foam core boat deck

choosing a deck core | boat design net

as an example, i know you are not going to build your deck this robust but i built the deck for my boat 20 years ago out of two layers of 1" balsa (because the original foam deck failed and was weighing the boat down with water. it was simply not strong enough to be the deck of a workboat).

sealing deck penetrations to prevent core rot photo gallery ...

most all boats have some sort of "core" in the decks. whether it's balsa, plywood or some of the foam cores all can eventually absorb water from a leaking deck penetration. a leaking deck, especially with wood cores, can lead to core rot and eventually delamination of the deck and loss of structural rigidity.

deck recore - lessons learned | sailnet community

based on my research balsa core is a superior core material. as long as it stays dry. i understand that even some of the foam and high tech materials are subject to water damage eventually if any gets to it. no matter what core i use keeping water out sounds like it is key. balsa is an excellent core, is easy to work with and is economical.

marine applications - carbon-core corporation

carboncore’s tough and rot-proof core will result in stronger and more durable structural boat parts; in addition, as compared to foam, balsa wood, or paper honeycomb, the boat became much quieter than before due to its inherent best in the business sound and vibration dampening qualities.

injecting structural foam into cored deck? any experience ...

i drill more holes, more reaming of the core with the wire hangar. you could shop vac it but i dont. i inject the stuff and it envelops the mush pushing excess water out the 1/8 straight thru drain hole. the boat in my side yard has had the injectadeck for 8 months, still a firm deck. bring your boat by, i'd like to try a section."

delamination of fiberglass from foam core on deck of 1973 ...

( on the boats built in the early seventies the foam wewas a very stiuifff urethane foam and it pulverized easily. by the time the boats with 20,000 numbers were manufactured, the builders had figured out the foam thing and no boat since has had the "wrong type of foam." that 125xxx boat mentioned above is now over twenty years old. i am one of ...

foam core boatbuilding | dedicated to the smallest of skiffs

the foam you are looking at is not the same as the foam board you would use in boat building, they have different densities. it has little strength in both compression and tensile ranges. basically you would flank it in glass but the core would be so soft that it would end up buckling if any stress is applied to it.

flotation foam for boats (types, benefits, recommendations)

the foam is there to literally prevent the boat from sinking. let me explain. if you puncture a hole or otherwise spring a leak in a boat without foam, that boat is going down and quick. on the other hand, a boat lined with foam will still take on water and will sit progressively lower and lower on top of the water but it will greatly delay the ...

how to fix fibreglass deck leaks - boats.com

no boat owner should risk being complacent about deck leaks – a fibreglass deck will eventually become structurally compromised if water reaches the foam or balsa core, resulting in much more maintenance if they are left. in theory builders of such boats should remove core material from the location of any through-bolted fittings.

the dryboat® process | dryboat® structural moisture removal ...

the traditional cure for wet core repair is very destructive and compromises the designed integrity of your vessel. the laminate is removed above or below the core, the wet core is removed and replaced, and finally the laminate is replaced. this is a nasty, costly job and rarely produces a product that is as good as the original.

eventually, there would have been, but since the boat is 20 years old, i was very impressed with how well the balsa performed over the years. yes, it’s heavier than foam, but foam cores have their own weaknesses to be dealt with, and it’s wise to replace whatever core was originally used with the same material.

one solid hull | regulator marine boats

to add rigidity and reduce noise, foam is injected into the stringer. the stringer and hull become one solid unit, so once the stringer is in, it’s in for good. the strength of the stringer and other core parts eliminate much of the stress at the deck, liner, and hull joints to deliver a difference you ultimately feel offshore.
