Sarca Excel

Hi Marin-Eric.

Rex hear, just thought I would try and clarify a few of your ongoing discussions.

The hoop thingy, I fitted a hoop during development to our anchor design (Super Sarca) for a number of reasons, we wanted an anchor that was multipurpose, it had to have a wide holding area for soft mud, because it was a wide design if upside dow then thats where it stayed unless it was aided with a hoop, we included a pick reef type toe to penetrate harder substrates.


So why did we settle on a hoop rather than a Bruce design.

Bruce, Claw anchors and the type worked well but could on many occasions land upside down in soft mud and the swept up flukes along with the shank would bury upside down and drag.


If you laid them this wasn’t such a problem, in firmer mud it wasn’t a problem, another problem with them on commercial boats is that when deployed in rocks many times they would snap of one fluke on retrieval rendering the anchor useless.


Any way we started out basically following the Bruce concept, concave design and added an extended reef pick type toe, we then whacked a hoop on it to overcome the upside down problem in mud and prevent snapping of a side fluke, we soon learnt why this concept was dropped on the original Bruce anchor, yes Peter Bruce had experimented with this concept and dropped it, there were a couple of standout findings during our development that further influenced us to change to convex design.


When we fitted the hoop to a concave fluke it would most definitely clog in a combination of weed and mud, two, this did create problems in change of tide and setting the anchor in strong wind, this problem has been experienced with many in modern concave designs, believe me it’s out there without being to specific.
No problem with the thick hoops and concave design in clean soft mud, they certainly can bury well down but in general struggle for reasons mentioned in anything other.


And of course the concave has no choice but to bring up all the bait you need to fish when you retrieve them, in some cases they can hold as much as three times the anchors weight in mud. Any way they were our findings during the development of the Super Sarca that was released some 18 years back now.


Marin and Eric.


You are both wright and wrong re your analyses of the various hoop designs, Marin is wright when it comes to his preferred design, the hoop first rights the anchor and then continues to support the toe’s orientation to penetrate, keeping in mind both the main similar concave designs work exactly the same with side entry but with a difference, tip weight, Marin’s design has more than its very similar counterpart.


When it comes to the Super Sarca they are worlds away in design and how they actually work, Eric is right when it comes to the Super Sarca, it does only use the hoop to right itself, as most times it will roll around the hoop landing flat on its fluke presenting it’s turned down toe to the substrate, instant penetration is almost guaranteed in most substrate types, (bedrock excluded) rarely you will see the Super Sarca ever use the hoop to encourage side penetration.


Being of convex design the flukes cutting edges sit unmistaken ably lower than concave, therefore initial set is deeper.

There are skids on concave hoop designs that also to help encourage penetration, the very thick hoop that could restrict the anchor to a shallow set; this I believe is true as there are no videos showing the two similar concave designs burying their hoops out of site.


Super Sarca has the flukes extending just outside of its the hoops perimeter, it is not hollow but solid round, very thin in comparison but is fixed-- reinforced if you like to the top of the shanks rear section via a secondary fluke, this is why if you want to view our videos it is plain to see the hoop although still a restriction, the Super Sarca will and does, in most cases bury it’s hoop completely.


And no, if you want bait you will have to buy it as Super Sarca in most cases because if its convex fluke comes up clean. No extra weight.


Finally Super Sarca is not tip weighted because of its turned down toe, the fluke weight shank and chain is all that is needed to start of a rapid the setting process, unlike the anchors that its’ design is compared to regularly, Super Sarca has another major distinction feature, it is bulk weighted at the rear, as this weight is raised in the setting progress its penetration is boosted in all substrates.

This rear weight also allowed the very first design of a automatic ressetable trip release.


I hope this helps all of you to understand Super Sarca is a totally different breed as to what you are comparing them with.


Who’s got the best anchor, who cares, if a given design works well for you then why fix it.
