Hilbre is back in the water at San Carlos, Sonora and headed to Topolobampo late next week. We made a few changes to the ground tackle. Swapped out the 40 lb SAS/CQR for a 44 lb Rocna. I know there have been lots of discussion on Rocnas and mine was made in China in May this year. Will let you know how it works out for us.

John, could you please post a photo of how your 44lb Rocna rests in the bow roller and show how much clearance there is between the anchor and the fiberglass? That would be very helpful. Thanks.

Hi John,
Wishing you the very best cruising in the SoC. Our plans are to retire and be there in the next few years. I am very interested to hear how you prepared Hilbre for the cruise, what you wished you should have done before you departed and now that you are cruising, what upgrades you would like to do.
Please keep us all informed as your cruise progresses on how onboard equipment is performing and your thoughts on the Sea's best cruising and anchoring grounds.
Envious,
Tony

I second Larry's request - some photos would be great. I've been thinking of replacing my 35 lb. CQR for a Rocna...

Looks like I will need to increase the Bail height by about an inch to snug the anchor home. The tip should be nicely clear of the bow. Out Bail hunting and may have to get one machined in Guaymas. Apparently there is a good marine shop there called Hernandez Brothers. I just have to find them. I will send front and side pictures when the work is completed.

Love to hear how you like this anchor in different conditions and bottom composition.

We are headed to Isla Isabella, San Blas and Chacala. Then on south to at least Mazanillo. I had two new bails fabricated in Mazatlan for the Rocna and there are pictures and a description of this installation under Tech Notes/Reference/C36 Anchor Survey from Larry.
We have enjoyed the sights, sounds and foods of Mazatlan but it is time to move on. Anyone heading to the Sea of Cortez should not pass up the opportunity to stay at the new Marina in Topolobampo and do the "El Chepe" train up to Copper Canyon from Los Mochis or better yet, from El Fuerte. What a great ride and spectacular views.

In response to earlier questions, the Rocna lived up to its reputation. Anchored in 20' in San Evaristo, with 10 other boats it was quite crowded as a strong Coromuel (night-time west wind) was expected, so could not use more than 4:1 scope-all chain. When it hit, we swung to 26' of water so now down to barely 3.5:1
Sat up all night with lots of wind steady at mid 20's and frequent gusts to high 30's. Highest was 42 Knots. Anchor held so well I had to work hard to break it out the next morning. Ground was sand over a bed of dirt/firm mud, admittedly good holding. One boat (38' Island Packet) next to me did drag almost onto the reef 300 yards in our lee. Moonless night, crowded anchorage with wind, they managed to find another spot and anchor again. Give me a Rocna anytime!
We are in San Carlos, MX at the end of season two cruising Mexico. 1,000 NM, many marinas, anchorages and lots of new cruising friends. The C36 continues to amaze me, Hilbre has seen us through all sorts of conditions without a whimper. What a great boat we have!

Hi, John. I guess I am going to be "one of THOSE guys" by telling you that unless your anchor dragged, your scope did not change at all. What determines the scope is the vertical distance between the anchor and the rode's attachment to the bow. How much water is under your boat makes no difference at all.
I used this example on one of the quizzes I designed for a course I taught, and, yes, it is a tricky thing to wrap your head around at first.
The very crude sketch shows the boat in two different depths, but the vertical distance to the anchor is the same and the angle of the rode to the anchor is the same.

John,
What length and size chain are you using on the Rocna?
Thanks,

I guess I would have failed the course! You are correct, sometimes you forget your Geometry.:D

Tony:
120 feet of 3/8 HT backed up by 220 feet of rode. In the Baja, most anchoring is in the 25-35 foot depth. I like to lay out all the chain and some rode as a spring but once in a while I have to resort to using a chain hook.

Very true, Duane. Having said that, when the boat is over the high ground it would have to drag the anchor uphill, the angle of 'uplift' on the anchor stock will be less, so the effect is [I]similar [/I]to having more scope. Mind you in this situation you likely have a [I]lee shore[/I] so you want all the holding advantage you can get! ;)
