The key ingredient to a smooth blow through gybe with a Gennaker is the smoothness of the clew against the forestay.
Rooster has produced a large range of UMHPE links with half circumference (or max width of the loop when pulled out) of 40mm, 55mm, 60mm, 70mm, 100mm, 120mm and the Gennaker Link shown here at 240mm. Red is our colour for our Gennaker sheets, hence we used red for the Gennaker link.
