Have a question for ya all, not sure if this is the right area vs Project boats. But here goes.<br /><br />I have a 21ft cuddy cabin it does not have any portlights in it. I am thinking about trying to put two in, one on each side. Is this advisable, and or should it be left up to a professional?<br /><br />Picture of boat<br />

Re: Portlight Install

It can be done. But it is also very messy work, if you have a weekend that you can spend devoted to this project then go for it! If not it is best to leave it to the pro's.<br /><br /> But here is how! The first thing you need to do is make some templates, if you plan to install two on each side you will need eight. Figure out were you plan to mount the portlights and tack up the templates on the outside and INSIDE the cuddy cabin. Make sure that it both looks good inside and out, AND that it does not take away from the structural integrity of the hull.<br /><br /> Once you have figured out were to mount them, outline the cut-out opening and trace it with a black sharpie. Drill hole on the line with a large bit so that the blade of the saw can fit through it. SLOWLY cut out the portlights opening. Once the opening is cut out dry fit the portlight and the backing plate, sometimes the backing plate will not be flush and you will have to make a make a plywood shim that allows you portlight to mount flush with the inside of the hull. Once you are done making the shim epoxy it to the inside of the hull. <br /><br /> Finally dry fit all your portlights and mark where you have to drill the holes for the bolts or screws. Drill out the holes and dry fit the portlights one last time, but this time bolt them to the hull to check that everything lines up correctly.<br /><br /> Now is time to get out the 5200 or which ever sealant you plan to use, BUT first with every portlight removed you will need to sand around the cut-out hole to remove any wax, then you will need to clean each portlight to remove any dust or oils. Use painters tape to cover anything you don't want sealant to get on and wear some old clothes. <br /><br />Here comes the fun part, you now need to apply sealant to the port lights flange and smear some sealant around the opening in the hull. Slowly push the portlight against the hull and have a partner insert the bolts into holes. DO NOT fully tighten the bolts yet, Only tighten them 85%, you want to wait 24 hours then come back and tighten them all the way.<br /> <br /> Now you are done installing the portlights, all you have to do now is remove the painters tape (use a box cutter to trim the sealant) and you will be done. If you want to know more about boat repair, go to a local book store and buy the "Good Old Boat" by Don Casey.

Re: Portlight Install

Tallman,<br /><br />Why are you installing these? Additional light, ventilation? I had a similiar desire for both, so I added two new hatches on top. Much better ventilation and light. I don't know your goals are, but those little windows don't provide much, but often create a place to have water leak in...<br /><br />(perhaps not a good location for them on top???)

Re: Portlight Install

I don't I would say anywhere between 70-300 a portlight. It would be best to go to a BOATYARD to get this done, I boat yard will have boats set up on jack stands, and a trava-lift. Boatyards will have experienced employees and sometimes you can ask the yard manager if there are any DIY'ers that would do it for an extra buck. Don't go to an Outboard repair center or a "new boat" dealership, They will most likely have some un trained employee install them, not the mechanics and painters.

POINTER94:<br /><br />I am adding them to spruce up the appearance, add a little ambient light into the cabin, possible provide a little more ventilation and I hope increase resale value of the boat....<br /><br />Sloppy: Thanks again for the input. :D

Re: Portlight Install

Tallman,<br /><br />I worked several years for a large boat dealer and I will say we did have some issues with this style of port. Granted it was about 10 years ago and composites have come a long way but, we did have frequent rebedding and replacement of this type of port. I will also add it was primarily on sailboats.<br /><br />You may be looking to trade it soon and it won't make an issue but if you are long term committed you may want to look at a sealed glass port. Just food for thought. :)

Re: Portlight Install

Or a metal one, I like the brass ones, but I do not know what they would look like on a cuddy.
