Was just on the club launch yesterday with another member who nearly lost their boat, a beautiful J 109, to a Fortress, we did too. Both of these situations were the same, middle of the night wind shifts followed by highish winds. In both cases the Fortress failed to re-set. They hit another boat, this was after being anchored in the same spot for three days, an that saved them from going onto the rocks. The owner of the J has ordered a brand new Spade , we are still using our Rocna....


I still love my Fortress, and they are a GREAT COMPANY THAT STANDS BEHIND THE PRODUCT. Sadly I will now only use it as a stern anchor where I know it can't be put in a situation where we need to relay on it re-setting. We will never again depend on it as a primary in the land of 10-20 foot tides and 360 swings nearly every night at anchor...

I have seen NO DIFFERENCE in performance between the Manson Supreme and the Rocna. They are both excellent performers.. Canada Metals, the new owners of Rocna, are a good company and if you can get one made under their production watch you should be fine.

First experience with my new Rocna...

I actually purchased a Manson Supreme first, a 45#, but I couldn't get it to fit on my roller without some serious modification...it was tooo big anyway without a windlass. So I opted for the Rocna (33#) and got it wet for the first time yesterday. It set on the first attempt and dug in quick, then today it held confidently in a pretty serious thunderstorm with winds in the 40's shifting more than 180 degrees. I have 50' of chain spliced to rope.

Nice job Rocna.

sailingdog If Lewmar makes a 5/16" G43 high-test gypsy for it, yes, you can just swap them out.

Thanks,

The windlass is a Lewmar pro series. I know it comes in two sizes but don't know which it has. If it is the 1/4 can I just change the gypsy for the 5/16th if I want to move up?

Man am I going to have a million questions if I get this boat and bring it home!!

The 15 would be adequate for most usage; go with the 20 if you want to be super conservative, and if the rest of your gear is matched to it (or you're prepared to also upgrade it).

More on the Rocna sizing:
Rocna sizing recommendations (Rocna Knowledge Base)
The cat is a Gemini. 8600 lbs from the factory, so let's say 11k max.
I'll check the rest of the gear. The chain looks really thin looking. Advertised as HT but don't know the size.
I haven't closed on the boat yet.

I'd say that SD's comments above are on target.

An up-to-date list of American resellers is maintained here:

OOPS!

Read the chart wrong. Biggest listed - the 25 (55 lbs)
