Recently Spotted: 40M Yachting Developments Hull 1015 New Zealand yard Yachting Developments launched their largest sportfish yacht to date coming on towards the end of November. Now, the near 40-meter all-carbon sportfish yacht is engaged in sea trials. From all indications, the sea trials are going decently and this yacht is expected to be handed over to her experienced owner before the end of this month. Once this happens, Yachting Developments Hull 1015 can officially claim title as world's largest sportfish yacht. Below, photos by Paige Cook show hull 1015 in action.
