Delta Longfuse 770 Fuselage BLEM-Damaged in Shipping

The Delta Longfuse 770 Fuselage is a 770mm hydrofoil fuselage from Delta Hydrofoils, a U.S.-based foil manufacturer that has been producing foil components since 2013. This particular unit is sold as a cosmetic blemish (BLEM) — it was damaged during shipping and has never been used, but will require repair before riding. It is listed at a significant discount from the standard retail price of $329.00. The Longfuse 770 is part of Delta's M-Frame modular system, where all wings, masts, and fuselages within the M-Frame lineup are interchangeable.

Delta constructs its fuselages using prepreg carbon fiber with a high-density foam core, following the same build process used across their wing and stabilizer lineup. The 770 features a larger cross-sectional area than Delta's shorter fuselage options, which helps it handle the increased torque loads that high-aspect-ratio front wings generate during riding.

Delta recommends the 770 fuselage specifically for wing foiling, where the additional length over their Standard Fuse 610 provides greater pitch stability and makes foot switches considerably easier. The longer platform gives riders more fore-and-aft balance during transitions, which matters most during the learning-to-intermediate phase of wing foiling when consistent stance changes are still developing.

The 770 is also suited to foil surfing with high-aspect-ratio front wings. Riders pairing large-span, narrow-chord wings with their setup will benefit from the fuselage's reinforced cross-section, which is designed to resist the torsional forces those wings produce. Because this unit is a blemished item requiring repair, it is best suited to hands-on riders comfortable with carbon fiber repair or willing to have a local shop address the cosmetic damage before hitting the water.

Within Delta's M-Frame fuselage range, the Longfuse 770 sits as the longest option alongside the Standard Fuse 610 (610 mm, $299.00) and the shorter R-Frame 367 Medium Fuse ($279.00), which uses Delta's separate R-Frame mounting standard. The 770 and 610 are fully cross-compatible with any M-Frame wing, mast, and top plate, so riders can swap between the two lengths depending on discipline or conditions without changing the rest of their setup.

As a BLEM unit at $149.99, this listing represents an opportunity to pick up a carbon fuselage at well below its standard price point, though buyers should factor in repair costs. For those shopping at full retail, the non-blemished Longfuse 770 carries a $329.00 price tag directly from Delta — though it is frequently out of stock.
