I think the actual design and manufacture of the hulls is a pretty consistent product. The weak points in virtually all production boats seems to be flaws in how well third party systems are installed and integrated. I think those areas are where the lowest bidder becomes the supplier. And where poor installation
practices can become aggravating even if they're not necessarily dangerous.
A good example is our aircon system: There was an installation
goof in that they were mounted slightly off level such that the condensate tray didn't properly drain which leaked water
into the bilges. On top of which the aircon tray is galvanized steel
and these trays tend to rot
out. We replaced our tray with a fiberglass
unit - but the question remains as to why something as expensive as a marine
aircon can't be built in a more idiot proof manner?
Or sea strainers which are quite well made but so bloody obscure that you can't find a replacement mesh easily? (We did, but have to ask ourselves WTF as to why the boat didn't come with a list of vendors for all this stuff.) I've had the same conversation with owners of virtually every major brand of yacht.
There are many engineering and design considerations. On the drawing board, I think the Leopard use of balsa core (higher sheer strength) throughout the hull is a great design with great use of materials for maximum strength to weight ratio in this price range, but in the long run I would not feel comfortable with this construction because of fears of water intrusion in the core.
I have the same reservations. One acquaintance with a very well made boat had problems with the foam core because through hulls were installed without sealing the cored areas around them. If it had been balsa the moisture would've wicked further and perhaps been more difficult to resolve.
Another friend had water leaking from the light fixtures of his balsa cored bimini
because the fasteners weren't gooped in. That's been fixed and it will dry out, albeit slowly. Nonetheless, it's a stupid 5 minute job that some installer forgot, or couldn't be bothered to do. In the meantime, he's dragging around a hundred pounds of unwanted rainwater in his bimini
The Gunboat engineering is great but you pay for it. Best of all is the Boeing's epoxy carbon fiber composites built by RTM and cured in an autoclave which are used for the F-22 Raptor, but look at the cost of one of those!
F-22's are great going to weather
, reaching and they tack beautifully. But the anchor locker
is rubbish and there's no room to park an Eskie with cold beers.
