We bought this for a cruise round Cornwall in June. Needless to say it didn't get used but on returning home to Neyland Marina the weather was hot and sunny. The parasol covered the cockpit of our Bavaria 34 (1999) very well and we could sit in the shade. The boom had to be made a bit higher with the topping lift to accommodate it. Having put it up once and got the length of the lines right it will be much quicker next time. Obviously this is not like a Bimini, the box clearly states "only use on idle boats"!
