Queston on Fripp Island gps map

I am going to buy Coastal Expeditions map, but wanted to know about this map for my Garmin 54 DV. Its the
Garmin Bluechart G2 - HXUS039R

I will fish off Fripp Island and other areas close to that region. I mainly shallow water fish but might do some local reefs not to far from shore, maybe 5 to 8 miles If not this map, can someone recommend a Lowrance map to the region. The above map seems like a good buy at $75

At this time I have what is called Walleye style boat up north, its Ranger 1850 with 4 stroke 150 Yamaha. Is this a good boat for inshore and some off shore fishing on a good day? I have not visited the area yet, hope to do so before Dec of this year.

You can comment on other maps. I also have Lowrance HDS 5 at dash. I will not get to Fripp until Dec now, just found out I need total knee replacement. I have tried to go a different route, but no luck. I will get a new left knee at the Cleveland Clinic Aug. 31
