Boat Crash with Disasters Turned off

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Turn off Disasters
2. Build Seaport and bridge in path boat takes
3. Wait for Boat to crash

What is the expected output? What do you see instead?
With Disasters turned off the boat should not crash into the bridge.  Instead 
boats crash and sometimes fires start as a result.

What version of the product are you using? On what operating system?
MicropolisJ 1.6 on Win 8.1

Please provide any additional information below.
This does not happen when using Micropolis on Mint LMDE (micropolis v 
0.020071228-7). Boat crashes never happen on that version.
