Owl Harbor Marina

Owl Harbor Marina Voted best marina in the Delta for quiet, family and friends to enjoy all the Delta has to offer. 2 It is truly a remarkable place.

A private gated marina for berthers and their guests to enjoy a unique spot on the water. We are at channel marker 41 on the San Joaquin River and have no bridges to contend with traveling from the Bay Area locations.

Last day of work! 17 years of wonderful friends, memories, and building the best community of boaters ever. Thank you for allowing me to be a part of your lives and family - it has been my greatest pleasure.
Next steps for me - dating my husband, and hanging out at the marina as a tenant.
Excited for Colin and his team to take Owl Harbor to the next stage - it's going to be wonderful. Great minds think alike, obviously we even dress alike at times:). Happy to be a part of it from the other side.
Cheers and see you on the water,
Devery
