I can't see a problem with that but I do know some 316 valves have non stainless handles and nuts.

Brass could be a problem, sure you don't mean bronze?

No way would I use brass, too rich with zinc and disintegrates quickly. Bronze is what should be used.
Those stainless valves would be OK if their heritage can be reliably determined.

5 years ago I replaced all sea cocks on my Martzcraft 35. They look just like that one in the photo. All of their handles corroded into dust. The handles were some kind of aluminium. Now on one the shaft the handles connect to has broken as well so even the shifter doesn't work.

Bronze skin fittings with bronze sea cocks or stainless skin fittings with stainless sea cocks. Do not mix the metals.

I have all bronze.

Trudesign skin fitting are the only way to go. I have just replaced all my skin fittings and valves. They cost a few dollars but no metal fatigue is a massive bonus.

AH that's nice, we'd hate to see you on the news after the brass ones dissolved in a year or two!

They are great but the Forspar ones from Deck Hardware are just as good to, another option!

Plastic composite ticks all the boxes
unless 100% sure of bronze/Ss quality
and how does a layman ensure that?

Around 2000 a Top Hat leaving the Camden Haven Inlet got pounded by the bar [went out the wrong official way!] and some gear came loose and sheared off one of his PLASTIC sea cocks.

He almost sunk but due to quick work on his part and Marine Rescue he made a full recovery.

Replaced all his seacocks with bronze ones!

If it sheared through water force then it was poor quality. Look at manufacturers listed above for high quality survey standards plastic ones.
It may have sheared due to a loose object hitting it and that's the skippers fault, not the fitting!
The issue with bronze or SS is that the quality of the metals used is cheap and unknown due to the dedicated marine market being tiny compared to land based uses where corrosion is not as much of a factor.

I know of a 48ft cat who brought the best quality SS skin fittings and valves when boat was built a few years back.
After first Pacific cruise, they were corroded to hell and all were replaced with Forespar plastic!!
Boats now done another 25,000 miles with no issues.

No plastic, uh uh no way jos'e, bronze only below waterline, my brother in laws Quintrex had a plastic scupper that let go out on the shelf 12 mile of Bermagui, lucky he had a bilge pump coz hes about as handy as a handbrake in a speedboat. He now carrys wood plugs and a rubber mallet, doubt he could use either lol

Well there is so much wrong with that before you blame the plastic!!

Firstly a scupper should be installed above the waterline at rest, if it wasn't then that's shocking boat design.

Secondly, Quintrex (and most production ally builders) would use the cheapest they could get their hands on, see above comments on quality brands

And finally, you have no option on a pressed ally boat apart from ally, and not many fittings available in ally!!

Do not use brass, do not use stainless. Brass lasts about 5 years then gives up;- look at the correspondence on European sail boats, there's plenty of discussion. Stainless corrodes and breaks.

Us the fibre reinforced plastic (Trudesign, from NZ) its what all the sailboats are converting to.

I am pretty sure he means a Bung. Which will pretty much always sit below the waterline. Unless Great Aunty Alice is sitting on the Bow.

Well If he means a bung, it was either badly installed, badly screwed in or missing the o'ring (bad maintenance)
Seriously I have been in the chandlery game for 20 years and NEVER heard of a bung letting go!!
