Dive Site Location & Key Facts
Everything you need to know about this dive site.
Dive Site Overview
The Captain Dan offers a compelling dive experience, distinct for its structural integrity and historical significance as an artificial reef. Originally commissioned as the US Coast Guard Tender "Hollyhock" in 1937, this 175-foot vessel was intentionally sunk in February 1990, becoming a part of the Rodeo Reef program.
Today, she rests upright on a sandy bottom at a maximum depth of 35 m (115 ft), with her bow oriented south. The top of its wheelhouse typically sits around 21-24 m (70-80 ft), while the main deck is found closer to 27 m (90 ft). Significant access holes have been prepared throughout the wreck, allowing certified wreck divers to explore internal sections safely.
Its sheer size and the vertical orientation create dramatic visual appeal underwater, offering a glimpse into its past service. Penetration dives require specific training, making this a site primarily for advanced divers seeking depth and exploration.

Best Time to Dive
For an optimal experience on the Captain Dan, targeting the warmer months from May through September generally presents the most favorable conditions. During this period, the air temperatures are reliably warm, averaging between 26°C (79°F) and 28°C (82°F). Wave heights also tend to be at their lowest, often less than 0.8 meters, which contributes to calmer surface conditions for boat travel and entry. Rainfall, while variable, sees its highest averages in these months, particularly in July, August, and September, which might occasionally affect visibility. Conversely, the cooler months, specifically January and February, still offer good diving with air temperatures around 19-20°C (66-68°F), though wave heights can be noticeably larger, averaging over 1.2 meters. Dive scores reflect "Good" conditions for much of the year, dipping to "Moderate" in March and April due to slightly increased winds and variable wave patterns.

Dive Experience & Conditions
Diving the Captain Dan demands an Advanced Open Water certification or equivalent experience, primarily due to the wreck's depth and the potential for strong currents. Entering the water, divers often descend directly onto the wreck, which stands impressively upright. Navigating the structure, the top of the wheelhouse provides a good orientation point at about 21-24 meters. Currents around the wreck can be robust, requiring divers to manage their position carefully. For those with appropriate wreck penetration certifications, large access holes offer pathways into the ship's interior. Visibility can vary, but clear conditions often reveal the entire 175-foot length of the vessel. The deeper sections extending to the maximum depth mean bottom times are inherently limited without advanced planning.
Dive Difficulty & Safety Guidelines
Successful diving on the Captain Dan hinges on recognizing its specific environmental challenges and your certification level. Strong currents are a frequently reported factor, posing a risk of divers being swept away from the wreck. Carrying a signaling device, such as an SMB, is therefore highly recommended to aid in surface location should you drift. Due to the significant depth, typically ranging from 24 to 35 meters (80 to 115 ft), gas management and no-decompression limits require careful attention. Wreck penetration, while facilitated by cut-out access points, should only be attempted by divers with specific wreck diver training and appropriate equipment. Planning each dive thoroughly with your buddy and checking local conditions beforehand are crucial for a safe outing.
