## Specifications
- Length: 6.6 m
- Beam: 42 cm
- Deck height: 33.5 cm (estimated)
- Layup weights: Cork composite 14 kg
- Usually paddled by: Paddlers in chop

## Ratings (Surfski Index estimates)
- Stability band 4–6 out of 10 (dimension estimate, low confidence).
- Speed rated 6 out of 10.

Modelled from published beam, length and deck height. Low confidence. Speed is our rating. Both are given at the hull's own design weight.

These ratings are Surfski Index estimates, worked out from published dimensions, traced hull shapes where we have them, and reviews. They are not supplied by the maker or timed on the water. How a ski feels depends on your weight, skill, set-up and the conditions, so use them to shortlist skis and paddle one before you buy. Method: https://surfskiindex.com/how-it-works/#limits

Evidence note: This band is estimated from published dimensions. Qualitative context includes 2 paddler reports and 1 linked source.

## Paddler weight
Estimated sweet spot 75–88 kg, broader estimated guide 61–91 kg. An estimate from hull dimensions, not the designer's intended weight.

## Suits
Strong downwind with excellent directional stability ('as though on rails') and good upwind manners; weakness is a wide turning circle, more felt in round-the-cans racing.

## Hull
Identical hull shape to the Surf70 Pro (diamond-section high-volume bow, flat-ish rocker, narrow catch) with a cork/foam composite core in glass or carbon skins for a lighter, more impact-resistant finish. Same triple bullet-scupper drainage.

## What works
- Distinctive eye-catching finish
- Cork core notably more impact/ding resistant (hammer-test demo)
- Rock-solid directional stability downwind
- Very rigid three-point footplate
- Same fast-draining bullet scuppers as the Pro

## Trade-offs
- Widest turning circle of the reviewed Red7 range - handicap in round-the-cans racing
- Rudder cables reportedly stuck/needed replacing on reviewer's boat
- Long-term cork-core durability unproven at this age
- Brand and both third-party makers no longer producing it

## Generations
- 2009-2011: Cork-composite 'eco' variant of the Surf70 Pro hull, built after Red7's factory fire - glass by Republic Sports, carbon/cork by Carbonology Sport. Same hull/handling as the Pro; last genuinely current Red7 product before dormancy.

## What paddlers say
- Rob Mousley (surfski.info, 2010): 'one of the nicest boats I've ever paddled', praised comfort/drainage/directional stability, only gripe wide turning circle.
- Hein van Rooyen (Carbonology Sport): demonstrated cork panels' dent resistance vs standard foam-core with a hammer test; cork dents shallower and largely self-recovered.
