Chain with Nylon rode bridal to smothout tugging & surging
I have a Full Displacement Kadey-Krogen 42 -- Heavyer boat than yours & I am on the west coast.
2 anchors on bow --- I have
all chain on both. 275 feet chain on each side -- port side is 3/8" HT & Starboard is 5/16" HT.
---- I run dual, but different style anchors on the bow -- different types for different holding ground.
I run one anchor as a Bruce on port side & the other is an Ultra Plough on Starboard side.
On Chain Bitter end is an additional 50 feet of 5/8 spliced to end link of chain & secured to the boat in chain locker, just in case I need to cut it & run in storm conditions.
if your concerned about the weight in the bow, go with G-4 High Test in a smaller chain link size.
Nylon rode is fine for a lunch hook & as a snubbing bridal.
However, Not recommended for overnight sleeping.
Particularly in the area of the Bahamas where your going.
All chain with a bridal of nylon rode to smooth out the tugging & surging will be well worth the investment.
you won't regret it.
Have fun.
