I assume you have read a bit about Sealine already on the forum. Some people love em, some people loath em - but they are one of the best mass producers of family orientated cruising boats around. They can pack a lot in to a little space and often you end up wandering where there competitiors lost all the volume form their boats.
I like most of what Sealine do. I will say that first because the F33 is not one of my personal favourites. Is it a bad boat? No, infact there are hundreds of very happy owners who use them, enjoy them and clock up loads of miles going here there and everywhere. They will be along in a minute I imagine.
However, as with most things, its a good boat if you are aware of its limitations and use it accordingly. I personally dont think any small flybridge really works perfectly, they all tend to be a bit top heavy but the F33 does seem to be worse than most. Its light, gets blown quite a bit and can feel a tad unstable if pushed hard. but the point is, the boat isnt designed to be pushed hard and if you keep it within its limits then they are fine craft.
however, one of your requirements was a good all weather boat, one that you would feel safe going out in a F6 with the accompanying seas. If that really is the case, then an F33 really isnt for you. In fact, I dont think many FB boats this size would suit. I would still reccomend any of the boats on the list I posted the other day, erring perhaps to the Aquastar if roughty toughty handling really is a must have.
One more thing, I thought you had a mobility issue reagarding steep and or narrow access? F33 FB is probably not for you anyway, even if the rough weather bit isnt really important.
As Whitelighter says, this boat does not match your original post but then sub 30' that will go through anything is a tough order to fill even if you put a professional at the wheel.
Boating is very personnel and each boats layout will be of varying interest to individuals.
If mobility is an issue then you need something that is easy to board so probably something with a Transom gate, look through the rest of the boat for doorway widths, access to the toilet, even getting onto the bed. All these things can and probably will be very different to doing the same at home when on a 30' boat. dependent on how severe the mobility issues are then side deck widths may or may not be an issue, but if you want to walk round the boat you may need to look at a Botania Targa or the like.
Strangely, My SWMBO is restricted a lot in mobility, we do 70% of our boating on the Norfolk Broads and 30% at sea.
Our boat should be a displacement or semi displacement hull with a good length of keel, to give control on the rivers. Have low headroom to go under the bridges, so a sedan. Preferably a single diesel engine around 120 hp, so that it runs with some load on the river. and should be as close to single level throughout as possible.
We have a Sealine 310 Flybridge as we love the Flybridge and the views we get over the banks, unfortunately SWMBO can no longer get up the ladder so having learned our lesson we are going to change our boat.
We are buying a Sealine 330/F33 as it is the only boat under 35' we can find with stairs to the flybridge that SWMBO can climb, most we have looked at don't even have a transom door and apart from that we like the boat.
Wouldn't argue with a thing Whitelighter has said but you will find that one thing is more important to you than everything else. Make sure you tick that box then see what's left of your selection, fill in as many of the boxes you started with as you can to find the most suitable and then if it is your first boat go and buy that twin 500hp sportscruiser that you liked the look of.
I have not got a Sealine but I really like th F33/34. I think Sealine have done a great job with the packaging/styling etc. Yes the flybridge is quite small, but adequate.
I think it is well made, having crawled over a couple of 10/12 year old examples, which look and feel fantastic.
Why don't I have one? We are currently parked on the R severn, and the flybridge, while great for viewing scenery, would be very hard work with bridges etc. Therefore our sports cruiser suits us best at the moment.
If and when we are parked on the coast, it will be a flybridge for me.
to do a lot of training on them, they are great family cruiser for gentle cruising, wind and sea state can make them a lively ride , that is not for everyone.
Saying that, I have had them out in F6/7 with a 2 to 3 m wave hight, you just helm from inside , it can feel like you are in a washing machine and you do have to work the controls a bit, but they can and do handle the rough stuff.
What is your budget?
For something a bit different and quite rare (only 14 built reportedly) could this be worth a look, plenty of space, flybridge style etc, not sure of the practicality though with disabilities.
...It's a shame the model isn't on shafts as it would feel a lot more solid in the water.
I believe an old customer of mine used to refer to the Sealine F33 moored next to him on the Hamble as the Eileen F33 whenever it was underway. Can't possibly think why?
That said, it packs a lot in and "parked" up in the marina it looks pretty stylish.
