Used a 470W remoska standard size many times on our hire boats. The first thing we check when hiring a boat is has it got 240V and how big is the inverter (1kVA preferred). Prefer to use while we cruise to save running the engine / draining the batteries in the evening. Even tho it has a stand, we use non slip silicon mats underneath to protect surfaces. Had good results with Spanish omelettes, risotto, garlic bread, sausages/toad in the hole, sausage rolls, fruit cakes, jacket spuds, tarte tatin, blackberry and apple pies/crumbles, rice puddings. Easy washing up too. Also bought a cheaper Koolatron version on eBay (available from Amazon I think) with dial for temperature control.
