This is a 1969 Dolphin 13'. Dolphins are a Sunfish clone. Lateen sail dinghy. Finally had a free weekend so decided to rebuild the trailer.
The hardest part was disking off the rust. You can see how rusty it was in the original pic. Other than that pretty fun, and should last another 40 years. Supplies: New lights/wiring $20 Carpet $10 Wood $8 (odds/ends pile at the back of Home depot) Rust remover disk for drill $6 Paint and clear (3 cans of black Rustoleum, and two cans of clear) $15
