Kaikoura Boating Club
Notice of Special General Meeting
To Discuss and Approve Earthquake Repair Budgets
Kaikoura Coastguard Building – South Bay
Tuesday 25th Spetember
5:30pm
All members welcome.
Request for practical ideas on restoration of service to all club facilities.
Hi All,
We have issues at all three of our facilities.
As a committee we are interested in any proposals as to how to deal with them.
We need to extend the ramp at South bay.
Three major suggested ways at present:
1/ Build a coffer damn, pump out water, box and pour in place extending the extra 10m plus covering about 7m of the existing ramp which has some damaged sections. Costed at about $70K
2/ Cut out an repair only the damage sections, box up and pour the extension in the existing ramp, then slide it into place on plastic sliders with digger assist. Uncosted – need a costing.
3/ Cut out damaged areas as in 2, but rather than pouring the entire extension, precast the extension in sections offsite, bring them in and lift them into place with a digger, then pump concrete through holes in the castings to fix them in place. Uncosted – need a costing.
Fixing the new sets of five additional poles on each line and tying them into the sections of ramp at the same time would seem to be the most sensible approach. If you have contrary ideas please let us know what they are and why you prefer them, in as much detail as needed to get the idea across.
Any other suggestions please send to Ted (ted at fishnet.co.nz) and or Neil (stay at lobsterinn.co.nz) urgently.
The more fully costed they are the better.
Similarly at the Pier ramp on the North, and at the Oaro ramp.
Your committee is open to suggestions, and are particularly interested in suggestions from people with real practical experience doing similar jobs.
Quake update
23/11/2016 initially written – updated 11/12/2016
Hi Everyone,
Lots happening here.
As your are no doubt aware, the quake lifted most of this part of the coast.
Our ramps are currently only usable above half tide, and if you have a deep boat only at high tide.
We are exploring possible options.
We are open to suggestions from anyone with experience in such matters (we don’t just want ideas, we have plenty of those here, what we need is options from people who have used those options successfully in the past).
Below are some photos of the ramps at low tide.
We did a brief survey (man walking out with stick with depths marked on it, dragging rope with marks every 5m) of the South Bay ramp last night – a rough drawing of that is also below.
Our ramps are currently on a 1 in 10 gradient.
We have permission from the harbour master to restore our previous level of service – nothing more.
“1. Private and/or small ramp facilities (CG, Boating club, campsite etc.). These facility owners are authorised by me, as Harbourmaster, to undertake emergency works to return the ramps and facilities to the same access conditions you had prior to the quake. This means you can start whenever you can the only requirements being that you mitigate and negative impacts of the work as much as possible. ”
So we plan to extend existing ramps on existing gradients and cut channels until we have the depth of water we previously had at low tide (about 1.2m).
Exactly how that is done is the big question.
There is some possibility of assistance from the army and navy – and that would be lovely if it happens, and lets not bank on it.
The club has a reserve available for repair work, but at around 70K, may not be up to meeting standard contracting rates for such things.
Any assistance club members can bring would be gratefully received.
We have permission to use a nearby abandoned quarry as both a source of rubble for causeway if required and a storage site for material temporarily.
This is a rough map of what needs doing.
About a meter depth of material to be taken from each of the bars.
Could really do with a team of divers to do a thorough visual survey of any potential issues right out to the next reef.
Or anyone with a multibeam sonar to do one at high tide.
Once we get the readymix plant operating again in Kaikoura (30T crane need to set it back on its feet currently), the easiest thing will probably be to close the ramp for a couple of days, build a coffer dam to allow us to work for a couple of hours either side of low tide, pump it dry, and box up and pour the extended ramp. Keeping to current angle (1 in 10) there is about 12m out by 24m wide of slab that needs pouring, with new poles required both middle and sides.
The North slip is much more difficult.
A big shelf of limestone now lies between us and water.
Exactly how we cut that limestone out is the question.
What might lie beyond it is also an open question right now.
Big digger is probably best, and some of the rock may be particularly tough.
A job for very low tides.

Many discussions have been held, some more still to be held.
There is more work to do than our $80K reserves allow for.
We are exploring options, and we will update this page as soon as we have anything firm.
Currently there is about 700mm depth of water at the bottom of the ramp from half tide.
Full tide is around the old half tide level.
