Maxwell 2200 Windlass Installation
windlass looking forward.jpg (279715 bytes)
Forward view. Note height of base. 4ea thru bolts, 6ea lag screws, all bronze. 3/4" ply & fabmat laminate w/ 1/4" glass cover

Note vertical axis ratation & port offset
windlass offset2.jpg (290294 bytes)
Offset & rotation very noticable. Note chain pipe, cat hawse pipe, and fwd aux hawse pipe. 1 chain & 2 rope rodes at hand
fair lead.jpg (375756 bytes)
Both anchors are captured. Chain fairleads thru horn & yellow anti-chafe material. From Panama Canal Locks fendering system.he 2200 cat to chain width is wider than the stock stemhead fitting. The "horns" are a refit on the original stemhead fitting. 
horn detail.jpg (306368 bytes)
TFor raising anchor the chain is lifted free of the horn and fairlead directly from bow roller to gypsy without touching the SS fitting or the teak. Chain leads straight from gypsy to horn and turns to bow roller for lowering chain. Up the chain is tight and does not slap; down it rides on the plastic material. This plastic is very tough and does not cut.

My high current buss bars and distro system for anchor windlass, inverter, hf radio, and main breaker panels. The blue pipe directly penetrates the battery compartment. Vapor sealed. 2/0 from each battery to 300 amp cont rating battery switch then to common buss bar. Each battery fused at 500 amps for safety incase of massive short to prevent battery explosion

Notes

The windlass must be offset and rotated to use the original stemhead fitting. You then need to add a "turning device" on the aft end of the fitting to fair lead the chain or rope from the bow rollers to the gypsy or cathead.

The mount through bolts on the raised base will not insert from above, so the insert from below w/ nuts and crown nuts for finish. 

The 2200 has enough power to flex the deck so maybe an under deck beam should be laminated in a fore & aft direction with a cross brace thwart ships in the vacinity of the staysail stay fitting. I note that some of the CSY owners has added a jumper stay from the base of the stay sail stay to the hull or lower bulkhead to stiffen the foredeck. With the combination of stay sail loading and the windlass loading, there may be failure of the laminate without some sort of reinforcement. 

I have done neither, but will keep a close watch on the installation.

I decided to use only 5/16' HT chain, going for the extra length and lighter weight. The chain is my working anchor and not intended to be a storm or heavy weather anchor. For that I will always return to lots of scope and my 3/4" or 1" nylon double braid.

Yanmar JH3-TBE Installation

In December, 2000 a new Yammar JH3-TBE 75hp turbo engine w/ a 3.3:1 mechanical transmission was installed in POGO II. The project required cutting the engine beds, installing new 3" exhaust hose, and some other small mods.

The installation was smooth, and the new engine is easily removable through the existing engine room access hatch without any disassembly of the engine. The reefer is top mounted using a SeaFrost (http://www.seafrost.com/acc.htm) compressor mount and a Sankyo 508 compressor. The alternator is a Balmar 100 amp dual foot, single belt. 

The engine was modified to heat water for ships potable water using the engine cooling water.

Sea trials confirmed the selection of the motor/transmission combination; max fuel efficiency is developed at 2500 rpm and the vessel makes 6.8 knots at that speed. The top speed at 3800 rpm is over 9 knots, but this exceeds the hull speed of the vessel, even with the stern "scoop" extension, so the stern "falls" into the stern wave hole. However the engine loading vs rpm vs speed is perfect for the CSY using the original propeller / shaft assembly.

Log Cut.JPG (401537 bytes)

One of the biggest parts of the project was changing the angle of the engine beds. An offset table was developed lower the forward end of the logs 7 degrees. The mount was then cut using guide battens and a sabre saw.

The mounts were then extended inward and raised a couple of inches to align the engine with the existing shaft. We then needed to break out some of the cement in the keel area under the bell housing of the engine to give a 1.5" clearance for engine movement. Since this formed a "lake" under the bell housing, so a "ditch" was made to drain the clearance area forward to the bilge. Total depth about 2.5", then the area was glassed back in to the original thickness over the concrete filler.

The original navigation table was removed. A bookshelf, reading chair, and storage lockers installed. Bit messy as area is "underconstruction".

The aft head was never installed, and the area made into a navigation station / radio room. Sit down computer station, stand-up chart table, and lots of storage.
