They also have 800 amp hours of lithium batteries on Delos. And other boats I've followed have even more battery power. And, they live full time on the boat.
I was skeptical about induction on sailboats, at the beginning. Worried that the magnetic field would mess with expensive electronics. And, also worried about non-gimballed, slippery ceramic cooktop underway. Wondered about the amp hours consumed.
Several boats I've watched have added a slim silicon sheet for non-skid on the cooktop. Some have added a fiddle (railing), and some have re-used the gimbal of their old propane stove for a new electric/induction stove.
None of these are important in Ollies, where we only use the stove when stationary, of course. And ah consumption, as reported, has been not as high as I would have expected.
I could definitely see a good induction cooktop in an Ollie that had a way to power it. I love cooking with induction. Fast, clean, minimal extra heat, no fumes, etc.
