A water-sports chase boat is the role most often confused with "tender" and most often under-specified. The job is real: tow a wakeboarder, drag a tube, launch jet skis, recover a paraglider, retrieve a foiler, follow a kitesurfer, and spot a freediver. None of those is a tender's job. All of them are operationally distinct, and any one of them done badly is the kind of incident that ends careers and insurance policies.
What the role demands
A water-sports brief breaks into two camps: tow sports and freedom sports. The spec follows the camp.
Tow sports (wakeboarding, waterskiing, tubing, wakesurfing) need:
- A tow point at the right height (usually a tow tower or pylon, not a stern eye)
- A flat, predictable wake at 22 to 28 knots
- A spotter seat with line-of-sight to the rider
- A stable platform for the rider to board from the water
- Engine response that's smooth on throttle, not on/off
Freedom sports (kite, foil, jet ski, paragliding, freediving) need:
- A boat that can stop quickly and stably
- A swim platform low enough for an exhausted athlete to climb onto
- Clear deck space to land kit (kite bars, foil masts)
- A tower or elevated spotter position for visibility
- The ability to operate at displacement speed without porpoising or overheating
The two are largely incompatible in a single hull. Most superyacht programmes carrying a serious water-sports brief end up with two boats: a chase boat for the freedom sports and a dedicated wake boat (Mastercraft, Malibu, Centurion, Axis) for tow sports. The wake boat lives on the shadow vessel or in the parent yacht's secondary garage.
Why a tender doesn't do this
A tender is optimised for guest transfer: dry, comfortable, looks good alongside the parent yacht, generally too refined to drag a tube through breaking surf at 25 knots. A water-sports chase boat is a working platform: a bit rough around the edges, capable of turning sharply at speed, with a deck you can hose out. Trying to do tow sports off a limousine tender is what produces the cracked teak, the stained upholstery, and the awkward conversation with the guarantee broker.
Spec essentials
For a chase boat that has to handle the range of water sports a typical guest week throws at it (freediving in the morning, foil session at lunch, wakeboarding in the afternoon, jet ski tow back at sunset), the working spec we land on most often:
- 9 to 12m hull, twin outboards 250 to 400hp each
- Stainless tow tower with bimini, board racks, and integrated speakers
- Swim platform with telescopic ladder, rated for foiling kit
- Bow thruster (helps with shallow approaches and station-keeping for kit drops)
- Hydraulic anchor windlass (because freedivers want the boat held in position)
- 240V inverter for charging (foil batteries, action cameras, kite pumps)
- Clear deck plan with under-seat storage for kit
This is closer to a sport tender brief than a chase-boat brief, and the line between the two genuinely blurs. Wajer, Pirelli, Ribco, and Sacs all build hulls that satisfy 80% of the water-sports brief in tender form.
Operating realities
A water-sports chase boat is operated by a deckhand or watersports instructor with a Powerboat Level 2 ticket as a minimum, and ideally a tender driver's license or equivalent. For tow sports a separate spotter is required by most flag-state interpretations of MCA Workboat Code (and by common sense; a single person cannot drive and watch a wakeboarder safely).
The boat usually carries:
- A throw rope and rescue equipment
- A spinal board (for foiling and kite incidents)
- Spare props (jet ski strikes happen)
- Tow ropes in two lengths
- Kit-specific safety gear (impact vests, helmets if guests want them)
Insurance terms tend to be specific. Most underwriters want named operators, restricted activity hours (no tow sports after sunset), and exclusions for high-risk activities like parasailing unless the operator carries dedicated sub-cover. We've seen claims declined because the spotter wasn't on the boat for a wake incident.
Cost and where it sits in the fleet
A capable water-sports chase boat in the 9 to 12m bracket lands at €350,000 to €750,000 fully rigged, plus €40,000 to €80,000 of toys (foils, boards, kites, jet skis) that the boat has to carry and service. The boat is usually the most-used asset on the parent yacht in any given charter week, with engine hours that match or exceed the principal tender. Spec it for that.
If you're building toward a serious water-sports programme, start with the activity matrix (what gets done, how often, by how many guests) before you start with the hull. The matrix tells you whether one boat or two is the right answer.
