That is something I think most people seldom take into account. Full time live aboard folks and distance cruisers naturally will have more stuff packed away, that's just a fact. What baffles me is the amount of pure crap some folks have aboard for weekend use. Talking to folks at the marina and reading posts on this and other forums simply amazes me.
Fair enough if your weekend trips are in Alaska(or some other equally remote location) but most folks are never more than 10 miles from a marina and have more crap stuffed away than they could ever hope to find, let alone use. I know a weekend warrior with 6 anchors and enough parts to rebuild both his engines and generator and enough tools to construct a dock to tie up his 35 foot boat. There's a fine line between being prepared and warehousing. Nothing wrong with either but if you use your boat as a warehouse don't be surprised if the top end ain't what it could be.
I recommend seeing if your boat needs to go on a diet before digging too deep into the problem Chris. An extra thousand pounds of stuff(not at all hard to accumulate) wont hurt the performance of a 40' long 7-9 knot boat much but it will really be felt in a 35' planing hull.
