Replacing these with windows that open?

As part of my ongoing retrofit and upgrade of the old S30...I want to get more ventilation into the cabin...So I was going to replace all 6 windows anyway...anyway to get the same shape window in something that opens and doesn't look like I just slapped it in there? As close to looking factory as I can get. Here is what they look like....I was really thinking of opening windows on just the largest ones in the rear only...the other 4 just replacing with new plexiglass.

Your just asking for water intrusion, your best bet is to replace with solid lexan ( or whatever ) and look for other options for improving ventilation; Maybe a couple of cowl vents on dorade boxes

I'm sure it could be done. But, what about getting a large nylon wind catcher for the forward hatch.

Beware of "widows that open"...;-)

I concur, that's too much area to make an opening window. Better done with a porthole, which will look goofy on your cabin design.

Re: Replacing these with widows that open?

I've always wondered why modern boats have gone away from opening ports in the saloon. The ComPac 23 looks very sharp with its 3 oval bronze ports and they open & have screens.

Do the opening ports fail that often? Or is it the fact that if they fail the failure is so catastrophic?

It sure would be nice to have some cross-ventilation at anchor.

I don't think you're going to find something in those shapes. Your best bet might be to find something oval or square slightly larger than them and just cut openings and install using the templates for the new windows.

But you'll have to take a good look at the existing windows to see if you could go larger with them.

Beckson makes song long ports like that with a middle section that opens -- but I'm not sure if they're THAT long.

Re: Replacing these with widows that open?

Those ports are actually relatively narrow so most opening port styles will be too big to incorporate. Replacing with opening ports is possible but it will totally change the look of the boat.

The Lewmar opening ports used on the Beneteaus (36.7, eg) might work here but you'll be totally cutting out what you've got and you'd have to find one that is larger overall than the portlight you're replacing.. and it won't be cheap. That may be complicated by an uneven thickness in the deck and/or distance between the deck inner surface and the internal liner.. these projects usually morph into bigger ones than they may appear at the outset.

Here's a very thorough page that stresses the amount of work involved.. and a result that you'll need to like the look of.... I'll bet that cost some coin besides the obvious work involved..

Re: Replacing these with widows that open?

Pappy is right - that style of deadlight simply can't be converted to any kind of opening port without screwing up the looks of your boat.

It looks like you have room on your cabin top for up to four cowl vents. Those plus a wind scoop for the forehatch should provide all the ventilation you need - especially if you spend the coin for some NICE stainless cowls, not those nasty PVC things. They won't cost much, if any, more than opening ports either and will be much simpler to install.

I, myself, personally intend to continue being outspoken and opinionated, intolerant of all fanatics, fools and ignoramuses, deeply suspicious of all those who have "found the answer" and on my bad days, downright rude.

Here is a picture of a boat with "those nasty PVC things" installed as cowl vents.
