It's surprising how much s small Solent chop can slow you down, and the ergonomics of a tiller-steered SIB are pretty lousy which makes it hard work too.
In anything but a flat calm I've found that a 10 knot average is more realistic for a SIB. I've done Portsmouth to Cowes a few times, and it's about an hour. Round the Island is equivalent to three return trips.
St Catherines and the Needles could slow you down a lot too. Even on an otherwise good day
I'm not suggesting that going round would be a bad idea, but neither should anyone underestimate it.
