The Dhow
Ga naar:
Nederlands
Building of the dhow started in Mwanza, Tanzania, October 2004. It got launched February 5, 2006, and was sailed to Jinja, Uganda and finished there in the following months. It is basically of Mwanza (Lake Victoria, Tanzania) traditional make (other Mwanza dhows), but 18 m, some 30% larger than the largest ones you see. There is standing headroom under deck. Traditional dhows do not usually feature a deck, and lack stiffness, leading to a heavy repair, caulking, and painting schedule. Built under supervision of owner and resident Bert Hamminga, apart from the deck a host of other non traditional stiffener contructions were added. The dhow can be operated by tree sailors, at least two of which should be experienced in dhow sailing and Victoria Lake conditions. It can host 9 people comfortably at long trips. We sailed all round the lake, a trip of 1325 km without any problems (see: The Big Round). As far as we know, this dhow is the only long range yacht on Lake Victoria.. The dhow is a pure sailing ship. It has no engine. The easiest option for adding one is mounting a 70 to 80 Hp outboard on a removable stern support, for which we can supply a scheme..

Maintenance

mninga, this dhow, enhanced with
non traditional wood and metal stiffener contructions, in stiffness and
firmness meets Western
wooden ship standards.

Swimming:
Owner
Bert Hamminga
has been swimming in Lake Victoria for more than three years now during five
times a day both from the dhow and from beaches and never contracted bilharzias.
If you do, there is a simple medicine that with certainty kills 100% of the
parasites. The pills (an amount per kilo of bodyweight) are quite easy and
harmless and can be taken just for safety, every half year, in one portion.
Other diseases in Africa
None of the many lethal health dangers of the kind falsely reported on western media
are serious threats. What they show is what happens if you do not have the very little money for the easy and harmless cures there are for everything.
In particular, it is recommended
not to take any permanent malaria prophylactics but hold a set of
malaria drugs in
stock for the case you contract it. Sailing on the lake In a dhow, far from medics,
as in similar environments anywhere in the world, one needs a well thought of
set of drugs and
acquire some knowledge.
