realistic. Assume you have appropriate rode. The anchor will cope with
this,
assuming the pull angle is reasonably low.

Just wondered what type of rode would handle this force? On your site, you
recommend the 10Kg anchor for cruising boats up to about 30'. What would
teh corresponding chain/rode dimensions be to match teh anchor strength?

1/2 inch (12mm) 3 strand nylon has a breaking strength of about 7,000
lbs and a Safe Working Load approximately 1/3 of that. Typical anchor
rode for a 30 foot boat would be about 200 ft of 1/2 inch 3 strand,
shackled to 15 or 20 feet of either 1/4 or 5/16 inch chain. That is
enough rode to safely anchor in 30 ft of water.

For a storm anchor I'd use 5/8 inch 3 strand nylon with 5/16 HT chain.

Shackles rated for 2,200 lbs are easy to find.
