Rudder setting maxed out but rake not acceptable

yelkenli1 wrote: I might know the answer to this question but let me know your thoughts. I have an 07 H16, which used to be in a rental fleet, so not sure of the age of any of the parts. I noticed the port and starboard tacks do not have the same weather helm. Looking at the pictures of the rudders, there are clear differences.

Ted, I know you will get some input on your rudders. This is an excellent example of how to ask a question giving the information and pictures needed to see the problem. Good Job.

Only one thing, it appeared that when you got the image url's from your album that you used the thumbnails instead of the larger size pictures. That caused the previews here on the thread to be blurry because they were actually enlargements of smaller thumbnails instead of reductions of the larger pictures, if that makes any sense.

I've edited your post to include the larger pictures.

Fill and redrill the holes(you may only have to do one rudder). Find someone knowledgeable with a H16 to get the correct hole location.

I remember reading somewhere that Hobie has a template available, it has the H16 bolt hole locations, I'm not sure if it it a paper template but how else would they be able to ship it. Otherwise you would have to make your own template by finding another H16 owner with original rudders and tracing a template off that to compare with yours. From your excellent description though, it does sound like the bolt holes are incorrect.

The template and drilling instructions are available as a PDF in the support section of the Hobiecat.com site.

There are dimensions printed on the template to make sure it is to scale. When I printed it just now the dimension that should be 9.375 " (9 3/8 inches) measured out to 9 1/8 ", but then I remembered that the default print setting is "fit to paper". Changing that to print actual size made the dimensions match within 1/64".

Use the template to find out if your blades are drilled for the kind of castings you have. There are different hole locations for adjustable and non-adjustable castings.

Hobie 16 rudders have 2 different hole locations. One for non adjustable upper castings, and a slightly different one for adjustable upper castings. It sounds like you have one of each on your boat, if a rudder was replaced this could easily happen. I have the medal template which I purchaed from my local Hobie dealer and it has all the locations for the different Hobies. Very glad I purchased it. Just a hint, when I have to fill a hole to redrill (as the holes are very close) I use a fiberglass rudder pin to fill the old hole. Drive it in cut of flush, works great.

Thanks all for the replies and links. I will take these off and fill and redrill. That has to be the problem. If not, the second candidate is the port lower casting as that has a different finish and has already required one repair job.

Hullflyer, are these rudder pins what hold the lower casting to the hull gudgeons? My pins look to be some type of metal (technical term learned at summer camp a al 'some kind of meat')

I understand the job would be to dope these up with resin/epoxy, press them in, and let them set. Then mark the new hole location and re-drill? Any recommendations on drill bit type or technique?

Thanks,

Do the best you can to keep the epoxy from spilling out of the hole. When I did this once the epoxy came out and the puddle dried into a sanding nightmare.

Mike, there are 3 types of rudder pins, SS, aluminum and fiberglass, just get/order/buy/steal a fiberglass pin and use that to plug the hole. Then use epoxy to finish off if necessary.... 😀

But don't be tempted to use a fiberglass rudder pins as .... rudder pins.

If you do you could be sailing along, hit an obstruction with both rudders, have both pins break off, have the force of the water pull the tiller out of your hand, and lose your entire rudder system and tiller stick to the deep blue. Could happen.

Easy way to fill holes. Tape a piece of wax paper(dust tape work well) over the hole on one side. Lay on flat surface and fill. Epoxy and micro ballons.

Question for everyone that has re-drilled a lot of different rudder blades.

Does it matter which material your blades are made out of? Can you always use the thickened epoxy whether the blades are basic plastic, lexan, fiberglass, or carbon?

This issue comes up a lot, it would be great to have a step by step technical help gallery about the process.

Scary to drill into rudders, when you buy brand new ones they don't come drilled so you have to drill into brand new blades.

When I was in High School I worked in a sporting goods store where we sold bowling balls, always stressed about drilling holes in a brand new ball. 😡

Measure twice(maybe three times), Drill once. I recommed a drill press with the blades being level. Drill the hole out of square and you will be doing it again. (Don't ask me how I know.)

Yeah Damon you can always 'fix' the holes On the Lexan blades there is really no need as the blade is solid UNLESS the new hole needs to share the space of the old hole
