Above is Will Hladik's Musicbox2. He has cleverly used one of our 5" clear deckplates as a portlight.
Just came across a great idea for low-cost opening ports. To give credit where credit is due, the idea came from Wes and Anna Kisting. On the Pocket Cruiser that they built for a honeymoon cruise, they used clear watertight inspection hatches with some mosquito netting glued onto the rim to keep out the bugs. I see from your catalog that you carry the clear inspection hatches (and that Wes and Anna were not the only ones to think of using them for opening ports). Still, I think it's a good enough idea to give it a bit more exposure.
The following article mentions clear plastic hatches, and they are a brilliant idea.
The actual page referred is the following:
The above page shows hatches open with a human face behind one which is very helpful to figure out.
Many thanks as usual.
