How quickly can you get from your dock on Sunset Islands to the sandbar, a marina lunch, or the open ocean? If you boat from Miami Beach, timing your run around bridges, no‑wake zones, and inlet currents can make the difference between a smooth outing and a slog. You want a simple way to plan, plus local route pointers so you protect your boat and safely cruise Biscayne Bay. This guide gives you clear run‑time math, route nuances, and a practical checklist tailored to Sunset Islands.
Where you can go from Sunset Islands
North to Haulover Inlet and sandbar
From Sunset Islands you enter the Intracoastal Waterway (aka Meloy Channel) and head north toward Haulover. This route puts you near the popular Haulover Sandbar and the Haulover Inlet for ocean access. Most of this route is not subject to Manatee Zone restrictions all year round. Note that the Haulover Inlet has a fixed bridge with a clearance of 30-32 feet, and depending on your timing and clearance, you may have to wait for an opening at the two bascule bridges at 79th Street (19-21 feet clearance) and Shepard Broad Causeway (14-16 feet clearance). Expect congestion on Friday afternoons, major holidays and weekends, especially around sandbar anchoring lanes and the inlet approach. The boat traffic really starts to pick up after 11am, especially when conditions are favorable. The approximate distance from the Sunset Islands to the Haulover Inlet is 9 miles, so give yourself 1-1.5 hrs of travel time.
South to Government Cut and Key Biscayne
Running south sets you up for Government Cut and Port Miami, with access to the ocean and the Rickenbacker/Key Biscayne side of the bay. Government Cut is the main southern gateway to the Atlantic and can be busy with commercial traffic and the Fisher Island ferry. Although the distance from the Sunset Islands to Government Cut is only 3 miles, you have to clear the Venetian Island bascule bridge (8-10 feet clearance) and traverse through a couple of Manatee and No Wake zones. The Venetian East bascule bridge opens frequently on the weekends and typically on the half hour between 7am and 7pm.
West across the bay to marinas and flats
Crossing west puts you on mid‑bay shoals and shallow flats, or over to downtown Miami marinas, mangrove islands and the Miami River. Many near‑shore stretches have slow‑speed or no‑wake zones. Always verify depth and anchoring rules, and avoid sensitive seagrass beds.
Estimate your run time
The fastest way to plan is to measure distance in nautical miles along the actual channel and apply a simple formula.
- The run‑time formula: time (hours) = distance (nm) ÷ speed (knots). Multiply hours by 60 for minutes.
- Measure along marked channels on an up‑to‑date nautical chart or chartplotter. Do not measure in a straight line if the route bends or avoids shoals.
- Add time for no‑wake zones, congestion, wind, and current. A 15 to 30 percent buffer is a smart margin.
Practical note: many Biscayne Bay hops from Sunset Islands are short. Depending on your boat, speed underway and restricted zones, a 20 to 30 minute cruise can reach popular sandbars or nearby marinas. Inlet runs usually take longer because you follow marked channels and may time your transit with the tide.
Inlet timing and conditions
Inlets concentrate current. During strong ebb or flood, Haulover and Government Cut can run fast and stand up a sharp chop. Smaller boats often plan for slack tide or a favorable flow.
Wind direction matters, especially when it opposes current near the inlet. Afternoon sea breezes can stack short, steep waves. Build extra time into your plan so you are not rushing your approach.
On busy weekends, give yourself margin for traffic. Expect tighter space and reduced speeds as you merge into the inlet approach lanes.
Route nuances and hazards to avoid
- Follow marked channels. Federal and state channels are buoyed with red and green aids to navigation. Running outside the marks risks grounding on shoals.
- Watch for migrating sandbars and shallow flats. Bars move seasonally, and water can be lower than you expect at the edges of popular anchorages.
- Respect wake and speed rules. Miami Beach and Miami‑Dade enforce slow‑speed and no‑wake zones near shorelines and in canals.
- Mind bridge clearances and canal limits. Verify height, beam, and any municipal restrictions before relying on a private dock.
- Protect seagrass. Do not anchor in seagrass beds. Know local anchoring rules to avoid fines and habitat damage.
Sunset Islands vs. other waterfront enclaves
Sunset Islands sit close to the Intracoastal corridor, so you spend less time winding through interior canals before reaching marked channels. For active boaters, that convenience can make spontaneous runs easier and shorten your repositioning time.
When comparing properties, focus on dock depth at mean low water, dock ownership, the exact channel distance to the Intracoastal, and any tight turns or clearances to reach open water. Confirm state, municipal or deed rules for boat size, riparian rights, use, maintenance, canal rules and regulations.
An often overlooked factor is to consider exposure to wakes from nearby traffic and how local no‑wake buffers protect your seawall. If ocean access is a priority, think about inlet timing at various tidal states and whether your dock is usable in seasonal low water. For long‑term value, verify survey depths, permits, and the condition of seawalls and pilings.
When to hire a local captain
If you are new to Miami Beach waters or plan your first inlet day, a local captain can help you choose the right tide window, read the inlet, and practice safe approaches. The same goes for first‑time visits to crowded sandbars or unfamiliar marinas.
A few hours of local knowledge can save you time and protect your boat, especially on windy afternoons or holiday weekends.

FAQs
How long from Sunset Islands to Haulover Sandbar?
- Measure the channel distance on your chart, divide by your cruising speed, then add 10 to 20 percent for no‑wake zones, congestion, and anchoring.
Which inlet is easier for small boats near Miami Beach?
- Both inlets have their own distinct challenges. However, the Haulover Inlet can be more challenging to navigate as it is much narrower than Government Cut. Pay close attention to the tidal flows, boat traffic and prevailing winds. Plan for slack or favorable tide and seek local advice before your first transit.
Are there restricted anchoring or seagrass zones in Biscayne Bay?
- Yes. Biscayne Bay has protected areas and local anchoring rules. Avoid seagrass beds and verify permitted areas to prevent fines and environmental damage.
What speeds should I expect inside the bay near Sunset Islands?
- Expect slow‑speed or no‑wake zones near shorelines, canals and bridges. You can often run faster through the Meloy Channel (east), but always follow posted limits and local enforcement.
