What size of anchor rope will I need for a 14ft open displacement(150kg) boat ? 100 ft depth so 300 ft length. already have 4lb anchor and chain. On the sea but close inshore

well 4mm para cord has a breaking strain of 550lb which will lift your boat so certainly hold it at anchor but will cut your hands up trying to pull it up. Therefore the thickness is not really an issue with regards to strength; the compromise is thicker rope takes up more space but is more comfortable on your hands.
The normal answer appears to be use 12mm if pulling the anchor up by hand and 10mm if pulling it up alderney style. I reckon with a lighter boat and small anchor you will find 10mm will be OK.
Don't forget you will need some chain too.

Multiplait rope is a little dearer but nicer on the hands.
as said if hand hauling then 10mm minimum.

I used to have some rope for my boat, dunno what it was but it did not have a memory, was very loose and did not tangle at all, beautiful stuff. It was plaited rope of some description, think it came off my sailing dingy, you could chuck the whole lot into a bucket, and it never ever came out tangled. Was ideal for when space is in short supply as it was very easy to compress down, just a pity I do not know its name. lighty |

But don't forget the trip, and always take a buoy just in case you can't get the bloody thing out.
then at least you can buoy the rope and hopefully talk nicely to someone with a bigger boat who will hook it out for you.
