Is the Cantius 46 ready for the Stuart–Fort Lauderdale ICW run?
| Requirement | Spec | ICW Condition | Status |
|---|---|---|---|
| Draft clearance | 3'6" loaded | ICW channel: 6–12 ft (except Jupiter MM 1004: 3.3 ft MLLW) | Caution at Jupiter |
| Air draft / bridge clearance | ~14'3" | Lowest bridges: 9–14 ft closed (openings available) | OK — request openings |
| LOA for bridge openings | 46'11" | All bridges accommodate vessels to 100+ ft | OK |
| Beam for channel width | 14'9" | ICW channel: 100+ ft wide throughout | OK |
| VHF radio | Required | All bridges on VHF Ch. 09 | Verify Working |
| Fuel range | 358 gal / ~70 gal burn for ICW | 80% reserve remaining at destination | Excellent |
| Maneuverability | IPS joystick | Tight bridge approaches, cross-currents | Excellent |
| Wake profile | Planing hull | No-wake zones require discipline | Mind your wake |
Verdict: The Cantius 46 is well-suited for the ICW. Your IPS joystick makes bridge approaches easy. Only concern: Jupiter Inlet crossing at MM 1004 with severe shoaling. Use the inlet bypass route or transit at high tide.
Awareness items ranked by severity
ICW channel has shoaled to <3.3 ft MLLW (Jan 2025 USACE survey). Your 3.5-ft draft WILL NOT CLEAR at low tide. Use the "Bob423" inlet bypass: exit Jupiter Inlet briefly, 180° turn, re-enter ICW south of shoaling (8.0 ft MLLW). No dredging planned. Transit at mid-to-high tide for safety.
Clocks spring forward at 2 AM on March 9. You lose 1 hour. Set alarms the night before. All tide times listed here are EDT. A 7.5–9 hour transit means you may arrive near sunset (~7:25 PM) if delayed significantly.
Brightline train bridge is normally open but closes unpredictably for train crossings. Cannot be closed >50 min/hr. Check bridgeschedule.com app before departure. Could delay departure 5–15 min.
Flagler Memorial, Royal Park, and Southern Blvd bridges are close together (MM 1021–1024). New 2025 schedule reduces peak-hour openings to once/hour. Arrive at this cluster between 9:30 AM and 4:00 PM to avoid peak restrictions.
Flood tide currents up to 5–6 knots past the Hillsboro Blvd bridge. Strong lateral set can push vessel off channel. Slow down, maintain channel center, compensate for set.
Manufacturer spec: 14'3". Some sources list 14'9". Bridges at 15 ft clearance will be VERY TIGHT. Measure your actual air draft with antennas/equipment. At high tide, bridge clearances decrease. Consider retracting or folding any antennas.
November 15 – March 31 manatee protection zones are in effect. Adds 1.5–2.5 hours to transit. Factor into your timeline. Watch for manatees and comply with posted speeds.
Monday is a weekday — regular weekday schedules apply. Less recreational traffic than weekends. However, seasonal restrictions (Nov–May) are in effect for several bridges.
Complete before casting off at 0800
Take the ICW. Depart Sunset Bay Marina at 0800, run the full Intracoastal Waterway south through Jupiter, Palm Beach, Boca Raton, Pompano Beach, and into Fort Lauderdale. Total distance ~73 statute miles with 29 bridges (8–12 requiring openings for your air draft). Expect 7.5–9 hours transit with bridge delays and no-wake zones. ETA ~3:00–4:30 PM.
Fuel burn will be remarkably low — only ~70 gallons — because ICW speeds average 10–18 knots between slow zones. Your 358-gallon tank leaves 80% reserves at arrival. Weather is perfect (E 5–10 kt, fair). Bring lunch aboard or stop at a waterfront restaurant along the way.

ICW transit uses much less fuel than offshore — mixed speeds with frequent slow zones
| Mode | Speed | GPH | Est. Time | Fuel Used |
|---|---|---|---|---|
| No-wake / idle | 5–6 kts | 2.3 | ~2.5 hrs | ~6 gal |
| Bridge approach/wait (idle) | 0–3 kts | 2.3 | ~2.0 hrs | ~5 gal |
| Slow cruise | 8–10 kts | ~7 | ~2.0 hrs | ~14 gal |
| Open ICW cruise | 16–20 kts | ~22 | ~2.0 hrs | ~44 gal |
| Total | Mixed | — | ~8.5 hrs | ~69 gal |
If you plan to continue to Freeport on March 10 (~82 NM at 35 GPH = ~110 gal), you will have ample fuel. Top off in Fort Lauderdale before the crossing if desired.

There are zero locks on the AICW between Stuart and Fort Lauderdale. The only locks in the greater South Florida waterway system are on the Okeechobee Waterway (OWW), which heads west from Stuart toward Lake Okeechobee and Fort Myers. Your southbound ICW route has bridges only — no locks.
Located 15.1 statute miles west of the AICW junction on the Okeechobee Waterway. Not on your route, but useful if you ever head west.

Draft-aware guidance for 3'6" loaded draft
USACE Survey (Jan 30, 2025): ICW channel at Jupiter Inlet crossing has shoaled to <3.3 ft MLLW. Your loaded draft of 3'6" will NOT clear at low tide.
No dredging is planned. This workaround is standard practice. Allow 15–20 minutes for the bypass maneuver.
| Location | Depth | Your Draft | Margin | Status |
|---|---|---|---|---|
| ICW channel (general) | 6–12 ft | 3'6" | 2.5–8.5 ft | OK |
| Jupiter Inlet MM 1004 | <3.3 ft MLLW | 3'6" | NEGATIVE | Use Bypass |
| Hillsboro Inlet area | 5–6 ft | 3'6" | 1.5–2.5 ft | Caution |
| LYC approach channel | 5.0–7.0 ft | 3'6" | 1.5–3.5 ft | OK |
| LYC dockside | 5.0–5.5 ft MLW | 3'6" | 1.5–2.0 ft | OK |
March 9, 2026 — SE Florida Verify Day-Of
Excellent day for ICW transit. Light winds, fair skies. Verify at weather.gov/marine.
| Location | High #1 | Low #1 | High #2 | Low #2 |
|---|---|---|---|---|
| Jupiter Inlet | 1:05 AM (2.22 ft) | 6:49 AM (0.49 ft) | 1:03 PM (2.06 ft) | 7:07 PM (0.09 ft) |
| Lake Worth Inlet | 12:46 AM (2.33 ft) | 7:00 AM (0.42 ft) | 12:47 PM (2.25 ft) | 7:20 PM (0.08 ft) |
| Hillsboro Inlet | 12:45 AM (2.29 ft) | 6:57 AM (0.42 ft) | 12:45 PM (2.15 ft) | 7:17 PM (0.10 ft) |
| Port Everglades | 12:39 AM (2.23 ft) | 6:48 AM (0.39 ft) | 12:39 PM (2.09 ft) | 7:08 PM (0.09 ft) |
Jupiter Inlet timing: You'll arrive at Jupiter ~9:40 AM. Tide will be rising from low (6:49 AM). At 9:40 AM, tide will be ~1.3 ft above MLLW. The bypass route (8.0 ft MLLW) gives you 9.3 ft of water — ample clearance for your 3'6" draft.
Waterfront restaurants with dockage for a 46-footer
930 ft courtesy dock right at Sunset Bay. Perfect pre-departure breakfast. Opens 11 AM for lunch.
Tiki restaurant on the ICW near Jupiter Inlet. Dock available — call ahead for 46 ft. Great rum drinks. Arrive ~10:00 AM.
Classic ICW waterfront at PGA Bridge. Pull-up dock. Great for an early lunch ~11:00 AM. Fish dip is legendary.
Full-service marina with slips to 65 ft, 7 ft at low tide. Excellent dockage for Cantius 46. Arrive ~1:30 PM for late lunch.
Upscale waterfront, 180 ft dock. Near destination — arrive ~2:00 PM for a final-stretch lunch before LYC.
Best option is directly on your ICW route
800-ft snorkel trail. Artificial reef, seahorses, octopus, sea turtles, nurse sharks. Depths 5–20 ft. Protected calm water. Boat ramp and dock at Phil Foster Park. Best time: 1 hour before/after high tide. High tide March 9: 12:47 PM. Arrive ~11:00 AM on your timeline — a bit early for peak snorkeling but conditions will be fine on the rising tide.
Monday, March 9, 2026 — after arrival

Monday is the quietest nightlife night. What's open:
Can we go to Freeport tomorrow? Here's the full assessment.
East winds 5–10 knots, seas ~2 feet. No Gulf Stream hazards reported. The Cantius 46 can handle this crossing safely and comfortably. BUT: return by March 11. A front arrives Thursday bringing NE 15–20 kt winds and 4–6 ft seas.
| Date | Wind | Seas | Conditions | Verdict |
|---|---|---|---|---|
| Tue Mar 10 | E 5–10 kt | ~2 ft | Light chop, fair | Go |
| Wed Mar 11 | SE 10–15 kt | ~2 ft | Light chop | Return OK |
| Thu Mar 12 | SE 10–15, becoming S | 2–4 ft | Building | Marginal |
| Fri Mar 13 | NE 15–20 kt | 3–5 ft, occ. 6 | Front arrives | No Go |
Weather window: March 10–11 only. If you stay in Freeport past Wednesday, you could be stuck 2–3 days waiting for the front to pass.
The Cantius 46 is a sport cruiser, not a bluewater vessel. However, for this crossing in these conditions:
Option A (Conservative): Fort Lauderdale → West End (~56 NM) → Clear customs at Old Bahama Bay → Coast east to Freeport (~25 NM). Total ~81 NM but more protected water after West End.
Option B (Direct): Fort Lauderdale → Freeport direct (~82 NM). Steer ~090–095°T to compensate for Gulf Stream. Faster but all open water.
Fuel in Freeport before return. Bahamas fuel is pricier ($6–8/gal) but eliminates fuel anxiety. Depart with full tanks both ways.
