Wow!!!!!! you've got skills in sketchup. that tool befuddles me, starting and dragging to hit specific sizes is rough, no easy way to type them in. On a side note, notching the transom might be back on the plan. I called Bob's Machine shop and tried to order a Jackplate and they told me 6-8 weeks. I...

that seems like a really nice trailer, torsion axles each rated at 5k. disc all the way around. Nice!!!!

Cam.

I like the idea of using tape, I generated a bunch of firewood yesterday and don't want to keep wasting if I don't have to. Once I get the profile right I do want to make it out of OSB to make sure It works as expected as well as use it as a test bed for how to set up the helm

oh, here's a boat that I like the looks of padebco 29 CC

is there a decent technique for taking an image and rendering a scale model of it?

ktm_2000

I didn't have grinding / laying fiberglass in me today so I decided to have some fun and to some design of the doghouse. I picked up 3 OSB panels and started messing drawing and cutting. I drew this image a while back based upon the hull drawing I found here. The drawing is 2d and doesn't account fo...

this last post is going to help me quite a bit, the nida core I laminated for the deck is 1" thick and it will sit on top of where the original deck would have sat. I'm probably going to have to deal with the same problems you have as well. I'm becoming more and more convinced that I need to buy the...

when life gives you lemons, make lemonade. One of the best days I've had bass fishing was a day I was supposed to go offshore. Was on a buddies boat and we left the pamet river and was going to go east for tuna, we rounded p-town and just off the back side, jigged up 100 macs and when we tried to ge...

WaytooSlow, I sent you an email. This weekend was busy, my goal was to laminate 3 panels of nidacore. Friday it stopped raining at 3pm and seemed dry enough by 6 that I felt safe so I laminated one side of a piece of nidacore. Saturday morning I setup another laminating table and did the second side...

ktm_2000

btw, you were right about the layers of glass to fill the I/O cut outs. I did 4 layers and will need to add 2 more.

ktm_2000

Cam, Your boat looks amazing, I love the wood trim on the dash. From your pics, It looks like I could get away without notching the transom, it seems that about the point where the motor would hit the transom the prop would be exposed, not a lot but it would be exposed. I'm thinking the 12" or 14" s...

got some work done this week, glassed from the hull bottom up onto the stringers and transom in the motor well area. The color difference is because I used the fast hardener. https://photos.app.goo.gl/3giQc3vEXYRczy6x5 I also got the transom prepped to glass the I/O holes. It seems like the vertical...

ktm_2000

Cam, I'm getting ready to pull the trigger on a Bob's jackplate. What do you think of the powder coating on it, is it worth the extra increase in price Did you do anything special in preparing the glass on the outside of the transom to take the extra load of the bob? The reason why I ask is that I a...

ktm_2000

Your appetite for interruptions being low pretty much excludes keeping the motors as is and fixing as needed on a long term basis. There's no way that they are not going to nickel and dime you as well as have you miss trips because of various problems. your other 2 options both will require glass wo...

ktm_2000

lets start with the basics... What are your goals in owning the boat? how do you plan on using it? How are you planning on storing it? on a trailer ? in the water? Freshwater / Saltwater? Are you mechanically inclined? how do you rate your willingness for interruption? how fast do you want to be abl...

Thanks Cam, I did not know that about vinylester resin. I haven't purchased any of it yet, was planning on making a bank account reducing run to LBI Fiberglass tomorrow morning before work. The one decent thing is that I plan on using the bulk of this material in the next 2 months so it won't matter...

ktm_2000

I found this article - looks promising synopsis, let epoxy cure out, wash with soapy water and scotchbrite to get rid of amine blush, let dry, sand appropriately then the surface should accept vinyl-ester fairing /gelcoat. https://www.epoxyworks.com/index.php/applying-polyester-gelcoat-over-epoxy/

Hi folks, In my project I've been doing most of my structural below deck repairs with epoxy resin. Most repairs and work areas are now at a state where there is a solid layer of 1708 set in epoxy. When I do my deck and doghouse I was planning on doing the whole job in vinyl-ester and then fairing ou...

Hi Mike, I have a rather large google photos library and want to stick with that for sharing, I know how to link using the url tag but can't seem to be able to find a way to link via the img tag. I had looked at an article which stated that you could share a pic directly and bypass the google page. ...

ktm_2000

Saturday I glassed the port side from the base of the hull up onto the stringer in the old motor well area. I did 4 layers of 1708, I also overlapped onto the transom 8 or so inches so now there should be 8 layers of 1708 going from the transom onto the main stringers. With snow in the forecast for ...

ok, I was reading posts on other sites on how to post photos directly without posting links, I guess it doesn't work as expected.

I'm going to take a crack at this on a somewhat small scale this year and try and fill the weave aft in the cockpit area so only 6' off the transom. My plan was to sand the existing inside hull just enough to give the resin something to grip on, from there a layer of 1708 + 1.5 oz mat. I was going t...

my spreadsheet tracking costs is growing, growing to a point which could make your wife's point. on the flip side, I've ridden on a bunch of boats and not many can match the Bertram's ride, the ones that come close or exceed it and have brand new power are WELL beyond what I am going to spend for my...

ktm_2000

Cam,

I didn't read your post thoroughly, I have to admit I probably have similar issues. Being happy to get out of work to get myself into a pretzel position and spreading epoxy befuddles my co-workers.

ktm_2000

when good weather is here, got to take advantage of it... plus I had no ambition to do any sanding so I stayed away from the transom. so I put the final layer of glass in the starboard fishbox - the slow hardener from LBI is a PAIN to work with, slow to wet out and real tough to bust air bubbles. I ...

Andre, I think we are having a tough time trying to describe the same thing, just to get definitions right, what I believe the definition of chine is the point where the bottom transitions to the side of the boat. Here is a pic I've saved from another person's project. If you look at this one, and i...

ktm_2000

That ford must be a beast. I would have thought you'd need a dually to do what he is doing carrying the boat on top.

Most 3/4 ton trucks are good for carrying at least 2000# but I would think the work body would be pretty heavy

ktm_2000

what do you think of the guy's video where he reinforced the hull side to transom joint? is it needed?

ktm_2000

Andre, usually if a boat has a curved deck it is side to side with the highest point being in the middle of the boat I think the term is called camber and it's done to make water run to the outside of the boat. I'm guessing what you are not describing camber but are describing the relationship of th...

Yes Sir it was no fun, I'll be surprised if I can stand up straight tomorrow morning. I managed to get out of another meeting so I started at 2, sanded for 35min to make sure everything was good, I took off a bit off the top so there would be a smooth transition. I also cut down how much extended on...

ok, lets see if the weathermen have got the forecast right for tomorrow..... they say 68 degrees with the threat of some rain late, the boat is covered so I'm not worried about the rain but am worried about the temps. Hopefully I can get the glassing done and put a small electric heater set on 70 de...

another question on the rod holders... did you leave the wood underneath the gunnels which was there to take the melamine cockpit panels?

ktm_2000

Cam, I need more pics than that for inspiration. With all the high quality work you've put into the boat, I'm guessing there is quite a bit of "BLING" getting ready to go on her, lets see some of it. I only need a small amount of convincing in order to change my mind and blow my budget. Are the rod ...

Yes those wheels were tiny, the Bertram was way too big for that trailer (it was for a 22' boat and rated for 4000# ) even so the Bertram made a 1000 mile trip home on it. My current trailer is much more substantial.

ktm_2000

When I bought my boat I got it from Waukegan, IL and took it home to MA on a dual axle trailer rated for 4050#. I drained the tanks and took everything I could out of the boat which was detachable and heavy. I had spare tires + bearings, the tires got a bit warm so I was going slow and was regularly...

ktm_2000

Ouch, I don't remember paying that much for my trailer, but I didn't get rims or a spare tire. I doubt that you need the 9k trailer, I'd lean towards the 6900# one capacity wise as it is close to what I've run successfully for years but the torsion axles of the 6400# are somewhat appealing (I've had...

Cam, I will be making the doghouse out of 3/4" nidacore sides and 1/2" top so it will be fairly light, my estimate is that it will be less than 100#, I want the top as light as possible to reduce rolling. I disagree with your estimate that the boat will be bow heavy because Bertram designed the vari...

I've heard repeatedly that the center stringer isn't on later models and thus not needed, that is why I am considering using the space for drain hoses.

not to be a bearer of bad news but, the timing cover is behind the front motor mount and I do not see any practical way of holding getting at it without the alignment of the motor and the drive being messed up. You could possibly take the drive off, use some type of hoist to hold the front of the en...

I didn't get anything done on the boat due to the cold weather this weekend. I ended up selling my other boat to my buddy so I now have no good way of boat fishing so I better get serious and finish this project.

ktm_2000

Carl, B31 stringers are not that tall so plywood shouldn't add much of any strength in opposition to up and down load as there are only so 1-2 layers of ply going in the horizontal plane. I would agree with you that the ply might be used to keep it straight or to bridge 2 pieces of inner core to mak...

ktm_2000

not to be flip, what would 1/4" ply do against the load of 1000# of engine weight. In my opinion not much.

If you need more support in this area, I would be looking at reinforcing materials at a much greater scale.

ktm_2000

Sure, I'd love to see pics of your build and would appreciate ideas which would make my project turn out better.

ktm_2000

thanks for the info.

On another front, One of my friends suddenly got serious and wants to buy my other boat so I will be down to 1 boat soon with no clean way of going fishing. This Bert has to get to the point of being usable this year and preferably by July.

ktm_2000

Can you take more pics from further back so a bigger perspective can be had of the area in question?

I reinforced the inside stringer on the port side with 2 extra layers of 1708 today, all together there are 5 layers on the side where the stringer crack had occurred. The first layer was 12" wide and the second layer covered the whole bottom as well as stringer side to provide a good base for fairi...

Hotspot,

My B25 did not have this glass, I'm wondering if a previous owner put it in to keep water from being sprayed into the cabin?

ktm_2000

I took a 1/2 day off on Friday and got into sanding the fishbox area to put down one more layer of 1708 to cover everything up, on the port side which had the stringer crack I am going to do an extra layer. I then prepped to tab in the back side of the fishbox bulkhead as well as the front fuel tank...
