Fishing near Hyannis
Striped bass, bluefish and fluke. Center consoles and bay boats are common.
Where Hyannis boaters launch and cruise
Hyannis Harbor and Lewis Bay open onto Nantucket Sound, and the Centerville River lies to the west. Marinas and ferry terminals line the harbor.
Nantucket Sound is relatively shallow, with shoals that require careful navigation, and the water warms more than Cape Cod Bay. The Kennedy Compound in Hyannis Port is a well-known landmark from the water. Lewis Bay is a protected area for small boats, and the town’s public ramps are busy on summer weekends with trailer boaters heading out to the sound. Bass River, Barnstable Harbor and the Cape’s many kettle ponds give trailer boaters plenty of other options within a short drive.
Recommended setups
Twin-engine and offshore boats
If you run twin or triple outboards, replace cranking batteries as a matched set. AGM batteries in Group 31 size are a dependable starting choice for big outboards, and many Hyannis owners add a lithium house battery so the electronics never touch starting power. Check your engine maker’s cranking amp requirement before you choose.
Flats skiffs and bay boats
Most bay boats on Hyannis Harbor run a 24V or 36V bow-mount trolling motor plus a separate cranking battery for the outboard. A 36V lithium bank, such as a single EPOCH 36V or Interstate 36V battery, replaces three Group 27 or 31 lead-acid batteries and drops well over 100 pounds from the stern, which helps a skiff float shallower. Keep the cranking battery separate so a long day on the trolling motor never leaves you unable to start.
Pontoons and tritoons
Most pontoons on Hyannis Harbor run a single 12V battery for the engine, stereo, lights and maybe a small trolling motor. That works until the music runs through a long afternoon at anchor. A dual-purpose battery, AGM or lithium, handles both cranking and accessory loads better, and a second battery on a switch keeps starting power in reserve.
Keeping batteries healthy in Massachusetts
Boats are hauled in winter. Store batteries properly.
The boating season is short, so it pays to have batteries ready in spring. Test them before launch, and replace any that won’t hold a charge.
New England and Long Island boats are usually hauled for winter. Charge batteries fully before storage, and keep lead-acid batteries on a maintainer or remove them. A discharged lead-acid battery can freeze and crack.

FAQ
Do I need a heated lithium battery for Hyannis?
Only if you plan to charge in freezing weather. Standard lithium batteries should not be charged below 32°F. Batteries with internal heating, like several EPOCH models and the Dakota Lithium DL+ 135Ah, warm themselves before charging. For normal spring-to-fall use with winter storage, a standard lithium battery is fine.
How do lead-acid batteries ship?
Lead-acid and AGM batteries ship free by curbside truck freight to the lower 48, the same as lithium.
Do chargers and accessories ship free?
Chargers, accessories and lithium batteries of $150 or less ship free when your cart subtotal is $150 or more. Otherwise a flat shipping rate applies, shown at checkout.
Can you ship to my marina?
We can ship to most addresses, but marinas with restricted access or no way to receive freight may cost extra or need special arrangements. A home or business address is usually easiest. Contact us before you order if you want to ship to a marina.
