Thanks, yes as you guessed, no room for the hardware...Here is the type of anchor lock I have that works very well with 15 kg Rocna. Your 26's bow may not have the space for such hardware.
Instead of deploying and retrieving the anchor and rode under the roller furling drum and the foremost bow stanchion, use the space between the 1st and 2nd bow stanchions but route the anchor rode through the anchor roller and secure at the bow cleat. I had to do that on a Sabre 28 which comes from factory without a bow roller.
I will try your first and second stanchions suggestion.
I still need to come up with a more permanent solution that my passengers or girlfriend can easily drop the anchor.
