What is recommended for the right size anchor for the Sandpiper 565, anyone know? Also, should there be a pulley for the topping lift??? Thanks.IP: 129.170.61.173 |

Yes...I have a block/pulley at the mast cap for my topping lift. I'd have to check my Power Squadron books to advise on an anchor...but mine came with a 10 or 15 lb Danforth and a small navy anchor.IP: 156.34.84.144 |

Mine came with a 6 lb Danforth and no chain (not a good thing). Guarranteed to drift I found.So I bought a 10lb Danforth with 6 ft of (way too heavy) chain. What a pain. But that sucker holds pretty well. Its too big for the anchour locker so its stowed at the stern. I think I'll change the chain to a slightly lighter size and make a bow rail mount for it. I also added 6 ft of (reasonable weight) chain to the lighter Danforth. I carry both at the present time for use when anchouring close at beaches. IP: 67.70.4.175 |

I have a 6 and 12 pound anchor, both with at least 8 foot of chain. Never used the 12 pound yet.Sid IP: 67.40.133.135 |

I bought an 11 lb Bruce type anchor for mine. It fits nicely into the anchor locker along with 10 feet of chain and 200 feet of 3/8" nylon rope. The boat came with a small Navy type anchor, that I don't think would have been adequate.
The topping lift on mine just has a D ring riveted through a hole at the top of the mast. I'm not sure if that is the way it came, or if it was something the previous owner did.Richard. IP: 216.86.96.83 |

Shortwave came with a plow type anchor, a 10 lb danforth and a Herreshoff designed (I believe) folding anchor (looks like a navy anchor but it folds up. Each has 12 feet of chain. We have 250 feet of anchor line marked with plastic tags so you can easily tell how much line is out.I've been thinking of cutting the line to have a 150 and 100 foot length which I think would be fine for our small lake. I doubt that most of the boaters on our lake even have an anchor on board. D'Arcy IP: 65.92.114.244 |

I have a mushroom type "lunch" anchor with 50 feet of rode that works for short stops. I have two danforth anchors, small and large, don't know weight, and 200 or 250 feet of 3/8 nylon with about 8 feet of fairly light chain. A recent article in Sail Magazine discused anchors with a different perspective. The article emphasised that it isn't the 20 pounds of anchor that holds the boat, its the bite into the soil that holds the boat, and to maintain a good bite, the rode should pull horizontal, not vertical. That is one major purpose of chain, to hold the rode horizontal. The author went through the mathematics to solve the catenary for an anchor chain and discovered that the normal 5:1 or 7:1 scope is often not sufficient, the vertical component is too great even at 7:1. Now he was trying to hold a boat in 30 knot winds, so 7:1 may be fine for less wind, and I use 5:1 (sometimes less) for lunch stops, but for real severe weather, length of rode is very significant. His recomendation was 100 feet plus 3 times depth. So, in 30 feet of water, use about 190 feet of all anchor rode. By the way, he was modeling all anchor rode, those of us using nylon should actually use MORE length!!
I was very interested in the article because this February I was in a boat anchored overnight in 30 knot wind, we had used 7:1 scope and dragged anchor in the middle of the night. Almost blew into a sea wall. Had we used his formula, we would have had almost twice as much rode out. IP: 67.107.33.106 |

Our Canadian Power & Sail SQuadron courses called for 18.5 feet of anchor chain on a Sandpiper. That is...1 foot of anchor chain for every foot of overall length of boat. This would hold the rode fairly horizontal for a bit...or a weight could be secured to the anchor line at a certai distance to help keep it pulling horizontal.IP: 156.34.84.231 |

regarding the toppinglift - you should have a plastic sheave inside you mast head casting. That is why the casting is an ugly shape. You could put a sheave at the fwd end and rig a masthead genoa on her too... that would be fun....------------------
