Talking to the berth holder next to my yacht admiring his newish deck, and asked him his honest opinion, looks great, but DO NOT WALK ON IT WITHOUT FOOTWEAR! it gets so hot it will burn your feet and heats up the cabins below. "Much better off with teak as opposed to man made plastic/resin type decking." So thats his opinion, my opinion looks great, and probably ok in UK SUMMERS.
Hope this helps.
