G'day,

I don't think much of in hull rudders, and even less of drum rudders, but they are not too difficult to make from composites and acetal ball bearings from McMaster Carr.  You will need some turned alloy or steel (better) rings to use as moulds.  Let me know the width of the hull and I will do some drawings.

Ok, that is at least 10 times the price I am willing to pay. Anyone have any ideas on what it would take to make one (well, two, actually <grin>)? I would like to think that there would be an easy way to just build some extra rudders if you do hit something and pull out the old one (or push it down through) and replace it with a new one and (maybe) repair the old one at your leisure.

Is this the system that Rapscallion was going to use? I remember his having in-hull retractable rudders, but I don't remember a mention of a drum, so it did not seem that they could steer while retracted, which turned me off.

Gardener,

I got an answer in 2008 from Paul Amon for the inboard rudder:

 

Each unit as installed on a Melges 32 would be around 6900usd with hard anodized bearing, rudder, tiller, housing.

 

Quite expensive, no solution for us.

 

Cheerio
