Zinc chromate primer is amazing stuff. I repainted my edson pedestal using the zinc chromate primer after a good wire wheel and solvent cleaning; a decent krylon spray paint and it is going 5 years strong now no sign of any issues. Same with a radar mast I fabricated a year or two earlier.
I have used a Walker Bay 8 extensively as my primary dingy for the last 10 years in Hawaii and the Pacific coast from San Diego to Seward Alaska. It has been fitted with the tubes recently to compensate for the addition of an outboard motor and a growing boy. My wife swamped the thing in Hawaii, but sailing in 20 knot winds and before we added the tubes. Overall it is mostly safe and very durable. No holes in the hull and almost all rocky beach landings. Note that the max persons is two at 360 lbs, so basically this means two very fit and trim adults or an adult and a kid. Two average male adults in the USA would easily exceed it's ratings. There is no fudge factor here.. 360lbs may even be a little on the high side. While it is sometimes a little nerve racking making landings in the surf, I have yet to take on any more water than a little splash or two. It would not be wise to push the limits of this little craft... The weight limit MUST be adhered to unless you get the RID kit, which I feel gives you a little more wiggle room. I ran it around with a 6hp outboard for a while, never going past 1/4 throttle mind you! It does flex quite a bit, which takes some getting used to. Added two little wings to the transom so it would sit flat on my foredeck. Sailed with it lashed down offshore and found it to be a reasonable comfortable thing to sit on and brace up against during foredeck work.
Overall I give this thing a ok to good rating, three or four stars. Its not a super great performer but gets the job done at a reasonable price.
My WB8 still has all the original hardware and equipment with the exception of the main sheet system and lower mast section which I lost overboard years ago.
