Mango Mama sold

Just a quick note to let anyone interested that we sold Mango Mama In February 2014 after a stint in the NE Taylor Boatyard. The bottom gelcoat was stripped, some minor repairs completed and barrier coat and bottom paint applied. Also, the rudder was pulled so the rudder shaft mount could be rebedded. With some other minor work, the total came to around $8,000. We're sad to see her go but it's past time to move on. I'm glad she will get the use and treatment she deserves. Bon voyage.

My Last Trip on Mango Mama

So many of my voyages have started with cold weather. It was mid-March in central Florida and the early morning 40° weather was not appreciated. The pilothouse offered some shelter but I had to keep the windows open because the condensation obscured my vision. A small heater would have helped a lot.
A mist rising from the warm spring fed Crystal River grew thick enough at one point that I stopped and drifted while I got the laptop navigation program going. With clear direction from Coastal Explorer, Mango Mama ventured slowly until we rounded the bend and the morning cleared abruptly. She retraced our course in reverse from a year ago but this time I would hand MM over to Whiteaker Yacht Sales in Palmetto.
This was my first time solo with Mango Mama. The only difficulty was preparing food and bathroom breaks. Out on the open Gulf I let her run ahead on autopilot while I took a few minutes as needed.
I planned to anchor behind Anclote Key. Early on, for some unknown reason, the navigation program estimated arrival around 9-10 that night. I pushed the engine up 3500 rpm to get the speed up to around 9 knots. I finally figured out a better estimate and dropped MM back to her sweet spot, 2600 rpm cruising around 7 knots with minimal smoke. Above 3000 rpm, these Volvos run inefficiently, wasting fuel and creating soot.
The rest of the day warmed up and was uneventful. A couple of dolphins came by but they seemed intent on food and had no time to play. When I neglected to dodge one crab pot float, the propeller crumbled it, but the Shaft Shark line cutter has not been challenged as far I know. Mama rolled a little on the part of the course parallel to the swell but she maintained her dignity and never got uncomfortable. My typical tall travel mug was fine today but tipped over a couple of times when we were waked on the next day.
Having made good time, we proceeded past Anclote Key and anchored in six feet of water just east of Honeymoon Island. Using the windlass clutch to lower the 88 pound Delta can be a little tense and noisy with the chain rattling over the gypsy but it’s easy to control (installing the two-way controller is one task I didn’t get to do). We settled down for a quiet night and watched the sunset over the island but it didn’t seem much like Honeymoon Island without my wife.
I woke at four for a quick trip to the head. It was cold so I cranked up the generator and turned on the heat pump before getting back under the covers. It was very comfortable when I had breakfast and fixed coffee later. I went over the charts for the ICW for the day’s run through Clearwater and St. Petersburg then across Tampa Bay and up the Manatee River.
The Lighthouse windlass made short work of retrieving the anchor. I let it drag at the water surface for a minute to wash most of the hard-pack mud away, and then seated it in the bow roller. We were underway. I lowered the mast and antennae before the first draw bridge to reduce our needed clearance to 16 feet. After the many delays experienced in my sailing days, it seemed strange to simply steam through the bridges without waiting for an opening.
Maneuvering the channels and avoiding other traffic took constant attention. The autopilot still did most of the work with occasional tweaks and switching to manual control when needed. There were the usual few inconsiderate skippers throwing huge wakes. I tried to angle across them when I could but there were some that rocked Mama pretty good. I spilled my coffee a couple times in the pilothouse but everything was fine down below.
The light chop crossing Tampa Bay was no trouble and only one course change was needed to avoid an outbound tanker. I had to watch the inbound current as it swept us up the Manatee River to stay out of the shallow spots. Ed Whiteaker met me at Regatta Pointe and there was a broker friend there who showed keen interest in Mango Mama. I’m getting pretty good at handling the single screw while backing into her new slip. The strong bow thruster really helps.
We had adjusted the lines and I was showing Ed around Mango Mama. This was the first time he’d seen her in person. He was impressed.
Then the light of my life arrived. I wasn’t aware of how much I had missed her. We’re off on another of our adventures. And Mango Mama is ready to help someone else find their adventure.

Mango Mama is for sale

We purchased Mango Mama for $109,000 in January 2011 with plans to live aboard and cruise Florida and the Bahamas. She was basically sound with low hours on the engine and generator. She needed updating and we knew she would take some work but the old world teak interior was still beautiful. After a lot of hard work and investment, we've enjoyed using her for a few local cruises and as a liveaboard, but no extended cruising. Health and finances dictate a different plan.

The list of features and upgrades is extensive. We've made Mango Mama an absolute joy to live aboard. Her full width cabin provides accommodations rivaled only by much larger and more costly boats. Her 9'3" x 10'6" salon with more than 6'4" headroom provides plenty of room for a built-in L-shaped sofa, two recliners, and an entertainment cabinet with room in the center for a large fold-out dining table. We use a smaller lift-top coffee table (original table in storage). Double doors open onto the spacious aft deck cockpit.

Forward a passageway and pass-thru window open onto the large, completely refurbished galley. New Silestone quartz countertops surround a large stainless sink with gooseneck brushed nickel pull-out faucet and a new Force 10 propane stove and oven. The quiet new Dometic Marine air conditioner with UV air purifier is tucked under the back corner of the counter for easy access. A sculptured bronze light fixture and a large capacity efficient Vitrifrigo AC/DC refrigerator/freexer finish off this wonderful galley.
The head just off the passageway also has been refurbished. New brushed nickel shower head and non-scalding valve were installed in the roomy shower. (The non-scalding valve became a top priority the first time Victoria turned on the cold water while I was in the shower.) The countertop is the same durable quartz and brushed nickel faucet but with a very nice china bowl. The heart of the head ;-) is the top-rated Raritan Elegance electric toilet. With a macerator in the head itself, all waste lines are 1" in size, minimizing the volume of flush water required. The flush is directed by a three-way valve to the holding tank or through the Raritan Purasan treatment system for direct discharge in most areas. The original stainless steel holding tank had developed pin-hole leaks so it was replaced with the heaviest top-rated plastic tank available. All waste lines were replaced and the new holding tank has never been used.

The center queen stateroom with lots of ventilation and beautiful teak woodwork is a delight. Numerous drawers, two large closets, and a vanity cabinet provide lots of storage with no musty odors. The four bronze portlights are fitted with frosted liners to ensure privacy at the dock. Manita (the manatee decoration) watches over us providing calm assurance at dock or at anchor.

Mechanically, Mango Mama is in great shape with less than 2200 hours on both the Volvo TMD31A 100 hp engine and the Westerbeke 8kw generator. Both were thoroughly checked out at the survey and the belts and hoses replaced to be on the safe side. Dual Racor filter elements and a separate fuel filtration system keeps the fuel clean in the 260 gallon tank. New AGM batteries provide plentiful no-maintenance DC power away from the dock including for the powerful bow thruster and windlass. The Lighthouse windlass easily handles the oversize Delta 88 main anchor.

Mango Mama's spacious aft cockpit is a great spot to enjoy sunsets in faraway places. And she is ready to go cruising at a moment's notice. The Krogen Manatee is well suited to coastal cruising and island hopping. She may be the ultimate boat for the rivers and canals of the Great Loop. We hope to receive reports from the new owners so we can enjoy cruising Mango Mama vicariously. She's currently in Crystal River, Florida, and we love to show her. One couple has been looking for a while and said she's the nicest Manatee they've seen.

    Mango Mama has two deficiencies that may be of concern to some. I am convinced that these problems need little if any repair. However, for those who want to make her perfect, they could take some investment.

    UPDATE 2/19/14 - The hull blisters described below have been repaired. Several prospects were scared off because surveyors pronounced dire warnings. It turned out as I expected that the problem was superficial although one area did require more in-depth repair. Another surveyor who inspected the repair said he would do the same thing if he owned the boat and bottom job will probably out-live the next owner.

    Mango Mama has superficial hull blisters which are cosmetic and not a structural concern. The bottom was previously peeled and barrier coated. For some inexplicable reason, it appears that a thin fiberglass layer was applied over the barrier coat. It's this thin fiberglass layer that is blistering. Below is a quote from the marine survey in December 2010. During this inspection, a number of blisters were lanced and the barrier coat below them was found intact.

    During the time of wetted surface inspection vessel was sighted with surface blisters with approximately 30 blister sights per square foot noted in way of the wetted surface of the hull. Blisters were embryonic to ½” in diameter with some random larger blisters noted. No pattern or grouping of osmotic blisters were noted during inspection of the wetted surface. Blisters were evenly spread over the wetted surface. 
    It appeared that the bottom wetted surface of the hull was previously peeled from the light water line down to the keel to address a previous blister problem. The blisters as sighted during this drydocking were surface type and seemed to be localized to the surface barrier coating applied during the previous blister repair. These surface blisters were not of the osmotic variety and were not into the laminates of the bottom wetted surface or the hull sides.
    Complete repair would involve scraping or high pressure water spray to remove the thin fiberglass overlay. After a close inspection to ensure no further concerns, another barrier coat would be applied to ensure the bottom is properly sealed with bottom paint applied directly over the barrier coat. However, I don't believe this work is necessary. Normal hull maintenance is all that's required.

    Mango Mama also has a problem with the pilothouse roof. From inside the pilothouse or from the deck outside, there is no visible indication. However, by climbing up a couple of the mast steps, you can see that the top of the roof has collapsed and rain will puddle in the center. This is a common problem with the construction of Krogen Manatees. One owner completely removed the upper skin and filler and rebuilt the roof which was a tremendous amount of work. Most owners take my approach; make sure the penetrations are well sealed and don't worry about it.

    These are the kind of problems that may be encountered on an older yacht. However, with the gorgeous and roomy accommodations, excellent mechanical condition, and the upgraded systems, they will not be a deal-breaker for the right owners.
