Well, this is an old school track so how about we honor the old school ‘adventures’ that made racing so dangerous and exciting?

1. The water spraying at unknown intervals as you mentioned
2. Force all the drivers to drink a pint of whiskey and smoke a cigar before they are allowed to enter their cars
3. Make the guardrails out of bails of hay
4. Make sure that the runoff areas are running off into the harbour
5. Mandatory faulty wheel nut, you just do not know which of the four it will be
6. Helmets made from leather
7. No visors allowed, just a ray-ban clubmasters

Perhaps if we introduce these rules the race will become more entertaining?
