The repairs on this deck are questionable at best.
Pressure treaded wood has no place on a boat, period
Although the oak "up-rights" sistered to the frames look ok, its the pressure treated 2 x 4 that I don't like. look at the piece of wood on top of the up-rights, you can see there are only 3 growth rings about 3/8 of an inch apart. this is construction grade wood from Home Depot. Even though it is not in direct contact with salt water it is in an area where water will be running off the deck above and seeping into the seam between the deck and the 2 x 4. Now When you rip a pressure treated 2 x 4 "or any dimension" you can see that the pressure treating does not make it to the center of the piece of lumber. Now that the lumber is ripped, and the untreated wood exposed, it is just a mater of time "a short period of time" before the wood starts to rot. Another problem is the way the up-rights are connected to the 2 x 4, I am not one to just board someone's boat so my inspection of this connection was limited. It looks to me that the 2 x 4 is laying on top of the up-rights with epoxy of some type and hopefully a fastener somewhere. If there is a fastener going from the 2 x 4 down into the up-rights, it will not hold very well at all.
