Gulf Star 36MK "Reef Monkey" Project

I've always had a thing for the old Gulf Star trawlers. Several months ago I found Reef Monkey, a 1975 Gulf Star 36 MKII for sale on craigslist and adopted her. She has twin Perkins 4-154 and a 12kw Northern Lights Genny. Mechanically, she is an alright condition. Cosmetically, she needs some love.

The teak toe rail and trim has been painted brown with house paint. The gel coat has a lot of crazing and stress cracks. There are quite a few leaks that need to be addressed. The deck is severely blistered in places due to Treadmaster non-skid mat holding moisture. Both air conditioning units don't work. The aft deck has a pretty severe soft spot. The swim platform is deteriorating. And at one point in her life she had a "professional" paint job that appears as if the paint was applied with a mop.

My goal is to do a practical restoration of the boat. Anywhere that I can avoid complication or reduce maintenance will get attention. I have always enjoyed reading project threads, so I I plan on posting updates in this thread as the project processes!

Those old Gulfstars are great boats (in my opinion). Good luck with the project, and hoping to see those updates from time to time.

Since my daughter is living aboard for a while before heading off to college, I spruced up the interior a bit and replaced both old non-functioning split AC units with one 16,000BTU and one 12,000BTU Ocean Breeze stand alone units. Air conditioning is not optional down here! I didn't think to take pictures of the process, but I basically tore out the old air handlers and compressors and bolted in the stand alone units. New wiring, new plumbing, and new ducting.

Now that the interior is "inhabitable" its time to move on to the exterior! I will re-visit the interior once 100% of the leaks have been fixed and all deck fasteners have been re-bedded.

The aft deck has had a pretty bad soft spot. It seemed softest on the starboard side of the hatch. It is time to open things up and see just how bad things are. I have been told that soft spots are always bigger than they seem once you open things up. That is the absolute truth. There was so much moisture water was literally puddling in an area!!! Unbelievable.

So, I ended up removing about a third of the deck skin and core. Keep going until there is nothing but good clean balsa core. I won't be replacing the skin, so although a bit annoying, the odd shape of the removed area isn't a big deal.

These older Gulfstar 36 and 43's are ripe for refitting IMO. Priced right with pretty reliable old Perkins diesels. Look forward to following your project.

For some reason, Gulf Star cored the deck strange. Fiberglass boat building was a new concept at the time and they were figuring things out as they went. Reef Monkey had only one layer of glass mat under the balsa core, but about 5 layers on the top skin! Also, there are no stringers or any structure to keep the deck rigid. This results in a slightly "springy" aft deck.

The original layup was like this:
[Glass Mat]
[Glass Mat]
[Glass Mat]
[Glass Mat]
[Glass Mat]
{=======}
{==Balsa==}
{==Core==}
{=======}
{=======}
[Glass Mat]

I added 2 additional layers of glass mat on the bottom layer below the core. This will increase rigidity a bit.

The new layup is like this:
[Glass Mat]
[Glass Mat]
[Glass Mat]
{=======}
{==Balsa==}
{==Core==}
{=======}
{=======}
[Glass Mat]
[Glass Mat]
[Glass Mat]

I replaced the rotted out balsa core with Divinycell closed cell foam core. It is a good product, easy to cut, and will last an eternity.

Wetted out 3 layers of biaxial glass mat over the core and we have a deck we can walk on again!

First off, it is good to have a buddy to help out with this kind of work. A second set of hands makes things go faster and another point of view helps out tremendously. I don't recommend tackling a big job like this solo.

If you have Treadmaster non-skid, chances are your entire deck is blistered and toast. Apparently moisture is retained between the gel-coat and non-skid mat. Over time that moisture absorbs into the polyester resin and forms a blister. Anywhere there was Treadmaster non-skid there is severely blistered fiberglass under what is left of the gelcoat. I wish I took better pics of the blistering.

Each blister was opened up and aired out. All the gelcoat on the deck had to be removed. A dusty/itchy/dirty job.

Some of you guys are going to freak out, but I'm removing the teak from Reef Monkey. Don't get me wrong. Teak is beautiful. I love teak... on other peoples boats!

The previous owner painted the teak with brown house paint. Ugh... What an eyesore. Plus, the crazing/cracking in the gelcoat extend under the teak toerail. So... bye bye teak!

After removing the toe rail I dremeled out the gel coat cracks and filled with epoxy fairing.

Love the progress pictures, great work

Tell your neighbor with the Gibson 36 houseboat that I love his color scheme.

Our boats have all had teak, varnished teak...
It is quite beautiful to look at and it is not all that difficult to keep up here in the North East but I am sooooo looking forward to no more teak!
We will find a nicely varnished boat to anchor next (easy when we are in Maine!) and enjoy that teak from a distance!!!
What a treat it is to watch someone restore their boat. I've been there before but I also enjoy the view from the armchair.
Many thanks for the opportunity.

Now its time to make it flat! Since I'm painting the boat I'm switching from polyester to epoxy resin. Epoxy is so much nicer to work with. It took 5 fairing passes to make the deck nice and flat. Sanding was done by hand with an 18 inch longboard.

The deck hatch trim ring is now fiberglassed in and encapsulated with epoxy, so there is no chance of leaking.

When somebody installed the hard top they simply cut the bolts to the corner cleats and left the holes gaping wide open with no sealant under the hardtop pipe mount! This was another huge water leak that is now fixed.

All the deck fairing is completed and a few coats of primer have been applied. Its funny how they call this type of work "painting a boat". 99% of the work is sanding, repairs, and prep. Not paint! It sure looks good to see everything white again.

Rolled and tipped 5 coats of Alexseal topcoat. It should have been 3 coats, but it has been so humid the past few days dew set in and ruined the finish overnight. I could have used accellerator, but it effects flow when brushing so I don't like to use it.

I prefer Alexseal over Awlgrip because it is just as durable, it can also be either sprayed or brushed, and most importantly it can be wet sanded buffed/polished for repairs. Alexseal was created by the same guy that formulated Awlgrip way back in 1973. Both Alexseal and Awlgrip are great 2-part polyurethane products, but the ability to easily repair (and remove any imperfections during application) is a game changer.

I'm going with Cream color for everything above the rub rail to keep the old school classic spirit of the boat. I've done a bit of painting in the past and was able to achieve a spray quality finish with no orange peel or signs of brushing. The transition between this area and the next painted area will be wet sanded and polished to remove the masking line.

No non-skid of any kind on the deck?

My reaction when I got into welding. They call it "welding," but at least 90% of your time is spent cutting and shaping the metal, and then cleaning up after the actual welding is done!

While certainly necessary, it is a shame that much of the beautiful paint job will be hidden under nonskid. At least we were able to appreciate it before you covered it up.

Thanks man! The rest of the boat will have just as good of a finish, so there will be plenty of other areas to appreciate.
