I'm assuming that you have a Scuffie 16
, a fine looking boat
I built a plywood
21'6" centreboarder a while ago.
I had a look at the article you linked to and what he's written is good.
The following is my opinion and must be checked by contacting the designer
or their agent.
Assuming that you have sanded back the original paint
to pretty close to bare wood
* Plywood is particularly susceptible to delaminating and rot
gets into it's edge. If your boat was not built using the WEST system
or similar then a major repaint is a good time to address this.
My personal feeling is that one of the rotproofing saturating epoxys needs to be brushed into every edge and cranny, using multiple applications until you are quite certain that no bare wood
will ever be exposed to water
I'd suggest following that up with an epoxy
putty so that all is smooth.
* Others may have different opinions but for mine unless weight is an issue I'd go for a layer of epoxy
fibreglass over the cabintop, deck
. Heavier fibreglass cloth could give a rougher finish on the deck
and cabintop, while lighter cloth that will give a smooth finsh when painted may suit the hull. You may need to remove the ballast and centreboard to do this, and it is a big job, but doing it could considerably extend the lifespan of your boat.
* The interior
will also need attention unless it is in excellent condition. Again multiple coats of penetrating epoxy (please pay particular attention to all safety
instructions when working with solvents in a confined space) and I'd suggest going with one or more good coats of unthinned epoxy resin anywhere that water could pool. Topcoating to protect the epoxy from sunlight is necessary here. If the woodwork is already clear finished a UV protected varnish
would look nice.
* Some hardware
store paints are of excellent quality, but it is hard to know this from the label or customer service
paints of a reputable brand are not much more expensive than quality household paint and come with an assurance of quality and consistency.
My opinion again is that two pack polyurethanes are not necessary for a good finish and that single
packs are much easier and safer.
