KDI Pricing

The ‪#‎KDI‬ kit pricing is in. The 15-sheet, CNC-cut kit ready for shipment to you will be $3,165.70. That is the entire boat's worth of plywood CNC cut and the plans set which includes 28- 11x17 sheets in a nice binder, a full manual, and a sheet of full size patterns. The boat will also be available built from plans. The plans set alone (with manual) is on sale for $225.00. Price is good for the rest of 2015.

November at the Studio

Progress on mkII Deer Isle Koster

The new KDI kit in CAD file view
Files and plans are in the last week or two of development for the KDI, mkII. I am taking orders for kits and plans. There are four excited builders waiting for them to arrive. Won't you join them!?

Many want to know the changes from MkI. Mainly, the boat has been brought back up to the original 5'10" beam that Bruce drew on the original KDI's. Another change is that the nearly flat garboards and solid wood keel have been replaced by a piece of 3/8" plywood and the first two planks. The joints are glassed and the bottom sheathed (see hatch markes in picture below). This will make building simpler and alow the builder to make a very durable bottom for beaching. The mk II wll be roomier inside and I expect it to have faster off-wind speeds. The specs for the new KDI are below.

LOA 14'
BEAM 5'10"
LWL  12'5"
Beam WL 51 1/4"
draft 5"
Displace. 595 lbs
Sail area 97 SF

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 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

Design Projects

Sponsorship and Commission Opportunities


A new approach to getting projects funded and delivered is through a model sort of like crowdfunding. A design project is any boat design that is either started from scratch or a project where an existing design (that has been built) is reworked or it may be a boat that has been design but not built which needs further development.

The KDI has been crowdfunded for this Fall...a number of sponsors pay into the project and receive the plans for free and a discounted kit. I benefit from having paying work, We all benefit by having the work get done! 

The hull lines for the new KDI sketched out.

Another design project is the Drake Raceboat. It has never been built, but needs sponsorship or a commission to finish the speculative work that I have started...a 3D hull model. Further work to do is to build a hull model,  finish designing the interior, create cutting files and draft the plans. The Drake Race is all about speed and efficiency but retains the seaworthy faering-esque hull.

The Drake Raceboat has been modeled in the computer but that is it until sponsorship comes along.

Another design project is the Caravelle Skiff. It has been built a few times now, but soon a sailing model will be launched and from those sea trials a set of revisions will me made (I will call it a mk2 model) and the plans and kits will be delivered to those who preorder kits. I am looking for a few more preorders. A gent in NYC will cartop his skiff to all sorts of places around LI Sound for sailing and rowing.

Lastly, an example of a scratch design project is my brief detailing what I will likely call the Calendar Daysailer, which is actually the precursor for the sail-and-oar boat the Calendar Islands Yawl. This new boat model will be 90% daysailer with water ballast and a motor well and a lot of space for 4 people to go out sailing.

Developing the Calendar Islands Yawl Daysailer

Be part of the Calendar Islands Yawl project this winter

Calendar Islands Yawl daysailer

New design

the brief:

      Hull above will be modified to create more of a daysailer hull form with ample freeboard and some deadrise for choppy water. Narrow flat bottom will be retained for beaching.
·         Capacity will be up to 4 people maybe 5
·         Loa ~18’8” x ~6’6’
·         Weight estimate ~200lbs
·         Plywood stitch and glue bottom and lapstrake topsides 9mm ply
·         Large foredeck with coaming and high bow make it a dry boat
·         Lug-awl rig or gunter-sloop configurations w/ centerboard
·         Auxiliary power by oars or small OB motor
·         Interior layout with side benching and a thwart across to stabilize cb trunk and provide a spot to row from
·         Motor well aft, 2.5-4hp
·         Side benches aft and forward compartment provide positive flotation

      The idea is to find an interested group of people to help fund this work. If you are interested in having a fantastic daysailer that you can have an influence in the design, please email me at

Early Summer 2015

Early Summer Activities and Updates

Prep, prep, prep!

Mostly my work focuses on watching four Deblois Street Dories getting finished, one of which has hit the water. Compass Project's Dory launched successfully with a a bunch of excited students who helped build her. Compass is looking for another big project commission to use in their work with at-risk youth.

2015 Compass Project launch of the DSD.

I am busily preparing the cutting of more Echo Bay Dory Skiff kits which will be built in Maine. This is the very latest version of the Skiff and any tweaks in the design demand a lot of attention to make sure all the details get done correctly. Those files are done and ready for more customers. It is hard to believe over 30 Echo Bay's have been built now!

Also in the works are the files for cutting the first ever St Lawrence River Skiff kit for the Bain & Co. Annie model. I am back in the computer model after quarter scale modeling the hull.

Quarter Scale Model of the St. Lawrence River Skiff, Annie to be built at ABM in an August 10th workshop.

Here is the information for my workshop in August. Spread the word! Contact me for more info.

NEW! St. Lawrence River Skiff Building
Clint Chase, an instructor at the WoodenBoat School, The Landing School, and The Compass Project, will teach how to build a St. Lawrence River Skiff. This boat is plywood and strip-composite constructed. One kit will be built in the class and raffled off to one student on Saturday. The boat will have some finish work to still be completed by the raffle winner.  Participants must register by July 27 to make sure the class will run.  For more information about the boat visit:
Instructor: Clint Chase
Session 1: August 10– 15, 9 AM- 5 PM
Tuition: $1000
