Of course, they cost huuuuge bucks. The only place I know of to get them is ScanMarine in Seattle. See Boat heating and cooling experts, Wallas heaters, Ardic heaters and other diesel boat...

Catamarans' motion
A beamy, light boat will have a quicker motion than a narrow, heavy one. A good catamaran is a very beamy, light boat, indeed. Ted Brewer made an equation to quantify this, and called it the...

You can get strong shackles now, so big links are apparently no longer necessary.

181 NM = @ 133 foot pounds = @ 65 hp. diesel
Hi, Fastcat
That (181 NM) looks about equivalent to a 65 hp diesel, in terms of torque at the speed they are usually run, ie. about 2/3 of the max rated rpm. ( HP = Torque * RPM / 5,252 ) For...

Holding power
The problem with "holding power" is that it varies with the bottom. IMHO, the Rocna/Manson Supreme type is best in the typical sand or firm mud bottom, but the Fortress is best in soft bottoms, and...

But how much does the lass mass?
No specifics there, I fear, and it doesn't seem meant, as you say, for ordinary yachtsmen-ie. those using anchors under 75 kilos. I always use anchors that weigh less than my wife. And, oh dear,...

-Reply to Seer
Hi, Seer-not 15' long, long enough to reach 15' forward of the boat, probably about 55' of line, as you suggest. The beam is 35' 6", but 7' less at the the sampson posts. The Liberty 2500 is...

RE: Why aren't more anchors rated by Lloyd's?
Well, one reason is that many anchors are from countries that aren't all that close to Great Britain, culturally. The U.S. isn't a part of the Commonwealth, for example. Lloyd's approval means...

Anchors aren't made of just any old steel-
Seer-A good anchor, like the Delta, is made with high manganese steel, which is quite difficult to weld without getting cracks in the welds. High manganese steel (12 to 14% manganese) is very...
