Trouble in Paradise?

 

Yep, 2morrow is the day.. Wildcard going out of the water and thus we will see how bad Wildcards bottom is.. The hull has a leak, but unknown where or how many and why.. Back stay, runners etc are off so when W is out of the water a crane can come along side 2 take mast of.. 
 

 
Rigger Jason Corall got info about mast: Has been sleeved after it came down in Bass Strait many years ago...
I did have a picture of that I found on internet... 
 


 
More info about the old repair work when mast is down..
 




 
 
 





 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
3 boats were built, and Wildcard and Haphazard were built by 2 brothers on their site in Tasmania,
and they raced each other and changed things on the boats (also masts) and compared results..  as I understand..

A strong, super fast, record holding, Australian built racer/cruiser. She is in need of some loving care, as restoration is due.

WILDCARD was built in Australia in 1994 for the 50th Sydney to Hobart, but designed for the short handed 3 Peaks Race around Tasmania. 

She is still the current monohull race record holder for that race.

WILDCARD was updated for cruising in 2004 and sailed from Tasmania to Darwin.

Another outfitting took place in 2006 in Darwin where she cruised the Kimberley coastline before sailing on to Christmas Island, Cocos Island, Sumatra and up to Thailand.

After cruising around Thailand she was brought to Singapore and used as a day cruiser / live-aboard.

She can be sailed 2 handed and has reached speeds of 26kts on a delivery in race configuration and 19kts during cruising days.

Her ability to traverse great distances makes it a pleasure to sail and give great security, having the ability to avoid or outrun storms. The retractable bulb keel is her most endearing feature having a large fast yacht with incredible stability able to site comfortably in the shallows with the cats making cruising even more enjoyable.

Radford 14m Racing Yacht - Design # 36

was commissioned by two experienced Tasmanian yachtsmen who wanted new yachts for offshore racing and cruising.
They have traded up from their Adams 13 Metres which Graham Radford had earlier successfully modified from stub keel, dagger centreboard arrangements to lifting bulb keel yachts - giving a noticeable improvement in stability and performance at a reduced weight.

The hull of the R14m has a relatively narrow beam, long waterline and light displacement, similar in style to the very fast 10.6m Radford SPRINT.

The bow has flare with fine water lines and a distinct vee in the forward hull sections.

The owners have commented on the considerably softer ride this configuration gives in a seaway compared with their earlier yachts. The vee sections are maintained throughout the hull but are less pronounced aft.

The R14m is designed to carry less than the maximum crew weight allowed under the IMS so has more inbuilt stability to carry the large fractional rig. It is very fast reaching and running, while heavy enough and with sufficient righting moments for fast windward performance - especially in fresh conditions. The point of vanishing stability (not including the positive effect of the house) is in excess of 130deg.

The yacht has a spade rudder and a lifting bulb keel. The vertical lift keel is hydraulically operated. It remains pinned fully down for racing but can also be sailed half raised at other times. For access to shallow waters the keel can be raised to 1.6m draft - just below the rudder depth.

The R14m is not a big volume yacht for its length.

The layout is simple and open and meets the lMS accommodation requirements for bunk numbers, fuel & water tankage and crew & galley stowage - including a large sail stowage area forward. Headroom is 1.9m - 6'3".

The displacement hull speed of 9 knots can be achieved with an engine size of 35-39HP. A speed of 8 knots can be achieved with a 25 29HP engine.

The construction drawings are for aluminum and have A.B.S. plan approval.

The design would be very suitable for FRP / foam sandwich construction. The reduction in construction weight and the use of a duplex S.S. keel foil and composite rudder would further increase the performance of this design.

The large fractional rig has triple swept back spreaders. There is a fourth spreader at the hounds if a masthead spinnaker is to be used. The mainsails on the first yachts have full length battens.

In conclusion,

the R14m Racing Yacht is designed for exciting club racing and offshore PHS and lMS racing and short term, fast cruising.

  • Stability Curves

The following 3 stability curves give examples of the variations in righting arms and points of vanishing stability (PVS) which can occur with different vertical centres of gravity (VCG).

This lift bulb keel racing yacht had an inclination experiment conducted, with the yacht in measured condition i.e. no loading, and the VCG of the yacht was established. The first 2 curves show the yacht with keel fully down and fully raised in its unloaded condition. Even with the keel fully raised, the PVS on this yacht is still 141.5 deg. The bulb keel arrangement gives a very low VCG for the ballast.

The third curve shows the yacht loaded with all of the crew weight and gear weight for racing located at deck height and on centre line. The PVS is still 153.7 deg with keel fully down. The area under the righting arm curve up to 180 deg is very small. This yacht would be difficult to capsize and would right quickly.
