There was a lot of debate whether these jetties should have been built. It might have been better if they'd gone further north. There's a rock reef here about 12 feet below the surface, so there's no way to ever get a real deep channel here. When you have swells of 6 or 8 feet, you don't have enough water for safe passage. A little farther north, there are no rock reefs and they'd probably have had a safer channel. Reg Pullen
