Yes the care put into the layup
, quality of resin and quality control can all make a big difference. I am sure HR do these things well. They produce some fantastic yachts. I had drinks recently on a 54 footer, very impressive.
However the resin used is still a second rate product. Polyester is much worse than epoxy in many important areas such as water absorption micro cracking etc etc. careful application cannot makeup for these deficiencies.
expert reported that GRP was a good boat building material, but for long term durability boats should be dried out for at least 3 months every year!. The loss of shear strength of GRP, immersed in water, with time is also quite frightening.
If they left off their teak
decks and put the savings into epoxy I might have been tempted to buy a HR.
Many people cruse successfully in GRP and fiberglass
has got some wonderful properties, but I have concluded aluminium is better material.
Yes I am biased, apologies and no offense is intended. The important thing is to enjoy cruising in any boat.
