Diving atPC-1174 (United States)
Originally a Patrol Craft, PC-1174 was deliberately scuttled in 1968, the same year as the luxury yacht Mizpah. This vessel now forms a critical component of Palm Beach's 'Corridor' wreck site, situated directly off the Lake Worth Inlet. Its historical significance lies in its contribution to one of the region's earliest artificial reefs, though time and storm activity have significantly altered its original form.
Tonight's objective overview for PC-1174 shows an air temperature of 30.5°C. The measured surface conditions include wave heights around 0.6 m. This environmental data is logged for the close of the day.
Dive Site Location & Key Facts
Everything you need to know about this dive site.
Dive Site Overview
The topography of PC-1174 is characterized by its fragmented state, resting in close proximity to the Mizpah wreck. It's part of a compelling cluster of five wrecks known as 'The Corridor,' which can often be explored within a single extended drift dive.
Diver accounts indicate the PC-1174 has broken into several pieces over time, with its largest section now lying beneath the bow of the Mizpah. Another significant portion of the PC-1174 is positioned approximately 12 meters (40 ft) further north. While the Mizpah itself is largely a flattened hulk due to past tropical storms, the scattered remnants of PC-1174 continue to provide structure and habitat.
This site is generally within recreational diving limits, often incorporating shallower sections on the lee side of structures to conserve gas during drift dives along the interconnected wrecks.

Optimal conditions expected
Current conditions near PC-1174 show 30° air, 29° sea temperature, 0.3 m waves, and 21 km/h wind. Forecast data is refreshed regularly to ensure accuracy.
Best Time to Dive
For optimal visibility at PC-1174, the months from June through August generally present the most favorable conditions. During this period, average wave heights are significantly lower, ranging from 0.5 to 0.9 meters, and wind speeds are milder, typically between 14 to 17 km/h (9 to 11 mph). These calmer surface conditions tend to enhance underwater clarity and make for more comfortable boat rides. Air temperatures during these months are at their warmest, averaging between 26°C and 28°C (79°F and 82°F), with moderate rainfall that usually doesn't impact deeper dive site visibility. Conversely, October and April often see increased wave action, which can sometimes reduce visibility, leading to a moderate dive score for those periods.

Dive Experience & Conditions
Diving the PC-1174 is intrinsically linked to the dynamic current conditions prevalent in this area, which sits in close proximity to the Gulf Stream. Currents can fluctuate considerably, ranging from negligible to strong, influencing how the site is best approached. Given these variable currents, deploying a fixed downline directly to the wreck is often impractical. Instead, divers commonly experience exhilarating drift dives, with some describing the entry as a 'perfect drop, like an elevator ride.' This allows for efficient navigation along 'The Corridor' of wrecks, where divers can utilize the currents to traverse between the PC-1174 and neighboring structures like the Mizpah and Anna Celica. Adapting to these drift conditions is a key aspect of the dive experience here.
Dive Difficulty & Safety Guidelines
When planning a dive at PC-1174, divers must be prepared for potentially strong and variable currents. The proximity to the Gulf Stream means conditions can change rapidly; therefore, drift diving techniques and proper surface signaling equipment are essential. While the PC-1174 is broken into several pieces, minimizing overhead environments, divers should still exercise caution around any unstable wreck components. Staying aware of your dive buddy and maintaining situational awareness regarding current direction and strength are critical for a safe experience at this site.

Marine Life at PC-1174
Even in its fragmented state, PC-1174 provides an important habitat within the underwater landscape. Divers frequently encounter impressive Goliath groupers, including a notable resident known as Braveheart, often found near the Mizpah and PC-1174 wrecks. These large fish may approach divers, posing for photographs. Nurse sharks are also known to patrol the seafloor surrounding the wreck pieces. Additionally, the broader 'Corridor' area, including a nearby concrete debris pile from the former Blue Heron Bridge, acts as a sanctuary, attracting a diversity of marine life.
