Watersports Rentals Industry Terminology

Add-on Revenue

Income generated from optional extras sold alongside the base rental (e.g., tubes, coolers, GoPro mounts, delivery, insurance waivers). Increases average order value and margin without adding core asset hours.

- Bundle a towable tube and rope as a $25 add-on per rental. - Offer dry-bag and phone case packages at checkout to lift ancillary revenue. - Sell late-return protection as an optional fee to increase ticket size.

ADR (Average Daily Rate)

Average revenue earned per rented day for a category or fleet. Calculated as total rental revenue divided by total paid rental days; used to benchmark pricing and yield.

- Our ADR rose from $185 to $205 after implementing weekend surcharges. - Compare ADR by channel to evaluate OTA performance vs direct bookings. - Use ADR trends by month to forecast peak-season pricing.

Beam

The maximum width of a vessel at its widest point. Influences stability, capacity, slip requirements, and handling.

- A wider beam on the pontoon improves stability for novice renters. - Verify the slip width can accommodate a 9'6" beam. - Beam affects trailering mirrors and lane clearance on narrow roads.

Beaufort Scale

A standardized scale (0–12) that classifies wind force by observed sea conditions and wind speeds; commonly used in marine operations and safety decisions.

- Suspend SUP rentals when winds exceed Beaufort 4 (11–16 knots). - Set your weather hold threshold at Beaufort 5 for PWC. - Train staff to describe wind conditions using Beaufort terms to guests.

Bilge Pump

A pump that removes water accumulated in the bilge. Can be manual or automatic; critical for safety and hull integrity.

- Check automatic bilge function during check-out inspection. - Instruct renters to report a constantly running bilge pump. - Replace a faulty float switch if the bilge fails to cycle off.

Boater Education Card

Proof of completing a state-approved boating safety course; often required to operate certain vessels or engines, especially for younger renters.

- Verify the renter’s Boater Education Card where state law requires it. - Offer a temporary boater certificate course link in confirmation emails. - Record card numbers in the PMS for returning customers.

Capacity Plate

A U.S. Coast Guard label stating maximum persons, weight, and horsepower for a vessel. Legal and safety limits that must not be exceeded.

- Deny adding a seventh passenger if the capacity plate lists 6 persons or 900 lb. - Photograph the capacity plate during orientation to emphasize limits. - Use plate data to set booking caps in the PMS.

Cavitation

Formation and collapse of vapor bubbles around a propeller or impeller causing vibration, noise, and loss of thrust; can damage blades and reduce performance.

- Advise renters to avoid weeds to reduce impeller cavitation. - Cavitation damage noted on impeller—schedule service. - Diagnose loss of thrust at high RPM as possible cavitation.

Channel Markers

Aids to navigation (buoys/daymarks) that indicate safe water, lateral boundaries, and hazards. In Region B (U.S.), red on starboard when returning from sea.

- Train guests on Red Right Returning when re-entering the marina. - Mark no-go zones beyond the green cans on the renter map. - Remind PWC riders to stay within the channel at low tide.

Check-in/Check-out Inspection

Jet Drive

A propulsion system that uses an impeller to create a water jet rather than a propeller. Offers shallow draft and unique handling characteristics.

- Recommend jet-drive boats for shallow rivers to reduce prop strikes. - Explain different handling vs outboards during orientation. - Market jet PWCs as safer around swimmers due to no exposed prop.

Liability Waiver

A legal document where renters acknowledge risks and release the operator from certain liabilities. Often paired with assumption-of-risk and indemnity clauses.

- Require all operators and passengers to sign a waiver before boarding. - Use digital waivers with ID capture for enforceability. - Update waiver language to reflect new tow-sports offerings.

LOA (Length Overall)

The maximum length of a vessel measured from the foremost to aftermost points, including attachments. Impacts storage, docking, and regulatory limits.

- Price slips by LOA plus overhang for accurate billing. - Confirm LOA for trailering permits and storage quotes. - LOA affects which launch ramps are practical at low tide.

Maintenance Interval (100-Hour Service)

Scheduled service based on engine hours (e.g., every 100 hours): oil and filter changes, inspections, lubrication, and adjustments to maintain reliability.

- Rotate boats out for 100-hour service during midweek lulls. - Log completed items (oil, filters, plugs) in the PMS maintenance module. - Align service intervals with seasonal demand to minimize downtime.

Maximum Persons/Weight Capacity

The safe limit of people and gear a vessel can carry, as specified on the capacity plate. Exceeding it risks capsizing and legal violations.
