Well if you raise the issue and document that fact then if there is a problem at least you can go back to them to fix it.

It happens to be in Italy right now, so tomorrow it will be the first issue to discuss with the project manager

Make sure you put in a very strong specification for isolation of stainless steel fasteners in a carbon structure.

If you think aluminum and stainless react badly, you should see carbon fiber and stainless. Looks like a lot of fasteners will be screwed into that structure.

Just eyeballing the thing, I was wondering about that tubing myself. For appearance sake, if not strength, I would be tempted to replace it with a short length of mast from a sailboat? So the dimensions would be much, much larger than just 2 inches. Plus the sailboat mast material would have a very pleasing oval shape to it. Of course all those brackets would need to be redrawn ...

two coatings of epoxy primer have been applied straight on the resin and then epoxy filler (we are in the middle of fairing tasks)

Welcome to geriatric status Comship. You're officially a centurion now!

All that needs is a fairy on the top (joke)
IMO, theres too much weight, too high up on too small a footprint...I'd be concerned with the continual leverage this arrangement will transmit to the mounting points on the hoop top surface. Scale wise, those vertical tubes look more like 3" dia, but I'd go for 4" dia low down and try to spread the feet out wider. You may get quite a bit of vibration through this arrangement too, resulting in a pronounced wobbling of the very top end. It just looks very tall and skinny for the weight its carrying.

The mast shall be constructed by 3" tube. Many thanks for your kind reccomendations

[KCook]

Err, perhaps that drawing is just not filled out yet? But as it appears now, I'd say the concern from CODOG still stands - "too small a footprint".

Looks like a very different mast. I would once again be checking over the specs on all equipment to ensure you do not have issues resulting from proximity to other equipment.

[CODOG]

The last pictures are obviously not to scale and rather pictorial...totally different arrgt from the original. So, if this is the revised arrgt, its almost impossible to comment as to the aesthetic or structural aspect due to the sketchiness of it all ? I'd now be worried by the practicality of cable entries and servicing of the various items, with the aparent lack of space between each item and the extremely thin mounting platforms for each item...access to the underside of the domes, hingeing the radar covers back etc etc (radar antennas hitting the structure) Please tell me this isnt a build drawing from the yard ?

[comship]

I am sorry indeed its a different mast, I have uploaded wrong pics

[KCook]

No harm. If anything, that is a relief to hear!
