When did boats stop using wood stringers?
1988 was the last year for wood stringers. From 1989 on they had no wood in the hull.
How important are stringers in a boat?
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. If you are buying a boat, especially used ones, stringers are one of the most important things to inspect.
Do all fiberglass boats have wood in them?
Most fiberglass boats have wood in them. Sailboats travel more slowly and depend more on hull structure for strength, but even so they often have glass-encapsulated wood stringers, engine beds, and lots of balsa or plywood cored decks.
New Monterey boats are made strictly from composites, so you don't have to worry about rotten wood. However, older Monterey boats may have wood underneath the fiberglass. This wood could be found in many structural areas of the boat, so it must be in good condition.
Grady-White stopped using wood in their boats in 1998. However, the company did not make the transition immediately. Instead, they opted for green board, which was still wood, but more resistant to rot than the previous marine plywood.
How Long Do Fiberglass Boats Typically last? Fiberglass boats can be sound and seaworthy for up to fifty years or more. Fiberglass is very durable, and with proper maintenance and care, fiberglass boats can last for many decades. Fiberglass itself will not break down but instead will break down due to outside factors.
Fiberglass won't rot but it will get brittle from UV exposure. That's why it's usually protected with a coat of paint or gelcoat.
Yes, fiberglass can and will absorb water.
Remember, stringers are structural support members. As you repair or replace damaged material, use your best workmanship.
A fiberglass laminate is very flexible, so all fiberglass boats rely on longitudinal stringers and athwartships frames and bulkheads to maintain the hull's designed shape.
Monterey Boats has been one of the top boating companies in terms of design and reliability for many decades now. When it comes to designing and manufacturing high-quality sports boats and yachts, these vessels are held to a higher standard.
Stratos went to all composite in the 1998 year models.
Monterey Lawn & Garden Products is a subsidiary of Brandt Consolidated.
Simply put, Grady-White Boats are expensive because of the premium quality materials used and how they are constructed. They are made of high-end engines, equipment, and other options, and all its hardware, including rails, cleats, and other fixtures carry the best quality.

Grady-Whites are built to be the safest choice in boating. Every third party study ever done in the marine industry has ranked Grady-White highest in its category. No other coastal boat builder has been highest ranked even once.
Most old fiberglass boats are cut up into pieces and then placed into landfill, but this is not a sustainable strategy as you can imagine. There needs to be an industry-wide initiative developed for the proper disposal and recycling of old fiberglass boats, but as yet, there is nothing planned.
The function of the bilge pump is to remove water that collects in the bilge, which is the bottom of the inside of the hull. Most of the time, water that collects in the bilge is incidental: It could be rain water or water from spray collecting in the boat; Or water from built-in coolers that drain to the bilge.
Fiberglass is very strong. A standard pice of PCB is 1.6mm thick. Try breaking a non perforated piece, you'll be surprised what it takes to do.
Gelcoat is a liquid that hardens to form a thick layer that's used to protect fiberglass and give it a shiny, smooth finish. Applying gelcoat to fiberglass is simple if you have the right tools and take care to mix your gelcoat properly.
Sealing fiberglass is a necessary step to protect and even out the finish. Fiberglass is slick, and many paints will not stick to it if the proper surface preparation is not complete. Other than that, there are few differences from sealing wood or metal.
Boat stringers are wooden lengths typically found in older boats or pre-fabricated fiberglass molds in newer vessels. They are designed in a lattice or grid system to create a supporting structure underneath a boat deck. Stringers are similar to how joists would hold up the floorboards in a house.
The boat stringers main purpose is to offer structural support on a boat and are situated underneath the boat deck. The boat stringers in older boats are usually made out of wood. The wooden stringers are then laminated or can be covered in fiberglass.
As for thickness, 5-6mm would be fine for the stringers. The stringer grid is made a bit thinner, placed in the hull and glassed over to bring it to full thickness. Hull thickness should be fine as is.
Soft spots on the deck are a sign of rotted and delaminated core materials. Although these sometimes can be repaired, more times than not soft deck sections are an indicator of what is below the deck: a wet or rotted stringer system. Another area of potential concern is the boat's systems.
Look for any signs of transom bowing or deformation. Look for any signs of the motor mounting bolts and washers being pulled into the transom. If the customer knows his boat, he will not have any issues with you to tug up and down on the bottom of the motor with the motor tipped fully up.
Usually you can tell a water logged boat because it lists to the side with all the water in it. It's not the weight.
