southward we sailed, the more temperatures rose and with the Tropic of Cancer
behind us we did not need many clothes anymore. Sailing jackets and
trousers almost only came out of the cupboard for airing, or when it was
humid at night.
On the Cape Verdians (15°N) temperatures were still comfortable but
halfway the passage to Suriname, at about 10°N the heat became
overwhelming. Once in Suriname the heat is difficult to cope with. In
daytime temperatures are about 33°C and in the long dry season (August
until November) they rise to 37-40°C. At night the temperatures almost
don't drop. Good isolation of hull and deck now works against you and
inside the boat it is sometimes too hot to be able to get some sleep.
||Of course we
already had our bimini, but this one only protects the cockpit, which is
not enough in the tropics. So we covered the boat with "shadow
cloth". This blocks 80% of the sun but wind and rain still come
through. The result is that the decks underneath are not becoming so hot
anymore. But a piece of tarpaulin is also good or probably even better, as
the 100% windproof cloth creates a wind funnelling effect.
Ventilation is also very important, to prevent from mildew as well. We can
place a windscoop in the forehatch opening, but this does not work very
good on a fast streaming tidal river. Talking about the forehatch, we
re-mounted it the other way round, opening to the front to catch more
In a computer shop we bought two small computer ventilators. We mounted
one next to our bed, and one in the navigation area. They use only 0,015 A
and they work fine.
