left to right, in a small boat of shallow draft. These small boats are commonly known as rowboats, canoes, dinghies, or dories. The thwart can be used as a seat, especially on a rowboat or canoe. While you probably wouldn't tie parts of a boat to the thwart, there are many boat accessories you could tie, and help prevent their loss. You could secure your waterproof or water-resistant
ditty bag, seat cushions, or dock fenders. You could tie your cooler or a bailing bucket to the thwart. If the thwart is structurally sound, you could use it to tie up to a dock cleat. You could lay your fishing rods on the thwart, or lay your oars on the thwart, if you don't have oarlocks. There are some items you probably would not tie to a thwart. An anchor and anchor line is probably too much weight for a thwart and could pull it out or even capsize the boat. A tow line also would probably exert too much pressure on a thwart and could pull it out.
A person would be able to find the definition of the word
"thwart" in a dictionary such as a Cambridge English Dictionary (be
it either hard back or online version).
There is no such thing as an "invasive koala". Koalas are not
invasive as they are native to Australia, and have not been
introduced to any other country.
Invasive means that this animal or plant is invading Australia
e.g it could be wrecking fences. Non invasive means its doing no
harm at all e.g the cow is non invasive becaause its not doing
anything wrong, its actally helping us by giving us milk!
Invasive involves cutting the body open, invading it.
Non-invasive uses existing bodily cavities to reach areas if they
can be operated on that way. In the future, nanosurgery using tiny
devices and tiny robots will make non-invasive surgery more readily
possible.
