Yes, I could draw you a new blade, but it wouldn't contain any plywood
. Inert or relatively so materials are best for appendages. Plywood
is an exceptionally poor choice, not because of rot
, but because of "rolling shear" of the wood fibers, within the panel, which can cause sudden and usually catastrophic panel failure.
My data base will likely have the construction details of your yacht, including "production run" changes, which this could easily be and would be a common type of model run change.
Yes, there are several "issues" with the current rudder
blade, all attrubuting to poor preformance, excessive resistance, vibration, noise
, cavitation, excessive shaft strain, etc.
Contact me by email
(click on my name) with the make, model and year of your boat and the hull
number, which should be carved into one of the major structural elements, such as a bulkhead, deck
, etc. I ask because there seems to be some confusion (on my part) of the actual boat (Hinterhoeller-28 or HR-28) and the year built, as my record
show 1967 as the first year of production. Don't panic, it's not uncommon for boats to be mis-labeled on a title or called the wrong thing on a registration
. Before HIN's were in wide spread use this was a very common issue. We'll figure out what she is too.
