    Try looking at NACRA's and Tornados as well, H16's are not the best even in there original config. Also the center board cats offer the option of using the boards in the Alma's (there are pro's and cons), maybe you can avoid having a cb case in the main hull. If you do get a 20' cat like the Tornado you may find that the Alma's can be placed far enough back to use the rudders as you initially intended.

    These are some shots of a Typhoon, it's a Tornado conversion that might yield some ideas.

    Delane,
    It has been 6 months since we saw pics of the tri in the water. What is your current status this Christmas?

    thanks for all your responces

    Hey- just a quick thank you for the responces to this thread. My plans to turn my 26foot surf boat into a multi hull continue to gian traction.
    I am torn between simply modifying and bolting the 18' hobie across the top of the surf boat hull and using the hobie rig and rudders- it seems like the simplest yet less astetic of two options.
    The other option is to turn the surf boat into a large sailing canoe with just one out rig hull off one side. I like the design of the old malabu out rigger. I would dearly love to create a more traditional outrigger witha lateen style rig. The hull lends itself to this- it woould look absolutly beautiful. Not a high performance tri (but who cares I am 51 and slowing down a bit) but something very pretty.
    My heart is l;eading me this way even though building the tri with the hobie rig would be easier because I don't have to build the rig (which scares me)

    out rigger surf boat

    Dear Boat Fan- thanks for you encouragement- and you are right.
    The only thing that worries me is getting the rig right.
    I will start up another thread around that next week.

    The main hull (surf boat) is starting to look great. I have just stripped and varnished the teak gunnels and red cedar decks and seats- she is a very pretty boat.

    surf boat out rigger

    thanks for that- you are right

    The only thing that I am worried about is building the rig.
    I am going to set up a new thread on this forum to help work out how to approach it.
    I have fixed up the tatty old teak gunnals and red cedar deck on the main hull and it is looking really nice- I am getting more motivated as the project moves forwards

    I am envious surf boat man ! :D

    You have got an advanced start to a very , very nice build.

    If I could find a hull like that , I would not hesitate to make a serious effort to produce something very easy on the eye.:rolleyes:

    A traditional looking rig would be the way to go IMHO.

    I would look toward the Malibu Outrigger :

    Don`t forget you have a superior hull than that already , at least in terms of roominess , you can sit IN your boat instead of ON it.:)

    I`m sure if you think about it a while ,it will all come together .

    nice one

    Thanks for the pics Boat Fan- nice boat!

    This is exactly the direction that i want to go in. building the outrig arms in timber and putting on a simple rig.
    You are right I have a great platform to start with in a surf boat. I can't believe there are not more of these surf boats conversions around. I haven't been able to find anything on line- all I have is a distant memory of one I saw in the Brunswick river 15 years ago and it was absolutely gob smackingly gorgeous.

    Do you have any pics of your sail and the full rig- thats the bit that I am having trouble

    It`s not my boat surf boat man, it`s a Malibu outrigger.

    You could build a simple box section mast fairly easily.

    A boat designed in the fifties by Warren Seaman.

    Most were home built. ( very simple hull shape ).

    You can actually still get plans for $ 50 : 00 US

    This is their Yahoo group Easy to join )

    And this is the link to those photos in above post, and other pics :

    Warren Seaman actually built a version around 36 ft ? long:D

    I almost forgot surf boat man :rolleyes:

    You could go with a high peaked standing , or balanced lug rig too.

    In my humble opinion it`s a good choice for your boat , because :

    1 : Your spars would be shorter .

    2 : Easier to rig up.

    3 : Rig would stow inside boat , easily.

    4 : Easy reefing

    5 : Cheaper to build.

    6 : Looks , and is traditional.- suits the look of your boat.

    If you want to go this way here is a good place to start :

    You can make the sails for a lug rig too , it`s not that hard to do :

    surf boat rig

    Dear Boat Fan

    I can't thank you enough for your feedback and for sharing your research.

    I love the last rig link- the 24'tacking sail- it looks more the business if you know what I mean.

    I will keep in touch and let you know how we go and post some pics.

    I wlll be away on a month or so- First down the far south coast of NSW then India (if i see any interesting boats there take pics and post them).

    Anyway I will come back to this thread when I am back- Or I might start a new one for this project and any interesting indian boats that I see.

    For now thanks again and happy boating!!! You certainly do have the spirit of a true boat fan!


    BTW- here are some of my fav boat sites- just in case you haven't seen them-
