Structural integrity of large glassed areas on say, Westport 172

Not only that but sea sickness. Yes the big windows look nice at the boat show, but I still remember my first bout of sea sickness. I awoke on my 4th or 5th day out and my eye immediately went to the TV screen which reflected the waves going past my porthole. From that moment I spent the next 2 days puking up everything in my gut and when empty I kept right on puking. Can't imagine waking up to seeing the waves going by a big window right at bed level. Then there's the wonderful view from the slip of the hull 3' away. Maybe if you live in a NYC apartment that seems normal, but I'd rather just see my SR till I get up on deck. Then there's the panic one will feel when they see that eventual first trickle of water coming in the seam between that glass and the fiberglass hull a foot or two above the waterline.

I agree, pretty and airy has risen to a new level, time will tell how well those glass walls and large hull windows hold up. A roomy shaded aft deck is hard to beat.

Since you are all going off the deep end in response to a question regarding glass on a Westport, I ask this simple question, how many known instances of glass failure on a Westport do you know of? As one who owns a 130', I am not concerned. I am not aware of any issues and don't anticipate any and wouldn't hesitate to purchase the 172.

Exactly....

The thread title says "on say, Westport 172", but it applies to a lot of other boats I'd be a lot more concerned with. The bigger the boat the stronger its components, and I'd have a lot less concern with a 172' of any brand than I would with a 50' or a 30' which are also sporting these hull windows. I'd also be less concerned with a newer boat than one that's been flexing for 10 or 20 years and thus shortening the boat's lifespan and lessening its resale value. I also wonder about how these windows are holding up visually to brush marks, fender rubs, soap, waxing and oxidation. Personally I hate looking through dirty or scratched windows.

The owners of these boats won't likely be out in rough conditions but the crew will be when they're trying to move the boat to meet the schedule.

The first owner won't care much, but subsequent owners will when they pay for the repairs/replacement of the windows and lose a season for it to be done, lose resale value or experience premature demise of the boat. And yes crews will care when they have to report leaks

Just looked at a Westport 172. online. Wow, a lot of yacht. I did notice the tri deck with a lot of large vertical glass and large hull windows, probably what the op was concerned about. You own a Westport and not concerned so that is good enough for me. I do question the large hull glass windows same as most that commented, in no way demeaning Westport, their reputation is well known for quality.

Me either! lol

Elon Musk was showcasing ALON which is ceramic aluminum oxynitride not glass at all. Of course it comically failed but it is actually much stronger and lighter than steel. Currently too expensive and small but very exciting futuristic material.

I am unimpressed with the use of glass on boat hulls. We won't know how it holds up for years. The "look" adds nothing to a yacht's eye appeal. Maybe that says more about me than the boats!. For some more glass information Google "Chicago tower glass". If it was my $$ on the line I would hire a consultant after getting as much information as possible from the builder. Maybe the tower glass engineers mentioned in the google search would help. Good luck!

Westport would probably build you a 172 without the hull windows. Floorplan shows a lot of topside glass, not unusual for a boat that size. Says room for Captain and 12 crew, not a problem keeping glass clean.

Purchasing new I wouldn't be too concerned about the glass on most boat hulls, but I envision big problems for the person who buys them 10 or 20 years later between scratches and leaks. Normally someone buying a 20 year old boat doesn't have to worry about being the boat's last owner, but with windows in the hull he may well be. When that'll affect the resale prices I DK, but I'm pretty sure it will.

Are you referring to The Bahamas? There are very few places in the Caribbean where draft is much of an issue.

I just looked at the W172 spec. 7'9" is a very slight draft. Not even a problem in The Bahamas.

Yes and no. There's the way the average 80' boat does the Bahamas and 5-6' allows them to get in and out and cross where they wish. That's not the way a 130'-200' cruises though as they'll anchor off and tender to and from and go to deep water marinas and among those boats you'll see 8-10' often.
