<p>The boat has separate front and rear sections, with the rear section (6) holding the propulsion unit. The coupling (13) is such as to allow the motor section to be pivoted to raise the screws clear of the water for maintenance. The coupling has self centring stubs (13) as well as the pivot bearing. When used for a fleet, extra propulsion units ensure that the fleet is not out of action thus saving on numbers of craft.</p> |
