Re: alu sailboat buliding

Not to be rude, but those welds look questionable.

Re: alu sailboat buliding

The weld beads under the two wooden poles look like they aren't complete.

Re: alu sailboat buliding

How did the test go?

This was no the plan. I hoped the weight will not be more than 50 kg so 2 people could get it on deck.

So now i wonder about making another one.. More or less same size but with lighter material.

why didnt you just make rounded aluminum shields for the top pontoons of the rubber one? to prevent puncture from tusks..

Re: alu sailboat buliding

Maybe use a davit or such, so one person can deck it.

Re: alu sailboat buliding

Looked like some pretty good welding to me

Re: alu sailboat buliding

I couldn't find some of those weld pics when y'all were trying to repair engine mounts. If you're doin' welds for others, I hope you've upped your game since then.

Maybe that was another thread. If it was........my bad.

Not excactly that rig, but i was looking into chinese junk rig for a long time. But in end we ended up with traditional gaff rig setup.

Re: alu sailboat buliding

I've bought and refurbished several fiberglass sailboats over the years ranging from an 18 foot lake racing boat to a 32 foot Coranado center cockpit sloop. You spend an extraordinary amount of time in those projects and I am sure that's more than doubled when you do a build from scratch. I haven't done a steel or aluminum hull yet but those have always been higher on my preference list over fiberglass due to the durability factor.

I talked with a guy who had a 50 foot steel hull Ketch Rig that he was selling (price was just a tad out of my budget). He told about how it got washed up onto the rocks during a hurricane in the Caribbean. They basically dragged it back into the water and then sailed to Tobago to have it hauled out and inspected. No major repairs other than cleaning and repainting the hull and replacement of 2 thru hulls that were showing minor leaks. This is why I always had metal hull as a preferred material. A fiberglass boat would have destroyed in this same situation.

I'm still dreaming about retiring aboard my own 36-50 foot steel or aluminum hulled boat and just seeing where the wind takes me. Best of luck on your build project and do keep posting updates and photos as it progresses.

Re: alu sailboat buliding

The welding business is doing good. We never had intention on making money in industrial world since we are by heart farmers, but its more money into making money welding on other boats than making honey but still interesting. Strangly its not many competitors welding in aluminum in Oslo area so we can charge around 100-120 dollar an hour.
Honey sells for 15 USD per lbs. Plan is to process around 4 tonns of honey at full capacity (that is 100 hives) in 2 years. Not sure if possible to manage to get rid of that much to consumer though.
Long term plan is having this boat roam the seven seas forever with money generating from a land based income.
We learned the had way that even if the wind is free,its kind of expensive roaming around the seven seas.

We also formalize our skills and will take exams in IWE/IWT.. (taking course now)

Matter of fact, first exam today.

Re: alu sailboat buliding

Has not been very active here lately. But boat is doing good.
We are running our own welding shop on the side also to finance the sailing part. (plus a farm ofcourse)

Here is a question for you guys out there
We have a sheet metal brake in cast iron with a crack. What is suggested way of trying to weld this up?

Re: alu sailboat buliding

Very cool project, I re-read this every few years.

What are your travel destinations for the rest of this summer? Any repairs or refits aside from the sail clips?

Re: alu sailboat buliding

Do ya mean to say it costs 4000 pounds?

Or have ya run 4000# thru it?

Re: alu sailboat buliding

Well, if anyone can do it, I'm betting on you. Anyway, $30? Ouch. Have you looked at wichard hanks? Since they're stainless, maybe they'll wear better for you?
