Thanks for that Roadrunner!
You're right about me being on a roll!
I was going to add just one each of the 4" and 5" hatches but it ruined the symmetry of the Oasis. As they were cheap and easy to fit I thought why not two each?
I used to think of our tandem as looking like a banana but now I'd say it more resembles a slice of Swiss cheese!
Despite the abundance of holes we are still going to have to carry the larger gear above deck as an 8" hatch hole is not big enough. The Oasis could really do with a larger hatch as on the other models but I know there just isn't a place to fit one.
I'm hoping the need for a larger hatch is recognized by my wife as a legitimate excuse for upgrading to the Tandem AI if and when it becomes available!
PS: I have stopped now though, so no plans for a kitchen sink!
