This was made probably four years ago by a guy in San Rafael who went to the Arca school. I believe it’s cedar Ronoak and it’s fiberglass over. I had it laying down right side up during the last winter where water collected inside it holds water, but it looks like a plank might be starting to let go and a rib might be starting to break. I think that a fiberglass patch on the outside would stop any leaks with that plank that might be cracked or compromised and I think that the rib could be sister. If you really wanted to the hall looks tight just the same. I’m willing to give this away if someone wants to come and take it it’s theirs.
