Like many motorists, Mary and Dodd Thorpe of Fiddletown whiz through Petaluma en route to other destinations in Sonoma County.
But the Sierra foothills couple passed through town recently at the leisurely pace of about 8 knots — or 9 mph — on a custom-outfitted trawler motoring up the Petaluma River.
The Thorpes were part of an Elderhostel trip organized by Ronn Patterson, a naturalist and seaman who has traveled by boat to Petaluma for 25 years.
His Dolphin Charters trip originated at the Berkeley marina, with the Petaluma River Turning Basin as the destination.
The group debarked for an hourlong stroll to downtown shops and restaurants before heading back down the river.
Patterson’s company runs trips up the Petaluma River, in the San Francisco Bay and the Delta.
He also leads marine-based adventures in Alaska, British Columbia and the Galapagos Islands.
“I came to the Bay Area in 1949 and I’ve learned more in the last two days about the area. You get a different point of view from the water,” said Dodd Thorpe, who spent one day with Patterson on the Petaluma River and one on the San Francisco Bay.
Dolphin Charters offers three-hour Petaluma River tours originating in the Turning Basin, and Patterson hopes to entice residents who don’t have access to the waterway with their own boats.
“I’m passionately interested in people’s awareness of the environment, our home. So often people say, `What’s it good for?”’ said Patterson, taking a break on Delphinus at the Turning Basin dock.
“We come up the river and go very slow and look around. At low tide, it’s like a dinner bell being rung here. You see creatures in the mud.”
The Delphinus is a 50-foot vessel made of cedar and mahogany with a capacity of 32 passengers. The boat is outfitted for tours with seating areas outside and inside the cabin.
It also has a second-story outside deck affording a broad panorama for viewing the sites along the shoreline.
David Yearsley, who has led numerous river trips in his former capacity as Petaluma Riverkeeper, joined the Elderhostel group for part of their journey in March.
“You get a unique perspective from the boat. The second deck allows you to see behind the levees and appreciate the wetlands. It’s a wonderful viewing platform,” said Yearsley, who recently launched Friends of the Petaluma River.
“Ronn is one of the finest naturalists I’ve met. He knows a lot about birds and animal habitat,” Yearsley said.
Patterson’s Petaluma tours for the spring are sold out. Before returning in the fall, he will take the Delphinus to Alaska for weeklong wildlife, scenery and photography journeys.
While the highlights of the Petaluma River are more subtle than the Pacific Northwest’s bounty of bears, glaciers and snowcapped peaks, Patterson is enthusiastic about the virtues — and importance — of southern Sonoma County’s tidal slough.
On the round-trip excursions departing downtown Petaluma, he narrates the river’s history, talking about its economic role transporting goods produced in the area in the late 1800s.
He talks about animals and birds spotted along the riverbanks, and describes plant life in the area.
Although the mudflats along the river’s edge may not be scenic jewels, Patterson views them as critical in the food chain. During past tours , he’s glimpsed deer, river otters, seals and sea lions.
Patterson, a wildlife biologist, naturalist and photographer, acquired his knowledge of the Petaluma River from experience and reading historical accounts from the Petaluma Yacht Club, books about Petaluma and information provided by the Petaluma Chamber of Commerce.
Patterson spent 16 years as chairman of the UC Extension math and science departments, and started the natural environmental studies and photography programs.
He retired to Alaska, where he served as a member of the scientific committee of the International Whaling Commission.
As the Delphinus captain, he puts about 10,000 miles a year on his boat. In October, he’ll return to the Bay Area and resume his winter schedule of short excursions in the San Pablo and Suisun bays, the Delta and Petaluma River.
With the May trips sold out, the next Petaluma tours will be in October and November.
