I own a Scout (hull number 4) and I'm a pretty big guy who had trouble looking under the mizzen boom when navigating. And my passengers in the salon cockpit really had to duck when coming about. So last year, I constructed mast tabernacles (so I could fold down the masts for transport).
Since I had to cut the masts into 2 sections anyway (to install the tabernacles), I discarded the lower sections and replaced them with ~19" longer sections. The net effect was to raise the sails (and booms) by 19". For this to work, the tabernacle obviously has to be installed lower than boom height. I've sailed it for a whole season in some pretty stiff wind with no problems. Much more comfortable for me and my crew.
And yes, you need wedges to shore up the masts.
