was out there this morning... was nailing sand bass all over on the north shore
. Last i heard GV was NOT closed to boat traffic - but there is only one "official" launch at silverlake marina.
I've been launching from the Murrell park north shore trailhead. Normally it's about .5 mile down to the water... but the water is right up to the gate and it has a parking area. Only good for kayaks - and only if you can roll or carry it past the gate about 10 feet to the water
The submerged road is a ready made ramp.
