Whenever I have looked into it I have come to the same conclusion: if your boat already has a functioning diesel it doesn't make a lot of sense. If you are ripping out a dead diesel it would be a fun exercise. But unfortunately the second hand boat market just isn't sophisticated enough so at resale time you will be hammered. No problem if your boat represents a small enough fraction of your net worth that you don't care but that not my case.
Is it possible to cruise with an electric drive? Absolutely and there are people who are doing it now.

It would only work if you didn't have to get to work on Monday. i.e. you'd need to be happy / confident sailing an engineless boat. In effect the storage capacity for electric drive is only useful for getting in and out of marina's, or other key navigational tasks such as no wind and a strong tide around a hazard.
Without mains power, you just don't have the square area for solar panels, and you can't store enough power for the average size boat to get any substantial range (yet).

The idea is fun, but it is still terribly expensive and the big issue is that because you will be using a large amount of current capacity, you need a huge source to put the power back into the Bank. So far, no one has been able to safely harvest a lightening bolt, so we are stuck with a generator to get the current back. If you have a genset, you may as well have a diesel engine.

If you are starting with an engine less boat costs aren't a lot different from putting in a diesel, but hard to make apples for apples comparison. Hardly matters though- if you like the idea do it.

Fish is correct I am aware of a few early adopters who have since come back and purchased a conventional diesel, range issues being the thing, cool if your cruising is town to Issy bay or Motuihie but unless you have a significant solar array and no timetable issues we are not there yet, a rum racer may be the ideal boat.
