Denise, the debate here seems to be whether IP's are "true bluewater boats".
I'm a bay sailor with no aspirations to cross oceans; the IP's I've been on have been very nice boats, roomy and comfortable below and seemingly well made and solid.
The IP owners I've talked to all seem to be happy with their boats. I have noticed sailing near them on the bay that it takes a bit of wind to get them moving though. They're not light air boats, but I'd imagine that would mean a more comfortable motion.
BTW, how is your boat doing on her mooring? I was in Trenton today and was shocked at how high the Delaware was running with all this rain. There must be some interesting stuff washing down the river
