My husband used to say "Is this a hill you want to die on?" when I would be battling with one of my teenagers back in the day. I agree with the previous post. You will have to get rid of the boat at some point but perhaps it is not worth the angst to try to do it now especially because it seems to be very important to him. I am for not "rocking the boat" (pun) during this dementia journey. There are more important issues on the care plan right now. Though I can appreciate wanting to downsize and simplify our lives with all the other challenges we are dealing with. Right now I am sorting through my husband's skiwear and gear, cabinet making tools. We spoke about how we will likely never go skiing again or pick up his woodworking hobby and would it be ok if I sold/donated these items. He thought about it and said ok. I think it's important to give him the right to refuse.
