    Try that web site, it has some information on the product.

    cost about $1000 bucks including the Micro-len floatation.....

    Hi Mick,
    Job looks good,neat bit of alloy work.
    And you can still get your toes underneath.

    Re: LEVEL or LEVEL AND UPRIGHT Floatation?

    Yes...I am very happy with the job....I am thinking about fitting some padding along the sides now to rest my weary old legs against...just not quite sure how i am going to fasten them....cheers Mick

    Mick,

    you'd be surprise how strong Velcro is. Even the Black Watchs have bits of Velcro holding some of their hard to fit bits of padded coamings. I am looking at using sail track to keep the padded coamings on, on my next boat.

    Having just spent the last two weeks going round in circles talking to boat builders and marine surveyors, what everyone has talked about in this thread is correct. What Snelly has done is the only way out. Also have a look in the reports section on the DI Pt 9/6/07 report by Firetruck. http://www.ausfish.com.au/vforum/sho...d.php?t=111356 In that the guy has gone out with Ed Falconer who has Keely Rose a boat in Qld 2C to 15Nm survey. To achieve that Ed would have had to have got his boat builder to supply a statement of positive flotation. In the pictures you can see similar to what Snelly has had done but from the gunnel to the floor to achieve the required amount of bouyancy up high. That is what it hinges on, getting this flotation high enough. More than 6.0m and for survey someone would have to do stability calculations.

    Talking to the couple of surveyors I talked to, cats are the conundrum. They will always capsize but to get to that point a lot has to happen. If holed they have two hulls to start with and the clincher is they have self draining decks. That makes a lot of difference and surveyors are forever fighting the authorities over cats being a legitimate proven design for boats required in survey.

    just bought out a new boat design ''twin skin hull'' and i use micro len
    will post pics and the specs ,let me know what you think

    Boston Whaler have true level floation but you pay for it.

    Hi Builder...what do you think of Micro Len as a product....

    Re: LEVEL or LEVEL AND UPRIGHT Floatation?

    I think the whole issue is a bit exagerated and simplistic in respect to safety. Very few boats just get swamped in calm water or get holes in the bottom of the hull and start taking on water. By far the greatest hazard is capsize due to waves, ie crossing a bar, broaching while running with a sea etc etc and in such a situation no amount of floation is going to change the fact that your in the water with a boat that is upside down with no way of righting it. Would recomend a good quality bar crossing course and seamanship course plus good maintenance would go a lot further towards making you and your family safe than any amount of floatation.

    Have you read anything in this Post......

    We are talking about UPRIGHT floatation ........

    And just maybe the sea conditions where other Ausfish members live ...arnt as friendly as yours.....

    Re: LEVEL or LEVEL AND UPRIGHT Floatation?

    Level and upright flotation do not mean self righting.

    So if your boat gets a hole or you leave the bung out and is swamped in the lake it will float with the gunnels just aove the water and you can put the bung in / plug the hole and bail it out. Yipee

    Now for the real world. Boat has flipped. this flotation will not self right the boat to my knowledge.

    Think about how much ballast a yacht has or even how much buoyancy a hobicat has with one of those 15 litre cones on top of it's mast 30 feet up to stop it going turtle but not self right.

    Comments about flotation foam and ability to stop a boat turning over or healing as much are incorrect. Your hull shape determins that. Flotation only comes into play when swamped.


    Hmmm

    Also can't see the fire rating on that foam??

    Your 100% right cormerant in the real world no amount of floatation, upright, level or any other is going to change the fact that you will be in the water clinging to an upturned hull in 95% of situations. Snelly1971 you have no idea of the conditions that I go boating in or my experience as a skipper or my knowledge of boat building and design but you take your boat beam too through a bar and get hit by a wave and I bet your clinging to an upturned hull regardless of your bounancy.

    Hi #########,
    What makes you think that a boat would be upside down in 95% of situations?

    Re: LEVEL or LEVEL AND UPRIGHT Floatation?

    ######### & cormorant are correct in saying, having a "level flotation" capability won't self-right the vessel. 95% may be accurate, haven't seen the figures to comment. a lot will come down to decisions made by the operator at the time, there will be times when exceptional circumstances, planets alighning, that sort of thing will define the outcome.
    it's practically impossible to achieve self-righting in an open or well-deck boat, like most of us fish out of, you'd need flush decks and a heap of ballast, boats similar to one's in a video of the US Coast Guard on another thread. traditional fishing boats just don't have the design to be self righting, they're built to carry loads.
    I'm happy to have reserve buoyancy because swampings are always a possibility. if the seas are such, that they can capsize your boat, avoiding that will be down to the skipper.

    Re: LEVEL or LEVEL AND UPRIGHT Floatation?

    Well all i can say is that i have seen many swamped boats...and 90% of them were upright......as for fishing conditions EC....They dont call it the roaring forties down here for nothing......

    The main reason for myself for fitting above floor flotation is to bring my boat into survey standards...which now it is.....I think the marine surveyors would know a little bit more about buoyance than us.????....

    Cheers Mick
