    They already have all that infrastructure.

     

    What you are missing is now much they charge the likes of Wild Violet down there, it is beyond nasty and well into the 'brutal' area. Basically they have a monopoly and are abusing it to charge well over the top. For a tiny fraction of their super normal profits they could cover the cost of Violets suggestion. It would be a win for the boater, a win for the environment, a win for the authority claiming to be concerned about the environment and a win for common sense. The hassle of course if most Authorities like that are totaly devoid of anyone who has even the slightest concept of what common sense actually is.

    Okay KM I'll bite. Somewhere else you said you enjoyed numbers

     

    So hypothetically you are a haul-out yard owner and own an expensive travel lift which requires competent skilled operators to operate efficiently and safely... you also own or lease a suitable hardstand and have acquired the necessary consents to permit the safe disposal of various concentrated heavy metals that may be present in antifouling coatings and potential nasty invasive critters, which are washed off in your yard and are your responsibility to dispose of safely and in accordance with the law. 

     

    Because you are such a Good B%%&*&  we won't even worry about the cost of the yard, any consent compliance costs, staff training, PPE  and the like.

    What is your travel lift worth and what is a suitable ROI on an hourly basis given its likely annual use?

    How many lifts do you do a year? How many free lifts do you do a year?

    What about scheduled maintenance on your travel lift?

    What does that cost?

    Do you have any finance on your travel lift?

    How much is your public liability insurance?

     

    What is your hourly rate that you charge your labour unit and the travel lift out at?  Can you afford to give two free haul-outs away to very boat owner free given your fixed costs? 

     

     

    P.S What does it cost for a lift n hold n wash in ALK? for a 30ft Garden Ornament or similar?  Don't disagree that authorities could somehow incentivise recreational  boaters to keep their boats in good order but for free, really?

    Do you really think anyone is going to put Capital into a travelift plus associated breastworks, hardstand, resource consent lodgement and compliance, waste removal, health and safety, environmental management etc for you to have two free haulouts a year?...so you can avoid going scrubbing yor boat clean in NZ's foremost Coastal National Park? What am I missing?

    RNI fuel requirements

    To reiterate I have no problem with achieving the requirements both under Cat 2 safety regs and RNI NOR. I understand perfectly whay the requirment are there. I remain somehwat conflicted as to the safety of carrying circa 120 plus litres of 91 octane petrol on board. This is my issue and ultimately is an economic question probably resulting in moving to a 4 stroke motor. Thanks again everyone.

    Yeah. It is very much a discussion about safety. Thanks for your input. Not everyone has your experience,but rather than make 'dumbo mistakes'

    I want to ensure that I have prepared my boat as best as I can as required by the event and within my budget.

    I think the issue might be doing your range calcs at WOT. That is the least fuel efficient point for any motor. Using 75% or 80 % of WOT is likely to reduce your fuel consumption 40-50%.

    You should still get very good speed and power at 75-80% of WOT. If you don't, there is probably a deeper issue with the suitability of your set up.

     

    Without knowing the specifics of your motor, if you need 140 l at WOT, and you can carry 110 l, then you should be perfectly fine if you determine your fuel consumption and speed at 75% of WOT and re-did your range calcs.

     

    Fish...the boat will do 6.5 -  6.8 flat out in flat water. Will do short test at 5.5 - 5.3kns as per Jon's previous recommendation and recalculate. Thanks everyone for the feedback.

    68nm Changed roughly

    Lucky you were on that side when you needed it not 70nm abeam of Auckland and have to wait a day for the Manukau bar to settle or 100nm north of New Plymouth with 5m swells rolling into the harbour.

    It’s always the ones that haven’t done a RNI that think the requirements are unreasonable

     

    Jon, I don't think the rule requirement is unreasonable at all (having attempted to previously motor upwind in 45 - 50 knts in Cook Strait in a relatively calm sea state)  but exceeding the minimum as per your earlier guidance suggests our current configuration will necessitate carrying at least 140 litres. We are currently restricted as to overall outboard length and width. Transom height is also important but looking at a few figures last night we could easily move from say 5.1 WOT L/hr to a 4 stroke 3.8 Lh/r WOT option and therefore move consumption in line with SMU, KM. or Changed.  The rules are there for good reason based on previous experience invariably gained through varied decision making! We already have capacity to carry 110 litres on board if necessary.

    From memory fuel requirements are based on being able to motor x distance in flat water. (150nm?).

     

    And 20L extra fuel.

     

    Are you saying outboards use too much fuel to motor 150nm to be able to carry safely onboard?

    No - but using Tohatsu 9.8 two stroke figures being  5.1L/Hr at WOT to achieve say 6 knots requires carrying a minimum of 127.5 Litres! Sure can ease back on throttle and do say 5.0 - 5.5  realistic) and probably save a heap of gas and meet requirement - still going to be considerably more than SMU. SMU are you running standard Yamaha 8 - 4 stroke prop or High Thrust?

    Not necessarly diesel related but I note the existing smaller boats will have a mix of inboards and outboards. I have calculated our fuel requirement as rather onerous and arguably unsafe. What (how much)  is everyone else going to carry?

     

    1. Option one - Carry the specified fuel requirement
    2. Option Two - Buy a new motor and re-engineer well :(

    Sailors Corner closing down

    SC advertising their closing sale tomorrow on the radio. Thought the 3 in Westhaven meant competitive prices, that then also applied in Chch with Burnsco. Here the staff can often be next to useless but does that mean minimal wages. Who doesn't Google before going shopping anyway. I spend lots on Amazon. Note none of the premises at the Lyttelton marina have found tenants.

     

    Wow - what a collective of random assumptions. Your glaring lack of understanding of economics 101 is troubling whether it be leasing near shore space, competition or wage structures. Let alone an understanding the potential scale of a particular market where there are significant barriers to physical market entry and little in the way of barriers to virtual entry. Do you really believe that 170 berths is sufficient to support any type of retail, marine related or hospitality business other than a coffee cart?
