Depends on the paint you used (ablative or hard) and how much growth of gunk you have where you keep your boat. LA harbor is big so no doubt there will be quite a bit of variation in what grows where. If an ablative paint, monthly cleaning probably is too much, and probably won't be necessary. If a hard paint, monthly cleaning should be fine.
