Grinding went well today. Helps when you have a good grinder and the proper disc. I got the engine area cleaned up and ready for the transom to be installed

Looks good, now its all building!

With having a few extra days off this week I got the transom clamped in this afternoon. Now it can sit for the rest of the week while we are in Minnesota.

When I get to the stringers next week I am going to do laminated stringers instead of a one piece 2x6 that the boat came from the factory with. After all wouldn't a laminated stringer be stronger then a piece of construction lumber?

My guess ... anything done with care is bound to be better then the quick slap it together and get it on the show room job that most G/C's had.
Bet when your done Brandon ... That CVZ will out last you ... LOL

I plan to make my stingers out of plywood too. That's been recommended by others in the club and I agree they'll be stronger than the 2X6's that came out.

Looks great Brandon, I would go with the plywood stringers as well.

I hate to be the voice in opposition, but bear with me. Dimensional lumber has the grain oriented in one direction providing for a stronger vertical strength. Plywood on the other hand is designed for horizontal, not vertical loading. This occurs from the various layers having differing grain orientations. Someone is likely to comment on parralams, or engineered lumber, but again, they have various layers, but the grain is oriented in one direction only. Now on a transom, your loading is designed for plywood to distribute the forces across a wider area. In wet conditions, I would prefer solid wood over a laminated piece. Consider this folks, which rotted out worse, your transom or your stringers? Now which one was likely to have moisture locked against it longer. And lastly, what did Glastron factory use? My $0.02, Michael.

Good points Mike, the joists of a house support alot of weight.

Plugcheck · « **Reply #52 on:** August 12, 2015, 12:41:56 AM »

I have used parralams in my home to reduce height, one is 18 foot long, supporting 14 floor joists. Yep, they are nearly as strong as steel. I think Art Carlson was way more passionate in the design of his watercraft than I will ever be as a hobbyist. I've looked at the overall construction and he really did not compromise much given the state of the art in his day. My Z will likely outlive Me given indoor storage and decent care.

OOooo... OOOooo...
A good wood fight ... LOL

I don't know enough about the subject to offer an opinion .. But ...
What do you think about the "Composite boards" for stringers ?

Plugcheck · « **Reply #54 on:** August 12, 2015, 08:04:30 AM »

Honestly not much experience with composite stringers or other similar Marine construction materials. Would not mind hearing about them from someone who has experience to offer their opinion. I seem to remember Doug mentioning a friends craft having such installed, but that it made it heavier.

Hull grinding is complete! All prepped and ready for stringers.

Tomorrow evening's project peanut butter where the transom meets the floor of the hull and cut lumber for stringers!

Now comes the fun part!

Looking good, Brandon. For what it's worth I went with 2x6's for my stringers. My thought is the wood is a core material and the fiberglass bears most of the stress.

75starflight · « **Reply #58 on:** September 13, 2015, 12:40:47 PM »

I opted to go with laminate stringers so I am building them today. I do have a question for those that have gone this direction in their rebuild.

For the bulkheads I am leaning towards interlocking them into the stringer so they go a stronger structure, would the be a wise idea?

That's what I did on my 23
