Ericka, as you see I had already written a short report on my trip on the Silolona (which has been quoted by Kagehitokiri). I confirm that the sea has never been an issue during my stay, with the exception of only a short part of the trip from Moyo to Komodo where the sea was a little bit more exposed to winds. For the rest of the trip we virtually saw no waives at all (see my pictures in the link below to have an idea).
Feel free to ask for more information.
Best regards
