After giving up and not wanting to carve up the deck of my H25, I made a plug and had a friend at Vanguard lay one up after I sold it. After I made it, the person I sold the boat to insisted I put it on and privide hardware after our signed agreement stated I would provide him with the hatch only. I thought about it, but by the time I got the thing made, the weather had turmed. I brought it to him and offered to put it on when it was warm, as I didn't want to work on his deck in the cold and crack something, and I did not think the epoxy woudl cure. having recently lost my job, i asked if he could give me the with held ($600) money so i could get the hardware and finish it and he said no. So, I have decided to sell it here. I can send pics and it fits like a glove.
