When I purchased my boat awhile back, I got an extra set of rudders. The previous owner was as clueless as I am about them. They are white and have the name Raditch Speedblades on them. They appear to be made of plastic. My searches have turned up nothing on them so far. Is anyone familiar with this brand of rudder?

Thanks,
Dave W

Do they fit your Hobie? what do the hole patterns look like.

You said they appear plastic, is there any way to tell what the interior of the rudder looks like. Maybe looking into the drill holes.

They seem like racing rudders, are your other rudders better? Is that why your don't use Raditch

The spare set of rudders have the holes filled (epoxy?). However, they are identical to the set that is on my H14 which are also Raditch Speedblades. After looking more closely at the ones on the boat I noticed the bottom tips where there is some wear is a darker brown-grey color indicating the white finish does not go all the way through. Would that indicate they might be fiberglass? Thanks.

I've got a pair of "Switchblades" that have some mystery substrate, similar to what you've described. One, of the pair, had obviously dropped down when trailering and worn through exposing this material. I have no clue what it is but that particular rudder weighs about twice the undamaged one, even after being left exposed to dry out for literally years.

To answer your question, more than likely the outer layer is glass and gelcoat. Chip away at the damaged area in search of fibers.

I've got a pair of those rudders. They were made by Rick Raditch from Tampa back in the early 80's. We set up next to him at the Midwinter's East In St. Augustine. He was a buddy of Bob Curry when he was stationed at Mc Dill Airbase in Tampa.

When I saw them I speculated that they were made of Kevlar or carbon and got a positive response.

Thanks jkkartz. Any idea what a used pair of these might be worth? I am thinking about selling my spare set since they are just collecting dust.

How much is a set of EPO's worth?

That is probably the closest comp.
