Thank you guys for your responses.

At this time I have narrowed my choice to the Sunseeker Manhattan 52', 2017+ model. It has a fuel cap of 580 US gallons (2200L) and max range of 470nm at 10 knots, and 250nm @ ~27 knots.

I don’t yet know if this can be improved with pods drives instead of shaft.

I have looked at some long range trawlers, like Bering, because it is a dream to make at least 1 oceanic voyage. But I think that idea is better saved for later... for one thing I don'e have the experience at sea so make that sort of voyage yet :0

Also, I am hoping to get this first yacht in early 30s, so the Manhattan's dazzle factor is still rather appealing

I have also given the Manhattan 66' consideration, but the added range is only up to 70nm (despite an almost double cap fuel tank), and everything else seems like it will be added hassle, from cost to maintenance, specially as an often solo captain.
