Penataquit Canal · Bay Shore
More than 180 feet of canal frontage, thirteen private boat slips, three residences and a resort yard — at the end of a cul-de-sac, with Fire Island on the horizon.
Offered at
$2,000,000
The Compound
The owner found this property the way the next one will: by boat. He kept a slip next door, watched this compound come alive each season, and when it came to market he never left. That was more than two decades ago.
What one deed holds here is something the South Shore almost never offers: a legal triplex of three residences, a private thirteen-slip marina on 180-plus feet of bulkheaded canal, and a resort yard — in-ground pool, in-ground hot tub, brick outdoor kitchen, paver patio and palms — at the end of a quiet cul-de-sac, minutes by water from the open Great South Bay.
Nine bedrooms and nine baths in all, five of them private en-suites. The whole first floor of the main house runs as an owner's residence opening to the pool and the water; the suites above, the cottage and the garage apartment earn. It is a vacation estate and an income property refusing to choose — and pulling both off.
From the listing

The Water & The Grounds
The Income
Two independent engines, both running today: a marina that rents by the foot every season, and residences carried by long-standing occupants at legacy rents. Figures below are owner-reported and approximate; the full rent roll and slip roster are shared with qualified buyers.
Gross annual income
±$150K
Marina + residences, as currently run
The marina
±$42K
13 slips by the foot in season, plus winter storage
The residences

Suites, cottage & garage apartment — legacy rents with upside

| Purchase price | $2,000,000 |
| 25% down | $500,000 |
| Est. monthly carry (PITI)* | ±$13,500 |
| Gross income, monthly† | ±$12,500 |
Occupy the entire owner's floor — pool, water, the slip of your choosing — and the existing income offsets nearly the whole cost of carrying it. Raise the legacy rents to market, or open the owner's floor seasonally, and the property can carry itself outright. For qualifying buyers, depreciation on the income portions may shelter income beyond the property itself — ask your tax advisor.

Location
The Penataquit Canal sits between Bay Shore's revived Main Street and the open Great South Bay. The Fire Island ferries leave from a few blocks west; the LIRR is a five-minute drive; and the bay itself starts at the end of your dock.

The short version
The top of Bay Shore trades to $2.25M. None of it came with a marina.
Eight mainland closings at $1.3M and up in the past twelve months put $2,000,000 squarely inside the proven band — and unlike every one of them, this offering arrives with thirteen slips and three income-producing residences attached.
Private Showing
Showings are by appointment. Qualified buyers are walked through the full financials — rent roll, slip roster and carrying-cost models — before or after a private tour. Send a note and you will hear back directly from the listing agent, usually the same day.
