1980s-1990s Assault Era

1982

Michael Reagan

Multiple-engine Scarab

25h 11m

Route

New Orleans → St. Louis

Distance

1,041 miles (upstream)

Vessel

Multiple-engine Scarab

Notable Context

Same Michael Reagan behind the Great Lakes Assault (1986). The Scarab's multiple engines made it a speed platform for river assault records during this era. This upstream New Orleans-to-St. Louis push demonstrated the strategic importance of choosing favorable current direction.

1990

Howard Arneson

32-foot Skater w/ Twin Turbines

12h 40m 50s

Route

New Orleans → St. Louis (upstream)

Distance

1,041 miles

Vessel

32-foot Skater with twin turbines

Performance Context

Destroyed the previous record by Bob Cox (20h 16m, 1987) with a turbine-powered platform. The twin turbines provided sustained velocity over the 1,041-mile distance. This demonstrates the power of propulsion technology as a limiting factor in river assault records.

Chasing Greatness Category

This is an original CG category — no documented record exists for the full Chicago-to-New Orleans run. Previous records (Reagan, Arneson) target the New Orleans-to-St. Louis segment upstream, reversing current advantage. This full downstream route from Chicago represents uncharted speed-run territory.

1,500 MILES

Route Breakdown

Segment 1

Chicago River & Canal

Distance: ~40 miles | Duration: 2-3 hours

Start: DuSable Bridge, Michigan Avenue. Navigate narrow urban river through downtown Chicago, then enter the Sanitary & Ship Canal heading southwest to Joliet. Mostly flat water with slow commercial traffic.

Key: Navigate shallow draft, watch for barge traffic, manage speed in restricted zones.

Segment 2

Illinois River

Distance: ~275 miles | Duration: 14-16 hours

From Joliet to Grafton. The Illinois is fast water with 8 locks between Joliet and the Mississippi confluence. Current assistance throughout. Major fuel stops: Joliet, Peoria. Slightly tighter channel than Mississippi but manageable for speedboat.

Key: 8 locks require coordination; manage lock descent strategy; monitor water levels seasonally.

Segment 3

Upper Mississippi

Distance: ~565 miles | Duration: 24-28 hours

Grafton, IL to Cairo, IL. The Upper Mississippi locks are more frequent (10-12 locks) but water is fast. Major fuel stops: St. Louis (critical point at ~300 miles from start), Memphis. River narrows in places; commercial traffic is heavy. This segment separates skilled operators from tourists.

Key: Lock frequency; heavy barge traffic; St. Louis fuel checkpoint critical; watch for sandbars.

Segment 4

Lower Mississippi

Distance: ~620 miles | Duration: 24-28 hours

Cairo, IL to Gulf. ZERO LOCKS — wide open water from Cairo south. Current runs 1-3 mph average. Fuel stops: Vicksburg, Natchez, Baton Rouge. Final approach to New Orleans passes through swamps and levees. Wide channel allows high-speed running. Finish line: French Quarter riverfront (verification: Café Du Monde beignet + receipt timestamp).

Key: Lock-free speed zone; current is consistent; final fuel push in Baton Rouge; navigation confidence required for swamp approach.

Analysis

Speculation

Lock Strategy

18-20 locks is a significant variable. Illinois has 8, Upper Mississippi has 10-12, Lower Mississippi has 0. A full descent through each lock costs 8-15 minutes (wait, descent, lock clearance). Expert lockmaster coordination could save 2-3 hours. Consider: pre-call locks ahead, maintain radio contact, prioritize speed in lock chamber approach.

Current Assistance

The Mississippi's current is fastest in spring (flood season, 2-4 mph) but ice and unpredictable water make late spring-fall safer. Summer current typically 1.5-2.5 mph. A 30-knot speedboat gains 2-3 knots from 2 mph current, reducing overall time. Seasonal window: May-October optimal. Winter and early spring: avoid.

Commercial Traffic

Heavy barge traffic throughout, especially Illinois River and Upper Mississippi. Tow boats pushing multiple barges are slow but have right-of-way. Speedboat advantage: maneuverability. Overtake in wide sections; expect delays at bottlenecks near St. Louis. Lower Mississippi has fewer congestion points.

Fuel & Endurance

1,500 miles at 30 knots cruise is ~50 hours of fuel burn. High-speed assault likely requires 3-4 major refuels: Joliet (checkpoint), St. Louis (critical), Memphis/Vicksburg (long leg support), Baton Rouge (final push). Each stop: 20-30 min refuel + crew rotation. Plan fuel logistics ruthlessly.

Café Du Monde Finish

Verify finish at Café Du Monde in the French Quarter, New Orleans' riverfront. Route ends in downtown New Orleans riverfront near the Café. Timestamp finish: order beignets, get receipt with time. This location is iconic, accessible, and provides undeniable proof of completion. Beignet box + receipt = official record marker.

Estimated Assault Window

Based on Reagan (1982: 25h 11m on 1,041 upstream miles) and Arneson (1990: 12h 40m same distance), the Chicago-NOLA downstream run could achieve 42-48 hours with optimized lock strategy and favorable current. Downstream advantage over upstream: 4-6 hours. Elite crew, modern 30+ knot vessel, May-June window could push 40-45 hour target.
