Grumman 17 SCOUT 18 Apr 20 Morning Coffee and Fiberglass

18 Apr 20:

SCOUT took us out for morning coffee and oranges, saw a few pelicans. Light winds from NE, tide coming in, river flowing out, 72F.


Skipper's duct tape cup holder works great.


Stanley thermos just for fun...


...just like the NC-4 crew used!


Beach Inspector.


Inner layer of rudder adapter is cured.


Wetting out the outer layers of 4 oz fiberglass cloth tape for the rudder adapter with TotalBoat THIXO. Worked the THIXO into the weave with part of a paint stir stick.


Stainless Ronstan gudgeons encased in fiberglass cloth. Rudder and pintle attached to get the correct alignment with the gudgeons.


Gudgeon shimmed with small pieces of wood where stern cap tapers.

Grumman 17 Canoe SCOUT 17 Apr 20 Fiberglass Rudder Adapter Gudgeons

17 Apr 20:

Borrowed Skipper's garden cart to make a tailwheel for SCOUT.



Carriage House visit for SCOUT to get fit with a rudder adapter.


Rudder adapter will be this size, with an upper and lower gudgeon. Built up from fiberglass and store bought Ronstan gudgeons.


We'll use 2 of these Ronstan gugeons and embed them in a custom made fiberglass adapter.


Ordered from Vela Sailing, 1/4 inch diameter holes for pintle.


Gudgeons will be fit to the stern cap and embedded in 4 oz fiberglass cloth tape, with TotalBoat THIXO thickened epoxy.


The 4 oz fiberglass cloth will be bedded in THIXO, pre thickened epoxy that comes in a 2 part cartridge. Use a High Thrust 18:1 caulk gun to dispense, not the standard household caulk gun, your hands will thank you.




6 strips of fiberglass cloth wet out with THIXO, they will form the inner adapter. Gudgeons will be added and an outer matrix of epoxy and cloth will form the outer adapter. We worked the THIXO into the cloth with part of a paint stir stick.


Taped poly film to the stern cap, then laid fiberglass strips, then another layer of poly to smooth things out.

Grumman 17 Canoe SCOUT 12 Apr 20 Rudder Adapter

12 Apr 20:

We printed up a real size photo of the rudder adapter for a Grumman canoe, then marked some measurements. The adapter is made from T-6 aluminum, with 2 gudgeons that take the 1/4 inch diameter pintle on the rudder. The adapter had a thin rubber pad underneath and attaches to the stern with a bolt through the stern cap bolt hole.



We used our pocket bevel to get the angle off of the stern cap, then marked that onto the pattern.


If anyone is geared up to make a piece like this, drop us a comment. Otherwise we might try making it from fiberglass and two Ronstan gudgeons.

Grumman Boats 07 Apr 20

07 Apr 20:

Worked on an article for Small Boats Magazine on the venerable Grumman 17 Double End canoe, so we pulled out the 1965 brochure to use as a reference. Also wanted to look at the sail rig photos to get ideas for our 17 SCOUT.



75th Year of Grumman canoes, still being made in Marathon, N.Y. by Marathon Boat Group.
