Chest harnesses with harness lines miles apart and the vulcanized boom grip that tore the skin off your hands, Those were the days.
I think the earlier Bombora boom using the cut down windsurfer original stock alloy boom with extensions had softer grip than the later Bombora boom. I did not use that later one. Gaastra chest Harness with spreader bar worked fine at the time. Also wide harness lines worked fine as I recall enabling the kind of reactive stance needed to promote speed and to avoid spin out and for optimising rig geometry given volume forward due to board and in light of sail design and mast track forward. Kind of like in some cases a prone kangaroo stance as subtlety shown in this video by Mark Paul. The Gaastra powerhead horizontal panelled rainbow sails of 1983 setting on blue Gaastra mast were light and good sails even though fully Dacron (stretched earlier than Mylar) and had shorter booms, more refined design and higher aspect than the Gaastra Bombora vertical panel sails.
