Expanding on a successful concept

The Didi 38 has become one of our most successful designs, now being built the world over. The radius chine plywood design was an experiment that has grown into an expanding range of performance concepts primarily for amateur builders.

The Didi 38 was offered from the start with extended stern and longer cockpit, aimed mainly at improved racing efficiency. A demand has developed for this extended hull to be combined with a short cockpit and longer cabin, for improved cruising comfort. We now offer this alternative.

This version is based on the Didi 38, so much of that boat remains in the character of this one. The differences are:

  • Heads moved aft, where most ladies prefer it to be
  • Forecabin gains space due to relocation of heads
  • One large aft cabin instead of two smaller ones
  • Large lazarette for storing bulky items away from interior
  • Option of U-shape dinette with fuel tank under aft dinette seat or under cockpit

As a cruiser, we suggest that she be built with 18mm skin rather than the 12mm standard for the Didi 38. This will give her more resilience for long life and safer cruising.

When buying the plan package for this design, you will receive the full set of Didi 38 drawings plus the additional Didi 40cr drawings that cover the variations for the Didi 40cr. The full set includes all rig and keel options that are available for the 38/40, so you are able to combine features to produce the character of boat that you want.
