If the price listed is a reasonable one, then I offer to pay full price and shipping (after I calculate it). This makes my offer more enticing than some ax-muderer coming to his house and endlessly dickering over the price and then killing him and the rest of his family. Seriously, if the seller agrees to the deal, then I contact them by phone and I can get a pretty good idea what the person is like and if I want to do business. Most that I've dealt with are sailors just trying to sell extra equipment or are getting out of cruising.

Sounds like a good technique.

Hi All:

Although I am sure there will be other responses I would like to take this opportunity to thank you for your comments, once again demonstrating the value of this forum. I have convinced the "Admiral" that this is a good plan so it looks like we will go for it.

Best regards,

Andrew

It is not without tripidation that I dip my toe into the Anchor debate

but I have a question about anchor sizing, specifically for the Rocna. This is not about comparing anchors so much as trying to determine the correct size of anchor.

To get to the point quickly, my question is if a Ronca 20 is sufficient for a 36ft LOA, 11.5' beam sloop with 15,500 lbs displacement in a "typical" East coast and Carribean anchorage? The 20KG is the rated size according to the Rocna charts.

Now the long winded explanation:
Currently, I have a 35lb Kingston Plow which has offered adequate, if not stellar service (we dragged last year in a 35 knot blow albeit in heavy weed after a wind shift). As I am making other changes to my ground tackle I am thinking of also upgrading my anchor and making the plow my backup (I also have a Fortress 16).

Being budget conscious, I am considering going with a Lewmar Delta 44 (which is oversize based on the charts that stipulate 35lb). I can get that locally for about $400. For about $650, I can get a Rocna 20, which is the same weight as the Delta. (BTW. Manson Supreme does not seem to be available in Canada so I would have to order it over the Internet (roughly $500 with shipping and duty from Defender) and I am hesitant to buy things without first seeing them.)

Delta would be more than adequate for the anchoring I that I currently do (inland Great Lakes, mud/sand bottoms, lots of weeds). However, I have (loose) long term plans to head south so I am trying implement solutions that support that goal.

My options are get a Delta now, and upgrade later if required. Or, go with a Rocna20 with the expectation that is a satisfactory for more challenging anchorages. However, I wonder if I should be oversizing it as I did with the Delta, which would put me into the 25KG or 33KG. Upsizing takes it out of my budget comfort zone and thus won't happen now. Which leaves me back with the Delta.

Comments anyone?

Hi Andrew
emai Rocna give them your length and displacement where you want to sail and let them do the rest

Hi Michael

Thank you for your enquiry.

On the information you have provided 28’6” and 7,75lbs(3.5Ton) and taking into consideration of your fully laden cruising weight (by adding an additional 1Ton) and the areas you intend sailing, our recommendation would be a Rocna 10kg which would be more than adequate to cover all your cruising needs, any adverse weather conditions you may encounter and will provide total peace of mind and safety. All Rocna anchors have SHHP classification and its is the size of the Rocna blade area that determines its holding power not the weight. The final decision is of course yours to make.

Our sizing is conservative, intended to provide an anchor adequate for use in all conditions most boaters would ever endure. We base our calculations on 50 knots wind, associated surge, and soft moderate holding bottoms into which it is assumed the anchor has set. This is far in excess of most manufacturers. Naturally there are many variables involved, and in many situations an adequately sized Rocna will easily handle far worse winds than 50 knots. On a weight-for-weight basis, a Rocna is capable of sustaining far greater forces than many other anchor types and out-performs all other anchor types in most real world scenarios. This includes straight-line pull performance. A benefit of this is that when specifying an anchor to handle any given force, a Rocna may be smaller than another type. Conversely, another type will need to be larger in order to offer comparable holding power.

I have also attached contact details for our distributors in the UK and Italy:

If you have any further queries please do not hesitate to contact me.

Martina

Thanks. Yes, I did just that and got a very similar response. It was nice to have a manufacturer reply even if a customized form letter. I set an email, and phone, call to another local anchor manufacturer and never heard back... that was a sale lost for them.

I am picking up my Rocna 20 tomorrow and can't wait to try it out...

Regards,

Andrew

Hi Andrew,

How did it go for you?
