I worked on a commercial boat doing this out of Gloucester. Should have stuck to clamming.
We worked Stellwagen and caught a dogfish on every hook. We had a 7 ft hydraulic spool on deck fairleaded to a davit with a braided tarred ground line. We used snap clips and gangions made out of tarred 54 thread about 3 ft long each. Worst job I ever had. What a mess.
I know tub trawl set ups are popular for smaller boats. A lot of that stuff down in Chatham. To the best of my knowledge, they bait up before leaving which is probably the way to go.
Not sure how easy it would be to haul by hand. The old dory handliners would use a "gurdy" which was basically a hand crank winch set in the rail. Maybe something like that. They do have electric haulers now that are popular with Quahaugers. That might be handy.
BTW, Dogfish are regulated pretty closely now. Just say'in.......
