    Purchased the study plans for Tiki 46. Now my wants and needs have changed.... Would the hull work?

    Welcome - there are many people here who will undoubtedly be able to help you, I'm not really one of them, but I know they will need considerably more information about your requirements and intentions.

    I'm very puzzled.
    The Wharram Tiki 46 has two hulls - that is a catamaran not a trimaran.

    Wharram is a professional designer with lots of boats built from his plans.
    What do you mean - "would the hull work?"

    It will certainly work for what he designed it for.
    Not as a trimaran, not particularly as a motorboat - what do you mean.

    What are your wants and needs?

    Thank you and for the replying...

    The intent was for my wife and I to sail on, bit we have split...

    I would now like something faster and with needing less room. The thought is I could one just stop at one hull, using it for a trimaran.

    Nope, sell the plans, plenty of dreamers to buy Wharram plans. Buy a used boat and sail away, be careful with tris though, nice to sail but few have practical payloads.
    Don’t build a boat until you have racked up some sea time on different hulls and know absolutely what you want and only then if it can’t be bought.

    Well it would sail but wharrams aren't great cats, it would be a worse tri. And you'd have to engineer the beams floats rig etc. It's not trivial.

    Maybe consider the 32' tri Ray Kendrick offers. Plans are $150AU I think and you could sell on your wharram plans for about half what you paid for them.

    The cost of the plans is trivial compared with the time and money to build. You really are better off putting all that into something good.

    Richard Woods has a range of cat plans at very reasonable prices, something for everyone. There is also Kurt Hughes and a few others I've forgotten just now. Ed Horstman.. If it's just you a 30'ish cat or 33' ish tri will be adequate. A Tiki 46 is a ridiculously big boat, IMO too big for 2.

    The plans mishap is only about study plans of £ 19.00 - (US $), I suggest to let them to your ex wife, and take something else instead, or you can put them for sale here free, or somewhere else . . . :)

    + 1 ‘‘ The Tiki 46 is a boat designed for Blue Water sailing, with live aboard space for a crew of up to 10. ’’

    Build and cruise and maintain costs and work time are accordingly to that 10 persons figure.

    - One hull is a Monohull.

    - Two hulls is a Catamaran, or in another configuration a Proa.

    - Three hulls is a Trimaran.

    One originally catamaran hull will float, but only on one of its sides, and maybe also upside down, but not right side up . . :(

    For building a trimaran with an originally catamaran hull at center...

    Yes, that's understood. I would build outriggers and one major point aluminum, I am a welder. I see no reason to not use what I have mastered.

    I would take into consideration other designs but I do like wharrams look. I'm sure I could adapt that.

    Making it look similar is easy.
    Keeping it in one piece on the water is entirely a different thing.

    No-one can provide any useful suggestions with as little as you are willing to talk.

    Good luck.

    FYI, welded aluminum tends to crack in fatigue situations. Sailing is a fatigue situation.

    Below a Wharram that broke in two pieces in 2009 in Cook Strait NZ on her maiden voyage because the builder didn't built the beams as per plans, then another guy salvaged the boat, built new beams as per plans, and sailed on forever . . .
