EDF.com Exclusive

I did some digging and here's some specs about the yacht that Ellen and Portia Are on (I don't know what it doesn't have)

It has a salon, dining room, bar, grand piano, new flat screen TV, jacuzzi, personal chef, spiral staircase, “glass bottom” underwater viewing table, King size bed and en-suite bathroom featuring a large shower with rain bath and multiple jets, sleeping quarters for 12, 2 Kawasaki  waverunners, 2 2-man Kayaks, Snorkeling gear, Fishing gear, crew of nine and is 142.2ft in length

And even a "hotel-style safe is mounted in the room" so Portia has somewhere to keep her new $60,000 ring that Ellen gave her.

And did I forget to mention that it only cost $175,000 per week and it's currently for sale for a reported $12.500.000 so maybe if Ellen likes it enough she'll buy it.
