    The Brunswick is a historical wooden shipwreck that lies a few hundred metres off the northern end of Long Beach in Simon’s Town, directly opposite the northern end of the white apartment buildings overlooking the Main Road. Like HNMS Bato, she is infrequently dived. Having lain underwater since 1805, she is heavily overgrown and much of her decking and hull is covered by sand. She used to be a shore entry (with a precipitous climb over the railway line), but in recent years a large number of boulders have been added as a breakwater between the ocean and the railway line, and climbing over in dive gear is no longer possible. For this reason we do the dive from the boat. Close to shore and in shallow water, the Brunswick is an ideal site to get used to boat diving.

    The Brunswick was a British East Indiaman, which means she carried men and goods between Britain and the East Indies – (south)east Asia and India. She was carrying a cargo of cotton and sandalwood from China back to Britain when she was captured by some French vessels off Sri Lanka, and brought to Simon’s Bay. In September 1805 her anchor rope parted, and she ran aground during a south easterly gale. Most of her cargo was salvaged, as she lies in shallow (less than six metres deep) water.

    We found the dive site to be similar to HNMS Bato, which was also a sturdily built wooden ship of similar vintage. The Brunswick was 1,200 tons, and her wreckage is spread out quite extensively. There are many thick, wooden planks, laid out as they would have been to form her decks, as well as much evidence of the bronze bolts that secured parts of the ship together. There are also many copper bolts, rivets and what could be small amounts of rolled up copper sheathing in evidence on the site.

    The highests parts of the wreck are covered with feather stars, anemones, sea cucumbers, and kelp. There are many octopus, and peering under the wreckage with a torch yielded a couple of very large pyjama catsharks. We were lucky to dive the site most recently on a day with lovely visibility, and the shallowness of the water means that there’s a lot of light penetration which improves things enormously.
