So my dad and I bought a boat 2 : 1981 striper 17' restoration

Postby BWbert » Wed Apr 25, 2018 10:25 am

Hi everybody. I'm back! with a new restoration.

Our current project, a 1981 17' striper was bought a couple of months ago from one of our clients.
She is planning on buying a bigger boat for her resort, and she wanted us to be the first ones to consider buying the boat.
Well..., we did and we're excited to share the restoration with you all.

Sit back, enjoy the ride, and welcome to 'So my dad and I bought a boat 2'

The day the boat came, we could already tell it was in a bit of a rough shape.

We stripped the railings and fixed the engine up as well.
All the e-tec needed was a new fuel pump and it fired right up.

The whole point to restoring this boat has been to come up with something unique.
Our clients loved our first restoration, so we wanted to use that as a base.

I started doing some google searching, till I came about the 40th anniversary whaler 13
My dad and I both love that model so we thought, heck let's make its bigger sister.

We called our favorite glass mechanic, and he started immediately.

We've been going at it like clockwork. Our progress has been twice as fast compared to our previous restoration. The boat's interior has been painted and we're planning on tackling the floor today. There is one minor soft spot upfront and the old old foam should be scooped out today.

We've finally come to the part where my helpers and I dig out and replace the old foam. We started out checking how far the soft spot of fiberglass was spread, cut this out using a grinder, and we started digging out the old wet foam.

Thankfully the general area of soft fiberglass wasn't all that big and we ended up cutting a trapezoidal piece of about 10-inches wide at the top, 21-inches wide at the bottom, and 15.5-inches in length from top to bottom.

To make sure we did not miss any wet foam or rotten wood, we kept digging until we spotted dry foam and wood, and we then cut out an extra 2-inches of wood on each side.

For the foam to expand and stay inside its compartment, we cut two 10-inch pieces of marine plywood and held them down with stainless steel screws. These would help us later, screwing in a new floor piece (lid) to keep to foam inside.

The following shows us filling the compartment with foam.

We used 2-lbs two-part polyurethane foam from SeaHawk. We used [less than] than a cup of our half-and-half mixture.

It took about two minutes for the foam to expand and dry. We closed off everything with 1.5-ounce chop-mat fiberglass soaked in a polyester resin mixture.

BERT--after you made a trapezoidal cut-out into the original deck, removed wet foam, introduced new foam, and used a piece of plywood to contain the foam as it expanded, did you leave the plywood in place to become the underlayment for the deck?

Are you going to re-use the cut-out section of the original deck atop the plywood?

BERT--when you removed foam from the interior of the hull in the area under the trapezoidal deck cut out, did you establish a nice, clean, straight-line edge for the boundary of the old foam to the new foam?

We did leave the cut-out as underlayment for the deck.
We did our best for the new foam to allign with the old foam.

BERT--you also mention removing some wood from the hull interior. Can you describe in more detail where the wood was located? Was it part of the deck underlayment to reinforce the deck?

Yes [the removed wood] was the deck underlayment. Where we cut open and dug out the foam, we also removed and replaced the wood.

BERT--thanks for the further details. I know it is hard to accomplish work and take pictures at the same time, particularly when the work involves getting your hands dirty. You are doing a nice job of documenting this work.

No problem. I'll do anything to make it better :)

Before I continue telling the story of our progress,
The same day we repaired our boat's floor, we also applied our anti slip.
We primarily decided on the interlux anti slip of which pictures of its result will follow.
Not that its a bad brand, but the result did not give an aggressive enough grip.

How the anti slip was applied was by mixing it together with paint, and rolling the mixed batch unto its desired locations.
We could have used more but that would be a waste of a rather expensive product.

After further conversations with some of my boatbuilder friends,
they explained to me that interlux is used more after applying aggressive anti slip.
It's a way to make the anti slip's texture spread out evenly across where it is applied.

We've had a bit of a rough week due to sudden heavy rains.
The paint that was already applied did hold, but we decided to wait out the bad weather and choose a date to re-apply paint.

While this was going on, we did find time to apply the new anti-fouling.
What we used was Total Boat's copper-free anti-fouling that is said to be more resilient against drag.
We have had good experience with the paint on our own boat, even gaining a minimum of 3mph,
and since our 17 striper already had anti-fouling, we found it would fit to apply a fresh coat of bottom paint.

Weather finally cleared up. We lightly sanded down the original coat of paint using a light grid sanding sponge.

Final coat of paint has been applied and we're satisfied to say the least.
We're letting everything dry up right now for us to inspect it later.
After this we'll re-apply a thicker anti-slip, and afterwards we'll continue with interior detailing like the console and casting deck.
