Windlass on deck or in the anchor locker???? Easy choice! Okay so this should spark some discussion!
On Delicia, We recently removed the original below deck Simpson Lawrence Windlass and replaced it with a HRC10-8 Maxwell, $1700. It is an excellent windlass. Less than half the price of a Light House. We had a Maxwell RC Series RC10-10 Vertical Windlass on our 350. Maxwell makes good products. It was also an excellent windlass but it was a below deck, vertical windlass. If we had maintained it as directed, i.e. removed and greased every 6 months it would have worked much longer. But I didn't, and motor became "one piece" mated forever with the gear box, as things tend to do in the saltwater. Here is the basic problem, which makes deck mounted windlasses superior - - PERIOD. All, electric windlasses use big DC starter motors, usually 12v, These motors all have a mild rolled steel cases and iron magnets with copper windings plus other copper parts. Even on the vaulted Light House. These are motors, by economic necessity, come from the high production volume auto/trucking industry because they are affordable components. Also DC motors need to have iron and copper parts. So.... when they get wet they rust and corrode. Look at the pictures on the Defender Web site. While the working heads of these pretty windlasses are fancy chrome plated bronze, the below deck parts truck starter motors - usually Italian - and they go fast when they get salt water wet. While below deck seems like a great idea, in reality it is terrible, because the chain drips on them and they live un protected in the warm wet chain locker. The salt water from the chain along with the mud and other stuff drip all over the motor and connections, it never dries out in there. If you don't remove, clean and grease the motors and connections frequently they fail and they corrode and become "one" with their aluminum case gear boxes. If they are mounted on deck in a nice fiberglass box they stay much dryer and easier to service. Removing the failed windlasses on my 350 an IP40 was hard. You can't use a big hammer because you will destroy the deck. On the IP40 I used a 5/8" drill bit to cut around the shaft and the a cold chisel to cut the rest of it when I removed the Simpson Lawrence. On the 350 I used a Saws-All to remove the below deck Maxwell. The Light House attempts to solve this problem with by using a robust looking case to protect the motor which hangs in the slop below deck. The rest of it is nothing special - a worm gear drive like most of the others. You have to cut a fairly large hole in the deck to accommodate the motor and case.
And while I am on this rant - Manual windlasses work well and are really "salty" looking. - BUT, they are slow, require lots of effort, and it you have to anchor several times to get it "right" like many of us do, you are tempted to say "hell with it" that is good enough "I don't feel like pulling the anchor one more time". Also in a 40k squall at 3 AM it is nice to be able to have your female significant other get the anchor up quickly while you motor off through the dark anchorage around the other boats that are dragging down on you. If you have a remote switch at the helm, (not a big expense) you can do the 3 AM drill alone and she can sleep, or if you are single handing you can do it alone because you have no other option. The single hand anchor drill is very hard to do safely do with manual windlass in a crowded anchorage, especially in a night time blow. Because, when the anchor comes out and the bow starts to blow off you can't run to the helm and motor away with 20' of chain and anchor still in the water. You tend to be stuck where you are . . . so you need to anchor in the "right spot" for all conditions, a problem that the manual windlass makes tougher.
