"All designs would be more secure anchored-from the stern"

Why would numerous boat manufacturers put anchor lockers in the bow?
 
I think they are referring exclusively to snailbloats. I would seriously doubt this technique would apply to power boat hull designs.
 
If this is true just think of what could have happend. Hind site is 20/20.

All four would be alive today if they had merely cut the anchor rope and gone home without it.

No were in that whole artcle is there mention of a powerboat The only thing that is talked about is a sailboat I would also agree that a sailboats design would be completely different from a powerboat But hey what do I know about sailboats never been on one and don't intend on starting now
 
I can think of several reasons not to anchor off the stern. The wind and tide will turn the boat so that it faces into the wind or tide. I would not like to be anchored and have the wind pushing the waves against my transom. The pressure of the wind ot tide is less on the pointy end rather than the flat end. That would mean a smaller anchor is needed to hold a boat in place anchored from the bow. The bow tends to be higher than the the transom less of a chance of water coming over it. Finally if you have to move your boat to pull up the anchor, it is a lot easier to have the rode away from the propeller, especially when it is chain.
 
With my first boat (a 19 footer), I would sometimes anchor from the stern but only in dead calm anchorage areas. Mainly to get a breeze into the cockpit. With this boat, there are times I wish I could anchor from the stern b/c heaven knows, on those dog days with little wind, it's nice to have the breeze hitting where your sitting. I suppose I could do it but way too lazy to lug the anchor from the bow to the stern.
 
"Power boats are often better than sailing yachts. However, boats with a high bow and a large structure forward can do poorly. All designs would be more secure anchored-from the stern."

Jes sayin'......and quotin'.

I'll admit, I got tired of reading the whole thing. Reading comprehension is not my strong suit and I have an extremely short attention span.

What was the question again...?

Yeah it gave me a headache too!. With my limited boating experience, I think I'll stick with anchoring from the bow. Just makes more sense to me. (I don't like arrows and drawings)
 
The article refers specifically to certain types of blowbote hulls.
I can't comment on that as I know nothing about their hull designs (and don't want to!).
He did not recommend this technique for powerboats, and stern anchoring in heavy weather is nothing but suicide for a powerboat hull.
 
Gotta think about what your boat does when at anchor. Any current or breeze will tend to have the boat pivot on its anchor chain/rope. Powerboats would have an issue with the chain/rope getting caught up in the prop where as a sailboat would not.

All my years in the Navy, I never saw a ship with an anchor anywhere but in the bow...for that very reason.

My 19' Regal didn't have an anchor locker either. Kept the anchor and rode in the ski locker btwn the front seats.
 
Anchoring off the stern might be a hazzard in choppy seas. You wouldn't want to get the Honda generator wet - right??:grin:
 
I for one would agree with the Jordans when it comes to modern high aspect ratio sloops with shallow draft keels and and unskedged spade rudders. These boats "Sail" on their anchors and must be settled with the use of a riding sail to calm them down in high winds. The older or say more traditional full keel sloops etc. do much better and are more stable on the hook in rough conditions. That said, the danger of anchoring off the stern is mentioned several times in the article but not caught and highlighered in this discussion amonst we power boaters is the subtle statement to the effect that "There is some danger from boarding seas." Meaning the danger of being pooped and down flooding when anchored from the stern. This is a fact bigger than the mention. The whole discussion is about heavy weather anchoring and for my money I'll avoid stern anchoring in all cases except a quick lunch hook arrangement or setting stern anchors as a secondary in a fore and aft set up in tight quarters to avoid any swing on current or wind.

Power boats are made to take their weather on the bow, period. Wide, low slung, sterns presented to large waves and the lack of any bridge decking on most power boats is a prescription for down flooding in bad weather and mounting seas.

The Drouge maufactuers would tell us that power boats biggest risk is from sliding down a wave stern first and pitch poling. Thus they make a drouge to be towed in a following sea at 2-3 knots forward to keep the stern square to the seas.

I hear this ancoring from the stern but I aint buying it with my boat nor the souls aboard until I talk to some survivors.

I carry a 14' cargo net type drouge for a storm sea anchor, and a lot of good sense.
 
We discussed this a little back here:

I like the guy's free-body-diagrams on how a boat rotates to start sailing upwind and back and forth on the anchor. However, I'm not real crazy about him calling it "unstable". It would be like calling a grandfather clock's pendulum unstable and it is not. The boat will not sail upwind past a certain point as the forces making it sail on the anchor decrease the further upwind on the anchor you get... that's why you start sailing the other direction. That's not a feature of instability. It's just a feature of sucking because you don't want to swing like a pendulum.

The issue is the swinging produces a lot more force on the anchor. His whole point, and a good one, is that putting the anchor on the stern makes a boat now want to orient itself so the airflow will be such to NOT start the sailing process. That's all good... but a bridal on the front of the boat may be enough to prevent it as well. I would guess the bridal on the front would become less effective is very strong winds but that would depend how wide the boat is as well...

It was an interesting discussion but not really practical for power boats and for preventing the sailing at anchor problem, a bridal on the front will probably solve most issues. Not sure about a hurricane though... never anchored out in one.

It is a rude awakening how a boat does not want to have the "pointy end" into the wind but prefers to have the stern into the wind. Being caught one time in a squall from hell with 60+ knot winds was a real eye-opener for me as the rudders did not have enough hydrodynamic force to keep the boat pointed into the wind while moving at displacement hull speeds (less than 10 knots). The books like "Chapmans" forget to mention that little detail. The force of the wind on the topsides, especially for a bridge boat, can orient the boat completely wrong just like surfing down a big wave... a drogue would give more control to keep the boat pointed into the wind even if you are on a flat river in a raging afternoon squall... My 2 cents.
