The Ultimate SIB Checklist: 10-Minute Pre-Season Driveway Prep
10 Minute SIB Pre Launch Guide
🕐 Read time: 3 minutes
You've got your boat out of the boot, and you're ready to go, or are you? Spending just 10 minutes in your driveway now will save you hours of frustration later. This routine helps you avoid the dreaded "car park repair session" by identifying issues before you ever leave the house.
Before you trust your SIB on the water, you need to check the hull's integrity.
Fold Line Check: Unfold the boat gently and inspect the lines where the fabric was creased during storage; these are common spots for stress marks or pinholes.
The Transom Bond: Inspect where the wooden or fibreglass board meets the tubes.
The Glue Test: Pull gently on the PVC holders. If there is any lifting or peeling of the glue, it must be professionally reglued before mounting an engine.
24-Hour Pressure Test: Inflate the boat to pressure and leave it for 24 hours; if it is soft the next day, you have a leak.
Pro Tip 💡 When checking for leaks, don't forget to inspect the bottom of the hull and the underside of the tubes for any scrapes or abrasions picked up from last season's beach landing.
2. Valves, Flooring & Bungs
Small leaks can lead to a boat full of water if not caught early.
Soapy Water Test: Remove the valve caps and spray soapy water around the edges. If you see bubbles, use your valve spanner to tighten the core.
Floor Check: High-pressure air decks should inflate to a rigid state with no twists or bubbles. For aluminium or wood floors, ensure side stringers are straight and free of corrosion.
Drain Bung: Verify the transom drain bung seal is intact; a leaking bung will quickly fill your boat with water.
Pro Tip 💡 Keep your valve spanner and a spare drain bung in your onboard "essentials" dry bag so you're never caught out if a minor leak develops while you're away from the slipway.
3. Engine, Fuel & Safety Systems
Avoid a motor that won't start when you're already at the water's edge.
The "Latte" Oil Test: Drain the engine and gearbox oil. If the oil looks milky like a latte, you likely have a water leak and should call a marine engineer immediately.
Fresh Fuel: Replace old fuel with fresh Super Unleaded E5 to protect your engine components.
Connector Inspection: Check the O-rings on your fuel line connectors for cracks or perishing that could cause leaks.
Kill Cord: Check that the lanyard isn't frayed and the plastic clip isn't brittle. Ensure the mechanism releases instantly when pulled.
Pre-Launch Run: Always test the engine in a tank or on flush muffs before placing it on the boat.
Pro Tip 💡 When testing your engine on flush muffs, ensure you see a steady stream of water from the "tell-tale" to confirm your water pump impeller is working correctly after its winter break.
4. Essential Kit Audits
Don't get caught out without the right safety gear or repair materials.
The Glue Test: Open your repair kit; if the glue tube is rock hard, replace it immediately.
Life Jacket Inspection: Squeeze foam vests to ensure the foam isn't compressed. For auto-inflate jackets, ensure the gas cylinder is tight, full, and free of corrosion.
Sizing: Ensure you have the right size for everyone, especially if the kids have grown over winter.
Paperwork: Verify that your insurance policy hasn't expired and check the specific licensing requirements for your destination. Read our blog here: Do You Need a License for an Inflatable Boat
