Carbon Fiber Rudder Stock
To follow up on John's comments about the carbon fiber rudder stock, my boat is hull 19 and came with the carbon fiber stock. The reason carbon fiber was used was to eliminate corrosion which can weaken stainless steel used in rudder stock. I think in principal, its makes sense. There are several major manufactures, other than Hunter, presently using carbon fiber for rudder stock. It's a very strong and capable alternative to stainless. The problem encounted in the carbon fiber rudders, in case of very hard grounding or collision with submerged objects, its difficult to tell from a visual inspection of the rudder whether there's damage to the internal portion of the stock. Stainless steel may bend to show evidence of impact where in the case of carbon fiber, if the impact is great enough, its won't bend but break. In cases where there has been substantial impact and the carbon fiber rudder is intact, evidence of any internal damage may hard to detect. When buying a used boat with a carbon fiber stock, this may be an issue that the buyer should be aware. This imformation was related to me by Hunter last year during detailed conversations about the rudder issue. I was planning a long trip to Mexico and wanted to be prepared. According to Hunter, the carbon fiber rudder stock was as strong or stronger than the stainless steel but because of the reasons stated above, the decision was made to go back to stainless. Whether than is actually true or not, I don't know. I'm the original owner and have been on board every mile traveled and know my rudder hasn't sustained any impact damage. Nonetheless, last year in preparation for my cruise, the boat was hauled out and the rudder dropped and inspected. It's a straight forward procedure which took about 45 minutes. The stock looked "as new" and no stress fractures were noted. I was surprised at the size of the rudder stock. It was massive. The boat yard owner, who has taken care of all my boats for the last 20 years, said the rudder was absolutely fine. The price for a new stainless 460 rudder from Hunter is about $3,000, which if you are buying a used boat and unaware of it's history, is a small price to pay for an upgrade on a $200,000 boat. I also installed the emergency back up rudder from Hunter for additional peace of mind. They sell it at their cost for $750. It's basically the same thing as the SOS emergency rudder which sells for about $2,000.
