36" SilverFox Catamaran

[golfito]

In FB, there were some photos of a renewed and reinforced hull silver fox. But it did not last long, it seems to me.

It was all good till the customs tax. I emailed them their supplier is still building them the hulls.

So you Yanks are finally getting charged customs tax? I thought that you were all exempt from that up till now.

For us in the USA $50 for hull 60 to ship, $110 total.

Missed this.

Yanks huh! I’ll take it as a compliment since we won the war.

They do not look bad!
It is not mine. But I would like to achieve something like that.

Not really sure why they would set the motors off at that angle and then need to bend the stuffing tube. It I were to do twins I would want the motors and stuffing tube straight.

Give it time Ray, if not built in USA ....

Theory is that it is better to have a bend in the flex. A straight flex can vibrate and oscillate.

Okay but normally the bend would be in the flex to align motor to stuffing tube. This way seems like it would have two bends for alignment. To me seems a little weird looking, but I am no boat building expert

The bend carries thru the stuffing tube. One must bend the tube to match the natural bend of the flex. Tricky? Tedious? YUP!!! but it is what has to be done.

I just built a cat. I can assure you that this point was what caused me the most problems. And I'm left with a strange curve, like the one in that photo above.
In my case it was because of trying to put the engine very late. There was no possible solution other than to increase the doubles.

There have been a few of the German fellas and now our friend Kent( CustomCF Parts) that have run very straight flex setups with the only bend being at the transom where the drive bolts thru. I think they can get away with it in larger hulls (54+”) so that the motors are not so necessarily close to the transom. There is nothing wrong with the bend as long as the flex goes straight into the drive. This will help with bearing/bushing wear.

If I admire Kent's works. His photographs are addictive.

I am learning with my boat, I am trying to do what I can by my means. It is the first, I will try a second construction with this silverfox.
I know he curved a lot. But there is not so much friction. I think it will work. It also will not be a racing boat.

As long as the bent tube matches the bend of the flex there should not be much friction. As I started I would end up shimming the motor and such to get a decent alignment.
You guys are on a good start, play with a couple cheap hulls to learn skills. You don’t feel so bad if you feel the need to redo stuff because it doesn’t.

I made the mistake of first adhering the motor supports and then forming the tube. Next will be the whole tube and the flex and then it will be attached.

If you buy these boats with that idea. To be able to work them and modify them.
