AOR Replacement & the Joint Support Ship (Merged Threads)

That is a big ole boat. How big is it in the grand scale of things compared to other ships of its role?

Depends on how broad you define its role. Using the NATO definition here:

Oiler Replenishment (Naval) (AOR). Ship of at least 140 metres capable of providing rapid replenishment of POL (petrol, oil, lubricants) and solid store products.

Protecteur is about 174m long and ~20000 tonnes. This is right in the ballpark for a lot of allied navy AOR's, which are usually between 18'000 and 26'000 tonnes.

I have hung around enough sailors to confidently state that it's a big ole ship, not a big ole boat.

Just turning a phrase haha. I'm aware it's a ship.

Thanks! So she'll be very valuable as part of NATO battlegroups (or whatever the term is in Water Speak) since she can plug and play as an equivalent with allied ships?

Yes.

And it’s Task Group.

So this is my biggest pet peave. There is an engineering difference and a specific definition here.

This is why submarines are always called boats. Because their centre of gravity is below their freeboard.

So a kayak is a ship... interesting.

only if you spend 30 bucks to break a bottle of bubbly over the prow whilst announcing its name to the world. Otherwise, it is just a kayak

Nope. Unloaded a kayaks centre of gravity is below its freeboard. Freeboard is the first "deck" (or top of the gunnels) above the waterline. And as a kayak has only one deck and the rest of the kayak is below that deck its a boat.

The turning part is a function of there the centre of gravity is and not critical to the definition. If you start playing with the propulsion forces and loading you can get different turning results. Wind loading on sails for example.
