Looking for bottom paint in Canada

Looking for bottom paint in Canada

As the title says Im looking for paint for the bottom side of the boat I am building (glen L Zip)

It's going to be for fresh water, occasional usage and spend most of its time on a trailer, maybe 1-2 days on the water at a time if a vacation permits

I have coated the hull with fiberglass and west systems 105/207 epoxy

I plan on painting from the water line down and I'm looking for a darker blue to match my dad's sail boat he used System Three WR-LPU, polyurethane topcoat marine, in Lopez Blue. I don't believe this would be correct for my use?

I was told the interlux bottomkote ca was not for sale in Canada currently for some unnamed issue, it's not the blue I wanted but I'm tired of google giving me sponsored results and not being able to get straight answers

Any advice or recommendations would be amazing.

SAUNA on BOARD 🛥️ 🧖‍♀️ Has anyone built or rented a sauna on a boat? Looking for recommendations & real-talk advice

Hey everyone,
We’ve been seeing floating saunas pop up all over the place lately and we did already an Event for L’Oréal with a Sauna on the Sundeck and now clients are completely obsessed with the Wellness idea. Mixing a proper wood-fired hot session with an immediate water cold plunge straight off the deck seems like the ultimate setup.

I wanted to ask the community a few questions:

? For those who have used one: Is it as good as it looks online, or is it mostly just a gimmick for social media?

? For anyone who owns or built one: What are the biggest hidden headaches? Beside marine insurance and open fire on Board.

Layout preference: Do you prefer stationary floating sauna docks, or actual motorized sauna boats where you can cruise out to a quiet spot first?

Would love to hear your experiences, favorite spots, or any build advice!

How hard will this be to repair.

Hi there. I’m looking to buy this portable for $150 on marketplace but the transom looks like it need repair. Would I be an easy fix? I’m good with cars and have a bunch of tools but I don’t know anything about boats. Would you ever buy this?

Yamaha 130 V4 alarm issue

So I have a issue with the alarm being on when I put the key in the on position I checked thermostats compression float switch and I just can’t seem to figure out why the alarm is still on. It is in limp mode. Any help would be very much appreciated. Only thing I can think of is is a bad harness or relay somewhere.

Upgrade my Flat Bottom Punt Tinny

What does everybody think any advice, it’s 4.4 meters long so I didn’t really think putting the speakers inside the bench seat was a bad idea. I also stuck the foam down straight to the bottom because I don’t like the idea of not being able to wash out between the grooves. Anyway before and after opinions would be nice

22ft Stingray boat

I came across a stinggray boat that has been sitting for 3 years and it's currently not running but it was running the last time it was parked. Any recommendations on what to look for when checking it out? Anyone recognizes what year and model could this boat be?

Thinking about going electric on a little fishing boat

Bear with me—I’m pretty new to electric boats and may be overthinking this.

I mostly fish smaller lakes, usually early in the morning, and I’ve started looking into whether an electric setup would actually make sense for that kind of use.

My biggest question is range. On paper, some of these setups seem like they’d be plenty for a normal day of fishing, but I’m curious what that looks like in the real world. Do you actually stop thinking about battery level after a while, or is range something you’re always keeping an eye on?

For anyone here who fishes with an electric setup, how long are you typically out, and have you ever had range become a real limitation?

Would it be ok to lower the cockpit sole closer to the water line?

The red lines and text are my edits. For cockpit drainage, I am thinking I could just add scupper flaps or duckbill scuppers, but don't have any experience with either... maybe I am overthinking this. I am open to ideas that don't involve raising the roof.

Best way to seal outboard bracket?

The bracket for my outboards fills with water due to deteriorated caulking. I don't know what was used for caulking before, but what would be the best/durable product to usee to reseal the seam between bracket and transom?

We already have enough weight with the motors and should be better ride for the bracket to have some bouyancy :)

Question about Re-seating a deck hatch with a hole slightly too big

Hi all! I picked up a Chesapeake Light Craft Skerry from an amateur boat builder and found that the round screw-in hatches at the bow and stern that seal the flotation compartments were set into holes that were slightly too big and were messily sealed.

To correct this, my plan is to cut plywood collars large enough to provide a solid mating area between the deck and the hatch, glue those down to the decks, and then screw and seal the hatches through both where possible. this will raise the hatch by the width of that plywood, but if I make a nice smooth tapered transition between the collar and deck, I don't think that should create any new problems.

Is there an easier solution I'm overlooking here? The hatches are only slightly too small for the holes, and the collars do fully cover them, but my concern is that the screws on one side don't fully meet wood. I may be able to simply put screws through them closer to the collars' edges on that side and use an adhesive sealant to attach them, but I'd like to solve this problem thoroughly!

Johnson 70 HP 2002 - Rough Idle

So a friend and I bought this AMF Crestliner boat 1976 with a fairly new engine (Johnson 70 2002) and went through the process of fully repairing the floor: tearing it out, new stringers, new fiberglass, gelcoat etc. Then, we got to the engine.

I replaced the VRO pump with a common direct pump and did a 50:1 fuel/oil ratio. I replaced the timer base because the old one was cracked. I did a full carb rebuild and cleaning. Even tried replacing the power pack (ended up keeping the original).

Finally started up, but runs really rough on idle.

There is a lot of whitish smoke coming from the engine, the spark plugs appear sooty, and the engine is kicking a bit. I have to start it on high choke, but if I reduce it enough, it just dies. In the water, I had trouble shifting it in to gear as it would immediately die when not in neutral and without high choke. I've checked the sparkplugs - fine spark.

At this point, I leave for school in about a week, and really want just one day out on the boat after three summers of constant repair and before I leave.

What should I check first? Has anyone had the same problem? Any suggestions would be greatly appreciated. Thanks.

DIY 50 foot yacht restoration (Before & After)

My wife and I spent three years fully restoring our sailboat, pouring in countless hours of hard work. Living in camper beside the boat in a boatyard on the Chesapeake Bay, USA, we replaced just about everything but the hull.

We used Sapele Mahogany for the majority of the interior joinery as well as some structural elements like the 17 laminated deck beams, bulwarks and the strip construction rudder. All of the white surfaces are rolled and tipped Meranti marine ply and the saloon table is Australian Red Cedar. We rebuilt every aspect of the boat, from the rig to the keel and everything in between.

We took on more than we ever imagined but the result was worth every drop of blood, sweat, and tears. Here’s a glimpse of what we accomplished.

Edit: thank you for the overwhelmingly uplifting comments everyone. We are very humbled by everyone’s kind words. For those of you who would like to see more photos of the rebuild, we documented it over the years on our instagram account @trim.sailing

Advice on what yall would do to improve this boat.

Hey yall, I bought this 1648 Jon boat a couple weeks ago for a pretty good price. It’s got a hole in the bow because some idiot towed it without a roller (it was me). What’s the best way to go about fixing it? Also, the previous owner cut out the transom support legs, should I Jerry rig a replacement, or should it be alright. I plan to redo the transom some time soon, because I think it needs it. I want to add a decent floor for standing and casting, but I want to add seating too. What would yall do if this boat was yours?

CNC core blocks for hull form and less filler in kerfs.

Hi guys just curious about your thoughts for a build technique.

Im day dreaming about building a 40ft multihull (proa) out of end-grain balsa. The traditional method of filling the kerfs with bog adds weight and is brittle at those points and require a fair bit of fairing.

As a alternative I'm looking at "knitting" the core.

Essentially I'll have a female frame/jig ( CNC cut frames and battens.

Then looking at using a CNC machine to cut core blocks of end grain Balsa (300mm X 300mm x30mm) the inside and outside surfaces machined to the hull surface and lap-joins with finger joints cut on the adjacent joining edges. A big puzzle. The frame/ jig is essentially for supporting the weight. Starting from the middle and working to the ends 1st to establish a center the blocks are glued in place, then repeating the process out to port/stb at the same time. This should make a Balsa hull form that's relatively accurate to its design. Then the inside will be laminated and bulkheads/ stringer's. Could possibly do the deck with temp stringers but for now ignoring the deck. The hull flip and outside skin laminate is pretty standard. The build would be in Indonesia ( I know they grow alot of Balsa, not sure how much of the manufacturing of end grain sheets is done there.

A 4x4 CNC machine will be used so multiple blocks can be cut at a time by cheap but trained Labour (I'm not slave master they will still be paid above and locked after).There will be alot of block's.

I'm aware that balsa dosnt like moisture and this will be mitigated.

Also ideally I would like to vacuum bag so if anyone has experience with vacuum banging Balsa core that isn't in a sealed mold I would like to hear ya thoughts could look at infusion. ATM I'm thinking of going above the gunnel. Having a strip of malone to bag onto and having a bag under the core to envelope, the glue getting on the bag going hard / sharp blobs would probably require the hull to be lifted ( pre glass) and a quick sand before placing the bag and the hull back down.

I'm also curious if the glued joins would be enough to make a acupuncture hull shape and strong enough to hold it.

The cut files will be outsourced to avoid inaccuracies.

Happy to hear the community's thoughts.

I have 3 years experience boatbuilding nearly 20 years ago, we made plugs- molds and infused foam core. So I have a little experience but understandably a big project.

How We Align 9 Stations With Just a Laser Level

Quick demo: 9 stations on the ladder — including Stations 5.5, 6, and 7 — and how we use a simple laser level to get perfect frame alignment. No fancy tools, no guesswork.

This is a short technique video. Don't confuse it with the big cockpit sole video coming soon — that one will cover the full layout separately.

Odd old shaft coupling on a 70’s Trawler.

It appears as though there is a retention bushing threaded onto the shaft, inside the coupling.

There’s a gap between the outside of the bushing and the coupling.

The bushing is larger than the diameter of the shaft, so will not exit the aft or fore of the coupling.

Shaft tapers down from 1.5” to 1” as seen as the smallest circle in the first picture. Looks to be threaded visually, and the set screw to hold the coupling on was pushing into the bushing so they must have trusted its connection to the shaft.

Coupling is obviously keyed onto the shaft so there’s no spinning them independently without finding a way to grab that bushing/collar..

I’m stumped.

Anyone seen one like this before? Any advice on removal?

Edit: Solved! Brass register is removable, revealing holes for a spanner to remove the “nut”.
