Re: Wood, Steel, Fiberglass . . .

Kind of what I'm getting at ..people usually answer with the maintenance answer and not enough buoyancy info in severe situations . I think we should be more informed . Thanks guys .

I looked over some test photos of unsinkable power boats years back and the problem was as you say, staying level. As I recall they tended to float with the engine way under water and the bow in the air.

Then there was the ad for Boston Whalers showing a boat sawed in half with people standing in both halves still floating. It's been a while and I could be wrong but I don't seem to recall an engine on the stern half.

You could apply the same to a sailboat if you had exploding keel-bolts to drop the ballast. Of course the issue of turning turtle would still be a problem.

There are more wooden boats on the sea floor than anything else.

Re: Wood, Steel, Fiberglass . . .

Choice of hull material is in the eye of the beholder. All require maintenance albeit in different ways and frequency. If you love plastic, go for it. Steel, again go for it. As for wood, well that's where it all started. It's individual choice. If your heart isn't into it, don't own it.

In response to Stumble........"more wooden boats on the ocean floor than anything else". Stands to reason doesn't it? Lots of old cars in land fill too.

The French Etap manufacturers sell unsinkable yachts. They even opened the through hulls on one, filled the boat and sailed it home. The foam is spread out throughout the hull but still leaves a substaintial space inside as a yacht. GRP isn't that disimilar to steel.

Through the years, I've personally owned all 3 types of materials and I agree with everyone that each has their own pros and cons. It just depends on your cruising agenda and needs and time.. Good luck

Re: Wood, Steel, Fiberglass . . .

It would be great if some experts builders and designers would lay it all out for us . Lets say if you were wondering " What If " ....

Boat fire...
Standing rigging integration...
Knock downs...
Handling seas ..
Haul outs ...( do marinas charge more after a certain weight )
Buoyancy ...
Structural integrity ..
Biodegradable etc.......it would make a good read .....peace
