RE­SULTS

Canal Boat - - Insulation -

Two as­pects im­proved with fit­ting the in­su­la­tion; noise and vi­bra­tion. Noise re­duc­tion was sig­nif­i­cant, par­tic­u­larly no­tice­able at lower revs. We nor­mally cruise at 1,300rpm, so over­all noise was re­duced - 8dB. Vi­bra­tion re­duc­tion was also sig­nif­i­cant, al­though we couldn’t think of a sci­en­tific way to mea­sure it.
