NOW AVAILABLE: Building Plans & Kits for Doug Hylan's OONAGH

Finally — A Rowing/Sailing Dinghy That's a Legitimate Alternative to the Inflatable RIB
(And a Capable Camp-Cruiser As Well)


PLANS SET - $149 plus shipping
Seven sheets: sail plan, lines plan, construction plan, building jig, full-size patterns, and plank layout. Shipping cost is $20 for U.S. addresses and $60 for international orders. The plans also come with a materials list, other recommendations such as qualified sailmakers, and access to about 30 photos of the details of the finished boat.

CNC-CUT KIT - $1,995 plus shipping (Introductory price for U.S. for limited time):
Kits of all the plywood pieces, pre-cut, can be ordered directly from Hewes & Co. in Blue Hill, Maine. To order: Email Gardner Pickering at [email protected]. Kits ship within 4 weeks and often quicker, on a first-come-first-served basis. Plans sets are not included with the kit and must be purchased separately (see above paragraph on "Plans Set").

International Purchases of the Kit: Kits from Hewes will be available in a variety of locations around the world. Hewes currently has a partner for deliveries in Europe, and they are currently working to line up a partner in Australia and New Zealand. Please inquire with Gardner to see if kits can be cut nearby you and delivered to your location and pricing, as price above is for U.S. deliveries only.

There is an additional fee of approximately 15% for international orders outside of the U.S., so please check with Gardner re: that specific amount for your location. Please note that the kit can ONLY be produced by Hewes' trusted partners and having digital files sent to another CNC shop near you is not an option.

Kits consist of CNC-cut plywood only; rails, seats, and other pieces of “real” wood are not included, nor are the spars, sails, or rigging.


Rather than settle for an inflatable RIB that can hardly be rowed and cannot be sailed, one of today's top small boat designers, Doug Hylan, has created OONAGH (pronounced "oo'-nah") as a legitimate alternative to the inflatable/RIB dinghy.

Exceptionally seaworthy, this design achieves the trifecta of rowing, towing and sailing—and doing all three remarkably well. She also motors along quite nicely with a small outboard motor. And she's steady as a church when stepping into her from the mothership. With oversized gunwale-guard wrapped around her rails, she cozies up nicely alongside without causing dings or rashes.

This boat can be built by anyone with reasonable woodworking skill using:

NOTE: You can build it from the plans alone, but the kit and video series make it much easier and save you a good deal of time.

The design's formal name — OONAGH — comes from a clever mythological giant who can hold her own in tough situations. But as A Real RIB Alternative, we at Off Center Harbor have already given this head-turning boat the nickname ARRIBA.

LWL – 9′
BEAM – 60”

MOTOR - Yes, Electric or gas up to 2hp is all she needs
SKILL LEVEL REQUIRED – Beginner with modest woodworking experience

From designer Doug Hylan: "I know that many people are going to want to put a motor on OONAGH, so she is designed for it. The tucked-up transom that makes for decent rowing will preclude planing, so there is no point in putting anything more than 2 horsepower back there. In fact, one horsepower is as much as she can really use effectively. This begs the question – why not electric? Why not indeed! A small electric motor will push her along nicely, and you will be able to carry on a private conversation while enjoying the scenery."

DOUG HYLAN: "Beyond use as a tender, OONAGH will make a fine boat for family sailing, fishing trips or just an evening row with the kids. Her simple construction and detailed plans will make for a good family construction project as well. I can guarantee that the experience of building, then using, a small boat will be a treasure that your kids and/or grandkids will carry with them throughout life."

An 18-part video series that shows how this boat comes together will be available to all Off Center Harbor members. OCH members also have access to two other epoxy/plywood boatbuilding series, plus two more series on how to use epoxy, totaling about 80 OCH-produced videos. The OONAGH series was filmed at Hylan & Brown boat shop, with Kit Macchi, one of their skilled crew doing the actual building. Episodes of the video series will be released this fall and winter (2020-2021).
