Wow Simon that is some beautiful metal working job! Have you operated your drivetrain out of the water to check for vibration? But I guess it should be alright, everything looks stiff and strong.
Is your strut made from one piece aluminum, worked using just files and a drill? It looks great, as if it were a machined part.
Have you checked the C.G. position? You might need to place the batteries to the extreme front (even touching the front sponson mounting tube!) to get this right. so maybe you could do a trial component and battery fit to check it out, I couldn't believe I had to push my cells so far to the front (in fact bury them in the hull
)
The strut is two pieces. Tube bonded to flat bar with epoxy to smooth the join line. It is strong.
I have done a dry run and there is minimal vibration, not none but not enough to worry me.
CoG is a bit of an issue at the moment and you are right, i do have to post the battery pack all the way under the foredeck up to the forward sponson tube.
It now has a coat of filler/primer on it and I will start on the topcoat tomorrow, we are all going out to the hardware store to choose the paint colour.
I just want this thing to get up on three ponts as intended and to spit a nice big rooster tail in the process.
No fliping
No rolling
No sinking [X(]
Remember my design brief from the start.

I am after a rigger primarily as a straight line rooster tail spitting speed machine to honk down the pond.
