My own experience: 5 years living aboard a 30' triune trimaran, sailing 30,000 miles ( in the 80's ). Many fishing methods are no longer sustainable -- bottom trawling is recognized as causing a great deal of damage to the seabed, and most fishing with nets results in many fish being caught that need to be thrown back (dead) because they are too small, the wrong species, or the fisherman has reached his quota of that species. The most sustainable method of fishing is using hook and line with fishing rods jigging machines. If a sailboat is used for this kind of fishing, no fuel would be used searching for the fish.
Speed -- fishing would typically be done in light or very light wind, so that the boat doesn't drift too fast whilst fishing. On a large (around 40 feet) trimaran, fish can be stored in the outriggers, keeping the catch and the accommodation separate. I have looked into the practicalities of getting a commercial fishing licence, using the fish market, and in having a trimaran certified as a commercial fishing boat and so on and there seems to be no problems at all. If the enterprise works, it would be great to design and build a boat specifically for fishing. I am posting this plan here because I would like some feedback on which designs might be suitable -- there may be some haven't given sufficient consideration. Cash flow will be constrained by the amount of fish caught which is constrained by the time it takes to catch them and get them to market. The first question is what level of capital investment will the return on 2 tons of fish per week justify? The level of capital that can be justified by the anticipated return will determine the costs and capabilities of the vessel and the design spiral continues. Location: UK, USA and Canada Jim Brown and Dick Newick did something similar for the third world years ago. Some fisherman may prefer the monohull slow roll, but I hate it - especially that crazy becalmed roll in a swell that builds out of nowhere, till stuff is being thrown about the cabin. Location: USA I believe a cat would be better than a tri for this purpose, because cats can carry more weight, given low-resistance hulls and similar length. Obviously, being only 16 feet long, Slider isn't suitable for a commercial venture, but we've been catching all the fish we dare to eat. To Longliner: Catamarans were used for offshore voyaging in the Pacific long before Ohio was discovered, and probably before the Falmouth working boats were first built.

They didn't have catamarans, but at least they were smart enough to go for a long thin efficient hullshape, so they were halfway there. Location: Fox Island I made a couple trips longlining on a 54' Skookum sailboat.
When making potentially dangerous or financial decisions, always employ and consult appropriate professionals. Location: spain Sailpower by Wallace Ross and Elements of Yacht Design by Norman Skene are on everyones bookshelf. Here is one asking for professional advice and assistance, not for your anecdotal tales and babble.

I've been sailing twice, aboard my friend Brians 28 ft Pearson Triton, enough to find out that sailing is quite fun.
His books are studied by all serious Naval Architects and maritime historians researching fishing craft from the age of sail.
Location: NW Washington State USA I think we kinda sorta had this discussion before and concluded that a Grand Banks 36 took 50 hp to make 7 knots and a Willard 40 took 23.

And w bulbus bows I always wonder why they don't just make the upper bow as long as the "bulb"?? The cost of modifying the bulb runs over $1,000,000 so many are accepting the poor fuel results , in the hope the trade will resume ,,someday. There ARE fuel savings from going slower , as in every boat , the savings are just nor optimum.When the gas bill is in Tons per hour , everything counts!
Another fine place is the Peobody Museum in Salem, be sure to Visit the Salem Maritime National Park while there.
For a real authentic experiace go to Gloucester and join the crew of the Schooner Adventure. I would eliminate the back cabin that a lot of them have and install refrigerated fish boxes in the decks. As for accomidations 4 bunks in the bow and a gally with stove, sink & diesil cabin heater. If I describe my project, I hope I might stimulate some discussion on its practicality, and also design features I should be looking out for.
Centre cockpit, fast, the capacity to carry 500 kg in each outrigger (and foam sandwich, helping insualte the catch and the ice), comfortable and with the added bonus of being capable of taking me to a more equable climate in winter. That's quite a bit narrower and I don't know how much weight I can carry in the outriggers. I can't see why trawlers working in a sheltered estuary would need more than one hull - they just need the pulling power of the sails.
Lobster fishing is very popular business in this region due to the high demand on this product from local hotels and restaurants.
I figured the GB would take about 75 hp so even though the real life difference was less than I thought a bit over 2 times as much is not fly stuff. You may want to search this area as they seem to be readily available and would probably be priced reasonably.

A typical trip might be sailing out overnight, fishing for a day, and sailing back through the next night. It was so intense, I had to move from the anchorage near town, and find a secure place up river. Guillermo could fix me right up, but i've no idea how much NAs charge for preliminary sketches. Without ready capitol (read rich family) most fishing ventures fail anyways, so if it fails i'd at least like to have a sailboat to show for it. When I bought my last boat I put too much emphasis on fuel burn and now am wishing I had a boat that burned twice as much. Perhaps there's something about the bulbus bow that makes it WLL wise butter than just making the whole bow as long as the bulb???
Nothing like comming abourd on a cold winters morning for some bacon & eggs and a hot cup of coffeee cooked on the wood stove in the galley. Those oystermen were out there in the estuary in what must have been a force 10, still trawling, with just a scrap of jib up.
I could spend 1-2k at this point, but i'd like a better idea of what I want before I do that. I know Edwin Monk designed some but his plans are no longer available according to Mr Monk Jr in Bainbridge WA. The boats that do this kind of fishing have no accommodation and so fish one day at a time. But if I treat the boat as disposable, having virtually no resale value, I'd be free to make whatever changes necessary, and it would give me the chance to test the feasibility of selling directly to the public.
Could anyone recommend some books on sailing or boat design to a give me a few ideas about options? My costs are the pay for one other person, a little fuel, ice, lures, harbour dues, boat maintenance. I'm looking at a big old fish boat conversion now and am a bit scared of the wood ship construction. I've looked at George Buhlers designs and they are very nice but I was hoping I could find a source for the plans from a historical source. The Clarem, as I found her this fall at Edna Bay on the outer coast of Prince of Wales Island. I'm also looking at a Nordic 32 and I'm sure you'd say go w the Nordy but with my eye on the big old serious fish boat I may better be better able to see what the Nordy really is. Also the wood fish boat I'm looking at is very much like the 40' troller by Frank Fredette.
