Paradox - fit baffle

Before my "hiatus" one of the last pieces worked on was the Baffle. This is a lines of section of a cone in shape and fits inside the Transom. It's function is to prevent sloshing water or following seas from entering through the Rudder Slot on the Transom.
The thing is, when a long break is taken it's much harder to pick up the pieces again. But that's what I've Had to do this Easter Sunday. Happily, I can now know the Baffle has been glued, nailed, taped and filleted on place. Why the fuss you ask? Well of the Baffle comes away at sea, you have a hole on the Transom with no access am see no way to prevent seawater from entering the boat.
Yesterday, Bob Elliot's Building Manual was rebought because at some time over recent years a computer crash lefte without a copy. Anyway, he suggested fitting the Baffle before Assembly. That tip is worth the price of the Manual.
