Manson Supreme Size?

My guess would be because windage increases with boat size.

Sorry should have read the above post more closely

I'd look at windage and weight as bigger factors than length. If you have a big full cockpit enclosure, a flybridge, or a multihull your windage will add significantly to anchor pull. (Weight only comes into play when considering dynamic snatch loads from veering and waves.)

At any rate, the OP should consider adding a windlass if you can't man-handle the weight of the right-sized anchor for your boat. Yes it's expensive and a major modification, but it's cheaper than fixing/replacing your boat if you drag aground. You'll sleep better too.

(edit: Yes go one size up, and don't even consider anything less than 25# for your size boat. If you're cruising you need to be able to hold in storms. JMHO)

I have a 32 ft Hunter, about 10,000 lbs. I went with the 35 lb Manson Supreme, 50 ft of chain, and 250 ft of rode, all pulled up with a windlass.

Very satisfied, it holds very well, we were in Galveston bay, had anchored in 7 ft of water, (we draw 5). Wind was at 10-15 knts, predicted to drop to about 5 in 2 hours, at about 1 hour wind speed went to 37+ knts, and in a different direction, so of course we moved a bit. Either we did not drag, or the anchor immediately reset. BTW, at the 2 hour point, wind speed was down to 5 knots, so the prediction was correct, not good enough, but it was still correct.

My recommendation, go big & get enough chain so you can stay where you want.

I have a Catalina 310 at about 15,000 lbs when cruising. I have the 35 with 30 feet of chain. The only thing I would change is more chain for chafe reasons.

Yepper. Thanks. I started to call the factory but stopped when I realized that my boat would have been the extreme application for the 15# so it really is a no brainer to go for the 25 +.

Sleeping on it, I think I need a windlass. Re-anchoring in the middle of the night is no fun, as we all know. So a 35 is a real possibility.

The local We$t has a 35# Delta for $140 but the Made in China sticker put me off.

With all this new stuff, I'll probably be barred from the $500 a month threads.

However, I sure have cold beer, and I kinda like the hum of the Air X.

And yes, I take back all those comments about fancy stuff.

I got into anchoring years ago with my Hunter 30. At that time before our harbors filled with ell grass, I used a 33# Bruce with 25-30" of 3/8 chain. Later I upgraded it to a 44#.

My experience may be helpful to you and because I like to sleep at night, I would go oversized with the 35 but you do need a bow roller AND I DON'T RECOMMEND A DELTA! Been there, done that! They plow and over time your boat could be on the beach.

But getting back to my Hunter. I installed a bow roller that fit the Bruce and a roller makes a huge difference. I used to sit in the anchor locker, give hand signals to Wifey who would power the boat forward removing the load from the road. I could easily retrieve even my 44# Bruce with the chain, no problems at all. I just sat there and pulled backwards retrieving the chain. Always had to use the boat's engine to free the anchor and then simply haul it onboard, secure it and we were done.

I do have a windlass with my 40 Silverton which uses an 80#MS. If I had a 30-35' sailboat, I would try it without a windlass.

Thanks Foggy. All good points. I wasn't interested in the Delta but wondered why it was half price. I'm going with a Manson.

All good points. as I write this, I'm anchored at Avila Beach in Southern Ca. on my way south (using pirated Wifi by the way) I have a Hallberg Rassy 35. Last time on the scales was 17,000 lbs. That's pretty much loaded. It has the classic windshield and is of medium freeboard/windage. I choose a Rocna 44 pounder. I'm quite impressed with it. I haven't experienced anything more than 25kts of wind but I can tell you it sets instantly. I went one size up and sleep well.
I'm amazed at the people who have become adapted to dragging as a part of life. I don't think that has to be.

We have a Manson Supreme 35 # on our 36' Hunter. I'm a noob really, having left Kemah, Tx. about a year ago. We have anchored in everything, from Galveston, to Louisiana, to Mississippi, to Alabama, to Florida, to the Exumas, and now in Georgia. The Manson has always set, despite my lack of experience in the beginning. Fortunately, we have never dragged, even with 50 + knots during a thunderstorm in George Town, Bahamas, this past June. Maybe just luck, maybe a really good anchor. We have 100' 5/16 HT chain, plus 120' of rode. I think the 35# was recommended for our 36', and I didn't go larger. I also do not have a windlass, and you don't need one probably. Hell, I'm 61 years old, and 135 lbs.

Hey Ralph,

Long time no post, so glad to hear that it is still happening for you guys, and that the Manson is working well.

Cheers,

Jim
