On the new-to-me H33.5 1994 all control lines run to the cockpit except the main sheet. The dodger windshield is installed just aft of the traveller. The only way to control the traveller from the cockpit is to unzip the windshield (sides) and grab the traveller control lines. Similarly the only way to control the main sheet is access it through the zippers (provided the block is positioned at the extremes of the traveller). What are others doing?
