questions. how old are the cracks. are they stable or 'growing' what alloy is it. are welds of chine flat/bottom plate on both sides of plate. if...
I agree with kapnD and add that the 'cat like' bottom will also be more maintenance (access, paint, repairs, etc) than a simple V bottom.
A drawing and specs of the boat might help. Is it a 70' x 19' aluminum passenger vessel? I don't think the angle x drive will work.. One...
You are correct but the 'topic' and his first post don't quite match up unless he meant 'for' instead of 'from'.... which I assumed. How can we...
what size of boat is it???? If the stability book is current (you will have to do a lightship survey) you may be able to use it. If not, another...
Cheerfully isolated and private..... Rather like Alcatraz.... or St Helena, or Elba,...... if you are a Parisite.
Take a look at Armstrong Nautical in Florida (There may be an agent or similar fabricator in the UK). I was involved with a Bertram 26 (classic...
check the transom, starboard side and see if there is a HIN
I could be way off base here but if it was Roman they would use Latin.... which is the root of several Romance languages - French, Spanish,...
Displacement Length ratio in imperial is: D/(0.01 x LWL)^3 D = long tons (2240#) LWL = feet as noted in Gerr's book pg 13, and also several...
I did a 'quick' review and (a) That 50% increase (4mm to 6mm) in plate thickness probably did the trick re the weight matter your...
what RPM is the engine rated.
Any photos or drawings of the boat that you can post here would help. If a displacement hull is it a power boat, sailboat, chines, round, etc ...?????
a 50% power increase is quite a bit. You may not need it, or be able to use it. what is the reduction ratio, vessel displacement, LWL, etc?
I agree with Tansl. I watched the video and was not impressed. It is essentially a case of Gi-Go (garbage in -garbage out): it would certainly...
Text books & organizations (IMO, etc) can be excellent but be cautious about magazines. There was one published in a magazine about a year ago...
Other features: The 'forefoot' is deeper than the rest of the hull so beaching is compromised. Hull is assembled using weld, glue, and fasteners....
you are describing 'broaching' or 'broaching to'. At slow speed the boat can 'spin out' and at high speed it can spin, roll, and eject the people...
Closing the gap might work if the rudder was kept 'straight' . I saw one fouling case where the skipper turned last minute to avoid the trap and...
That is for an aircraft and air is a lot less dense than water. It could work but a lobster trap rope could still foul it. This is one reason (the...
