Re: Love, Necessity and Pride

You are really picking up some speed. The stringer layout/lines look factory... The glass work is really good as well. You got that 1708 to lay down without bubbles in some pretty tight corners...

Thanks PMC...hope alls good with you and yours...Actually used several small pieces, layered over each other. then one larger piece to kinda lock it all in...little bit of touch-up left to do...

Rain or not looks like you're moving right along.

Thanks TDF...I'm a tryin...

Hey, Gus, since yer a PRO now at all that glassin, would you come to OKIEVILLE and fix my KEEL???? I promise I'll get the trailer adjusted correctly and won't tear it up again.

Brother, If it wasn't for the price of gas, I would leave tomorrow and get it taken care of for ya...even bring up some of my low priced resin with me...free of charge...'cept of course for room & board...

Yep looks like typical Florida weather!
Nice work looks like your ready for the cross brace ..

Gettin there S.P., I'm gettin there...your new seating area and splashwell look awesome...

Well all the fires have been put out, boats have gotten wet, trannies are gettin replaced, new restores under way, Carp has happened, but everybody seems to have pulled through the weekend pretty much intact...hang in there...better days ahead...everybody have a great week...

Yeah, those are some great looking layups of 1708. The cleat work is outstanding as well, per usual. BTW: no risk of significant fire damage in a 3bench tinny I'm just saying....

GT1M
That is some fantastic work you are doing. It all looks great.
Like how your 1708 laid out for you. Nice and clear. Great job.

Re: Love, Necessity and Pride

GT, beautiful work and a lot of nice progress mad between the showers. nice work on all that glassing.

Re: Love, Necessity and Pride

The glasswork is looking awesome GT. That thing could withstand a atom bomb!

Re: Love, Necessity and Pride

Thank you, Gentlemen...oh yeah and my iboats buds, too...

I have a question regarding under the deck/mechanical locker ventilation...

I am still quite far from having to make decisions and designs on this, but I have been noticing something that I had not paid much attention to before now, and I am hoping you guys can give me a little education and insight...

The thing I have noticed is, irregardles of what type of under deck/mechanical locker venting design is used, be it on the aft sides of the hull, or aft top...is it always common practice to have one vent facing forward and one vent facing rearward

My OCD bothers me in that I would like to have both vents facing the same direction...

My only logical conclusion to this is to design and incorporate foreward facing, top mounted intake vents and rear facing, exhaust, side vents...

Ideas, comments???

Oh yeah and any resemblance of what might have been installed by the factory when new, did not exist when I got the boat, so any info on what the correct type of "ducting and connectors" are supposed to be used, would be appreciated...

As usual, yours truly,

 

[Trooper82]

Re: Love, Necessity and Pride

I have also noticed this. I came to the conclusion that when moving it forces fresh air into the vented area.

Yeah, I kinda figured if they point in opposite directions, it is supposed to promote some "flow-thru" even standing still...

Re: Love, Necessity and Pride

Gt, your boat is an outboard correct? Am I missing something. You should not need air vents, they are for evacuating fumes from I/O and inboards. Mine has a box on one with a blower to evacuate any fumes before starting motor. My vents are vented in both directions and they create air cross vent air flow.

Very good point CC...

I was more concerned with the mechanical locker which contains the fuel tank and at least two batteries, plus the fact that they were originally installed in the boat, though I am not sure about the details, because the exterior vents were there when I bought it, but I have seen other OB's with ducting installed behind the vents, leading to the mech locker...

This may well be something I don't have to worry about at all, but I just wanted to make sure...

 

[chriscraft254]

Re: Love, Necessity and Pride

If it was there originally you may want to put them in. Could be to vent any gas fumes and or battery fumes/gases. I am definately not up to speed on bass boat design, so don't take my advice. lol I was basing my thoughts onthe fact I have never had an outboard that had vents in the hull.

Did your boat have a blower switch at the helm anywhere? I will send you a pic of my louvers later when I get in. There pretty sweet looking. Chrome and black.

Re: Love, Necessity and Pride

Those vents are supposed to be in opposite directions to promote flow-through as mentioned and they are typically installed whenever there's a gas tank in a mostly closed compartment.

+1^....That is how mine are set up. However I plan on changing mine because right now the flow of air comes in above my fuel tank and goes out above my batteries. Yep...that is right....someone has my fumes pulling across my electrical system :facepalm:

 

[chriscraft254]

Re: Love, Necessity and Pride

If your boat has vents, it should have a collection box with a hose leading to were the vapors are liable to collect. And at the end of the hose should be a blower which will suck any fumes out via a helm switch that will turn thee blower on or off.. This is so you don't blow your boat up when starting the motor. Anything else is there just for air flow in the hull imo

Gas tanks have there own vents and any below deck fuel tanks are purposely in a closed section so fumes and any leaking fuel can't get to other areas.

If your considering vents, this style has the vents in one direction, but turn them opposite of each other for air flow and they look the same from the outside.

I know they have these in white as well, maybe other options as well. i choose the chrome/black combo to go with the rub rail.

For those that don't know, you should be running your blower if equiped with one for 5 minutes before attemting to start your motor. especially after fueling at a fuel dock.

Re: Love, Necessity and Pride

Those vents are because of the inclosed fuel tank and batteries, if I remember correctly they are USCG requirement.

 

[chriscraft254]

Re: Love, Necessity and Pride

If you have a inclosed fuel tank (built in) There is no need for ventilation if it has a protected ignition source. Vents are not required.

What the vents/blower systems are required for is for normal carberator boil off after shutdown of I/O or inboard motors which causes fumes to settle into the bilge areas. This is why you need to run your blower if you have these vents before starting the motor. There is also suppose to be a plaque that states run bilge blower for minumum of 4 minutes before starting motor attached close to the switch panel/egnition switch.

Now all that being said, "natural ventilation" is required for boats with built in tanks. Natural ventilation and powered ventilation are two seperate things and you don't always need vents to get natural ventilation.

Sorry, GT, but you asked and this is an important subject, sorry if its derailing your thread for a second.

FEDERAL LAW
183.610 - Powered ventilation system

(d) Each intake duct for an exhaust blower must be in the lower one-third of the compartment and above the normal level of accumulated bilge water.



The purpose of exhausting air is to remove potentially explosive or flammable vapors that accumulate in the engine compartment during normal operation of the boat. It is intended that the ventilation required by this regulation be sufficient to maintain safe operating conditions under normal circumstances. Ventilation cannot be relied upon to remove liquid fuel or all of the vapors that may be present if there is a leak in the fuel system.

It is important to evaluate each engine compartment design and locate the intake opening of the exhaust blower duct so it will be in the best position to remove any collected vapors.

The vapors that occur during normal operation are associated with carburetor boil-off after the engine is turned off. These vapors will flow to and collect in the lowest part of the compartment. The duct connected to the intake side of the blower is used to select the point in a compartment where the compartment air will be exhausted. The regulation requires that the exhaust blower duct opening be located in the lower one-third of the compartment. Refer to 183.630(b). Usual locations include:

•under an engine
•between engine stringers
•at a sump, possibly provided as a bilge water collecting point.



FEDERAL LAW
183.620 - Natural ventilation system

(a) Except for compartments open to the atmosphere, a natural ventilation system that meets the requirements of Sec. 183.630 must be provided for each compartment in a boat that:

(3) Contains a permanently installed fuel tank and an electrical component that is not ignition protected in accordance with Sec. 183.410(a).



OPEN TO THE ATMOSPHERE

Compartments that are open to the atmosphere do not require additional ventilation.

FUEL TANK COMPARTMENTS

A compartment containing a fuel tank that is permanently installed, as opposed to a portable tank or container, does not require natural ventilation unless the compartment contains an electrical component that is not ignition protected.


Just to confuse things furthur, in the federal regs, it also says that if you have anything other than a metal/aluminum tank, like plastic or fiberglass,etc you will be required to have natural ventilation depending on how much bleed through of vapor you get from the tank. :facepalm:

Re: Love, Necessity and Pride

Thanks for all of the responses and recommendations, they are greatly appreciated...

After doing some research regarding ventilation on a boat, I now know and begin to understand the importance of this requirement...

Besides finding the regs from the USCG that CC254 [now CC264...] has posted, I have found the following two references from BOAT U.S. ...

http://www.boatus.com/boattech/casey/ventilation-casey.asp

http://www.boatus.com/foundation/guide/equipment_5.html

Even though my floating tub does not have either a built in fuel tank [under the deck, enclosed] or an inboard engine...

The fact that the fuel tank is in the same compartment as the Batteries [ which produce Hydrogen Gas], the bilge and aerator pumps, plus a bunch of electrical wiring, and the fact that in this Florida heat, temps can get pretty stupid hot...
I feel that properly designed and installed ventilation is a VERY GOOD thing and I will be incorporating it my eventual design...

Due to the other information I have been reading about ventilation, I am also going to do my best to incorporate proper generalized hull ventilation to help prevent the other issues that plague boats, such as humidity, temperature changes, moisture, etc...which cause the types of situations where mold, mildew and fungus can begin to fester and begin the boat destroying effects of rot and decay...

As is always the case here on Iboats, this is an ongoing education and thank you all for your insights and inputs...

Now, if it would only stop raining everytime I get home from work early...

Have a great humpday, everyone...
