Hello From Saskatchewan

I was on the fence about redoing and modifying my boat but gravel roads and a very rough boat launch have made my decision for me. I have a short drive to the lake but its definitely not paved. Thus my probable soft transom is failing. It doesn't help I don't have a leg support. I will have one after the rebuild

I bought the boat this spring (my first boat) for a decent price knowing what I was I buying. The old Merc 800 is strong and runs very well. I have honestly used the boat more this season than the previous owners did in 6 or 8 seasons. I went fishing and took the family out every weekend sometimes going out twice a day.

The cracks in the fiberglass on the transom have been getting bigger and producing evil little offspring so... today was my last fishing day for the season


My plan, such as plans go, is to tear down and grind this fall and rebuild in the spring when things warm up while the ice melts off the lake.

This afternoon I tore out all the crazy bubba wiring, carpet, controls seats, etc. The motor bolt nuts are off and all that's left is to take the hydraulic lines off the trim pump to pull the motor

I plan on building a jig on the trailer to hold the hull in place so I can pull the cap off and cut out the floor next weekend
The trailer is great for this because the previous owner did a decent job of sheeting it with plywood to protect against gravel roads


As you can see in the pic I have a large ( unheated ) Quonset where I can lift off the top and store it. I will drag the hull out and grind outside. I don't have much for neighbors and if the coyotes have issue with dust they can howl at someone who cares lol.

The floor is of course soft in the back and I foresee much wet foam and various nastiness

Now for the modifications and the dreams, or nightmares depending on ones state of mind at the moment. I would love to hear from everyone as to why I cant do what I want to do and why there are issues so they can be worked through and planned out. At least up until and a little before the epic internet fllame war with subsequent timeouts and what not

As such I will provide some personal background. I have zero experience with boats and just enough with fiberglass to know how frustrating it can be at the worst times. I have had some success but more of luck and boldness than thought and finesse. I was a carpenter for too many years but have switched mediums and now work in metal fabrication. I worked for a year and a half as an industrial painter and still have access to the massive paint both, which will obviously come in handy.
Thus I have an idea of structure and how things are generally built.

I want to turn this boat, seeing as I have to redo it or landfill it now, into a fishing boat with a front fishing area, livewell , rod storage storage compartments bla bla. I had thought of a bow mounted minn kota V2 come spring but my already lousy fish finder gave up the ghost and carped the bed a few weekends ago. So new electronics trump the motor but a proper mounting location must be built for the future

I want to cut out the existing bow deck around the blue area and drop it down to the level of the step as a fishing deck.





I believe this will give me ample room for underdeck storage for trolling motor / electronics batteries and the required structural bulkhead where the current one resides. I would like to install the obligatory seat post in the front as well.

I hope to be able to add a center rod locker.

In the rear I want to cut out at least half of the splashwell and kooky deck design


This will allow useful storage to be buit on the sides. I will drop the deck further forward to allow for my fuel tanks and build a stainless steel livewell that will serve as the back wall of the splashwell and rear bulkhead to retain structural strength


Seating will become 4 mpveable post type folders with extra center

In case you're wondering, the road dust settles a tan color and gets everywhere so all future interior seats, vinyl, carpet (gasp) will be close to road dust tan, giving the illusion of cleanliness

Welcome to iBoats! Sounds like you have a plan. Once you have the cap off and the hull gutted, you'll have a clean slate and you can pretty much build her back to suit your needs. Just make sure the transom and stringers are all installed to spec and then you can build her to suit. There are several examples of closed bow boats having been converted to fishing platforms. Do some searching and you'll see what they did.;)

Thank you for the welcome

I searched once or twice but obviously not very well. I'll try again, I would very much enjoy seeing what others have done

Really like the look of your boat, very unique. Also what kind of mount is that for your FishFinder?

The mount is from a surius satellite unit. The original mount is the Grey thing mounted sideways next to it. The original mount was completely useless

Worked on the boat today.
I pulled the motor off bubba style with a crane strap, cheap nylon rope, an old cloths line pulley and some random pulley of unknown origin I found somewhere because I sure as hell wouldn't have paid for it.
No pictures, as it was a don't try this at home type thing.
I lost a lot of hydraulic fluid out of the trim system, so I'm looking forward to hearing bleeding the system is next to impossible and I should have been extremely carefull to plug the lines and not let the fluid out because I wasn't

Now we start to unravel design flaws. The drain for the splashwell is higher than the bottom of well. Thus is holds water against the crappy plastic grommet which is obviously not water resistant



One can clearly see the transom is now curved while the angle bracket at the top rear is still straight. Gonna be very swampy in there, might need to have the 22mag ready for gators when I venture in.

next up I built my bracing off the trailer. I used some strips of backer board to create a template of the bottom
I wanted to use my hot glue gun to stick them together but I have a teenage daughter... so.... who knows where it ended up

I had to use screws which is more of a PITA but I didn't need to be very accurate, Only close because I planned to put blocks in it after anyway

Typically I would use some small clamps, apply hot glue at a joint, clamp for 1 minute and good. Its a way of making fast templates




Once I had everything snug, but not under compression I added a step seeing as I will make more than one or two trips in and out of it .

/
I then pulled off the windshield and the rub rail. The plastic was very stiff, I assume I will replace it with new more supple plastic during reinstall?

Many of the stainless screw's heads stripped even though they were thankfully Robertson head (square ) I drilled the heads out of the stripped ones. For those who do not know, use very slow drill speed and more pressure when drilling stainless, use cutting fluid. High speed quickly ruins drill bits and creates unnecessary frustration . WD40 or similar will work as cutting fluid in a pinch

The cap is loose and ready to lift

Im going to leave the cap as is until my rebuild in the spring. My thinking is to leave as much material possible for the long storage, I might be easily convinced to put it back on for the winter after I finish the itchy part.
More demo on sunday

PLEASE offer advice or corrections to what I have done if you have

It rained all day today, I separated most of the cap but it's half hazardly tabbed to the transom in what can only be described as grotesque.

I'm not prepared to grind fiberglass inside my quonset , nor grind in the rain , so I'm relegated to interior house renovations
Uggg

Making the steps was a good idea ! I wish I had a nickle for every trip in and out of the the boat on my restorations ..

DANG IT!!!!!
All week I've been excited to work on my boat this Canadian Thanksgiving long weekend. I've had Friday to Monday off , Friday and Saturday were going to be working on the house with yesterday and today nothing but boat
Sigh...
Yesterday it rained all day. Today it's gusting to 80km/h (50 mp/h)
I dare not take it out of the quonset to grind the transom tabbing in order to pull the cap. The wind would snap it off before I started

Oh well, life on the prarries I guess :-(

I finally got a chance to work on my boat again. I pulled the cap off
This is what was between the transom and cap
I assume it's "PB" without out chop strand


The transom is bowed not because of rot, but because of delamination


I will replace the transom. as there is no good way to laminate the pieces or take the bow out. As well I will bend an 12ga aluminum U shaped plate to stiffen the top of the transom in place of the old flimsy 22ga aluminum angle piece.

Now to the floor. I had assumed it would be mush as it is so soft and the stringers rot in the stern. Turns out I am wrong. The floor is soft because it's made out of 7/16 cheap plywood. The tabbing on the stringers is shameful and equal to the worst fiberglass I had ever seen in my life, that's on the bow. LOL

WARNNG, viewer discretion is advised







Old world craftsmanship




So its a brutal job. BUT, there is no rot at ALL, NONE

The boat is from 1980 which puts it at 35 years old. While this may well be the most appalling fiberglass work this side of the 49th it has done what it needed to do for 35years. I reckon redoing the stringers and deck to be $500 in fiberglass and wood. That's $500 towards an Ipilot minnkota. Yes the plywood is undersized but again, its worked this long and now I have piece of mind its not rot.

Now lets view what I'm guessing is the mother of all air bubbles. If your pregnant or nursing please do not view the following picture as it WILL harm the fetus



That is the bow cap support , again no rot anywhere
Seems somehow unfair this boat being built so crappy is rot free while others with big ticket boats have been nightmares, luck of the draw is suppose because it sure ain't do to clean livin'

So this leaves me at a stand still until spring. I am attending steel fabricator school in JAN and FEB so I will be without income for all of January. Thus leaving my boat budget at exactly zero until March. I believe leaving the transom in place until I am ready to replace it and leaving everything else in tacked is the prudent course of action till all the supplies are on site.

I am going to place the cap back on until then with dreams of custom stainless levewells, front decks and storage compartments to keep me occupied until then.

If anyone has a comment, suggestion, idea or advice I would love to hear it

Hillbillyr,

Are you still working on your Vanguard Gemini?

I own one in Edmonton, AB and would like to hear more about your project.

Let me know,
