Hiring someone to work on your boat here

Based on what the harbor requires of vendors, ask your provider for:

  • Their Marina approval + signed Premises Access Agreement (current, not expired).
  • A current certificate of insurance on file with the harbor office.
  • Their local business license number.

Marinas these rules cover

What we looked for and didn't find

  • Slip rates and liveaboard rules (not in the Wharfage Rules).
  • A City of San Diego marine-vendor or hull-cleaning permit for Mission Bay: none found.

“Not found” means it isn't in the public pages we read, not that no rule exists.
