1974 31' Hallberg-Rassy Monsun 31 Nora Marie recently completed a total refit and was surveyed in Near Bristol condition. She was refit to the highest standards for the purpose of long distance cruising. All systems were selected for rugged simplicity and self-servicing. The Hallberg-Rassy Monsun 31 is renowned as a sea kindly, stout cruising boat with multiple circumnavigations.

Rigging and Sails

March 20, 2017 at 3:38 pm
During the refit, the mast was stripped and rebuilt, a new Selden boom was added, and all rigging was replaced. A break-away solent stay has been added for a hank-on drifter and storm sail. A track has been added to the mast to allow for a storm trysail to be bent on and stowed at the deck ready for deployment. Dedicated halyards are present for all of these sails. A new Schaeffer roller furling system was added for the genoa. New sails (main, genoa, and drifter) built by Port Townsend Sails, the loft of renowned cruising sailmaker Carol Hasse, were added last year. Spliced dyneema lifelines were added with pelican hooks at the stern pulpit.

Plumbing and Waste System

February 23, 2016 at 7:16 pm

2016-02-21 16 3

Last week, we finished up installation of the plumbing and waste systems aboard Nora. Obviously, fresh water and waste management is crucial to being able to live aboard and travel off the grid. It is both a great challenge and very rewarding to provide these basic needs for yourself and be able to tailor the systems to be as robust and independent as possible. Nora was designed to spend time in austere, wilderness settings and to be able to provide clean drinking water and handling of waste while off the grid and keep them maintained and operational for extended periods.

There is truly no perfect boat as each design includes trade-offs when compared to other designs. The same is true of the systems designed into a boat. In designing the systems aboard Nora, I veered strongly towards robust simplicity. This provides cost-effective, self-sufficiency, but it often comes at the expense of convenience.

Certainly, the most simple approach for waste would be the tried and true cedar “bucket and chuck-it”. This solution ranges from inconsiderate to illegal in a tight anchorage or marina. A port-a-potty is also a simple solution but does not allow for efficient prolonged storage of waste when required. Just a few unpleasant experiences maintaining a traditional holding tank set-up (or fixing one that clogged and put under enough pressure to back spray waste out the deck valve and all over the deck) have left me wanting to avoid these forever. Many of the chemicals used in these systems are also unfriendly. A nice, middle of the road approach are some of the well-designed composting heads available today.

I have used the airhead composting toilet on a previous boat with great results and decided to install one aboard Nora. With typical use by two adults, the liquids are dumped every several days, and the solids compost down and require dumping every few months. Low-volume air flow is provided by a small CPU fan venting to a UFO vent on deck. The system is simple, low maintenance, and odor free.

Potable water is split into two systems, one for drinking and a fresh water system for the galley. The drinking water is contained in a 40 gallon tank below the V-berth and flows to a hand pump mounted above a gimbaled Berkey water filter. This allows closer monitoring of drinking water usage as well as production of the highest quality drinking water.

The galley fresh water system is split into two tanks with a total capacity around 35 gallons. We also have the ability to divert rain water collected in the deck drain system through a filter and into the tank. The second hand pump in the galley provides raw water for rinsing. The fynspray hand pumps are beautiful, simple, and do not require power usage.

Bottom Job and Stem Piece

December 23, 2015 at 5:08 pm
    2015-12-23 15.30.53 All of the old bottom paint has been sanded off. The hull is in great shape with only very small (<1-2mm) blisters near the water line. These were opened from the sanding and have thoroughly dried out. 2015-12-23 15.32.05 The rudder was loose due to wear on the forty year old bronze pins. All of the bronze straps were exposed, and the bottom bronze shoe was removed in order to allow the rudder to drop and the pins to be replaced. 2015-12-23 15.32.19 2015-12-23 15.35.19 Another major addition as far as functionality is this new stem piece. I designed the piece initially on paper, then built a mock-up out of foam board which was used as a template for water jet cutting of the 3/8" SS plates. These were welded together along with two lewmar rollers and a new, thicker chain plate. The design will allow for the addition of a solent stay, spinnaker tack point further forward, and a block for the anchor snubber line. A longer toggle for the furler is needed for the drum to clear the anchor shank.

Bedding Deck Hardware and a Repower

December 5, 2015 at 4:41 pm
2015-12-05 15.43.56 The next big step has been to get Nora watertight. This involved bedding the ports, hatches, and some of the deck hardware. For anything that is substantially attached via through bolts, I prefer to use butyl tape. Butyl tape is currently regarded as rather old school but is seeing some return in popularity. It works great but is not an adhesive. We have also used sikaflex 295 UV in a few applications where I was concerned about adhesive strength due to not being able to through bolt. 2015-12-05 15.44.45 Another major to-do off the list for this refit was a repower. Nora came with an old Volvo 2002 that had clearly been run hard and put away wet for many years. I firmly believe that sails and seamanship are how you stay safe but having a reliable engine adds another layer of safety and will also allow inland exploration when sailing is not feasible. With help from Pier 77, we narrowed the search for an engine that would fit to Yanmar and Beta Marine. I ended up choosing a Beta 20 due to availability, simplicity, and some really well thought out features for practicality of maintenance in a tight engine compartment on a boat. 2015-12-05 15.46.30 Inside the cabin, the painted overhead panels have been re-installed along with the fixed and opening ports and hatches. 2015-12-05 15.45.39 Nora is quite small with a very tight galley. We needed this area to be as efficient as possible. The original composite counter with wood fiddles would leak water and was causing some wood rot. I took the old counter to a local corian counter fabrication shop. They were able to duplicate the counter in a corian color of our choice with integrated fiddles and sink basin. This now makes the entire counter a seamless, watertight basin and greatly improves the functionality of the galley. We are using raw and fresh water hand pumps for simplicity.
