There are 3 stringers, all of which appear to go all the way to the front. I can see that I will have to take out the fuel tank to get up there to replace them. So here are my questions about that.
Am I going to need to cut parts of the "dash" apart in order to get that out, or am I missing something? While it would suck to have to rebuild that Im sure it can be done. I can see where the only part I would have to cut out is about a foot and a half up from the floor, right above the step that goes up on to the front of the bow (this is not an open bow boat, but the window does swing open for you to stand up there). here
I'm pretty new to this so im not sure what the "tabbing edges" are. From what I understand they have to do with the bulkheads and how they're attached to the hull, but this is talking about the fiberglass.
"When laying out the layers of fabric, do not allow the tabbing edges to end at the same place. For stress reduction, step the edges of the fabric to create a tapered edge." [links]
Anyway, my boat is a Marquis V170 Stingray. When I bought it, I knew the motor was bad, and knew the front mount needed to be replaced. When I got down there to replace it, I saw that there was a lot of rotten wood around it. A few inspections and Sawzal cuts later, I've realized that the stringers need to be replaced; front to back. The whole 9 yards. This doesn't bother me that much since I basically only paid for the trailer, and only paid $550 for the motor that is going to go in it, and I was in need of a good project anyway. Today I've started cutting out the floor, and as I go I will probably keep asking questions here but I've got some right off the bat before I really get started.
Stringers do more than just support the hull. They serve as the foundation for the deck and the bulkheads as well. This means that the strength of stringers serves to support the entire boat even when they are found only at the hull of a boat.
Stringers on boats are extremely important, and we hope that this short guide was able to enlighten you on their importance to you and your boat. Now that you know what are stringers on a boat, we hope that you can give this lesser known boat part its due attention.
is the traditional boat stringer material used. With wood, stringers are strong and flexible. Wood has been used in boats for a very long time, and this fact serves as a testament to how effective wood stringers are. more
Vibration and impact on the fiberglass can cause stress and fatigue. Repetitive waves, engine vibrations, and other activities can cause strain on the fiberglass.
Some factors that will affect break down are:
In this article, we will look at how long fiberglass boats last and the factors that impact fiberglass boats’ durability.
Salt from saltwater can move between the fiberglass and become deposited in the fiberglass’s larger porous areas. This causes the salt to add to the pressure on the fiberglass.
Therefore, you will have to adjust the core material by rounding off the top edges. You will also have to round out the inner corners between the core material and hull and between the core material and bulkhead. [links]
Take the first piece of your fiberglass skin, which is the largest and place it over the stringer and apply the resin and hardener mixture. Remove any excess epoxy, but make sure the entire surface has been soaked through. [links]
You can easily fix these holes again if you do not find anything, but if there is a problem, this will save you in the long run. Inside will be pretty dark, so using a torch and mirror may come in handy in spotting the problem.
To determine how many layers, you can take the thickness you want and divide this by the single-layer thickness of the fabric you will be using. here
When there is existing fiberglass, grind a 12-to1 bevel on the stringer. The new fiberglass will then attach to the old and provide a surface area which offers even support. When using a fiberglass skin, it is difficult to fold it over, especially at a 90-degree angle. [links]
