Haul out

As I stepped out of the house early the other morning, I noted how quite the fall woodlands is vs the summer season. Gone are the summer song birds who's chatter fills the woods from the moment the night scape fades. The sound of the dormant season is of the nuthatch and chickadee with their husky calls. For some reason I think of and older lady bartender, withe her bar room baritone voice when I hear these birds.... the laugh of too many Marlboro's and cheap scotch whiskey.  Why that bird call reminds me of this I can't say, but what I can say is that this subtle change in the surrounding woodlot keeps me well aware that the cold months are soon upon us and it's time to haul Gragodeo out for the first time.

I would have much preferred to keep her in the water over the winter. Having coffee in the wheel house on a winter morning, while looking out on a harbor scape sure did sound appealing, but my wanting to see how the below the water line hull fared during her first season was more important. I'm happy to say that the hull looked good, with no sings of electrolysis or failure of the barrier paint.  The only below the water line issue I saw was where I did not get a good enough scuff on the barrier coat to give enough tooth for the anti foul to be able to bond. On advice from the boat yard paint guru, I'm going to spot sand the areas where the anti foul was blown off by the power washer and re coat those areas only.


The prop is the other below the water  line area that's going to get a hard look. As I posted some time ago, I'm getting a high pitched sound at certain RPM's . Between 1100 and 1650 the sound is most pronounced. There's really no reason for the stern tube bearing to be making this noise as the bearing was  machined correctly, and the alignment is spot on. Now that she's on the  hard, I looked closely at the bearing, and found no signs of wear or any play in the shaft/bearing. The prop was purchased from an on line dealer and is a Taiwanese or Chinese import. After searching out this harmonic issue I'm having, I'm starting to think I have a case of whats commonly called prop sing. Prop sing is where the edge of the prop is somewhat defective and causes a harmonic sound similar to one rubbing a finger around a fine wine glass ( only louder). The fix for this is to machine a 45 degree chamfer on either the trailing edge or the leading edge. This can be done in field or by a prop shop, and I think I'm going to have a prop shop look at this for me. I want a professional to measure the prop and tell me what I  have in regard to quality beginning with the bore, and ending withe the blade tips. I went the cheap route when this prop was purchased so now is the time to see how expensive my cheapness actually is.

The cruise down to the haul out yard was done with my 17 year old daughter on a drop dead gorgeous fall day. I recorded a short video of our "three hour tour" so that when the winter blues has found me, I'll have this nice video reminder of a great day to cheer me up.


There are some big projects that need to be done on the boat build this winter to get her to a more finished state, but they will have to be worked in with some renovations we'll be doing on the house. My goals for the boat build this winter are to install the mast and boom so we can carry a dinghy on the roof. Complete the hydraulic system so I don't have to  hoist the anchor by hand next year and also have the bow thruster operational. The air conditioners are on board, but have not been hooked up, so that's a biggie on the lists. While I'm up on the lid working on the mast, I also want to fabricate the  hand rails for the salon lid.

The next weekend will be spent winterizing her, and after that a few projects around the house need to get finished. We have plans to take a few extended cruises next season, and getting my list checked off is going to be tight given that my launch date is only seven months away. Sound familiar?

  2. Hey Rick,

    My video vanished, but I saw your comment. We were making around 8.5 knots @ 1700, and did see some 9.5 knot speeds. There's a bit of current pushing us, so I'd say 8 knots.

  3. Looks beautiful Conall - has to feel great too. Nice wake for 8kt. PS - -with outrigger type stabilizers, your boat would run the coast no sweat. There were about 8 powerboats on the BaHaHa, and only one matched yours.

  4. Thanks Norm. The wake is pretty gentle. When we're wide open, pushing 10 knots, we throw a pretty decent roller straight off the stern.

    In what way did one of the power boats on the HaHa match mine?

    I've read your update many times. I'm big time happy for you two.

  5. Nice blog! I just discovered it. I had a large prop rebuilt last winter by Kahlenberg marine In Two Rivers Wi. They did a lot of work repairing it. The pitch was off as well as blades varying in size. They did the work for half the price that a new one would cost. Feel free to contact me if needed.

  6. Thanks Dave,

    I'm thinking I'm going to pull the prop after the first of the year and send it off to get looked at. My guy at the boat yard has an outfit in FL he likes, and is putting together enough business to get a decent shipping price.
