My dinghy is a West Marine by (Zodiac) SB-4 which is the equivilent of the Zodiac S285. The only real difference is that the West Marine version has the inflatable tube seat between the two tubes while the Zodiac model has the wooden seat that attaches to the tubes. My wife is not comfortable with the inflatable tube seat and would like me to modify the dinghy to use the wooden seat. Does anyone know of a conversion package or whether or not I can purchase the patches required for the wooden seat and glue them onto the tubes to support the wooden seat?Thanks
