What is "BB" chain?
Maybe he decides to go with G-4 chain to save 20% in weight and is willing to pay the price over BBB.
Maybe we should do the math? I would want an all chain #1, G-4 5/16" minimum, 150', 50lb Spade type anchor, Same type anchor for #2. That is 100 lbs of chain + 50lbs of anchor for his #2 = 150 lbs on the bow.
The #1 would be 150 lbs of G-4 chain + 50lb anchor =200 lbs on the bow.
All up, his ground tackle would be more like 300lbs. That is a lot of weight to put on the very end of a 35' light displacement cruiser.
