Bring your brunch/lunch. Myrna Hayes 707-656-7852.
Btw: 4,813 people have viewed this post. Do you think 35 will fill the boat so the diesel fuel, which is at an all-time high, can be covered?!!
You’ve been asking and waiting. Here it is! Attached is the flier with details for our upcoming Spring Osprey, Mare Island History and Napa River/Mare Island Strait Boat Trip aboard River Dolphin, with Dolphin Charters and me, Myrna Hayes River Guide.
This is a longer, more lovely trip on the River as we’ll judge the water conditions and potentially go out into the Carquinez Strait a bit on the south side of the Island, then on up-river under the 2 bridges and travel on the Napa River past restored wetlands of the San Pablo Bay Delta, American Canyon, the widest part of the River and actually into the Edgerly Island neighborhood, a charming riverfront grouping of quaint homes and piers, some rather lavishly upgraded, and about at the Brasos Bridge, we’ll turn downbound for our return trip back to Vallejo.
Bring a brunch with your favorite foods and what you’d like to drink. We’ll plan on serving hot coffee, hot water for tea and cold water as is Dolphin Charters’ tradition. This is a very, very rare opportunity. People ask us often and anticipate these river cruises. The boat is a catamaran motor launch. It is Coast guard certified for 47 passengers, but we limit to around 35. River Dolphin features an intimate indoor salon with tables and benches and grand windows for breathtaking views and a bathroom. You may choose to take a seat up top on the sunny, windy deck. Please join us!
To reserve/register call Dolphin Charters directly at 510-527-9622. Leave a message. They DO get back to you. Other questions/details: Dm Myrna Hayes, text/call 707-656-7852.
