An unverified ramming story from convoy fighting

The story was heard during research at Churchill College, but the supposed Royal Naval Volunteer Reserve officer has not been identified and the exact action has not been found in a source. In the account, the officer strengthened his boat's bow while preserving enough speed and handling to operate with the flotilla. The boat waited inside the convoy until infiltrating E-boats accelerated for their attack. Its crew then poured heavy gunfire into one craft and rammed a second hard enough to split it. The explicit caveat matters: the story illustrates the dirty, improvised character attributed to coastal fighting, and it should not be treated as a confirmed action report.
