    Hi am new to this forum. Have not built a boat before but have been around and owned a couple over the years. Have decided to go ahead with a build. Having made this decision i would like to go with something a little different from the norm or what i have owned before.
    I Recently saw a aluminium rib or cat style recreational boat while on holidays. A Blackdog Cat 4.0XL just something about the design that I like that is all i can say. This got me looking into deck boats and other twin hull designs. I would be using the boat as dive platform, fishing boat, and runabout on the bay. 4-5 in length?
    I realise the Blackdog is aluminium boat and not quite ready to commit to a welded hull just yet.
    Ply and Fiberglass for me.... so is there any designs ideas that might be recommended?

    Thanks D.

    There is a world of difference between a 4 meter cat and a 6 metre one. One is little more than a toy, and the other is potentially a very capable vessel. How much money are you prepared to expend on this exercise (boat, motor, trailer) ? That will determine what you can realistically aspire to.

    Size matters $$$

    Gave a size range of 4-6 meters to give me a choice of options. The original concept i came up with was a 5.0 meter long vessel. So will stick with that.

    Thanks again D :)

    Why does it have to be a cat ? Unless you are traversing long distances through lumpy water, they may not be the best choice, especially as they usually need twin engines, with the attendant extra costs.

    Prefer the stability of the Catamaran, the usable beam also. Doesn't have to be a cat ....just thought if i was going to build it would be something that i like the look of also.

    how much is you budget? Give us at least a range of what you are prepared to spend - on the whole boat: hull, engines and fittings and all.

    This is important. Buying a used boat is likely way cheaper than a mold - even if it was for free.
