our CQR just lies on its side on the deck, which is painted with ordinary Interdeck. It's shaft is tied not very tightly to the Port side cleat.
It hasnt done anything to the deck in over ten years
so I guess it wasnt worth finding those little plastic things which would be disintegrating by now.
Mine is held by ties and lifted from the deck on teak scraps, suitable carved. the shank has a circular pad with a cutout for the shackle. I've seen the plastic ones and one of my clubmates had his supplied with the anchor. The bronze one's look the Biz but whether they are any more effective than my scrap timber is anyone's guess.
Likewise - but hacked out out of a lump of Iroko. Another block under the bar between the flukes and a couple of 16" heavy duty bungees over the top. Total materials / parts cost about £10.
OK ... few years on deck is not so pristine ... but anchor and chocks still same !!
When I bought them for a previous boat - I got them from Alladins Cave at Swanwick ...
But seriously - a block of softwood such as pine etc. and a file / small saw / knife and sand-paper would see a few "personalised" blocks knocked up easily ... The old trick of a flat piece and then two cut pieces epoxied into position for the fluke tip to sit in ... and similar for the rest ?
a) no marina can measure you with anchor increasing into next price bracket - happened to 2 boats I know.
b) It's neater
c) No anchor sticking over pontoon edge to catch me when I come staggering back from the pub !!
Disadvantage to deck stowage ... handling it back out to launch !
