has tons of info on the sub-500GT range of smaller vessels including more info on most of the ships from the examples section (so it would have been really convenient if that was the first thing I found!). You can get a downloadable version here. Developments of Note lists a bunch of goo ships starting on page 10 and Sources for Vessel Plans on page 71 are especially useful but it’s all cool stuff. **[[https://issuu.com/international_windship_association/docs/iwsa_-_small_vessel_publication|The IWSA Small Windships Publication]]** has tons of info on the sub-500GT range of smaller vessels including more info on most of the ships from the examples section (so it would have been really convenient if that was the first thing I found!).

-==== Whale Safety ====+=== Whale Safety ===
  
 Whales are sometimes hit by ships (they sleep just below the surface and don’t know where human shipping lanes are). Some hulls are more dangerous to them than others. Ships with steep, sharp prows and [[https://en.wikipedia.org/wiki/Bulbous_bow|bulbous bows]] are especially dangerous for whales. If you search for ship hulls and whale safety, you’ll find an unfortunate number of photographs of dead whales draped over those bulbs. Whales are sometimes hit by ships (they sleep just below the surface and don’t know where human shipping lanes are).

 There are also ongoing attempts to map our whale activity and to ensure that human crews are both aware of their presence and actually making efforts to avoid them, but if you’re looking for visuals this might be worth considering. There are also ongoing attempts to map our whale activity and to ensure that human crews are both aware of their presence and actually making efforts to avoid them, but if you’re looking for visuals this might be worth considering.
