My Sampson post is welded to a steel deck.
How much weaker is bronze than steel?
The essence of this conversation is that stoppers need to be strong.
So why choose a weaker material than the norm ... steel.
Did that cleat rip out because the forces were more upward than horizontal?
To me, the deck in Garbler's photo looks very thin. Admittedly, I've only cut into one deck, my own, but it was much thickerer than that! I estimate mine was 3-4" thick at the foredeck.
Are foredecks that are this thin commonplace?
Ps- depends on the boat. There’s different audiences for boats. Some are directed at world cruisers and are designed and built to function in serious weather, high lat or the southern ocean. My concern is EU A rating. It implies at the time a boat is newly completed it will function and survive force 8 to my understanding. Think people sometimes misunderstand this rating. It doesn’t mean the vessel will tolerate the use and abuse of cruising.
Once was involved in a small boatbuilding company. This was before prepreg, CF and even current resin infusion/vacuum bagging being commonly done. Back then you could pretty much cost out production by weight of the vessel. Strong heavily built boats cost more. Properly done systems cost more. Backing plates instead of washers, eliminating core under fittings, and proper sized and quality fittings cost more. In the current era strong light boats achieving that level of build cost even more.
