A view in profile might be helpful. Lots of dinghies are set up with side tanks. Your bow opening in front of the splash rail is interesting.  Does the spinnaker hoist from there? Stepping the mast aft of the bulkhead is also different from most arrangements.  It looks well thought-out, possibly a French or Spanish design for the Mediterranean, or maybe from Florida, because it is bound to be wet with the centerboard slot in the bottom of the cockpit and that would be too cold to become popular elsewhere.  The large flaps in the transom are an indicator of how much water comes aboard. The hardware does not seem too American.  You may have a quicker answer from this site: https://www.forumvoile.com/phpbb3/ ;  its focus is on dinghies.  It would help to speak French there.
