anchor size

Hi All
I may have missed a mention somewhere on the site but I was wondering what size drift anchor and sea anchor. I found on my first fish trip I was being driven towards the rocks (east) line was drifting (west) out to sea, no breeze to talk of, incoming tide.

Nobody answered

Any small boat or maybe kayak sea anchor/drouge. Although a ski is much heavier than a kayak and catches more wind.

I have seen "small" being up to 6m and thats probably suitable

I use an Anchor at times, A Small Grapnel, then chain about 1.5 times the length of the ski and then 30 meters of rope. The Grapnel is small enough that you can bend the prongs straight if it gets stuck to get it out then straighten them up. It all fits into a 9l bucket which goes in the front storage

I run a buoy on the top of the anchor rope , then I clip a bow rope onto the buoy. I do this for a few reasons, if i need to go in a hurry or go ashore for any reason i can unclip and leave the Berley there/save time etc.A bow rope is connected to the nose of the ski, about 1m out it has a figure 8 loop with a carabiner that clips to the figure 8 loop on the buoy that is connected to the anchor warp. The other end of the bow rope you can lock in the front hatch so you can pull the bouy back and unclip. The bow rope you want to keep as short as possible, cut shorter than the intake grate if you can, floating rope is probably not a bad idea either.

I find a sea anchor is only any use when its wind against tide
