Thanks for your response. It is a sparcraft. I contacted rig rite in June of 2019 yes 2019 and someone in Rhode Island visited the company for me in January 2020 as they would not respond ro my many phone calls emails and prayers. My friend that visited the rigrite shop advised me that they could not obtain the measurements from Dufour. Sparcraft in NC was unable to help. I am now working witn Sparcraft in Plymouth ,England. I need to find a sister boat to obtain the measurements. It has been reported that Dufour is closed due to virus.
