DP is super easy. Bring a hose.. it's worth it.
Caution.. the DP ramp is concrete and ridged down to the water. Go easy when coming back in, (and when launching)... it will rip up the bottom of your yak.. and especially be aware if you have the Hobie sailing rudder and/or turbo fins!
Bait barge is right there, and there's good fishing right around there, inside the harbor. Short kick or paddle, and your outside and there are kelp fields you can play in, and there is open ocean right there also.
Newport.. I've heard you can easiily launch right near the Harbor Patrol Station (I think it's on Shoreline or Bayshore, or something like that?), but parking is a bit tricky. You may need to dump your yak and gear, and then go park on the street. It's not far to the bait barge, but I've never done this launch, so I'm just repeating what I've heard. Good bass and rockfish in that area.. I hear. That's on my summer to-do list.
Post up a report!
