I, as a sailcat owner, would be surprised/angry if my charter company chartered you my boat with no sail experience .

I would suggest going with powercat, UNLESS one or more of your crew had a genuine interest in sailing and did sail course prior to then.

The horsepower is sufficient. Mine has 57 hp x 2 and is only 42 ft.

Please let us know who would charge a cancellation fee after juts a few days without vetting the crew experience.
