What was an RAF crash tender?
RAF marine craft included fast motor boats kept at coastal and waterside air stations to respond to aircraft accidents on or near the water. These are the boats usually called RAF crash tenders, or “crash boats”. They were part of a wider family of RAF rescue and support launches. They were fast, hard-chined boats, usually in a grey or similar service finish with RAF markings, and several British yards built them, Vosper among the best known.
For modellers, their appeal is a sleek planing hull, a compact superstructure and a strong link to post-war British model boating. Crash tenders were a favourite subject for kits and toy boats in the 1950s and 1960s.
Boat or truck? Avoiding a common mix-up
“RAF crash tender” also describes the fire and rescue vehicles used on RAF airfields, and there are many die-cast and white-metal models of those. Auction and marketplace listings don’t always make the difference clear. If you’re after a boat, check the listing for a hull, a propeller or the words “boat” or “launch”, and look at the photos rather than relying on the title.
Vintage RAF crash tender models you’ll come across
Wooden kits
The best-remembered British crash tender kit is the wooden Aerokits model from the 1950s and 1960s, a sizeable kit of around three feet long that many modellers built as their first powered boat. For other classic British makers of the era, see our guide to wooden model boat kit brands. Kits like this typically came with:
- Printed or pre-cut wooden frames, keel and sheet for the hull
- Full-size plans and instructions
- Some fittings, though motors and electrics were usually separate
Ready-built plastic electric boats
There were also factory-made plastic models of Vosper-type crash tenders with small electric motors, sold ready to run rather than as kits. The best-known were made by Victory Industries. These turn up on auction sites, sometimes boxed, and are collected as much as sailed.
Modern reproductions
Some classic British boat kit designs, including crash tenders, have been reissued as reproduction kits by specialist suppliers. A reproduction is a good choice if you want the look of a period model without risking a collectable original. Modern laser cutting often makes them easier to build than the originals.
Buying a vintage kit or model: what to check
For an unbuilt kit:
- Is the box complete? Ask for a photo of the contents laid out against the parts list.
- Are the plans and instructions present? These matter more than most parts.
- What state is the wood in? Look for damp, warping or brittle sheet.
- Are any parts already started or cut? This affects value to collectors.
For a built model or ready-made boat:
- Check the hull for cracks, soft spots or poorly repaired damage.
- Find out whether the motor and running gear are original, and whether they work.
- Look for missing fittings, especially windscreens, masts and small deck items.
- Check whether the paint is original or a later repaint.
Prices vary widely with condition, completeness and whether the box survives. Compare several recent sales before bidding.
Building an old kit today
You can build a vintage wooden kit with modern materials without spoiling its character:
- Glue. Modern waterproof wood glues and epoxies are more reliable than period adhesives.
- Sealing. Seal the hull inside and out. A thin layer of glass cloth and resin on the outside adds strength and waterproofing. See how to waterproof a wooden model boat hull.
- Electrics. A small modern electric motor, speed controller and 2.4 GHz radio will be far more reliable than period equipment. Our radio control setup guide covers the basics.
- Hatches. Make sure you can reach the electrics through a removable deck or cabin.
A planing hull like a crash tender’s needs its weight kept well aft of the bow and the batteries placed carefully. For similar fast hard-chine subjects, see classic power boat models. Trim it on the water before fixing anything permanently.
Restoring and re-powering a vintage model
For an original model, decide whether you’re preserving it or using it:
- Preserving. Clean gently, stabilise loose parts and keep original paint where you can. Store any original motor or fittings you remove.
- Using. Fit new electrics in a way that can be undone, such as screwed mounts rather than glue, so the model could be returned to original later.
Avoid stripping original paint from a rare model unless it’s beyond saving. Original finish is often a large part of a collectable model’s value.
Painting and markings
Crash tenders were usually painted in an RAF service scheme with roundels and identifying numbers, and the details varied between boats and periods. Our guide to model boat transfers and decals covers sourcing and applying markings. Use dated photographs of the boat type you’re modelling. If you’re restoring a kit, the original box art and plans show what the maker intended. Our guide to painting accurate lifeboat livery covers masking and decal techniques that also work for service markings.
Collecting versus sailing
Many builders keep an unbuilt original kit as a collectable and build a reproduction to sail. Others are happy to build the original and enjoy it on the water. Neither is wrong, but once a kit is built its collector value usually changes. For more on getting a powered model running well, see our guide to radio controlled lifeboat models.
