I have an Ida Sailor kick-up rudder also, and have wondered about the additional weight at the stern. I would imagine, though, that the weight gain is somewhat cancelled by it's buoyancy once the rudder is in the water. Not as much as a wood rudder for sure, but it must be lighter in the water than it is out. On Wed, Oct 21, 2015 at 11:08 PM, Thomas Buzzi <thomaspbuzzi@gmail.com> wrote:
The stock wooden one of mahogany with pintles and sliding ss rod weighed a little over 22 pounds. The IDA rudder I have made of high density plastic top and bottom with aluminum side plates for a hinge weighs in at about 60 pounds. A hugh addition to weight right at the back of the boat. Not good. I may go back to a wooden one and make it a kickup with side plates. Or redo the top half in aluminum plate. My list of winter projects is starting to grow. Tom B

Tom B,
What did the rudder weigh? Type and density of woods (different types of mahogany over the years) affect the weight and ultimate strength - my last wood rudder was little better than bad pallet lumber and warped in a few months (stored indoors)
Inquiring minds... That is why 'we' built a plastic one. No warping and mucho control over strength,weight and shape!

I have a 74 - plain wooden rudder, painted, two pintles, no sliding rod gizmo. I can weight it if you want - I assume the rudder was pretty much the same from 74 to 77?
cheers, John S.

Does anybody know how heavy the stock wooden rudder was on 17 Montgomerys built in 1977?
