HH are handlaid with resin squeegeed out for even and consistent wetting out of cloth
buccs are chopper gun with variable thickness - in some hard to spray areas its thin and in others the resin/cloth ratio is excessive were gravity has pooled it
chopper gun boats tend to be heavier to allow for this variation.
my personal experience was the bucc was poor in a few areas - stress cracks around some deck fittings. also found that the stitching in the cockpit seat upholstery rotted out rather quickly. the also use that caramel coloured gelcoat on the inner liner - and in areas like the side pockets where rods/gaffs/nets etc live it quickly scratched through to reveal white behind.
the dealer also cut some corners with the fit up - no backing plate on the throttle for instance - that was a surprise when the screws pulled straight out and the throttle came away from the helm side console one day...!
i believe that all HH are now factory fitted out at MMSC in ellerslie - so the rigging/wiring/deck fittings are all installed appropriately and to consistently high standards.
in terms of hull performance - the 535 is an old design now - from when volume for length wasnt such an important selling point (compare to the newer 545 for instance for a old/new contrast in design thinking) - and as such tends to be a much better traveller for it - better behaved at slow to moderate speeds.
the bucc is still a nice hull - its just it doesnt like going slowly (18-25mph sort of stuff) - but crank it out to more like 35+ and it tends to come right
