Art, I'll try your plumb bob thingy....man, you must have been bored!
Try to let a feather weight plumb the bob as if you lean over the side and cause a list...the bob measurements might be "blob" measurements....

Not that I am suggesting anything.....

All the weight she lost was all the attractive accessories above her waist. She retained her big butt.

Early in my flight inspection career, we were conducting an orbit around a Navy TACAN transmitter on the south end of San Clemente Island. There's a firing range on that end that often had Navy ships lobbing shells toward the shoreline. We were at about 2000 ft above an Iowa Class battleship (perhaps the New Jersey or the Missouri) when they started firing the big guns at the island. We could hear and feel the concussions of the guns firing inside a Rockwell Saberliner 80, a pressurized business jet not known for being quiet. Obviously there was a breakdown in coordination with them firing while we were still operating in the area. Not the last time something like that happened to me on the job.

We're talking pre- and post-retirement!

Man - I was! And, anyway, isn't it always good to know your gal's waist size too!

In all due respect, to everyone here... just being on most threads = a form of boredom!

Of course, on this very important thread... no chance of being bored here

I have no idea what my waterline beam even is.
Neither do I, but it makes me ponder the difference between a vessel with a relatively flat stern vs. something purposely rounded or double-ended. Is the WL of a fat round boat actually the radius of it's footprint on the water, and because of that, could the WL of something like a fat double ender actually be greater than it's overall length.

was pondering that myself...but for definitions...lol doesn't follow the boot stripe...

I think there is a term immersed waterline that varies with hull shape and heel , then there is just variables to the into account stern shape.

I thought I read awhile back that the 1.4 time the square root of the waterline was just an average. The shape of the transom changed that number by a few tenths up or down.

Just fer S&G... not that I'm suggesting any suggestion is ever made ~

While trying to have boat sit vertically plumb with no one aboard (pets over 16 oz. included): At dock... on one side of boat, place the bob (almost to touch water) on string hanging off edge at widest beam area of boat... Then measure at waterline to point on the bob. Take bob to other side and hang similarly. Then again get off boat so it vertically equalizes same as a few minutes ago. Measure same as you did on first side. Take combined measurement and subtract from deck line's broadest beam. Note: no breeze and no wakes/waves allowed.

Voila - you will know your baby-boat's true waste size!! Yeah Baby! I learn all my larger boats' waste size during first couple months ownership... Call me weird if you like. I call it loving care; i.e., getting to know you!

PS: I also always make sure my boat-babies have rubber reverse flow aprons on each exhaust pipe out of hull. So her power plants don't ever need to be (burped) drained before starting.

Probably not , the gun barrels are recycled as bombs to penetrate very hardened underground bunkers.

As in the term Alan Greenspan coined... "Creative Destruction"... this time in more ways than one!
