We've got Fisher who has an Ali version of the 16ft Sea Nymph and Olfart reckons 14'6 Sea Nymph will handle rough weather.
I've heard from other people too that Sea Nymphs do ride real well in heavier conditions.
Anybody can share their experience and give their input please???
thanks

Ron blue.. I have owned a number of glass Sea Nymphs.. 2 x 14.6..  1 x16.. 1 x 17.6 and loved them all.. My present ALI boat was purchased to suit this area for beach launching and sea keeping and handling..  also changing the motor to 4 stroke for fuel economy...
Rather than go round and round and round in circles as you are.. write down what you want in a boat for the area you will be fishing in..  size, motor, electronics you want, and whether new or second hand relative to your budget.. these thing will determine what you can afford and get...
Then go out for a ride in it to see if you like it... how the motor runs and if all the gear works...
Good tidy second hand boat with the newest motor you can afford within your budget...that has a service record provided...  Take someone with you that knows what to look for..

Ron, you do seem to be spinning in ever decreasing circles....

One of these would be cool, three size options and you can fit out the hull however yuo want.

And it will always be a compromise... between ALL of them..  Firstly, Don is right on the button.. a 14.6 Sea Nymph must have a 70hp motor to use it gull wing attributes best..
Ron, you seem obsessed with this sea handling ability..
My ALI boat rode like a brick crap house with the 40hp on the back because that engine was too light and with 2 big guys up front it was nose heavy.. but I saw past that having owned many boats.. simply put more weight in the back with a 4 stroke motor...and now I have a great resolution.. power to push it and weight to balance the boat , even with 3 folks now..  One forum member said it was the"best ali boat in its size he had ever been on" and we were in 1.5 metre seas just running over the top of them...
Do the paper trick and you will see that new is not going to be affordable so next best answer is to find as Brook has mentioned, a great boat (thats a compromise) you will be happy with..
I assure you, you will get a different answer from every boat owner saying there's is the best...

fair enough.... where will you be fishing...??  what area...??

What made the Sea Nymph 14'6 good was the deep vee and gull wings.

I bought an Allicraft 16 foot in 1991 that had the same sort of hull, but was too light with a 2mm hull.

The best hull for the rough was the ultra heavy Morgan 6.3 metre, very deep vee and big gull wings, when the Morgan landed the waves got out of the way, but at 2 nm per gallon you needed deep pockets. (200 2 stroke Merc)

nice pic!!
pretty close to the action!

Ronblue, will you be beach launching?

Is anyone doing the type of boating you're planning to do in the area? What are they using? I must admit your posts have confused me a bit but maybe that's just me. 

Beach launching, exposed isolated area, perhaps I'd be thinking pontoon or IRB. Reason being if something goes wrong and you take a wave on board, the stability compared to a standard hull will give you a better chance of self recovery. Might not give you the best speed or softest ride but when the chips are down well....

Brook makes a good point. Quite often the skipper's ability and experience level is the Achilles heel or weakest point. We were recently called to a vessel with a skipper of a 5m fibreglass runabout who was very concerned that the conditions were going to overcome his vessel. It was a bit lumpy (a little over our cabin roof I suppose) with a confused chop on top. The waves were breaking up over his foredeck and the odd one was probably washing up over the top and into his lap.

As soon as we were on scene and looking at it, it wasn't riding right. Then we did a head count, we were one short and asked the question if someone was up forw'd in the cuddy? Yes they were. We suggested they move back a bit to get the weight out of the bow, and then try to increase the speed a little from 3 knots to 5. The improvement was vast and all we had to do was shadow them home. It was a classic example of a fairly capable boat being well and truly "held back" by the skipper. His lack of experience resulted in quite a high degree the of stress / panic when faced with the conditions and as a result he developed a narrow view of options. A similar sized boat in the area had 3 guys quite relaxed chugging along! The main difference was the experience level of the skipper / crew.
