We used to fit a cover over the chute and tape it down – water also came in through the bowsprit hole, which you don’t have. And of course transom flaps would let in water – when the boat was going at a reasonable speed but not planing – so again we taped these up.
As for water over the foredeck we thought the World was a dryer boat.
Since there are no bilges in the World the crew is standing/sitting in any water that does get in – hence the need for bailers.
