<p>The invention disclosed relates to a sunroof system designed primarily for a pleasure boat. The system includes a panel (12) moveable between an open and a closed position. A motor driven chain (17) is provided, held within a guide rail (10), to drive the panel (12) between positions.</p><p><Paragraphs id="pa02" num="0002" xmlns:base="http://www.sipo.gov.cn/XMLSchema/base">A carriage means connects the panel (12) to the chain (17) and is supported on rollers (44) resting on flanges (15, 16) or the guide rail (10). In order to dampen vibrations and minimise noise during operation of the panel (12), a block (46) incorporating resilient elements is incorporated into the carriage means. Moreover a tensioner (80) is also included to take up or provide slack in the chain and (17), to allow for differential thermal expansion between the rail 13 and the chain 17.</p><p><Paragraphs id="pa03" num="0003" xmlns:base="http://www.sipo.gov.cn/XMLSchema/base">In order to prevent ingress of dirt, into the carriage, brushed (26) are included in the guide rails (10).
