    Default Waller TC 670

    I have noticed some chatter around different threads about the Mike Waller's TC670, We have decided that this is the project for us. Is anyone else out there working on one of these or better yet sailed one?

    Hi

    I have bought these plans but did not start yet for a few reasons.
    One of them is that I already have a boat ( 22ft heavy polyester classic gaffer ) and I am not shure I want to sell that one.
    An other reason is, that it's so quiet on the web about this design and I still do have my doubts about the overall "seaworthy-ness " of this small and relatively narrow cat.
    I live in the Netherlands and in general the bigger inland and coastal stretches of water can be pretty severe in bad weather.
    About the design itself; I just love it ! Very clever designed and building looks pretty simple ( if you have some experience ) .

    Hi Ybbon,

    Can't say I have seen it in the flesh but I will give a plug for Mikes plans. The ones I have seen are very comprehensive. Have you spoken with Mike yet? He could put you in touch with other builders to get the info you need.

    regards,

    I hada look at this design too. I liked it but after talking to Mike decided against it for where we were at the time, he suggested it was more for sheltered waters due to the beam

    Hi

    We used to have bigger boats but marina fees & boat maintenance beat me so we looked for trailable comfortable sailing. SO I've been slowly building a TC 670 for 2 years now (hull nearly complete). Being an ex pom, 22ft is quite OK (to me) for Qld coastal waters & the design is great for our needs. Mike Waller did suggest it was for short trips only, but hey, just take more food & water. Re costs - I did find some useful suppliers but that was 2 years ago.

    HI All,

    If anyone with a plan set will send me the material spec's, I will do a costing for materials.

    Ex BNE .

    I have looked at a few of Mike's designs and I believe that his work is very good , and his advice that the TC6.7 design , is best suited to short coastal trips, has merit.

    Ross Turner many years ago (30+), sailed from North Queensland to Brisbane, in a J5 with his wife & 2 young boys, I believe that he did sail in to harbour most nights.

    This may be a bit late coming, since I have just joined this site.

    The comments above are correct. I always recommend that the TC670 is for sheltered and semi sheltered water only, and not for open water. It shares this in common with all narrow beam cats, such as the Jarcats, regardless of what some designers might say or what has actually been done with them. A TC670 has been sailed solo up the Queensland coast, but the sailor was highly skilled and he picked his weather. All nights were also spent at anchor.

    Several TC670s have been built wider - This gives more stability and they are still trailable under wide load limit laws (in Oz, at least). In fact, the standard boat is more stable than it seems, because the Hobie style outrider seats let you get a couple of hundred Kilos of (Bum) ballast much further outboard in stronger winds. Only one has ever capsized (to my knowledge) and this was in a gust measured at 100 kph by the nearby airfield. Notably, an identical TC670 sailing in company did not capsize, and they righter her and sailed her home. In the final analysis, safety in these narrow cats is more about the common sense of the crew than anything else. I have had several queries from builders wanting to make her into a blue water cruiser and I have tried to dissuade all of them.

    I don't normally cost designs. I used to, but it was pointless. The cost varies enormously depending on where in the world you are, what materials you buy, and who you buy from. The only way to get an accurate costing is to get the materials list, choose your materials and suppliers, and do a costing in your local area.

    Bloggs 1968 is right - I'm always happy to answer questions. ([email protected])

    Welcome aboard Mike.

    I am indeed one of the ones you tried to persuade and I thank you for it.

    for those considering this build Mike's study plans are extremely good value (still have mine, in the one day you never know draw )

    they give you a very good idea of what is involved in the build, how it all works and what materials are needed.

    As I said it wasn't for me at the time but a very good design for it's intended use.

    Hello everyone!

    My name is Greg,

    I am very interested in buying the plans and start building the TC670. The problem is that I live in the Canary Islands and I want to navigate between islands, they are open waters where I want to use it.

    My question is ... is there the possibility of modifying any part of the design to adapt it to those characteristics?

    Same helmet construction process as the 880, mast size...

    The TC670 is beautiful and has the maximum dimensions that I can have ...

    (sorry for my English)

    Thank you very much and greetings to all!
