What people run and fish for in Mystic
Striped bass, bluefish, fluke and porgies. Sailboats and center consoles are common.
The water around Mystic
The Mystic River runs from the village to Fishers Island Sound and Long Island Sound. The river’s drawbridge in downtown Mystic opens on a schedule for boat traffic. Stonington Harbor lies to the east.
Mystic Seaport Museum preserves historic ships, including the Charles W. Morgan, the last wooden whaleship. Fishers Island Sound is protected and popular for sailing, and Watch Hill, Rhode Island, is a short run to the east. Many Mystic boats are kept at marinas along the river, so batteries spend the season on shore power and need a charger set for their chemistry.
Batteries that fit Mystic boats
Sailboats and cruisers
If your sailboat on the Mystic River uses a lot of power at anchor, lithium is worth a look. It provides more usable capacity per pound and accepts charge faster. Before you switch, check that your alternator, charger and solar controller support lithium.
Twin-engine and offshore boats
Offshore boats depend on their batteries more than any other boat on the Mystic River: radar, sonar, chartplotters, livewells and VHF all draw power while drifting over a ledge. Size your house battery for a full day of electronics with the engines off, and keep it isolated from the cranking batteries with a switch or combiner. A multi-bank onboard charger keeps every battery topped up at the dock.
Bay boats and flats skiffs
For a skiff or bay boat that spends the day poling and creeping along the flats near Fishers Island Sound, trolling motor capacity is the number that matters. Measure your current batteries (group size, voltage and how many) before you order. If you stay with lead-acid, Group 31 deep-cycle batteries give the most runtime per battery; if you move to lithium, one 36V battery wired for your motor makes the system simpler and lighter.
Keeping batteries healthy in Connecticut
Boats are hauled in winter. Charge batteries before storage.
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.
Freight and delivery to CT
- Free lithium freight: lithium batteries over $150 ship free, curbside, to the lower 48.
- Parts and chargers: free shipping when your cart subtotal is $150 or more.
- Lead-acid and AGM: free curbside truck freight to the lower 48, the same as lithium.

- Inside delivery, or hard-to-reach spots like marinas with restricted access, may cost extra, so a home or business address is usually best.
