Greg Marsten's Unda Maris III, Yankee #125, San Francisco, California - updated September 15, 2013  

June 11, 2009. Greg checked in with the following email and photo. Stay tuned for more about Unda Maris III. And click here to go to Unda Maris II.


Thanks for the wealth of information on your site! I have been a proud owner of a Yankee Dolphin since last summer, when I found Dolphin #125 near Sacramento, CA. I spent the summer restoring her, and she's now berthed in San Francisco. Her name is the "Unda Maris III". I've attached a photo.

This isn't my first Dolphin encounter, my dad owned Yankee Dolphin #231 (then Unda Maris II) in Marina Del Rey, but sold her around 1996.

Thanks and keep up the fine work!



August 29, 2009 Greg sent in some additional info about Unda Maris III and a couple of super photos of their main and fore hatch rebuilding project.

Unda Maris III lives at the San Francisco Marina, where you can occasionally see the golden gate bridge in the background! It's a choppy marina, but a great location. I don't have much history for either vessel; I found the current vessel up in the Sacramento Delta and sailed her down to the Bay. Interestingly enough, there was another Dolphin in that marina as well!

I've attached a couple more photos of the work we did on the boat, reworking the hatches out of hardwood. It's my dad's handiwork here, he took the original teak framing and redid the wood slats with an aluminum backing to keep them waterproof. This was apparently a problem, as the original condition we found the hatches had several extra layers of tar paper, caulking, and Boat Board over the original hatches!

Why "Unda Maris"? Well, that's the name we inherited for the original boat, and the whole time we owned her, never thought to look up what it meant. Many years later, I discovered it's a lever on a pipe organ, meaning "waves of the ocean" which is exactly what you feel when you're out on this boat, and decided to continue the tradition!



October 20, 2011. Greg sent in some more pictures of the hatch rebuilding project. We have set up a page in the Technical Section/Repairs for this project. Click here to go there

Dolphin 24.org Technical Staff back at headquarters reviewed the data base and sent an email to a likely suspect.

Hi Greg
It's been a while. I trust all is well with you and Unda Maris III.

My daughter, Nicole, a senior DFI, living in SF got these photos. Is this Unda Maris III? The white life preserver is my clue but the boat has a furler - new?



Yes!! The furler is a few season old and has been a godsend on the bay, especially when its gusting up to 27 kts like it was yesterday. You're making me wish I had some sails up for the photo though  :) Thanks for passing these along!
