Sealine S28, opinions and what to look for?

Pre facelift s28

IMO the older mk1 (pre-facelift) s28's only offer decent value for money IF and only If they are meticulously maintained and are in first class condition.

Lets consider two examples;
Buying a tired s28 with AD31's for around £40k, engines will have been used for well over a decade now, corrosion and fatigue will have started to take their toll, probably don't produce the 150hp anymore so are stressed everytime they leave the dock, the chances are the servicing will be a bit patchy, with a mix of DIY and professional attention to keep the costs reasonable.
Cosmetically it's going to need a bit of help, tired faded gelcote, the odd scrape and scratch to be fixed, window and port-light seals will be tired and will probably leak, the interior will have the distinctive musty/condensation smell from over a decade of use coupled with inadequate ventilation.
Chances are it will require more than just a clean, so basically, assume the boat is structurally fine, engines will be a concern, cosmetics will require funds to put right.

Lets assume prices around £40k for the tired example above.
Now add a few upgrades and essentials

Cockpit upholstery, tired PVC with a few ripped seams, now off white even when deep cleaned, around £1200 to replace but before you replace that, the reason they are probably bad would be the poor fitting and leaking canopy which could cost close to £2000 to replace, coupled with shrinking and leaking windscreen rubbers and the usual minor electrical faults, horn not working, radio not working etc, gas hose way out of date, safety gear and extinguishers all original so require replacement, so basically unless you can get a hefty discount your work is going to be cut-out fixing the faults, lets round it up to £1000 to trace and repair the misc faults, and that's before we even consider the interior.

Engine and drive service, £2000 (it will need doing unless there are recent receipts)
Interior soft furnishings and carpets can be around £1400 to replace (without replacing the foam)

So around £48k assuming there are no unexpected extras like new props etc, and you are willing to do the compounding and gel repairs yourself.
Add £1000 for surveys and £500 for additional mooring fees.

So all in approx £50k to change to an s28 with a market value when bought of £40k, albeit a much nicer one now you have done the work.

Buying a Mk2 Clean s28 of around £55k,
probably knock 10 years off the age of the first example, so has 10yr fresher engines and drives, probably Kad32's, engines well suited for the s28, not so stressed, serviced for the biggest majority of their life by VP or professional engineers although probably close to having DIY maintenance between regular servicing.
Newer interior, in all likelihood still in perfect condition as it's not had to many owners so probably no money to be spent there.
Still in regular use, cockpit still serviceable but canopies may need attention soon, reproofing would be the minimum at the moment.
Gelcote faded but not to the extent of major renovation, most things still work but again new gas hoses and safety equipment will need to be done, lets say £1000 as in example 1

Servicing, more than likely to have receipts being as it's a higher value asset, but say again £2000 to be safe, £1000 for surveys and the same £500 for additional berthing costs.

So around approx £60k for a boat that started at £55k, so IMHO better value for money.

There's going to be exceptions, older with replacement engines and upgrades etc, neglected newer!

So really you need to understand the relationship between price and value and make an offer based on a reasonable idea of the cost implications of buying the older boat, if you can only just afford the older one's, chances are you will struggle to justify the cost of doing it up even though it sounds a good idea.
 
If you have a 24fter with a KAD32 then you should by now have found out that the 170hp can at times be marginal depending on your load. If heavily loaded our S23 can take a while to climb onto the plane but once going maintains a good cruising speed of between 25 and 28 knots.

If you think about it logically then a boat that weighs more than twice as much but has less than twice the power is going to struggle onto the plane at times.

Good point, but my 24 footer goes like a rocket and is def not marginal with 170hp. Jumps up onto the plane and hits 30 knots. I take your point though and will probably have to expect lower levels of performance.
 
Thanks for the answers everyone. I'm a bit confused about the 150's being underpowered. Brochure metions 30 knots, which should provide a comfortable cruise in the low 20's and that's perfectly enough for me.

Also, didn't they used to put a pair of these AD31's in the 305/310 flybridge? Sometimes in the 130hp format. Surely that boat has got to weigh a good ton or so more.

This is actually going to be our second boat, as we are moving up from a single diesel 24 footer. Wonder if I can swap the KAD32 out of that :D

We don't have an S28, but we do have a Hardy Sewaings 305 (which is for sale!), over 30' but a similar weight to the S28. We have twin AD31P 150s. We generally cuise at 3500rpm which gives us 23knots, and we seem to average about 2.2nmpg. WOT (3900 rpm) is just about 30 knots.

Main thing performance wise with them is that without the superchargers of the KAD32, they take a bit longer to wind up and power over the hump, esp if boat fully loaded, but not an issue unless you're in a drag race.

I wouldn't worry about the comments relating to them being 'tired' unless the boat has an astronomical number of hours on it or has been neglected. Ours have proven to be extremely reliable over the 2700nm we've logged over the past four years - they've never missed a beat. They're extremely simple and robust engines, and ours at 14 years old have only minimal surface corrosion evident. Easy to DIY service if that's your thing.

PM me if you want any more info.

Also worth noting that two x 150 HP does not equate to the same thing as one x 300 HP. Additional weight and the drag of the second leg will result in a less efficient setup.

It does very much depend on the loading. If we are carrying a light load ours jumps onto the plane. Start packing the boat up for a week or two aboard plus plenty of booze and she starts to struggle over the hump and benefits from some assistance from the tabs but will still cruise along happily at over 25 knots and reach 30 knots. The difference is in time taken to get up and going.

An S28 with the little engines, loaded up with plenty of gear (and it is suprising what "gear" you pack aboard over time) will struggle to get up and over. It may be worth looking for examples with the bigegr engines. Did they fit them with AD41's for example?
 
I have owned two boats with AD31's (130hp and 150hp) and one with AD41's. Best engines I have ever had. Bit smokey when cold but brilliant. I trusted them emphatically. Better than the squeaky D4's on my last boat. We'll see about the D6's on my current boat...

Older boats tend to be underpowered compared to their modern counterparts. Engines have come a long way in the last decade in terms of their power to weight ratio. I cant say the same for their reliability though!
 
Also, I think I would prefer the AD31's to the KAD32's even if the power is marginal. I dont like the way the KAD32's scream when the SC kicks in. Makes certain rev/speed combinations unbearable.

The trick is not to sit in the SC range. You are just wasting fuel anyway as the boat is neither at displacement speed nor planing.
 
I agree, many generalisations, but some points to think about when deciding between older and new examples and the difference in value of what is in essence the same boat.

We did exactly the same thing, looked at many older s28's because of budget, most of the common disappointments we found are mentioned in example 1, it seamed like natural progression from our sealine s240 but we did eventually buy a Fairline Targa 28, so not much difference between our wish list and that of the OP.

What I tried to explain, (perhaps not too well) was the difference in price and value comparing older and newer 28's, they built them for well over a decade so there are plenty examples around.
In the examples I speak from experience, even if the prices look strange, (I'm talking real prices, not asking prices back then), in general the price always reflected the condition, although some were having a laugh and clearly had no concept of age/condition being a bearing on price, so to some extent if you wish to make the condition of an older s28 comparable to better or newer examples it could cost way too much to be worth considering.

However it is possible to do an older boat and get better value, if you find the right boat, as with our Targa 28, an old boat, in fact only hull no'18 from around 235, it was cosmetically neglected but sported a pair of brand new Kad32's and drives, replacing the twin petrol originals.

The cost of cosmetics factored into the offer made the deal worth it, coupled with a realistic owner, had we purchased an older boat requiring more than cosmetics then it would not have been worth it.

At the time I asked the same questions of the forum, and struggled when choosing an older boat over a new example, but then we didn't have the choice, Targa 28/29's were only made for six years, between 1994 and 2000, so nice examples were harder to find and some work was inevitable.

I found that in certain sea conditions (uncomfortable head sea), when you are sort of planning at about 14knts with the tabs fully down, you sit in the SC range. With my smaller boats I always seemed to be struggling against a force 4 chop.

What works for me is to go a bit beyond the SC range then back off, very gently, until you are doing about 16kts and 2600rpm with tabs fully down and both outdrives trimmed to -4. This keeps me semi-planing through most conditions that I would want to go out in. If it's still uncomfortable, best to divert to the nearest waterside pub and try again another day :)
 
PMSL!

I completely agree about that, 100%, totally and without doubt. Nasty thing.
But, I do prefer it to the hard, wet ride and sloppy low speed handling of it's big sister.
That's how bad I think the S28 is.

Blimey, you think an S28 is bad, try a Bayliner 2855 upwind in a moderate chop :eek:
The hull feels quite solid, but you might lose some teeth along the way.
 
I've had 5 great years with ours. I wanted a t30 but the price difference at the time was 30k. A few years ago i had a look at a t30 and was so dissapointed with lack of space / storage and features you get in an s28. Weve had no regrets. Theres plenty to choose from.
I think approx 440 were made against approx 90 of the fairline t29's.
There both good. Buy what your comfortable with.
I like t29 bathing platform but prefer s28 accomdation and flat cockpit floor.
Handling wise both are excellent and better than similar american boats. I dont believe there is a lot to choose really between them.
good luck
 
Hi

Some very interesting comments about the S28. Now, when I was looking around to buy one the only real advice that I remembered was from the Sealine dealer at Brixham regarding the engines, he said the 31's were OK but if you went on a KAD32 S28 you would not go back to the 31's, apart from if you are on a river.

I have had my S28 since new in 2002, some 1200+ hours later and I still love it, never let me down (until now) and believe me I am out there in most conditions. I do not seem to have the handling problems that have been mentioned on some previous posts.

If you do your own servicing you maybe need to look in a Fairline 29/30 then the S28, both KAD 32's, you make your own mind up which engines you would want to work on!! I know exactly where I would be going! I'm not saying the T29/30 is a bad boat by the way, just access problems.

I know of 5 people that after going out on my S28 have now bought their own, maybe I should have been on commission from Sealine!

Which ever way you go please let us know which boat you bought and don't forget the pictures!!
