Diving the Cape Peninsula and False Bay/Highfields
The Highfields was a British four-masted steel barque commanded by Capt E.R. Dunham. The vessel was lost on 14 August 1902 after a voyage from Cardiff to Table Bay with a cargo of coal. Survivors reported that she had been in a severe storm off the Cape and had lost most of her canvas. Her decks were awash but she managed to reach Table Bay under small sails. It seems her crew and captain were desperate to find shelter.
The German steamship Kaiser was at anchor just outside the breakwater when the Highfields came out of the dark (just after midnight) and hit her anchor chain. The Highfields briefly lay across her bows before being blown off. The Kaiser was not damaged at all, but the Highfields sank within 2 to 5 minutes of the collision with the loss of 23 crew including the master and second mate.
This site is not in a Marine Protected Area. A permit is not required. The site is mostly within the traffic separation zonw between the main deepwater channel and the inshore traffic zone and the bows of the wreck extend a few metres into the main harbour approaches lane
The name "Highfields" is the name of the shipwreck at this site.
Maximum depth is about 22m. and the top of the wreckage is about 18m.
Visibility will be at its best during or after strong south easterly winds, and may exceed 20m, but will more likely be around 8 to 10m. If the wind stops and the sun shines for a few days, plankton bloom will reduce visibility, and if westerly winds blow, they will usually also result in poor visibility (could be less than a metre on a bad day).
The wreck lies in roughly 21m on low flat rock between slightly higher ridges to the north and south with small patches of sand and gravel, and is fairly intact but is up-side down so it is mostly hull plating that is visible, Around the sides there are a few places where one can see into or under the hull, and her huge anchors lie just off the bow.
The wreck is aligned almost east-west geographically. The bows are to the east, and a section of bow with the forefoot and a shot length of keel has broken off and lies on the bottom on its starboard side. This section carries the anchor winch, which is quite large and still largely intact. Scattered around this section are several anchors of the traditional shape, some with stocks deployed, others with stocks stowed and a couple with missing stocks. They may not all originate from this wreck, as there are about 6, of various sizes, which seems a bit much, and the area has been an anchorage for centuries, so it is entirely possible that sme of them were from other vessels which were fouled on the wreck and lost.
A short distance further east there is a section of what appears to be the bowsprit, a large diameter iron tube with fittings appropriate to that origin. It is only a few metres long, and is aligned roughly with the length of the vessel.
Slightly to the west there is a rather broken up section which contains a large mass of chain, rusted and concreted by coralline algae and other growth into a solid mass with the other wreckage, and further west the main section of hull has collapsed, leaving mainly low sections of topside plating and frames standing upright to the sides.
Geology: Pre-Cambrian sedimentary rocks, probably of the Tygerberg formation, with scattered patches of sand and gravel. The rock is quite hard and tends to weather in rectangular blocky forms. Strike probably north/south. Dip not known.
The site is usually at it's best in summer but there may also be occasional opportunities in spring and autumn.
This site is only accessed by boat as it is quite far offshore and at the edge of the shipping lane at the entry to Cape Town harbour. Take care to remain outside of the shipping lane.
The site is about 2.2km from the Oceana Power Boat Club slipway
Inverted wreck of a 19th century iron sailing ship. The wreck is in an interesting condition, where it is sufficiently intact for a diver to work out where on the vessel you are, but sufficiently broken up to make this a bit of a challenge. There are several large anchors, a large winch, some fragments of the rig, the rudder, two sets of bollards and some enigmatic pieces of machinery, besides the large amount of hull that is still more or less intact, and the usual scattered plates and frames around the primeter and lying in heaps neare the hull. The wreckage is unusually bare of marine growth for its age, and is largely coated with pink encrusting coralline algae, much like most of the surrounding reef, and in many cases the first indication that you are looking at wreckage is that it has unnaturally straight lines, and space underneath. The hull has several areas where it is possible to see some distanc under the plating, and one wonders what may be found in these protected areas on a day with good visibility.
No specific route recommended. It is possinble to circumnavigate the wreck during a dive.
Diving the Highfields is especially tricky as she lies only a few meters west of the entrance channel to the harbour. One needs to inform Cape Town port control of the dive and then devise an ascent system that prevents divers drifting east into the channel on ascent and while on the surface. A shot line placed on the bow (furthest point away from the channel) with its buoy attached to a second line to an anchor placed about 100m further west has proved workable. Another way is for divers to tie a sacrificial ascent line to the wreck which they hold onto during ascent and on the surface. They then let go of the line once the dive boat gets to them. In any event, diving the wreck with a west wind blowing or with an appreciable current from the west is not advisable.
It is essential to be able to find your way back to the shotline, or deploy an upline and DSMB for ascent, as you must avoid getting into the shipping lane, particularly during the ascent, as at that time the boat will not be able to assist if a ship comes through. Do not assume that large ships will be able to avoid your DSMB, even if they see it. Altrnatives for finding the shotline include bottom lines, and effective use of a compass, bearing in mind that the wreck is steel, and will affect accuracy of a nearby compass. Navigation using landmarks should be possible if the shot is suitably placed, but this will depend on visibility.
The site is not suitable for entry level divers due to the depth and skills requirements.
DSMB is strongly recommended so that the boat can monitor your position if you must ascend away from the shotline. Jersey upline (disposable, biodegradable line for ascent) recommended to prevent drift if ascending away from shotline.
