My understanding is that most masts use grade 6061-T6 aluminum. This grade can be welded but that "T6" at the end means that the aluminum has a heat treatment process done to it after it has been extruded. When you weld it, the heat treatment is removed (annealed) for a short distance from the weld in both directions. This means that the metal will not have the same springiness. When it is loaded, it will stretch and not spring back to the original place. Think if a paper clip versus a coil spring.
Welding is best done at points of support and will not be as stiff as the unwielded section. That is why the sleeve is needed inside the tube. And yes, I am a structural engineer.
I am working with a local friend to find someone that I as owner and he as professional both agree is up to the task

Ok so I'd like advice guys. And this is not. Today thing but a wait until after repairs are made.

I want to relocate the steering. For easier and more comfortable steering. The 1st pic shows where it is and the second shows where I'd like it to be. Since there is already a stand there I figure it shouldn't be to hard. Even if I pay someone to do it

While @Hayden Watson is correct, strength loss through welding on the 6061 alloys it's not so critical. I quote from ASM handbook on Aluminum volume III Fabrication and Finishing, page 414 - "Repair welding of the moderate-strenght heat treatable alloys, such as 6061, is easy and has little detrimental effect on properties."

I think it will be much more difficult to do than you expect. The mechanism you will find inside that box behind your wheel is not as simple as just moving the steering wheel.

I agree. But feel it must be done for better visibility as well as safety under power.

I would get the boat motoring and sailing before I moved the wheel. I think that will be a fairly involved move if done properly. If you have to pay for others to do it, I don't think it will be cheap. You may find that it's a fine location where it is. I would be more inclined to get that other stuff out of the companionway. The current wheel location seems to leave the cockpit fairly open.

I used my boat for about 2 years before I started changing anything significant. Took that long to get a feel for what needed changing.

But, your boat, your choice.

Thank you. And I agree. It is something I want done only after the repairs. But it is not a easy job. So I figure get advice now and save it for later rather then trying to do the job and gather info at the same time

It would be a lot easier to move if you change from mechanical to hydraulic steering.

Pop the cover off and shoot a picture of the steering setup. Hard to give meaningful input without knowing how it's built.

Linkage/fab-wise this is probably spot on. But, if I went hydraulic, I'd want a readily available tiller backup.

For sure. My CT37 had an arrangement like that and changed to hydraulic. A cover plate gave access to the rudder post for a tiller.

I will get pics of it tomorrow.

I do agree with the need for a back up. I think this boat has one. But I will double check tomorrow.

The location and design is certainly old school. It is a sit beside and steer idea. From the side location you should have reasonable sight lines while sailing.

Issue with the new location is that the binnacle will be right in front of the engine dashboard. Hard to read the gauges while standing at the helm. Or do you thing you’ll be moving them as well.

You’ll want to consider your moving about the cockpit to manage the sails. I’m guessing, because you really need to see the physical space and consider crew movement, but it appears the new steering position will conflict with managing the sails tacking.

The hydraulic suggestion is a good one by Michael.

I need to replace Tue gauges anyway as plastic faces are unreadable. So a relocation is planed as is relocation of the compass mount location

That is somewhat in agreement with what I meant. There is very little reduction in shear strength so if the weld is at a point of support no problem (top/bottom) At other points where the moment is greatest, it is more problematic. The loss of temper is limited to only an inch or so but that is replace with the sleeves inside.

Need help to find a wind generator. 200 or less. I found some on Amazon. 400w for $150 500w for $200. Anyone tried them. I figure wind and solar should keep my batteries charged up

I think I may be missing about 16inch of my mast. Builder recommended repairing what I have. Then measure what is missing. Then at that to the top. Then reattach the mast head. Sounds doable as I believe there would be less stress at the top. Any recommendations?

I am not sure if I am missing any but better to plan ahead

Builder have sail plan drawings from the boat designer?
You can always add a bit to the mast then see if the sail plan is too much... (Sort of experimentation to failure). Look at the designed sail plan. Or ask a designer to develop a sail plan if one was never done.

Working from design drawings saves the expense of buying/modifying sails to see if they will work. Of course in the golden age of sails, captains would conceive of adding a bit of mast or rig another strip of cloth to see if they could get a little more speed out of their boat.
