Magus projects and details


When we bought Magus in 2008, she was a bit rough, but basically a sound boat with a sound engine.  Old sails and electronics, and she hadn't been hauled in years, but the bottom was cleaned by a diver a couple of times a year.  Magus was built in 1971, and has had three previous owners.  (See one story here.)  She had been in the Caribbean for the previous 22 years.  The engine is a Perkins 4.236, 85 hp.

In early 2022, the topsides were refinished in a big way, meaning all the old paint was removed, sanded smooth, filled, and painted with 2-part primer, sanded again, and given one or two coats of 2-part finish-- all Interlux products. The finish quality is not as good as I'd like, but it passes the "20 foot rule," it provides an excellent protection layer, and it is an excellent base for the future finishes that will (eventually) be required.  Another part of the teak grating in the cockpit was refinished also.  

In 2021, the teak cockpit sole and door were refinished, and the overhead light fixtures were replaced; all bulbs are LEDs.  We also bought new house batteries-- (3) 100 A-hr wet cells.  They work great with the solar panels and engine alternator.  Separate starting battery, of course, with a Blue Seas combiner to keep them separated, unless either charge source is available to charge both battery groups.  Plenty of other good equipment, as you can see in the details.  

A great starting point to get the overall data on Banjer 37 motorsailers is the club website at: https://banjer37msclub.tripod.com/mission.htm.   Banjer 37 boats seem to have a wide variety of sail plans, based on the information of the website, meaning that the rig on Magus is different than anything  on the plans shown on the website.  The rigging was reported to have been replaced in 2002, and she has nice Sta-lock fittings top and bottom.  As detailed below, the backstay and jib headstay have more recently been replaced. The chainplates are unusual, being eyebolts through reinforced places on the deck.  Between 2008 and 2012, those eyebolts were all replaced.

The sail area was fairly small, at a total of about 450 square feet with the working sails.  This is still pretty good in the tradewinds, but doesn't do much in light air.  All of the working sails were replaced by 2015, starting with the mainsail in 2009, the new roller jib in 2013, the mizzen in 2015.  The new bowsprit and roller jib are fantastic, see related post.  With the roller jib, the total sail area is 552 sq-ft.  The furler is a CDI Flexible Furler 7.0.
Here are some of the sail size numbers:

Mizzen:  P=15.66, E=8.00, Luff=16.0, Area= 73 sf
Main: P=28.25, E=13.5; Area=191 sf
Jib, working: about 186 sf
Jib, on roller and bowsprit:  I=31.0, J=12.59, Luff=32.45;  Area= 288 sf

There is also a storm trysail and hank-on storm jib, hardly used at all.

Here is a little more history of maintenance before it gets into a list of equipment and condition.  

The boat was stored on the hard in Virginia from 2017 to 2019.  New bottom paint and engine work as noted next.  

The engine is a Perkins 4.236, with Paragon transmision.  Maintained in excellent condition.  In 2021, the engine hours were about 4,450.  In 2017, work included:
   The transmission was removed and rebuilt with new bearings and seals.  On re-installing it, the engine mounts were all replaced.  Engine work (at 4,210 hours) included replacing all of the injectors, replacing the exhaust manifold (with SS) and replacing the exhaust elbow.  A sender hose for the oil pressure gauge was replaced. 
  Since 2008, the heat exchanger water pump was replaced, the salt water impeller pump was completely replaced, and the high pressure fuel pump was replaced.  The seawater impeller is inspected at least annually, and has been replaced few times, but it does not seem to wear much at all.

In 2016, at Brewer Marine in Freeport, the topsides were painted, along with the bootstripe, and the bottom.  A completely new backstay was installed (to be safe, it was not showing signs of stress.) The center water tank was cleaned and painted with water tank epoxy.  The big project was the replacement of the two hydraulic cylinders at the rudder end of the steering system.  (The old ones were leaking and were probably original.)  In 2021, the remaining hydraulic steering hoses were replaced, so that system is in great shape.  A hot water heater was installed, for either plug-in at the dock, or through a heat exchanger when running the engine.  

Also in 2016, the rest of the cabin cushions were replaced: forward berth, table/ convertible berth, starboard settee.  A full marine survey was performed so we could get hull insurance at that time.  (Previously, we had liability-only insurance that did not require a marine survey.)

In 2013, the cutlass bearing was replaced.  The masts came down for inspection, and to install the roller furling system and a Solent stay with removable lever and pin.  (So there are two "head" stays.)

All of the through hulls have been inspected and the engine intake one replaced.  All the valves and hoses have been replaced. (There are four: two cockpit drains, the engine intake, and the old head inlet used for a deck wash-down pump.)

The marine direct discharge head was removed, the discharge thru-hull was removed, and the hole was glassed over by professionals in Ponce, Puerto Rico.  The head is now a Nature's Head Composting Toilet that separates urine from the solids.  We love this unit.  Venting for the head is through a Day/night solar vent on the deck.  There is a small (5 gallon) holding tank for water from the sinks and the shower.  It discharges through a macerator pump to a discharge above the waterline.

Anchoring gear:
Simpson manual windless with a chain gypsy and rope drum. 
Rocna 44# with about 160 feet of BB 3/8" chain. This anchor is on the bow.  Chain drops down a tube from the windlass to the forward bilge.
Fortress Guardian, G-23 with 30' of 3/8" chain, 100' of 7/8" nylon rode.  This anchor is also on the bow. The line rode runs through a deck plate.
CQR 45# as a spare/ second, on the forward deck.
Danforth standard, 85#, "hurricane anchor" with 33' of 1/2" chain, another 100' of 7/8" nylon; all stowed in the port cockpit locker.
A small Danforth and 200' x 1/2" rode.

The compass is a Danforth Constellation, rebuilt in about 2013, looks like new.  The steering wheel has a rudder position indicator.  Engine and other instruments, alarms, controls at the steering station, with the primary chartplotter; see other equipment below.

Electrical system

The 120 volt dock power runs through a galvanic isolator system and to plenty of interior outlets. The battery charger is a Pro-Natic 12-30 P by ProMariner, about 2013, will also operate on EU power of 220 volt, 50 cycle.

12 volt system: (3) deep-cycle batteries (100 amp-hrs each, new in 2021) for the house, and a starter battery (2019.)  The engine alternator charges the starter battery first; the solar panels charge the house batteries first, but they both run through a Blue Seas combiner-isolator so all batteries are charged from either source.  Solar panels on the Pilot House roof (about 2015) are three 100 watt units.  The controller is a Xantrex C60, which has plenty of capacity to add a wind generator.

Nav lights are LED's, and so are all of the cabin lights.  New teak light fixtures in 2021.

Other electronics:
  • Standard Horizon CPV 550, chartplotter and VHF DSC radio, exterior GPS antenna, with C-map M-NA-M033.40, Fall 2017, Atlantic Coast, Gulf of Mexico and Caribbean.  (Primary plotter.)
  • Emtrak B100 AIS transceiver connected to above unit.
  • Raymarine a67- 5.7" MFD with US charts and digital radar (could accept the AIS signal) and for a backup chartplotter.
  • West Marine VHF radio (old). 
  • [There are thre (3) VHF antennas-- two on the mizzen mast, one on the pilot house roof; they can be interchanged in an emergency.]
  • Autopilot: Si-Tex SP-110, about 2013; the hydraulic steering pump is older; hoses replaced in 2020.
  • Cruzpro speed/ temp indicator and removable through-hull, 2016.
  • Uniden depth gauge using the old bronze through-hull.  (Inside sender as spare.)
  • Island Time Wifi booster antenna and router, 2016.
  • McMurdo Smartfind-plus 406 GPS epirb, 2016.

Water tanks and fuel tanks are built into the hull.  Two (2) 100 gallon fiberglass tanks for water; one coated in water tank epoxy, the other cleaned but original coating. Pressure water.  Hot water from heat exchanger or dock power.

Two (2) 125 gallon fiberglass tanks for fuel, isolation valves.  Dual Racor fuel filters, and Parker FPM-050 fuel polishing pump.

Propane gas stove, Force 10, 2 burner and oven.  Two 10# tanks (both replaced in the past 10 years) in deck locker.  Selenoid valve.

The built-in ice box at the galley is used for storage.  A 12-volt Isotherm chest refrigerator with added insulation is located above the starboard settee, and is very efficient.
 
Forward hatch has Oceanair retractable screen and shade.  Portholes have screens.  Opening sliding windows in the pilot house have screens.  The door has two hanging screens.

Plenty of lines and fenders.  Swim ladder(s).  Man-overboard sling.  Plenty of spares and tools.  Canvas shades, cockpit cover, etc.
