    I've been shopping and this has really caught my eye. http://www.yachtworld.com/core/listing/boatFullDetails.jsp?boat_id=1425626

    Yes it's big, actually just the right size for the want list and it reminds me of a floating chev suburban, plus it has a bike garage!!!

    The bow bulbs and the steel keel were retrofitted a year or two after launch from what i have been able to find on the owners site. Which brings me to the big question... would these additions really improve the sialing capabilities of this vessel with the length, beam and weight this thing carries? She seems to be sitting higher on the waterline with the bow bulbs now.

    There are quite a few pictures and a survey here ... http://www.adweb.as/TIRAMMEN.HTM

    Thanks for the input.

    Hi Dave,
    Heading to the costa blanca area of Spain at the end of the month, but this thing is 900km away from where I'll be so it will be a bit hectic, but I'll try to fit it into the schedule. There's an early spring trip in the planning too.

    After spending some time on the owners site and doing my best at translating norwegian to english, the bow bulbs were added to lift the front a bit and keep her from heeling a little too. He designed and oversaw the building of it, and designed the remedial changes after she was launched.
    I agree it's heavy, 1" Divinycell H60 and a lot of 'glass. The little bitty keel he added for some reason, (I haven't figured that out yet) is 1" plate steel bolted up through the hull and an additional tonne. Yikes! Did you read the survey? http://www.adweb.as/BEGGE5.JPG

    It looks like I'll be able to gut it and get the interior refitted to suit my tastes fairly easily. Minimum amount of electronics on it too, so I'll be adding quite a few items if I buy it.

    She definitly is one-off which is the way I think anyway.

    Owner is traveling now so he only sent back a short email, maybe more info will show up later.

    Mark

    So i'd have to ask, why would you want to buy a boat that obviously didn't work first time around, then got heavily modified and may not be right now ?
    [ Being kind here, i'd say it's definetly not right ]

    All the multi's i've been involved in use H 80 Divinycell not H 60.

    Looking at survey it says H80 used

    Those bulbs out the front will hook up on the anchor chain.

    Remember weight is the killer in all Multi hulls.

    It does seem a lot of boat for the money and it has got the miles under the keel according to the blurb, but it doesn't feel right from here.

    Also remember the surveyor is being paid to say nice thing's by the owner, it would be interesting to see what YOUR experienced MULTIHULL surveyor says.

    Sorry, i'd reckon it may be more trouble than i'ts worth to get modified and working imho.

    Dave

    Dave,
    That's exactly the kind of input I wanted to hear. Gut reaction and "doesn't feel right from here" from someone knowledgeable is why I started this thread. I would buy it because he has been refining the design. Trial and error on a unique hull design, though it seems thought out.

    I'm trying to put myself in Follestads shoes without having sailed this thing, and come up for the reasoning behind it. The center bulb was the first addition and is submerged. The two outside hulls were added to possibly give her more waterline and counteract any hobby-horsing, or because the center bulbs shape looks like it would pull the bow down instead of providing lift. Then the add-on keel. Hmmmm....

    So I read the threads around here and come across these two http://www.boatdesign.net/forums/showthread.php?t=14860 and http://www.boatdesign.net/forums/showthread.php?t=13569
    I'm having a hell of a time estimating some of the numbers on this thing.

    She's seen 15kts in a blow, so I don't think its under sheeted, but only 9kts at full throttle, that makes me wonder how much drag is happening. Maybe it needs a jato backup out the back door. I'm not looking for speed, Mrs leadfoot has that department covered with offshore powercats, she just can't get enough galley in them and I gave here a rough idea on operating/fuel costs, so she's content with the space criteria of a sailing cat or in this case tri.

    Setting the anchor(s) shouldn't be a problem and hopefully she's built well enough that a little rub won't break them off.

    I’m still waiting for some answers from the owner.

    Thanks, Mark

    BTW I like your rudders in the Spitfire thread.

    Thank's for the rudder comment's, we like 'em.

    I doubt you'll break thise bow's of with the anchoring gear, but they will get chafed and gouged by rope and chain, and be noisy when this is happenning.

    Can't get enough galley in your powercat ?? You've got the wrong type of cat, our galley is 3300 x 2400 in size.

    Use too much fuel in it ?? See above. We are doing a 50 x 24 powercat with 65hp x 2 and should use around 1 litre/nm at 10 to 12 knot's and get around 14kn on the fly.

    Have fun

    Dave.
