Another childish comment from Bob? Such gratitude!

Re: Pros and cons of steel sailboats

Brent:
Chill.
Lighten up.
For someone who cruises "full time" you sure seem way too up tight.

I didn't follow all your explanation of the welding and the twist but I suspect without hands on I would not. I trust that you are correct on this. I'll just have to learn by myself. Then stand back and say, "Oh yeah, now I know what Brent was saying."

We have considered longitudinal flotation tanks as part of our amidships seat arrangement. This would give us some latitude in moving the seat for different loads. For instance, I was with the lovely Violet today and I found out she now weighs a whopping 28 lbs. not the 25 lbs. I used in my weight estimate. And she will be growing. Dad is 6'5" and Mom is 5'10".

But in terms of scantlings Brent as you must well know, it often comes down to:
What can I get?
What sheet size is that?
What alloy is that?
When can I get it?
What does it cost?

In my case the cost is not so important due to the small size of the project (not the small size of my wallet). For instance: 5086 would cost me $1 per sq. ft. 5052. For my little project this amounts to about $100. I can handle that. But these little overages can add up so ion the end you stand there looking at an $11,000 dink.

Brent, I don't care what you do. This project will waltz on by you effortlessly. You can play with it too and have some fun. Or you can continue to be irritated, defensive, annoyed and way too stressed out for someone who professes the "perfect life".

Re: Pros and cons of steel sailboats

Opposing hippocracy and lies doesn't make me any less happy. In fact I enjoy it, like shooting ducks of a fence. You guys sure make it easy.I'd be less happy if I just let them go unchallenged, allowing others to suffer the consequences of such disinformation.
5052 would work fine for your project, and being slightly softer, may reduce distortion problems.
My 7 ft 6 inch aluminium dinghy cost me $65 for the materials, in a scrapyard.

Ouch!
You sound like one very uptight and confused guy.

I tried to bring this thread back to where we could all have some fun with a metal boat. But you want to infect it with your own personal problems. That is dissapointing.

Bob
A thought for your aluminum welder, perhaps before or after bending use a rosebud
to stress relieve the aluminum? I am no master welder just a wierd thinker.

Rat:
A "rosebud"?
I'm just a guy with a computer and an imagination. In have no idea what a "rosebud" is.

If I knew, I sure as hell would not know what to do with it.
My sister's doll was called "Rosebud".
But that was a year or two ago.

My builder, Jim, Betts, you can google him. is a master with alu hulls. He has "the eye".

I'll meet with him next week and see what he has in mind. He wants a boat so now he is emotionally connected to the project. That good.

Re: Pros and cons of steel sailboats

A rosebud is like a small shower nozzel. It is for oxy acetiline and produces an ungodly
amount of heat, like unto the fires of hell.

Cool. So when does that start?

Re: Pros and cons of steel sailboats

I think that Brent is raising a very valid point in his comments about distortion of the plates. From my own experiences with welding I am very aware that distortion can be a serious problem especially for the inexperienced welder. From my limited experience I found steel reasonably forgiving. Other metals not so much....In my case about the time that I thought I was a pretty good welder I decided to weld a small SS fitting. A friend let me use his shop during lunch. After carefully shaping the parts, I spent an hour welding them together ending up with a useless pretzel. I made the parts again and went back to my friend who 10-15 min later had made a flawless weldment that just needed to be polished out.

In this case, the good news is that Bob is using a welder who understands aluminum. But it highlights the issue of amateur construction. An amateur with an aptitude for welding might be able to weld up a steel boat with reasonably thick plating, but I seriously think it is far less likely that an amateur can weld up an aluminum boat without a lot more practice and experience than would be easy to acquire as a dilettante.
