2. Pump Out & Purge Waste Tanks

Chicago Park District rules prohibit any discharge—gray or black—within harbor limits and levy fines up to $500 per violation. (files.chicagoparkdistrict.com)
Schedule a pump-out as part of refueling or use the free-to-use stations at DuSable, Montrose, and 31st Street. Close Y-valves and secure them with wire ties so no guest “accidentally” flips a lever.

3. Fill Fresh-Water Tanks and Chill the Coolers

• Water: Aim for two gallons per person for drinking, rinsing, and galley use. Playpen days mean sun and salt-rimmed snacks—don’t skimp.
• Ice: Figure one 20-lb bag per cooler, per three hours.
• Provisioning: Pre-portion sandwiches and fruit in reusable containers; loose wrappers become litter the wind will claim.

Pro Tip: Many charter operators partner with local caterers—order a lunch spread and have it waiting aboard to skip grocery runs.

4. Stock Weather-Smart Wardrobes

Lake Michigan temps often run 15 °F cooler than street level, and storms form over Wisconsin with little notice. Pack:

• Lightweight layers and hoodies

• Rain shells (look for 10 k waterproof rating)

• Boat shoes or non-marking sandals

• UV buffs and reef-safe sunscreen

Wet guests get cranky; dry guests keep dancing.

5. Verify Mandatory Safety Credentials

Illinois requires anyone born on or after Jan 1 1998 operating a motorboat over 10 hp to carry a state-approved boating-safety certificate. (dnr.illinois.gov) Take the free online course—it’s accepted anywhere on Lake Michigan. Charter platforms usually demand proof before releasing the keys.

6. Inspect Critical Safety Gear

Drills aren’t just for coursework: assign a sober “safety mate” to point out exits and operate radios before you leave the slip.

7. Check Notices & Limit Zones

• CPD Harbor Rules: Speed limit 5 kts inside break-walls; no amplified music over 80 dB after 10 p.m. (files.chicagoparkdistrict.com)

• USCG Safety Zones: Fireworks nights close the southeast Navy Pier triangle—anchoring here risks citation and eviction. (federalregister.gov)

• Capacity Caps: Uninspected charters max at 12 passengers inclusive of hired captain and crew. Planning a multi-boat raft-up? Each hull must meet its own cap.

8. Anticipate Crowds & Emergency Services

Recent Playpen seasons saw critical injuries from slips, prop strikes, and break-wall collisions, often linked to over-crowding and alcohol. (abc7chicago.com) Keep an eye on Chicago Police Marine Unit Channel 17 and maintain fender distance in tight anchor fields.

9. Elevate the Experience—Entertainment & Comfort

• Float Pads & Inflatables: Reserve ahead—rental stock runs out quickly mid-July.

• Curated Playlists: LTE can lag; download Spotify or Apple Music sets offline.

• Photo Ops: Golden hour between 6–7:30 p.m. aligns skyline glow behind the stern.

• On-Board Games: Waterproof playing cards, floating beer-pong tables, or trivia buzzers keep groups engaged when wind picks up.

Remember, environmentally friendly toys (no single-use balloons or glitter) keep the water party alive for future guests.

10. Departure-Day Ten-Minute Final Check

1. Batteries at 12.6 V or greater

2. Bilge dry; blowers run 4 min before start

3. Nav lights working (even for day runs)

4. Lines stowed loose and fenders ready

5. Waypoints loaded into plotter

6. Weather radar & NOAA forecast refreshed

7. All guests briefed on life jackets & head use

8. Coolers iced and secured

9. Bluetooth speakers paired; volume test under 80 dB

10. Gate locked at slip—prevent unauthorized boarding

Clip this list inside the companionway hatch; repetition builds safe habits.
