opening port lights fitting surgestions

I have been looking for a while and my main problem has been the length of the original port lights and filling in the holes to fit opening port light.
The other day I was browsing ebay and cam e across some Trend port lights for sale and after thinking for nearly a week about it I put in a bid and won them




arft original port light the masking tape represents what the new port light wont fill approximately


The above is approximately the forward port light the tape represents the new port light where it would end.
Height wise there almost the same
But in saying that I will have to straighten the port lights similar to your boat . My original port lights dont have parallel lines

exterior trim



I have 4 of the longer ones.
So far there in transit should be here tomorrow.
But have been thinking how I will do it .
One of my thoughts is fit a piece of teak to the cabin side and inset the trim into this . Looking at the cabin side of my boat I am thinking it looks a little plain fitting some teak there and fixing and sealing to the cabin side would enhance the cabin side.
One of the things with these portlights will be the thickness that I have to work with . I may after looking at it for a while, laser the trim down this will reduce the thickness. I will be making a interior trim for the port light so it fits in with my interior cedar cabin sides so this also will assist in reducing the port light thickness.

So I am wondering what opinions are as far as adding an exterior teak timber to the cabin side will it look ok

I will add also the same seller still has 4 of the smaller port lights if any one wanted his contact details PM me

Hi HG

How much of a drama would it be to fibreglass up the opening to the correct size

Regards Don

I will do that Donk its not a large area. The main fitting problem will be the port light thickness I have to reduce it. These were purchased for a 50 foot boat build that did not get off the ground. One of the reasons I bought them is there width and height They nearly cover the old port lights cut out
I do own a plasma cutter never used it on stainless might test it out of some scrap them make a jig to reduce the shroud thickness down and a good polish thats another idea

Hi HG

Just wondering if they arrived

Regards Don

Yes Donk but I went to watch Bob Dylan I added a few photos on another post


I put it under what did you do to your boat today . Ill redo tomorrow night proplery off to bed

Two parts portlight and external shroud


The portlight is fitted from the inside and fixed to the cabin sides with screws and sealant. in this photo the tape measure
is sitting on the leading edge which would be inserted in the cabin side cut out from the inside of the boat.
There is absolutely no instruction or recommendations with these ports and non on the Trend Web site. Ill take a photo of a side view of the above tonight.
The photo below is basically a trim on the outside of the boat. Which I call the shroud want for a better name but its dept can be cut down . To suit the depth of your cabin sides.
What Ive been thinking of is making a teak spacer for the inside which would fit on the above port light face as above. to move the port light back towards the inside of the boats interior. It would be made also so its wider than the out side edge of the port .
this side is facing the cabin side and as you can see its wider on the other side along with a gap(off set) which would cover the ends of cedar strips of the cabin sides when I fit the interior trim.

Cisco would have fitted several port lights over the years Id say he might add some information

I might still get away with out cutting as the exterior shroud slides in and out on the port light
As long as I make a teak spacer for the inside and maybe one for the outside shroud
I might not have to alter any thing on the port light
If I can is rather not alter the port light what so ever
