    Anything is possible, never let someone tell you it can't be done. It is done everyday and the guys that are already there did it in the past. To start any company you want, without huge funding, you start small crushing the overhead and you bust your *** until you get to the next level, then repeat. Small builders do want to keep there staff produceing so that they have a stream of cash flow, they will build for you. This is the USA, anything is possible and there is always someone out there that is up for it. I visited a builder yesterday that will build my boat and let me put my own hull numbers on it and sell it under my name. My tooling cost, zero, my shop cost, zero. Will I make the spread that he make, no, but I also don't need the same margin because I don't have the overhead he has... Nike said it best, JUST DO IT, don't be a girlscout.

    I am a boat builder in Thailand
    Most of my boat is over 65' and builted from steel.
    Cost for 65' steel hull with all super structure is less than 100,000 dollars (FOB).
    Any one interesting?

    I have a 1972 ss235,i recently repowered it with a 2004 merc 5 liter with a alpha one outdrive.Iam having a problem with the boat cavitating on quick take offs under full power.The new stern drive is 3 inches shorter then the old OMC.Would it efffect the performance of the boat to lower the motor and stern drive 3 inches down from the original location or would this change the performance of the boat.Any information on repowering of the ss 235 would be appreciated.

    Eric, I have a 1972 SS235 which was recently repowered with a new merc 5 liter and alpha one new generation stern drive.Iam having problems with the boat cavitating on full power take offs.The new outdrive is 3 inches shorter then the old OMC outdrive.The company has agreed to move the motor and drive 3 inches lower,but they do not know how it will effect the boats performance.Do you think lower the motor and drive 3 inches will effect the boat.Any information would be helpful. retired one

    Retired one,

    If the original engine and outdrive were 3" lower, and the new units are higher, no wonder they are cavitating. Going back to the 3" deeper will be a step in the right direction.

    Cavitation is caused by the propeller sucking air from the water surface. The deeper the propeller, the harder it is to suck air. I do not know the size of the new prop compared to the old one, so if it is bigger in diameter, you may still have a bit of a problem. If the new prop is bigger, putting it down the 3" may mean that its tips in the upper position can still suck air. The outdrive should have a good large cavitation plate over the prop, which acts like a fence to prevent the prop from sucking air. I would check where the new cavitation plate is positioned compared to the cavitation plate in the older unit. If the new prop is bigger, it may have to go deeper than the 3".

    I can't imagine that moving the outdrive down 3" is going to make much difference in performance--there will be some, but probably pretty negligible. If you have to go deeper to get a bigger prop down deeper, then you will begin to affect the drive performance--there will be a bigger moment between the prop drive line and the boat's center of gravity, and that greater distance will have an effect on planing performance. It may cause the boat to trim more aft when accelerating onto plane, so you may find you have to adjust trim tabs differently when accelerating--assuming you have trim tabs. It will take a little trial and error to figure out the final performance.

    To summarize, dropping the engine and outdrive back down 3" should not hurt, but you may want to position the new units to the level of the cavitation plates, not the centerline of the prop shaft. This all depends on the diameters of the old and new propellers. In general, to fight cavitation, a deeper prop is always better than a shallower prop. But if you go too deep for the hull design, you may affect planing performance, particularly on acceleration from stand still to full plane.

    I hope that helps--although not necessarily the right question for this thread.

    So often it is assumed that there is "rhyme and reason" to the price of boats. Big sticker prices always evoke mental images of big profits in the minds of the uninitiated. Putting a boat on the market is a dangerously expensive proposition, with many pitfalls. Marketing follows no rules familiar to the typical agent. Projected labor costs can run away in totaly unexpected ways, even to the experienced. I have seen completely sensible well thought out designs that were buillt by good builders for a very real market and put out there by good salesman at good boat shows, totaly flop...not sell one!
    How does it happen? I don't know. But think long and hard before you try to compete with the world of really brilliant and dedicated individuals out there that desperately want to make a living in this business because they really love it. They will all tell you they have to love it because that for the same investment in education and skill they could make a hell of a lot more money working in the house building trade or some such.I will tell you the same thing I tell my is a poor career choice if your inspiration is money.

    I agree with Eric. Why would a boatbuilder build you a boat and allow you to take the profit from an already skinny margin? Are you a brokerage with an understanding of an existing untapped market that could guarantee him enough repetative work to streamline the contruction process and find enough margin for him to profit?
    It sounds like I am discouraging you but I am not...I love it when somebody comes up with a great idea out of the blue and makes good. It gives us all hope.
    I guess I am just saying be brutally reallistic and do your homework and... don't borrow the money from freinds or family.

  8. Mr.

    I am in Australia and have wondered about having a yacht built in Thailand, somethind along the lines of a Roberts Spray 60, though I would prefer alloy to steel. can you help me and what would the cost be. my email is
    Thank you Roger
  9. Mr.

    Hello again I have just noticed you work in composites could you do a roberts spray 60 yacht in composite The spray 60 is just an example of the type of yacht that appeals I like the traditional style of yacht like the formosa etc.
  10. Yes see my post on roberts spray 60 in alloy or composite

    Did It!!

    Hi Everyone, If you really want to do it you can. It has been over a year since my last post. I am just finishing my first boat. I did spend some $$ but it was well worth it. I am ready to sell my first boat. Finally something different, check it out. More finished photos will be going up soon. Thanks and good luck to all those who want to build boats. Just do it! Kurt :)

    It will be hard to find a boat builder to do that. The profit margin isnt there with two companies trying to make a living out of the same boat. I tried it. The second Co. wanted more and more done for the same amount of Money.
    But Good luck
