What Griffin Island Offers Anglers

Griffin Island sits in the middle of Boothbay Harbor's outer basin, roughly a mile northeast of the town docks. It's a small, rocky island surrounded by deep water and strong tidal currents—exactly the kind of place where striped bass, mackerel, and pollock stack up to feed. The island itself is private, so you won't be landing there, but the water around it is public and holds fish year-round, with the strongest bite from May through October.

The real draw here is the structure. Rocks and ledges extend outward from the island in all directions, creating a maze of drop-offs and current breaks. When the tide is moving, baitfish get pushed into these channels and bass follow. On slack water, the fishing slows, but the island's position means you're never far from moving water—you just have to know which tide window to target.

Key Takeaways

  • Griffin Island is surrounded by public water with deep channels and rocky structure that hold striped bass, mackerel, and pollock throughout the year.
  • The best fishing happens during moving tides, especially the last two hours of the incoming tide and the first two hours of the outgoing tide.
  • You'll need a boat to reach Griffin Island; there is no shore access, and the nearest launch is the Boothbay Harbor town dock or Linekin Bay Marina.
  • Live mackerel or herring work best for striped bass; jigging with metal spoons or small soft plastics produces mackerel and pollock in deeper water.
  • The island sits in a working harbor with commercial traffic, so stay alert and keep your boat positioned to move quickly if larger vessels approach.

How to Reach Griffin Island by Boat

Launch from the Boothbay Harbor town dock on Oak Street if you have a small trailer or skiff. The ramp is public, well-maintained, and has parking nearby, though it fills fast on summer weekends. Alternatively, Linekin Bay Marina on Linekin Neck Road offers mooring rentals and launch services if you prefer not to trailer. Both put you on the water in under ten minutes of running time to Griffin Island.

Once you're on the water, head northeast from the town docks toward the outer harbor. Griffin Island is visible from the main channel—you can't miss the rocky shoreline and the buoys marking nearby ledges. Position your boat on the eastern or western side of the island depending on the tide direction and wind. The water is deep (20 to 40 feet) close to the rocks, so you don't need to be far offshore to find fish.

Seasonal Patterns and What Bites When

Spring (May through June) brings the first strong run of striped bass moving into the harbor to spawn. They're aggressive and hungry after the winter, and Griffin Island's current-swept water is one of the first places they stop. Live mackerel or herring drifted along the island's edges produces steady action. Expect fish in the 18- to 28-inch range, with occasional larger fish mixed in.

Summer (July through August) is peak season for mackerel and pollock. The stripers are still around, but they're less predictable in the heat. Jigging with small metal spoons or soft plastics in the deeper channels works well for mackerel and pollock. Early morning and late evening are best; midday fishing slows as the water warms. This is also when the harbor gets busiest with recreational traffic, so plan your visit for quieter times if possible.

Fall (September through October) brings another strong bite as striped bass move back through the harbor on their way offshore. The water cools, and the fish are aggressive again. Live bait works best, and the fishing can be excellent from mid-September through early November. By late November, the bite slows as water temperatures drop below 50 degrees.

Winter fishing is possible but inconsistent. Some years the harbor stays open and fish remain; other years ice forms and access becomes difficult. If you do fish in winter, focus on the deeper channels and slack water periods when the fish are less active.

Tackle and Bait That Works

For striped bass, bring live mackerel or herring in the 4- to 6-inch range. Fish them on a simple rig: a 2/0 to 4/0 circle hook, a small barrel swivel, and 20- to 30-pound fluorocarbon leader. Cast or drift along the island's edges and let the current do the work. If you're anchored, keep the bait moving slowly in the current by adjusting your position.

For mackerel and pollock, jigging is faster and more efficient. Use 1/2- to 1-ounce metal spoons or small soft plastics (2 to 3 inches) on a light jig head. Drop them to the bottom in the deeper channels and work them with short, sharp lifts. The bite is often aggressive—you'll feel it immediately. Bring a net; these fish fight hard and can be slippery.

Bring more tackle than you think you'll need. The rocky bottom around Griffin Island eats lures and rigs. Losing a few is normal, so stock extra spoons, jigs, and hooks before you leave the dock.

Tides, Currents, and When to Fish

Tides in Boothbay Harbor run strong, with a range of about 9 feet between high and low. The current around Griffin Island is fastest during the middle two hours of the incoming and outgoing tides. This is when fish feed most actively, and it's your best window to catch them. Slack water (the 20 to 30 minutes between tides) is usually slow.

Check the tide tables for Boothbay Harbor before you leave. Plan your trip to arrive at the island 30 minutes before the tide starts moving. Fish the first two hours of the incoming tide, then move to a different part of the island or switch to jigging as the tide peaks. The outgoing tide is equally productive, especially if the wind is light.

Strong wind can make the water rough and fishing difficult, especially on the exposed eastern side of the island. If the wind is up, fish the western side, which gets some shelter from the mainland. In calm conditions, either side works, but the eastern side often has slightly better current flow.

What to Know About Fishing in a Working Harbor

Boothbay Harbor is a working port with commercial fishing boats, tour boats, and ferry traffic. Stay aware of your surroundings and keep your radio on Channel 16. If a larger vessel is approaching, move your boat out of the channel immediately. Commercial fishermen have the right of way, and they're not expecting a small recreational boat to be in their path.

The area around Griffin Island is also popular with tour boats in summer. These boats follow a predictable route, but they can create wakes that make anchoring difficult. If you're anchored and a tour boat passes, be ready to reset your anchor or move. Most tour operators are professional and will slow down if they see a small fishing boat, but don't count on it.

Respect the private island itself. Do not land on Griffin Island or approach the shore. Fish the water around it only. There are no facilities on the island, and the owners do not welcome visitors.

Frequently Asked Questions

Do I need a fishing license to fish around Griffin Island?

Yes. Maine requires a saltwater fishing license for anyone 16 and older. You can purchase a license online through the Maine Department of Inland Fisheries and Wildlife or at most tackle shops in Boothbay. A seven-day non-resident license is available if you're visiting.

What's the best time of day to fish Griffin Island?

Early morning (sunrise to 9 a.m.) and late evening (4 p.m. to sunset) are most productive, especially in summer when the water warms. The tide matters more than the time of day, though—a moving tide at midday will produce better fishing than slack water at dawn.

Can I fish Griffin Island from shore?

No. The island is surrounded by deep water with no public shore access nearby. You need a boat to reach the fishing grounds. The nearest shore fishing is at the Boothbay Harbor town docks or along the rocks at Linekin Neck, but neither offers the structure and current that Griffin Island provides.

What size striped bass are common around Griffin Island?

Most fish run 18 to 28 inches, which are good eating size and fun on light tackle. Larger fish (30+ inches) are caught regularly but less frequently. Slot-limit regulations apply in Maine, so check current rules before you fish—some size ranges are catch-and-release only.

Is it safe to anchor near Griffin Island?

Yes, but the bottom is rocky and your anchor may not hold well. Use a good anchor and plenty of scope (at least 5:1 ratio of rope to water depth). If you feel the anchor dragging, reset it immediately. Drifting is often easier and more productive than anchoring, especially on moving tides.
