We have chartered both and I prefered the Lagoon - which I did not think would be the case. I thought it was more spacious, more comfortable and in my experience performance was pretty much equal between the two. We actually had a higher top speed on the Lagoon, but the conditions were pretty perfect - 20 knots off the beam with little swell and dolphins off our bow(s). Man, I am counting the days until we can get back down to the islands - would just be nice to know how high I have to count.
