Hull shape how aware are you ?

[Deleted User YDKXO]

I hate to say this but you might just be proving Portofina correct. I.e. Get the right hull and modify everything else to suit after all the hull is the only thing you can't change

Whats the right hull? Every hull, at least cruising boat hulls, is a compromise, usually a compromise between accommodation and head sea performance. The fact is that most of us go cruising with SWMBOs and family and they don't give a toss about deadrise so for them the right hull has maximum accommodation. I would argue that the right hull for a cruising boat is any hull that gets you home safely. And one thing we haven't talked about is weight and weight distribution. For me I like the feeling of helming a boat which is heavy and carries its weight low down and I would trade that for a sharper deadrise hull any day

Ok so now I'm going to defend Portofino, I think all he says is decide what kind of ride you want, know the science and you will be able to determine if a particular hull will meet your criteria

I usually agree with much of what you say, including my own preference for a heavier feeling boat that tracks predictably and doesn't bob up and down over the slightest waves. However, despite my other half's preference for an upmarket floating apartment, there's no way we'd be going anywhere in the choppy stuff if she didn't believe the boat was safe. Such things as a slamming hull or excessive rolling would most likely have her running for cover and turning all sorts of unusual colours, and all thoughts of the swish surroundings would have long vanished.
As it happens, we are currently looking at replacing our existing heavy & safe-feeling Trader with something a little larger, and with stabs, and the choice of hull versus accommodation has proven to be the most challenging consideration of the lot. But, in our case at least, because of our longer distance type of boating where we can't always guarantee ideal conditions, the choice of hull has to come first every time. Just a shame we can't find that hull with a suitable interior, though!

Well I'm lucky (if thats the right word!) because my SWMBO is usually braver/more stupid than I am so I'd never have a problem persuading her to go to sea in anything providing it had a big galley and loads of space for her clothes/shoes. But I think you've proved my point. You can't find a boat that meets both your accommodation and cruising needs so eventually you're going to have to compromise. The hull design can never be the sole consideration when choosing a cruising boat. Not if you want to stay married that is

I think your first point may well be correct. And even though I wouldn't disagree that just one aspect, such as what type of hull, is likely to be the sole consideration, if that one aspect happens to be an over-riding priority then the compromise will be irrelevant. So, far from proving your point it surely does the total opposite? Thanks for the tip, though, maybe it's the married bit I should be looking at more closely.

 

[Bouba]

So it's come down to one word, is the hull 'the' consideration or 'a' consideration. What's more worrying is all these forumites under their wife's thumb. It used to be iron men in wooden boats, now its jelly men in plastic boats if their wives let them
I have to sign off now, the wife's calling

The problem is that without the married bit there's no boat

You should have anticipated this problem earlier, and salted enough away for just such an occasion. It's times like this that I wish I practised what I preach.

Tell me how you can salt away money legally without declaring it in the divorce court and I'm all ears

"the right hull "

What is it that's a good Q ?

I would say its one ( in your budget / size range ) that enables you to go out when you please ,keeping everybody happy / comfortable - in the widest variety of sea states for as Long as you please .,as as fast as you please .
Without shaking your boat or yourself to bits .

Turning it arround
Wrong hull is whereby you don,t go out ,or if you do it's a miserable day , essentially too rough .If a planing boat it's banging away so much ,you end slowing right down -- makes it worse ,rolling and in it -that sea state -longer -extending the misery .

Your boating dare is say it" enjoyment " is restricted / compromised . ---- by the hull form

Of course as others have said in the typical 50 FB segment ,esp perhaps with a family and some nice beaches or other onshore activities ,a dominant Mrs ,then in this scenario ,cos they stay in -hull form is low on the list ,it can,t compete with the holiday home / floating appt .

It should not either .

Kinda brings it back to how you use your boat .
There's absolutely nothing wrong with that .

Accept as OG said this subject -it's divided opinion certainly !

" are you bothered about hull form " and the provocative deliberately chosen Opening sound bite "absolutely nothing will influence your Enjoyment more than hull form "

The word "enjoyment " re hull form ,running off at a tangent by some -how ever that's forums .

But as allready stated in previous posts folks do regret the ride after purchase and change ---at all levels .

Here's some more tech stuff - I think it well balanced - just sub the "sport fisher " - for a suitable eu word . basic principles apply .

In my view Deleted User ,it's not actually ALL about the deadrise per se .which is the angle @ the stern .
You can see that Obviousley walking around a ship yard ,it's the hull angle where the water hits pounds the hull somewhere between the stern and bow .
You alter that few M contact area by trim ,and wieght distribution .
Hanging stuff off the stern will bring that back ,tank position and levels etc, to a less sharp part .Shoving the engines back too..But then shoving the superstructure fwd will even that up balance wise .


So by looking under the rear 1/3 rd ish - that's the crucial area to examin .iMHO .

So it's how fast it sharpens up from the deadrise @ the stren to the finer pointy bow .


http://www.sportfishingmag.com/boats/perfect-boat-hull


Weight distribution is important , to stop it riding bow high and pushing the contact area to sternwards to where the hull is flatter . You want the deepest part ie the more fwd section of the hull to be for want of a better word the "receiver " of the wave .

All this can be bodged out with trim tabs ,which create drag and burn fuel ,slow you down .If you have to use then in a flat /slight sea -- hmmm -- not deal weight distribution .You have a " wrong hull " IMHO

Those who are in the hull camp need to test drive a boat first ideally in the conditions that think you will be most happy with .

Those not in the hull form mwho kinda ,know hull shape is something that the designer / bulder --- must know what they are doing - ,and they are real fussey about the FB griddle " will it do the prawns right "

Need not test drive .Just sign a check -depo @ the show .

Sorry about posting the link -is it ok MapishM ?
The less techniical minded can go off and source the finer points of croc skin to inlay in the saloon tables - was the croc farmed and if so humanely killed ? .

I've already said that I for one am now considering my options on this matter -
just so long as she doesn't find out - then I'm for it!

Wow, I'm flattered.
I must have missed my official appointment as judge of what links are ok or not...?

It's quite surprising to me at least, how often I read of people rejecting a boat because the cabinetry is the wrong shade of wood. Also how good cabinetry is taken as a sign that the whole boat is quality. The same seems to be true with motor homes.

Motorhomes appear to be trimmed with some kind of compressed paper from what I have seen! Dormobile being one of the few exceptions. (Yes, I know, there are a few more, but not many!!)

Even more to my point. People aren't even really judging cabinetry. Life is just a veneer

Forums eh?!!!!!

I bought a Ferretti and modified both helm seats

Haha cheek in tongue reply of the week!

 

[petem]

I think most people tend to go by what the reviews say and also derive some reassurance from who built the boat and designed the hull. For example, the Fairline / Olesinski partnership churned out safe and predictable hulls* for many years and it's pretty nonsensical to suggest that the average punter at a boat show will be able to infer anything further by actually seeing the hull forms in the flesh.

Talking of FL, it will be interesting to see how the Vripack naval architecture will work for FL. I guess we'll only know when the 63 is launched.

* Although I'm not convinced that the IPS boats were quite as successful in all cases as this is apparently not the traditional Olesinski sweet spot.

Not tongue in cheek at all. Ferrettis are great boats but they do have a blind spot over helm seats. I am happy to buy Ferrettis for their other attributes and improve their weaknesses where I can which is why on my current boat I had both upper and lower helm seats modified to suit me better

You can't blame them anyway, 'cause you are not following the instructions of their user manual.
Which as I recall, at the "while under way" chapter, says something along the lines of sit back, enjoy your drink, let the masseuse take care of yourself and the captain of the boat handling...
