My 40' IOR has the same hull
as the 40' Swan if that says anything. And some of the sisters to mine are built for offshore
The problems I see with the IOR is when cresting a wave they can be a little squirrely and heaven forbid if one were to slide backwards trying to crest a wave with just a tiller. Even backing into a slip could catch one off guard and pin you to the rail.
Personally I feel the the large rudders are actually part of the COE, a bit of an extension of the keel
. On a closehaul I use to get a lot of weather helm
running a 150% genoa
and the old main of 13'. After a eyeballing the hull on the hard
for a long while it seemed the sail plan was just too much forward. The COE looked like is was more under the mainsail
then the whole system.
So I took a risk and put on 16' of mainsail
and a 135% genoa
. Now on a closehaul I can let go of the wheel
and it sails
itself, so that proved my theory IMO. It even points higher now but that may be due to the new sails
For their waterline they are fast. They exceed the formula. Sitting dead in the water
the waterline looks like and eye. Healed over it's still about the same except the tail end is rounded.
IOR's have a lot of positive buoyancy for and aft. It keeps them moving when breaking a wave or with following seas but bad when they hit you on an aft quarter, time for the foulies.
Mine, an old racer
, could use some more keel
weight. They relied on a 4-6 man crew to level them out (rail meat).
In the chop mine gets tossed around a bit but it sure can surf the waves. I keep a drogue
on board for offshore
They have very little bilge
so if your getting water
in, you'll know it fairly soon.
They do have deep keels so if gunk holing one has to be very aware of the depth
. Mine's a bit old and not too pretty so I've been thinking of renaming it "The Ugly Duckling" (because it's not a Swan) but I'm happy with it and will probably keep it the rest of my life, unless I come into a large amout of money
The first picture is before the change in sail plan...................._/)
