I just posted instructions and photos in the "Photo Forum" on how I modified the main sheet hardware on my 1999 H310. The insructions should work on all late model Hunters with end boom sheeting on top of the arch. It has proven to be a well working set up. No more rope clutch for the main sheet and with the 4:1 purchase, I can trim the main from the helm and do so with one hand tied behind my back.... any futher questions, feel free to e-mail me. Steve, s/v The Odyssey (H310)
