Type “Maine deep sea fishing” into a booking site and you get a wall of boats, prices from $200 to $1,400, and no explanation of what you are actually buying. Here is the short version: most Maine “deep sea” trips are groundfish trips, six to eight hours offshore for haddock, pollock, and cusk, sold either per person on a shared boat or per boat for a private six-passenger charter. The half-day trips you see for less money are inshore trips, stripers, bluefish, and mackerel inside the bays.
Both are good days. They are just different days, and the price gap between them confuses people every summer. This page lays out what runs when, what it cost in 2026, and how to pick a captain without gambling on a booking-page photo.
What a Maine deep sea trip actually is
Maine DMR splits the for-hire fleet in two: charter boats carry six or fewer passengers, head boats (party boats) carry seven or more. On a head boat you pay per person and fish shoulder to shoulder along the rail. On a charter you rent the whole boat, so a crew of five splits one flat rate.
The classic deep sea trip targets bottom fish on offshore grounds. Haddock does the heavy lifting: NOAA’s Gulf of Maine rules allow 15 per person per day at a 17-inch minimum, which is why a good haddock day fills a cooler. Pollock (19-inch minimum, no bag limit) and cusk (no minimum, no limit) round out the box. Cod, the fish everyone’s grandfather caught, is now a bycatch fishery: one fish per day at 23 inches, September 1 to October 31 only.
Half-day trips mostly stay inshore for the 28-to-31-inch slot stripers, blues, and mackerel. If you would rather chase stripers from the sand for the cost of a spool of braid, that is a different trip entirely; start with our surf fishing in Maine guide.
Species by season
Charter season runs roughly May through October, with shoulder-season outliers on both ends. Here is what is realistically on the table, per NOAA and Maine DMR rules current as of July 2026:
| Species | When | 2026 rules and notes | | --- | --- | --- | | Haddock | All charter season (fishery open May 1 to end of Feb, plus April) | 15/day, 17 in minimum; the main deep sea target | | Pollock | Year-round | 19 in minimum, no bag limit | | Cusk | Year-round | No minimum, no limit | | Cod | Sep 1 to Oct 31 only | 1/day, 23 in minimum; a bycatch, not a target | | Acadian redfish | All season | Common on Bar Harbor party boats in Frenchman Bay | | Striped bass | ~June into Sep/Oct, inshore | 28-31 in slot, 1/day, circle hooks required with bait | | Atlantic mackerel | Summer, inshore | The kids-trip staple | | Bluefish | Summer, inshore | Runs vary year to year | | Shark (blue, porbeagle, mako) | Mid-summer to early fall | Federal HMS rules apply | | Bluefin tuna | Mid-summer to early fall | Tuna Maine starts trips the first week of July |
What it costs
These are typical 2026 ranges pulled from published rate sheets of working Maine operators, checked July 3, 2026. Individual boats vary; treat this as the shape of the market, not a quote.
| Trip type | Length | Typical 2026 price | | --- | --- | --- | | Shared party boat (per person) | 3-4 hrs | $41-$120 (Bar Harbor $59-$64 adult; Boothbay half-day $120) | | Head-boat marathon (per person) | 12 hrs | $210 + $20 fuel surcharge (Bunny Clark, 2026) | | Private inshore (stripers, blues, mackerel) | 2-6 hrs | $295-$795 per boat | | Private offshore groundfish | 6-8 hrs | $895-$1,440 per boat | | Shark | 8-10 hrs | $750-$1,350 per boat | | Bluefin tuna | 8-24 hrs | From about $1,350 per boat; long trips often priced on request |
The per-boat math matters. Charger Sportfishing in Boothbay charges $240 per person for a full day, or $1,440 for the same boat private. Two anglers should take the per-person seats; a family of six should take the boat.
What is included (and what is not)
Included almost everywhere: rods, reels, tackle, bait, and instruction. Offshore boats usually carry a mate and include filleting and bagging your catch. Shark and tuna boats supply the heavy stand-up gear (the Liveliner lists Penn 50-class outfits).
The license question: you do not need Maine’s saltwater registry aboard a boat whose captain holds a valid Maine For-Hire Charter Boat Operator’s License. That DMR exemption is what operators mean when a rate page says “fishing license included.”
Not included: food and drink (bring your own), gratuity (10 to 20 percent for the mate is customary; Teazer suggests 15 to 20), and on some head boats, rod rental. Watch for fuel surcharges on 2026 rates; the Bunny Clark adds $20 per person.
How to pick a captain: five checks
- Verify the license. Ask whether the captain holds a Maine For-Hire Charter Boat Operator’s License, and cross-check the boat against Maine DMR’s published for-hire fleet listing. This is also what covers your own license requirement.
- Ask what “deep sea” means on their boat. Which grounds, how long running, and what species they expect that week. A captain who says “haddock and pollock, cod only if we are lucky in the fall window” is telling the truth. One promising cod limits in July is not.
- Do the per-person vs per-boat math for your group size before comparing prices. A $900 six-hour private boat is $150 a head for six people, cheaper than most full-day per-person fares.
- Get the full cost in writing: fuel surcharge, rod rental, filleting, expected gratuity, and the deposit and weather-cancellation policy. Maine weather cancels real trips; you want to know the reschedule terms before you drive north.
- Check the actual 2026 schedule, not last year’s. Boats change their programs. The Bunny Clark, Maine’s best-known head boat, is running a pilot year in 2026: 12-hour marathon trips only, Tuesdays and Thursdays, April 14 to November 3, with no half-day option at all.
Where to sail from
Portland and South Portland (Casco Bay). The largest charter concentration in southern Maine, and the widest menu: inshore stripers and blues, offshore groundfish, shark, and bluefin. Example operators with published rates include Teazer Charters and the F/V Liveliner (an example of the local fleet, not an endorsement).
Boothbay Harbor. Midcoast base with both per-person seats and private charters; Charger Sportfishing runs out of the Tugboat Inn Marina with an April-to-December season, half-days for mackerel and stripers, longer days for haddock, pollock, and cod.
Bar Harbor (Frenchman Bay). The family option. Party boats like Acadian Boat Tours run 3-to-4-hour shared trips for cod, harbor pollock, mackerel, and Acadian redfish at $59-$64 per adult, and the crew cleans and bags the catch.
Kennebunkport. A light-tackle and fly niche, not a groundfish port: 2-to-4-hour striper, bluefish, and mackerel trips in the river and along the beaches, around $600 for a private half day.
Ogunquit (Perkins Cove). Home of the Bunny Clark, the state’s best-known deep sea head boat, marathon-only in 2026 as noted above.

Before you book
A Maine deep sea trip is one of the few fishing days you can buy where the gear, the license coverage, and the fish-finding all come with the ticket. Match the trip to your crew (party boat for two people, private boat for six), sanity-check the captain with the five questions above, and go in the window that fits your target: groundfish anytime, stripers June through September, tuna after the Fourth of July.
If the offshore prices sting, remember the inshore alternative is nearly free: striped bass run the same beaches those Kennebunkport boats work, and the surf guide covers how to meet them on foot.
Common questions
Do I need a Maine fishing license for a charter trip?
Not if the captain is licensed. Passengers on a boat whose captain holds a valid Maine For-Hire Charter Boat Operator's License are exempt from the saltwater registry, which is why some operators advertise "license included." If you fish salt water on your own, register with Maine DMR first: $1 online, $2 through a license agent.
How much does deep sea fishing cost in Maine?
As of 2026, shared per-person trips run roughly $59 for a three-hour Bar Harbor party boat to $240 for a full day out of Boothbay. Private six-passenger boats run about $550 to $795 for a half day inshore and $895 to $1,440 for six to eight hours offshore. Shark and tuna trips start around $750 to $1,350 per boat.
Can you still catch cod in Maine?
Barely, and only in a narrow window. The Gulf of Maine recreational season is September 1 to October 31, one fish per day at a 23-inch minimum. Haddock is the real target on Maine groundfish trips, with a 15-fish daily limit at 17 inches. Be suspicious of any boat promising coolers of cod in July.
What months are best for a Maine charter?
The core season runs May through October. Groundfish (haddock, pollock, cusk) hold up all season, stripers show inshore around June and fish well into September, and shark and bluefin peak mid-summer through early fall. Shoulder trips exist: the Bunny Clark starts April 14 in 2026, and Charger in Boothbay advertises April through December.
Do you keep your fish, and what happens with tuna?
On groundfish trips, yes. Most private boats include filleting and bagging; Teazer in South Portland lists it on their groundfish rates. Bluefin are different: on charter boats, a tuna over 73 inches typically becomes the boat's property under federal HMS charter rules, which the Liveliner states plainly on its rate page. Ask before you book if that matters to you.
What is the difference between a charter boat and a head boat?
Maine DMR draws the line at capacity: charter boats carry six or fewer passengers, head boats carry seven or more. On a head boat you pay per person and share the rail; on a charter you buy the whole boat. For groups of four or more, the private boat often works out cheaper per person.
