By the late 70’s I had completed some eleven years of active  duty military service, was newly divorced and grappling with being a single  parent, getting reestablished in the civilian sector, following the labor  market from SC to RI, and eventually getting remarried.  It wasn’t until the 80’s, a decade which  found me happily up to my neck in old wood, that I could seriously get back to  boats--an ancient Malabar Jr. followed by Wiano Sr. followed by Rosborough Brigantine, followed by a Crocker ketch,  all stuck together with dreams of a new construction school-ship dancing in my  head. 
                Interspersed between the boats were the formation of a  non-profit outreach program and the incorporation of my boat shop.  Then came the 90’s: the economic downturns,  no more work coming into the boat shop, my wife’s cancer, embezzlement of funds  by the then president of the non-profit and the general loss of dreams.  
                The 90’s however passed; I picked up work at Concordia on WallyGator, freelanced as shipwright on  the Bounty, got picked up by Raytheon  for some submarine work due to my previous naval background, moved off the  Crocker (home for some five years while the storms of life raged overhead) and  bought a house with detached double car garage (aka boat shop). Boats again  became a thing of dreams, albeit, little ones.  
                My years in the non-profit and as licensed skipper had seen  the development of inclining tests, stability calculations, school ship  documentation, commercial ship documentation; many dealings with a variety of  Coast Guard offices and living inside the Code Of Federal Regulation.  Too, my years in repair, restoration, and  sawdust had taught me the care of building new vessels. Throughout all I had  kept my beloved library on boat building: Chappelle, Stewart, Gardner, Simmons,  Culler, Gudgeon Brothers, Hill and Oughtred among others; all extolling the  creation of small craft—usually traditional, sometimes regional, all of wood in  its various forms. 
                Now I have reached the age when people begin worrying about  pending retirement—thinking that knocking out a boat now and then in my spare  time might help make ends meet and establish a hobby to keep me busy in later  life...
                Then along came a miniscule 85 pound 9’ 8” rowing skiff  sporting a napkin sprits’l bringing with it brouhaha the likes of which none of  these books or experiences had prepared me—the Tetra.
                
                Before going further, I need to digress slightly lest I give  an improper view of things.  Actually  what came along were two vessels, well the plans for two (o.k. o.k. many sets  of plans—but ultimately two which I decided to build).  The first was the Selway-Fisher Islay Skiff;  a 16’ double ender of either lug or gaff-cutter rig, and the second was the  Tetra.  The Tetra all along was intended  as the means to the Islay.  I had enough  “disposable” income to purchase the materials for a Tetra but not an  Islay.  I did however have time on the  weekends, which could be put to good advantage.   Therefore, the Tetra became a “spec” boat  with which to demonstrate my building abilities and secondly to fund an Islay  Skiff.   I talked this over with Tetra’s  designer, Steve Redmond and had a gentleman’s licensing agreement for follow-on  hulls.  The stage, as they say, was set.
                Boats unfold at a pace all their own.  I knocked together the molds & jig in the  fall of 2006, got the transom, inner stem, and chine logs hung and put things  away.  Winter found me sail making,  spring involved in readying Sea Minor (10’  Cape Dory) for sale and subsequently  getting an antique Blue Jay in the water.   Summer of course was spent messing about IN boats.  Thus it wasn’t until Columbus Day weekend  2007 that the Tetra again rose to the surface.   Skipping ahead to January 2008, the Tetra is fitting out: hull structure  complete, trunk installed, thwarts and mast partner going in.  Time had come to think about marketing and  PAPERWORK.  Enter the brouhaha.
                In Rhode Island, where I live, the Department of Environmental  Management Office of Boat Registration & Licensing is the place for  boat-associated paperwork.  Their web  site lists everything needed to register a newly purchased boat.  Unfortunately it also completely neglects  home building.  “Questions—e-mail  us.”  I did.
                In my honesty and, I suppose, naivety, within the body of  that e-mail I mentioned my intention to sell the boat—little did I suspect I  would soon be entering unfathomable Federal waters.  
                You know those little number things molded into the transoms  of plastic boats—the Hull Identification Number?  EVERY boat built in the U.S. of A is required  by federal law to have one.  For homebuilders I refer to Title 33: Navigation and Navigable Waters Part 181—Manufacturer  Requirements.  Here four key things are  important to know/remember:
                
                  - First:  181.3 Definitions: “Boat means any vessel—(1)  Manufactured or used primarily for noncommercial use”; “Manufacturer means any  person engaged in: (1) the manufacture, construction, or assembly of boats...”
 
                  - Second: 181.23 Hull identification numbers required (b) “ A person who builds or  imports a boat for his or her own use and not for the purposes of sale, must  identify that boat with two hull identification numbers that meet the  requirements of this subpart:
 
                  - Third: 181.31 Manufacturer identification code assignment (c) “persons who are required to  identify boats under 181.23(b) must obtain the required hull identification  number from the State Boating law Administrator of the State where the boat  will be principally used, or, if the State Boating law Administrator does not  assign these numbers, from the Coast Guard District office in the area of  principal use.
 
                  - Forth: 181.29 Hull identification number  display—Two identical hull identification numbers are required to be  displayed on each boat hull.
                    
                      -  (a)  The primary hull identification number must be affixed—
                        
                          -  (1)  On boats with transoms, to the starboard outboard side of the transom within  two inches of the top of the transom, gunwale, or hull/deck joint, whichever is  lowest.
 
                          -  (2)  On boats without transoms or on boats on which it would be impractical to use  the transom, to the starboard outboard side of the hull, aft, within one foot  of the stern and within two inches of the top of the hull side, gunwale or  hull/deck joint, whichever is lowest.
 
                          -  (3)  On catamarans and pontoon boats which have readily replaceable hulls, to the  aft crossbeam within one foot of the starboard hull attachment.
 
                          -  (4)  If the hull identification number would not be visible, because of rails, fittings,  or other accessories, the number must be affixed as near as possible to the  location specified in paragraph (a) of this section.
 
                        
                       
                      -  (b)  The duplicate hull identification number must be affixed in an unexposed  location on the interior of the boat or beneath a fitting or item of hardware.
 
                      -  (c)  Each hull identification number must be carved, burned, stamped, embossed,  molded, bonded, or otherwise permanently affixed to the boat so that  alteration, removal, or replacement would be obvious. If the number is on a  separate plate, the plate must be fastened in such a manner that its removal  would normally cause some scarring of or damage to the surrounding hull area. A  hull identification number must not be attached to parts of the boat that are  removable.
 
                      -  (d)  The characters of each hull identification number must be no less than  one-fourth of an inch high.
 
                    
                   
                
                Back to Rhode Island for a second:  On the phone, DEM readily stated that they  did not title boats of 14’ or less, but were less forthcoming on the topic of  registration—even providing a fee table on their web site indicating boats down  to 0’ were applicable. However, with some digging on state sites I found that  canoes, kayaks, rowboats of 12’ or less or boats used primarily for racing were  exceptions to the registration requirement.  
                I asked Dan McCormick of the Coast Guard’s Recreational  Boating Product Assurance Branch if such a minimum length requirement applied  to the Hull Identification Number.  The  answer was no, accompanied with a copy of the Title 33 Part 181 requirements.
                Ok, as to the Tetra.   Remember I mentioned my intention to sell the boat.  Such intention precludes me from falling  under the homebuilder criteria.  RI DEM  informed me I required a Manufacturer’s Identification Code (MIC) in order to  (1) originate a Hull Identification Number and (2) prepare a Statement of  Origin (initial title) and referred me to the Coast Guard.  (This is how I first met Dan McCormick—and I  must say he has been a most pleasant person to deal with.)
                The MIC request must be made in writing on the applicable  form to the Coast Guard Recreational Boating Product Assurance Branch.  Said form requires identification of company  name, State of incorporation, Business License, and design/model information—in  other words you MUST be a formally established and licensed business in the  State in which you intend to build boats (according to Dan this does not  mandate you be incorporated—you must be a formal licensed entity).
                Spare time building for me means knocking out a boat every  couple years.  If one boat, such as the  Islay Skiff, happens to be a keeper, then perhaps four years between  sales.  Not exactly your rip roaring  business.  In my days of running an  incorporated business/boat shop I was subject to taxes on my tools, taxes on  inventory, “voluntary” contributions to state and local law enforcement  programs—“the cruiser will come by to pick it up...” at 2:30 in the morning  outside my shop door.  
                Of course there are other legalities applicable to  non-homebuilders associated with Part 181:   labels, tags, certifications etc. but these are minor when compared to  the formalities of establishing and maintaining a formal business entity even  if it resides solely on paper.
                So home builder beware, perhaps it once was better to seek  forgiveness than permission and ignorance was bliss, but RI DEM Office of Boat  Registration & Licensing has a slogan, “No Numbers, No Papers” and the  Coast Guard is no longer with the Department of Transportation.  They are now with Homeland Security.
