Recently people have been joining me on my Sunday Walks in Downtown Albany. Typically, I walk in Albany when I'm scheduled as a tour guide on the USS Slater. A slide show and a map are detailed at this blog entry. I plan on walking on Memorial Day, Monday, May 27. You can contact me at: dedocent@gmail.com.

06/06/2010 - DE 5K Walk

On the 6th of June I had planned a 5K walk in downtown Albany. I arranged discounted USS Slater tour coupons for everyone who participated. Unfortunately the 6th of June was a washout, and the DE Docent had to walk alone.

Albany is a great place to walk. I outlined two 5K walks with the USS Slater as a starting point. The 1st is a walk was along the the Corning Preserve. (about 1-1/2 miles). It includes a quick loop to the State Capital. The 2nd walk goes along Broadway, toward the visitor center and the AquaDuck Tour (also finishing with a loop around the capital).



This week was very hectic. During the week I came to the Slater several times and gave three tours to School Groups. While the groups were rather large, everything went well. The chaperons were great, and the groups were well behaved.

On Sunday despite the rain, I managed to give two tours to very small groups. The 1st group was just two people, who had recently completed a week long bicycle trip along the Erie Canal (basically the length of NY State). The 2nd group was largely comprised of a group of visiting engineers who were in Albany for a training program (of course this led to quite a few technical questions).

What is the range of Sonar? - This is not an easy question to answer because of the impact of environmental factors. Norman Feidman's book on Destroyers in WWII cites 2,000 yards (page 196). U-boat Net has an excellent article on the topic and cites and average of 1,350 meters. These ranges are for active sonar. In contrast ranges for passive sonar can be a high as 100 kilometers for a very noisy sound source like a convoy.
