But IS modern equipment really that much lighter? Which bit?
Modern sails, for example, are comparatively heavy. Here's some examples I measured and posted a while ago;
Hobie Miracle 20 fast catamaran racing jib, 5.1m = 2.45kg bulletproof dacron
Laser Radial mainsail, 5.7m - 1.85kg with battens
Windsurfer One Design, 6m mylar 2.22kg with battens
Windsurfer One Design, 6m dacron, 1.58kg with battens (the original windsurfer sail)
Tasar dinghy mainsail with full battens, 8.3m, 2.7kg (mylar/kevlar)
28' offshore racing yacht No 1 headsail, about 20.6m, 4.9 kg (mylar scrim)
18 Foot Skiff headsail, about 10.8m, battens removed, 3.9kg (kevlar)
Average modern 6m windsurfer sail with battens - about 3.6kg
The board I first bought for learning was about 3m or 3.3m long, and was made from either plastic or fibreglass. I can't remember. But, it was heavy compared to the epoxy composite boards that were around at the time. I was surprised at how light they were in comparison.
Similarly, I taught myself mainly on a windsurfer one design or a clone, on Lake Illawarra, and with sails that were small enough to get going, but nowhere near the size required to plane. So, I was surprised when I went to the newer equipment and found that it was easier to lift, and the sails appeared lighter. I think the shape of them also made them more user friendly compared to the old style sails that I had.
So, whether they were lighter or not, my recollection is that the newer stuff was. I certainly found the newer boards much easier to ride, but that could have just been because I had already sorted out my balance on the OD stuff.
