Notes
- The X-114 was RFB's six-seat reverse-delta aerofoil boat, evaluated by the West German military; one was built.
- The file is a 12.80 × 7.00 × 2.90 m box (Wikipedia, Jane's). Another table gives an 8.77 m span, so span differs by source (the 7 m figure also appears in a 1977 RFB bulletin).
- Marked secondary.
- True size, no printing tolerance added. Only published numbers are used; anything not published is said so.
- Secondary source: the numbers come from a retailer or magazine copy of the maker's specification.
