Re: center of gravity

While designing and building our trailer, we made it so the 3-axle set was movable as a unit on the main trailer frame. I used my "best judgment" for the initial loading of the boat on the trailer and ended up with about the right amount of tongue weight. I designed it so even the bow support was fully adjustable but my welder had other ideas so I had to do that part over myself.

The fellow that pulled my boat and trailer over 5000 miles said it worked well except that the tongue flexes a bit due to it's length and he wished it was a gooseneck design. I did not got with that option since, back then, I was thinking of getting a small boom truck for my business and it would not accommodate a gooseneck trailer. I fantasized about being able to not only tow the boat and trailer anywhere in North America, but even step the mast myself. Never happened though.

I will try to send some pictures soon. I am sick today. I think I have been burning the old candle on both ends!

  Mr. Perry reported to me that sixteen feet aft of the stem of the vessel lies the center of gravity (on land) for the purpose of building a trailer.

   

  Van…

   

  My 2 cents worth.

    I measured my Baba 30 today and the height from the bottom of the keel to the top of the mainsheet traveler is about 10 feet 8 inches. The width of the keel is greatest on the forward portion and is about 12 inches wide. I have the keel sitting on about 3 blocks of wood about 3 inches thick so I can still fit the traveler's straps under the keel.

     

    With my boat on the trailer it is about 12 feet high! I have a mast carrier on the port side of the trailer so I don't have to have the mast on the top. I verified B Perry's info that the keel bottom "starts" about 16 feet aft of the bow (stem). It is quite a load but my trailer has about 6,000 miles on it now.....I think that is even more than we have sailed it!

     

    I managed to get some pictures to Alan but I don't think I can post them to the list.

     

    I hope that helps,
