Some campers are also available to rent or if you are bringing a motor home, Fenwick Marina has semi primitive lodging and primitive. Wild Wings has 2 transient lots. Book camping ahead to reserve a spot. Wakina has all the main points down pretty good. I agree on staying further west which is close to rocky shoreline and the reefs are close compared to Catawba Isl. Most hair jigs have stingers but not all brands do. I use " Killer" brand jigs, my pref. I have more purple , black, green, white, black/purple in the same weights as Wakina mentioned. Take minnows, big ones early jig season. Braid line with a 15-20 inch mono leader tied to jig of flourocarbon line. I use 17 Vanish. Early April can start 1/4 mile offshore maybe 9-13 ft. Study a map of the reefs so you know where they are and how shallow they get, long points, drop offs, shallow flats on a reefs and slow tapers coming off of a reef. As in last season, you may be able to jig fish till the middle of May this year. You want to move the boat slow over fish or some even anchor very early month acting as if you are still on the ice. Most average days I throw a 3/4 oz black/purple jig with a minnow. There are days when a minnow is not needed but take them. Dont just drag the jig, keep it hopping so you dont get snagged in the rocks n muscles. The walleye mostly take the jig on the drop/fall to control the jig on the fall as you may feel the change when it hits. Some people dont feel the bite on the fall and when they lift the rod again its heavy.
Watch your depth when you catch a couple fish real quick. Alot of days its all 13.5 feet or 9 ft or whatever or while you are going across a point of a reef.
April is hardy fishermans time to fish, have fun and be safe !
