Jeff,
I have been a Taipan sailor for only a few months. I sail my boat single handed only. I absolutely love it, it is a dream. I've never sailed a BIM so can't compare but if its a better boat than a Taipan I'd be gobsmacked. It's hard to beat perfection.
The Taipan has beautiful fair hulls and a very stiff platform. They are also a very beautiful boat to look at. The look as good as they sail.
If you want more information on Taipans (or to just drool over some photos) see my website:
