No orange is more brilliant on the Upper Bay than that of the Staten Island ferries.   Of course, no creature of the water–live or mechanical–sports the same colors ventral as dorsal.  And thanks to the following fotos from John Watson, let’s go below.

Here’s a thing of beauty as visible from the inside of a floating drydock at Caddell– one end of the double-ender Samuel I. Newhouse.

Note the worker for scale.

What might surprise many people is the absence of props/shafts and the existence of this disc-like recess.

Disassembled, here’s the drive unit that fits into the recess

Each of the circular spaces in this subassembly houses a vertical blade.  For an animation showing movement, click here.

Note the same transition from orange to blue to red and vertical blades here on Noble.

If you’ve wondered how these ferries negotiate into the ferry racks in adverse tidal flow, traveling sideways . . . now you know.

All fotos above except the first one come compliments of John Watson.  Newhouse fotos date from summer ’94;  Noble . . . from summer 2000.

Here’s a parting shot of one of my favorite moments of orange from earlier in 2012.
