Departure from Bethel Island
Start your journey at Bethel Island, which serves as a great launch point with access to the Sacramento River. Before setting off, ensure that your vessel is equipped with proper safety gear, including life jackets, flares, and a first aid kit. A VHF radio is also essential for communication, particularly as you navigate busier waterways. Check the weather conditions before your departure; the Delta can experience sudden changes.

Key Landmarks and Navigational Aids
As you set out, the Sacramento River will be your main thoroughfare. Keep an eye out for the following navigational aids:

  1. Buoy Markings: Maintain awareness of the colored buoys and markers indicating the channel’s edges. These are critical in keeping you on course and preventing grounding.
  2. Pope Island: As you head downstream, you’ll pass Pope Island. It’s a great spot for a quick break or a picnic if the weather is fine, so keep this in mind as a rest stop.
  3. Mandeville Tip: You’ll reach Mandeville Tip, which is an important point for your navigation as you transition from the river into the delta. Watch for shallow waters to avoid.

Transition Through the Delta
After the Sacramento River, your route will lead you into the delta waterways. The delta can be a maze of channels, requiring attentive navigation. Here are some additional navigational considerations:

Wind Conditions: The Delta area can be windy, which may cause rougher waters. Use this knowledge to adjust your speed and course accordingly.

Shoreline Power Stations: You will encounter various power stations, with significant structures that can aid in orientation—just maintain a safe distance.

Wildlife Protection Areas: As you navigate around the delta, be aware of areas designated for wildlife protection, especially around Turner Cut and the surrounding marsh areas. Take care to follow any posted no-wake zones.

Entering San Francisco Bay
As you approach the San Francisco Bay, be prepared for increased boat traffic. Here, the following points are crucial:

Red Rock Island: A notable landmark visible as you enter the bay. This can be a great location for taking photos and enjoying the view of the San Francisco skyline.

Navigation Aids: Pay close attention to channel markers and lighthouses as you enter, especially the Point Blunt Lighthouse which outlines the entrance to the bay.

Bridge Under Clearance: Be aware of the height clearance for the bridges, especially the San Mateo-Hayward Bridge, which you will navigate beneath depending on your chosen route.
