Which davit for 340/375 sundancer

Could do with some help in finding correct davit for swim platform. Want to have space on the swim platform when dinghy is on the davit as we can only board the boat from the starboard access and the entrance to boat on the port side so need to walk in between boat and tender. Should I use an extended davit etc any help would be welcomed? Tender would be probably be 8ft with 4-6 short outboard engine. Pics would be fantastic.
