Overview of Making the Cockpit Coaming

Preparation

The hole pretty much defines the shape so cutting the hole accurately is step one. Since that step the boat has been fiberglassed and the rough edges left over from that need to be cleaned up.

Carbon/Kevlar, Carbon Fiber and Glass on the Petrel Interior

You don't need to see more sanding, but that is what needs to happen before glassing the inside so I kept the sanding footage to a minimum in this video. Next I added a fillet in the chine. The Petrel has a hard chine aft of the cockpit, while it doesn't need a fillet adding one will strengthen the corner and make it easier to lay in the fabric.

Putting an Accent Strip on a Stained Hull

Like the feature line on the deck, I wanted to have a bright maple accent along the sheer line between the deck and hull. Since the feature on the deck was in the middle of a stained area I had to stain the accent strip and then scrape the stain off.

Applying Fill Coats - Light and Heavy

I'm applying two different sort of fill coats in this video. One is quite light and the other is heavier. The hull will eventually get another layer of fiberglass, after I have joined the deck in place.

Fiberglassing the Petrel Deck and Hull

At the start of the day I went into the shop and turned the heat up to 80° F (27° C) and made sure the lamp I keep on my epoxy to keep it warm was turned on. This assures the epoxy flows easily.

I rolled the cloth out on the boat about an hour before I started glassing. I could have done it earlier, but I did want to give it some time to warm up to room temperature.

Staining Video

I posted a long article about staining about a week ago, and here is some video to accompany it.

Fairing and Sanding the Petrel

Here is where you start to see the beauty of the wood. The drips of glue get scraped off, the angles between strips get planed down and the wood gets sanded.

Staining your Kayak

Using stains to add a little extra color to your boat.

There is no accounting for taste, but for some reason I find okoume a little bit boring. While the grain can be quite nice, the color is often a little bland. In my opinion it would often benefit from a little pumping up.

Installing the Coaming Recess

I constructed the coaming recess in the last post, now the trick is to install it in the boat. I start by smoothing the deck a little by giving it a quick scraping. This just makes it a little easier to mark the hole.
