we own 1979 GulfStar
37 ( NO SNEARS AND CHUCKLES) i know alot of people think they are less than a good boat, but they were the innovators of most of the tech used today, back in the 70s. anyway they used 1/8th inch aluminum
backers under the stanctions about twice the diameter as the base. i know i'm lucky as they have never been rebedded in 29 yrs and are now just starting to show signs of leaking. i believe they used alm. because of the flex versus stainless steel
. anyway the prob. with stainless is that on the under sidetowards the deck
where air cannot get to (ie sealant
gets to it and goes undetected crevice corrosion
will start and not be seen until the S.S. bleeds orv it fails when pressure is puit on a stanction at the wrong time.
