Building the St. Lawrence River Skiff from M.A.C.K. Products

Had the oppertunity to review the M.A.C.K. Products St. Lawrence River Skiff, so thought I'd post it up here as well.

The kit is excellant, primarily of bass wood construction. Plans and Instructions are good, and the laser cutting is first class. Overall, this is a really nice kit. So, lets get started.

Setting Up the Hull Framing Jig

The hull is cold molded over the laser cut framing jig supplied with the kit. The jig is assembled and tack glued to the building board, and is where the hull planks will be shaped and glued in place in the keel assembly.

The keel assembly is then built up and tacked to the jig. From there, the planks are glued in place one at a time, starting at the keel.

Fitting the Planks

The laser cut planks are fitted one at a time, working from side to side to keep the loads symmetrical until all the planks are in place. There are 7 planks per side.

Generally speaking, the planks fit really well. There was a bit off pulling and tugging involved, but none needed trimming to fit. Then once the planks were in place, the hull was removed from the jig and the final gluing done to join the planks down the length of the hull. The stem and stearn caps were added and the hull sanded to final shape. A coat of thinned West Systems epoxy brushed on to seal the wood.

Adding the Hull Ribs

Once cured, the jig formers were taped back into the hull to hold its shape while the ribs are fitted and glued in place. Spacers are used to mark the location of each rib.

Gluing the Ribs in Place

The ribs are added one at a time working toward both ends from center center. As the process progresses, the next former in line was removed untill all the frames had been removed.

Finishing Up the Ribs

After all the frames were removed the ribs were added all the way out to both ends.

To aid in forming the wetted bass wood strips for the ribs a piece of 1" dowel was used to form the basic shape, then once glued in the ends were trimmed with a fingernail clipper. Once it was all finished and sanded, 2 coats of spar varnish were brushed on the inside of the hull.

Fitting the Floorboards

With all the ribs in place, the hull was now completely rigid, and much easier to work with then before when it had a real mushy feel about it. The laser cut floor boards were fitted and glued in place. Again, the fit was near perfect, with no trimming required. Then once the floor boards were in, the speaders were added at both ends and the deck added.

Fitting the Deck

The deck was glued in place next. The parts are cut a bit oversize, so there's plenty of room for alignment. Once the parts are aligned and glued in place the edges were trimmed and sanded into the edge of the top plank.

Adding the Cockpit Combing

The cockpit combing was added next. The front and rear sections were wetted and preformed around the wood dowl, then glued in place. The mid sections were then added.

Then the rub rails were fitted and glued in place, sealed with thin Cya, and the belt line between the rails was painted blck. Planned to leave the planks natural, so wanted a little color for contrast.

Fitting the Seats

The seats were trimmed to fit, then the seperation lines scribed into the boards with a home made tool. The wood was then stained and two coats of varnish applied.

Woodybob, Oh no, been working on this one for several weeks. It's a great kit, but is also a challenging build.

Building the Oar Locks

The oar lock pins were fitted into a cutting jig and cut to length, then removed from the jig and glued into the laser cut plywood brackets.
