Jeff~
re a sailing rig on a duckboat - I could not agree more. I always look longingly at Barnegats, Delaware Duckers, Melonseeds and Seaford Skiffs under sail and wish I had a spot where I could use one under gunning conditions. My Scooter has the partners and step for a mast - and I even built a mast and sprit for it years ago (the mast resides in my loft with all of my other spars from my other sailboats) but never sewed up a leg o' mutton sail. I envision sailing lazily homeward (downwind) after a morning's hunt in the open bay.
As you know, both boats started out as "workboats" but were later developed for yachting. They were developed before engines and so oar and sail were the motive power for which they were designed. The Barnegat was built for sailing primarily on water - with its trunk, daggerboard and even rudder sometimes. It evolved into larger boats intended for racing under lots of canvas in the warmer months. The rigs got larger along with the hulls but the basic shape of the hull did not change.
The Scooter was built primarily for getting across a frozen, saltwater bay in all its forms. It could be dragged, piked, kedged (with a grapnel), rowed and sailed. The early boats had no jib and could sail only off the wind. As it evolved into a sailing yacht, its rig got much larger and a balanced jib and jibboom were added for steering. The Scooter's hull was changed markedly for yachting. Its rowing and hiding and seaworthiness capabilities were reduced in the modifications to its hull and cockpit shape. Its ice sailing capabilites were maximized at the expense of its gunning characteristics. (Come to think of it, I've never heard of anyone taking their Scooter out for a summertime sail.) The biggest difference is the beam. Whereas a gunning Scooter was generally around 42 inches wide, the sailing Scooter was in the vicinity of 5 or even 6 feet. (I should note that some Scooters were built with very wide beams - the so-called "pumpkinseed scooter" - but these were specialized for open bay gunning, developed in response to the ban on batteries; like the batteries -and the layout craft developed independently on the Great Lakes - they were set out and tended by larger craft - they were not a self-contained unit like Barnegats or gunning Scooters.) The cockpits became just a well for the purpose of putting the crew's feet and did not need to hide them in a gunning position. The yachting Scooters were designed to race and so, like most things designed for racing, they became impractical for other, more utilitarian uses.
So, you could hunt out of a Scooter designed primarily for sailing, but you would need to pick your weather more carefully and maybe modify the cockpit - and be prepared to handle a cranky boat once you're afloat. If you wanted to sail, you would need to make a much smaller rig - with spars that could stow beneath the decks. If the need for a Scooter is to get over the ice so you can hunt an "air hole", the gunning hull would be much more effective.
BTW: Ain't it the specialized nature of duckboats that makes them so much fun?!
Hope this is helpful,
