Need a new teak table for your boat, Call Goodale Marine today
Fairly straightforward to build if you're handy with woodworking. Two problems with fold-up tables: The hinges are more visible than fold down tables; and there is a lot of stress on the hinges.
Stainless steel piano hinges are probably the strongest for the money, but still - if they get someones weight on them the screws will pull out of the wood. It might be worth considering a folding support bracket underneath as well to give extra strength. At least you arent banging your knees like with the fold down type.
Another option if you have the storage space; a second smaller table, and swap them out as required.
I'm debating the same thing.
