It's tight and parking can be an issue, but I have launched our 20' ski/fish there. It is steep also so 4WD to pull something heavy back out is probably best. I'd be more concerned about parking than anything.
I launch my 18 ft pontoon several times a week. Need4x4 to get out. Fished today, found lots of rainbowa in front of Catarac creek about 10 ft down. Macks were awsome until this front came in. Should pick up soon. About 55 ft down. Largest 7 lbs but still fun.
