Hi Dennis,
By the photo you posted, the tide looks like it's at half tide.
We have no problems launching or retrieving at half tide but the current is a factor. Our trailer is fully submerse with the water right up to the rims on the car and be aware that the ramp has a drop off at dead low tide, not recommended to use the ramp below half tide.
The marina has a ramp you could use for a fee but it also has a drop off at low tide.
As for fisho's getting their boats wet it's local thing they just don't like to get their feet wet!
When we are retrieving our

they look on with amazement to how far the trailer goes in the water and when the boat is motored onto the trailer and the Admiral hooking up the bow and then driving to the top of the ramp to let out the ballast, the normal comment is "Gee you got some leak there, I get that fixed real quick!" so our kind of boats are not well known down TCB

It's also a local thing for a gallery to gather and sit on the bench's to watch the boats coming and going of an afternoon it's the local entertainment

.
Cheers
