    Ad Hoc Naval Architect

    Ditto in the UK - anyone can legally call themselves a Landscape Gardner or a Naval Architect (the only 2 professions) without any formal or otherwise qualifications or membership of any professional institutions.

    You only have to satisfy the regulations and pass an inspection/survey - in that sense - ergo, anyone reading the rules can do it... and if they don't read the rules correctly... the surveyor will simply point out the non-compliances anyway.

    The USCG has authority over vessels carrying passengers for hire and the crew of such vessels in Federal navigable waters, which are basically all coastal waters and any waters connected to coastal waters which could be or ever were used for interstate commerce. https://www.law.cornell.edu/cfr/text/33/part-329 States have authority over and set the rules for vessels carrying passengers for hire and the crew of such vessels on other waters.

    That's what I couldn't find searching Florida law and regulation sites. It seems to be circular, FWC points to HSMV, HSMV points to FWC, and state statutes says "the commission" will set the rules...

    You can't find a law or rule that doesn't exist.

    The question for the original poster is he operating in Federal naviagable waters or state regulated waters?

    So you boat needs to meet USCG regulations, not Florida state regulations.

    Do you have a speed requirement?

    Eastern in New Hampshire build semi-custom commercial boats with USCG certification available. They have 27 foot and 30 foot hulls. https://www.easternboats.com/commercial-boats

    Contact them....but remember to state that you need it registrable to Subchapter T for XX passengers....It is a lot easier to build it into the vessel than to prove it afterward.

    As jehardiman said contact them and tell them what your needs are. If they are unable or unwilling to do all the work themselves they are likely to know of a builder who can.

    Another possibility is a Duffy 26 launch by Atlantic Boat. The standard model is USCG certified for 24 passengers and 1 crew. Atlantic Boat also builds 29 foot hulls (and larger) and has done outboard versions of several of their boats which significantly reduces the draft. They are relatively small and used to building boats to customer requirements. Duffy 26′ Launch | Atlantic Boat Company https://www.atlanticboat.com/duffy-26-launch/

    You won't know if a builder can meet your needs without asking.

    1) NVIC 10-92 gives accelerated review to submissions by a P.E., but a P.E. is not required. Our shipyard needed very fast turnaround for a 49 pax boat, and the fact that our calcs and drawings were stamped may have helped avoid delays. I have noticed here on the Chesapeake that new builds and conversions generally have had a P.E. do the stability and similar calcs as a minimum.

    2) A one off aluminum boat might be feasible for this. Our shipyard frequently built such boats, though usually for 30 - 149 pax.

    3) You could get a design and CNC files for such a boat from the right designer and have it built.

    4) Review the regs and contact your local CG office as a first step.

    5) Actually in any state you have to have a P.E to offer "engineering services to the public"; basically to use the "e word" as a title, etc. in such a way as to imply you are licensed. However, practice of engineering is more complicated, and most of small craft design is considered unregulated drafting services. In terms of small vessels, 46 CFR 28.500 cites that a person having knowledge of naval architecture is required to develop stability instructions for certain fishing vessels and this might trigger a requirement for a P.E. in some states, but the insurance underwriters have required stamped stability documents since well before 28.500 was in the rules anyway. (And they are the only reviewers for FVs anyway.)

    6) If you are not in a big hurry go to the International Workboat Show in New Orleans next fall (usually Niv. - Dec.) and look around. It is usually free to get in to the exhibit hall.
