Hey guys, I have been wanting to put a floor in my 1648 for a little while now. I was at the scrap yard the other day and found a whole pile of 30"x30" road signs. I decided that this would be the best and cheapest route to put a floor in. I was able to pick up enough aluminum signs for $50. below is a picture of them just laying in the boat, i will cut around the ribs and piece them together so that it is smooth. i plan to cover the floor with a roll of the cheaper hydroturf material you can get at hardware stores. More updates to come. One question i do have, should i seal all the rivets in the bottom of the hull before putting the floor in? i dont have any bad leaks, but a couple slow seeps.
