I believe that all of the Cherubini designs were originally outfitted with Gray plastic portlights. With the age of the boats, probably most, like the ones on my 79 H33 are well past their prime. Outside lips on mine had broken into sawtooth edges, just right to lay open an unwary ankle hurrying forward. I have just received a full complement of original equipment replacement ports from Thrifty Mariner, www.thriftymariner.com, telephone 813-625-8466, and the price of the lot, six 7x15 and five 5x12 was $411 delivered, a small fraction of the direct from manufacturer cost. These are seconds evidently, since there are defects like ill formed screen lugs and mis drilled drainage holes but nothing that would prevent a first class installation. Though Thrifty mariner was quite slow in shipping, my credit card wasn't charged till they were shipped and the price makes a strong recommendation.
