KDI Design Project

KDI Update

Hull & Deck Built


KDI Mk2: Looks the same for the most part from this perspective. 
You can see different color planks. That foot wide strip will be stitch-and-glue style so that it can be fiberglassed.
Narrow entry makes her fast.
She is just over 5'10" wide not including the rubrails.

Happy September!

Late Summer Update and Announcement

The KDI project is fully funded thanks to a group of enthusiastic sponsors. Thank you! I now have a lot of work to do through October!

Drake Raceboat in perspective (more screenshots below)
In November and December I hope to have funding to further develop the Drake Raceboat. A campaign to get this crowdfunded begins. Three sponsors at $600 each (or six at $300) will get the project funded and you will get a full suite of plans, and preferred status for first kit cutting with a 10% discount. Please contact me at boatkits@gmail.com if interested. The final design brief for the DRB is as follows:

  • A fast rowboat in the Drake spirit optimized for single, fixed- or sliding-seat rowing
  • Ideal for fitness rowing and the open water racing curcuit 
  • 18'3" LOA (kit) stretchable up to 20' by spacing out molds (plans)
  • Waterline length almost 17', 27 1/2" waterline beam
  • Max beam is set at 4' so boat can be rowed in fixed seat class with 8 1/2' oars
  • Sliding seat is an equal option in this boat, the Poseidon rig being the ideal, using sculling length oars
  • Oarlocks for sliding seat can be mounted using Shaw and Tenney oarlock brackets or a custom made outrigger that fastens to gunwales (TBD)
  • 5 kts speed potential race pace with 6kts in sprints
  • Flotation tanks optional in sides or ends, but more likely flotation bags will be used and canvas decks to shed water
  • Glued lapstrake construction, 4 strakes per side (4mm), no fiberglass 
  • Estimated weight below 75 lbs at kit length
  • Numbers from computer model"
Cp = 0.58
Volume Displacement = 306 lbs
Center of Buoyancy = 53.9% aft
Wetted Surface Area = 27.74 sf
Waterline Length = 16' 11 1/2"
Maximum Waterline Beam = 27.6781"
Water Plane Area = 24.5 sf
Center of Floatation = 53% aft
MSA 70.1711896 (+/- 1e-08) square inches
