Alameda and Jack London Square - Page 7 - elf1's Photos

A quick day trip to visit the Alameda Spite House, look at some other Victorians in the area, and admire gardens. Then to Jack London Square, where we also saw the Potomac (Roosevelt's Presidential Yacht) and the lightship Relief. You may use individual photos for single use only for personal or nonprofit use.

elf1 > Interesting to see the somewhat more old-fashioned brass wheel next to the newfangled radar.

elf1 > Yours truly admiring the gorgous brass wheel.

elf1 > Ship's wheel etc. I was lucky to have a tour guide who worked on the lightboats before they were all decommissioned in the '70s and '80s. And he was a great speaker, too. John Byrne? I loved the tour. And it was free! (Unless you wanted to make a small donation.)

elf1 > Four bunks in the bunk room. The ship had a crew of 18, 12 of whom were on duty at any one time. Every 6 weeks, 6 would rotate out to shore for a 6-week leave. But they had fairly generous space, for many ships.

elf1 > More bunks for the crew.

elf1 > One of several types of lenses used in lightships' light towers over the years. This is a 375 mm lens, which was fixed in position but could flash. Two of this type of light top the Relief's light tower. Only one was used at a time; the other was a backup.

elf1 > This is a fresnel lens, commonly used in lighthouses. This one is a 4th-order Fresnel, manufactured in France in the late 1800s. The order refers to the size, from 1st (largest) to 6th (smallest). 4th order were commonly used at bays and estuaries.

elf1 > This is a DCB 10 rotating light, which produces a perceived flash as it rotates. Several are used in Bay Area lighthouses but are being phased out.

elf1 > This is the coast guard's utilitarian version of a lightship light starting in the 1960s (all lightships were phased out by the mid-1980s)--a big rotating array of bright lights with slightly different angles, which made the light more visible when the ship rolled in heavy seas.
