That would be fantastic - my email is trevor@privateambulance.plus.com I need something more satisfying to spend money on, as I've just forked out nearly £1500 on outdrive work and antifouling!

sorry to bump an old topic, but I was wondering if Peter Stephenson had any pictures of his 25's enclosed wheelhouse, as it is something I am keen to do on mine. (or anyone else with an enclosed wheelhouse!) Regards Trevor Fox

To Vicsims (no.2196) Hi Vic ,do you still have your Hardy 25 with Johnson 60 ob,if so what prop size do you run and have you tried fitting engine mount wedges or trim tabs? I have just bought a Hardy 25 with Johnson 60,I know it will use a lot of fuel but the maintainance is so simple compared to the twin diesel cruiser I have just sold, no more squeezing into the enginroom for winterising,just change the gear oil and grease and oil a few pivot points whilst she is on the trailer. Regarding fitting a diesel to an outboard boat, it must be better to sell the boat you have and buy one with the engine you prefer,the seller should know the perfomance and economy figures of that boat. Bear in mind that if it has an outdrive they seem to need more maintainance than the engines to which they are attatched. This observation comes from many years of boating with outdrive powered boats and I have now returned to a simpler method of propulsion.May have to change to a Honda 90 if I cannot stand the noise though.Regards, David.

Hi I also am looking at a 25 and converting from Volvo to Mercruiser. Does anyone know the limits of weight of an engine on the 25. I would like to go for the 150 mercruiser D-Tronic deisel. Anyone ever imported an engine from America?

Could anyone give me some information on the Hardy 25 that I have now owned for 4 years. It is powered by a Johnson 60 h.p. 2stroke giving me a max speed of 11 knots.Cruising speed is 6 to 7 knots. It goes without saying that the fuel used is considerable. Would it be possible to fit a deisel outdrive or would the best option be to part ex for one with a deisel engine already installed. I have had great sailing times on the broads and around Lowestoft and Yarmouth but would like to increase the speed and decrease the fuel costs. I await your comments. Thanks Vic

Hello Raymond, I'm sorry I can't help with your enquiry in a definite way but I think if I was going to build a trailer for my 25 I would be looking to place the wheels slightly aft of the companionway from the wheelhouse to accommodation. My boat has a large stainless steel water tank in the forepeak. If you're making the trailer yourself suggest you experiment with the axle positions with brackets and clamps before making the final weld up. So welcome to the club. I've had some chat with Charlie Stitt and I think you've bought a good boat. Did you sail it over? Best wishes Peter Stephenson (Co Durham)

The Hardy25 owned by Charlie Stitt, Pleiades, has now been bought by me and taken back to Scotland, Findhorn on the Moray Coast. I am about to contruct a yard trailer for winter storage use and my query is:- I propose a 4 wheel trailer and query the position of the twin axle to the boat length to give an equal weight distribution from the tow hitch and balance when standing with jockey wheel down. Can anyone advise on this it would be much appreciated.(I have just submitted my membership application).

Does anyone know the original pitch, diameter of the prop fitted to a Hardy 25 with a 150Hp Volvo 6 cylinder. My boat smokes a lot initially after moving the morse then settles down. I'm just curious as to whether the engine is being overloaded initially.

I have an original brochure that came with my 1983 Hardy 25. It's only one page, but has all the spec (I think). Let me know your address, and I'll post a copy. Bob Smith (Eurypyga)

Cairns, I think your best course of action is to contact Hardy Marine Tel 1692 408700 and get the true particulars straight from the horses mouth. Other 25 owners like myself would appreciate you posting the findings on this forum. Charlie.

I doubt that the waterline lenght of a 25 is 25', perhaps 22', so might be only 6.25Kn!. But this is the ''natural or hull speed'' for a displacement boat, and is the most economical speed requiring the smallest engine and with very little wash. If you increase the power the boat will certainly go faster, albeit at the cost of much higher fuel consumption and with a lot more wash. The limit to speed is engine power and also the speed where there is sufficient hull in the water to maintain stability, steerage and safety (and common sense) for that hull shape, which in a boat designed for this purpose would be of semi displacement design or planing.

Thanks John but don't understand this. Boat did over 20 knots with previous engine! Not 6.7. Am I missing something? Cairns

Is there a 'hull speed' for a Hardy 25? I am in the process of having a Volvo D3 fitted. Cairns Langlands

The theoretical hull speed (knots) can be calculated from:- Max hull speed = 1.34 X square root (waterline length ft) e.g. for a 25 ft waterline length = 1.34 X (5) = 6.7Kn Of course you need a clean bottom to achieve this and there may be other factors slowing the boat down

Yes Peter I am on broadband. You will miss the trimtabs if they are not working, there is an in-line fuse below the dash, worth checking. I have never dried out, always haul out on a trailer but I guess it would be no different to the pilot, something about a pilot drying out on this forum. Best of luck whatever you decide to do. Charlie.

Hello Charlie, I'll take the camera over with me next time I'm on the boat and mail the pictures to you. Are you on broadband? By the way it looks as if the trim tabs may be stuck. Although its restricting the speed I may have to put up with it until the spring when it comes out or try and persuade my son to dive. Can your Hardy ''dry out'' and if so what method would you suggest? Peter

Peter I have no experience of your type of engine but I would be surprised if it did not have about 4000 rpm to offer. My Mercruiser revs at 4300 max and cruises at 3400 rpm, at 2200 revs I would also get about 7 kts, its the few hundred revs above 3000 that makes all the difference in speed. It is also around 3000 revs that I would start lifting the tabs, a little at a time, until the performance is at its best. It is only by having plenty of practice that you will get to know your boats best trim by sighting where the spray rises forward, remember that if the bow is trimmed down too much you will get oversteer and with a following sea that can cause problems but you will soon get the feel of it and in a few weeks time you will have the confidence to sit back and relax. Regards, Charlie.

Hello Charlie. Sorry for not replying sooner however the deed has been done and the boat moved to Hartlepool on the 26th May where we spent some time on her engine, service, new impellor and alternator. Moving her for the first time from the crane to the pontoon was a bit of a shock but we tried her around the marina on Saturday before taking off for Sunderland in the afternoon. Noting your comments re performance although the engine ran well we couldn't get her to plane we were running at 2200rpm. The forward water tank holds around 50gals with a similar anchor chain as your boat. Obviously we are doing something wrong here as we made around 7 kts in this configuration. Apart from that the boat handles very well and can turn around its own axis, with practice and use it will be extremely effective. The enclosed wheelhouse is great considering that Saturday was fairly cool with a north wind we were comfortable. I can recommend it. If you want pictures of the aft panel and doors give me a shout. Best wishes, Peter

Hi Peter, You are lucky to have enclosed wheelhouse, if I keep my 25 then I shall look at enclosing the wheelhouse at the end of the season. I had a new Mercruiser 120 hp TD fitted a month ago, at maximum revs with two adults on board and with perfect sea conditions, I got 21.5 kts and at the recommended 3/4 throttle I got 13.7 kts. I found her to be very comfortable at this cruising speed and found her to be the best with leg trimmed full down with tabs about 2/3's back up. She also behaved rather well at this set up in a bit of a chop. My boat carries 120 lt FW in a tank right ford and 35 mtr of anchor chain in well ford. New Mercruiser much lighter than the old Volve which it replaced.It will take a little time for you to get the feel of the 25 but once you do you will have great boating. Cheers, Charlie

Hello Charlie, Thanks for you're help. Since posting my original enquiry I've received the following from Andrew Rosthorn of Sealand Boat Deliveries: ''The exact weight of a Hardy 25 will not be more than 2500 kg. The designed displacement was 2 tonnes. Hardy 25 motorcruiser Length overall 26ft 3in 8.00m Beam 9ft 0in 2.74m Draught 2ft 5in 0.736m Displacement [weight] 2000kg Height above waterline 7ft 10in 2.41m Transport height 10ft 3in 3.12m designed by Colin Mudie and Hardy Marine Ltd., North Walsham, Norfolk. NR28 0AN'' I'll work on 3 tonnes to be safe. My boat has been surveyed at 27 feet 3 inches O/A and has an enclosed wheelhouse with a slightly extended roof unlike the other Hardy 25s I've looked at. Do you think that this was a bespoke boat? The workmanship and fit all look original. Estimates for speed are around 18 knots does this compare with your 130hp Volvo? Thanks once again for your help. Peter Stephenson

I have a 25 which I was told, when I bought it fitted with a 130hp volvo,that its weight was 2.5 tons.To be on the safe side however I worked on a gross weight of 3 tons.

I've recently bought a Hardy 25 and am arranging transport to the NE of England. Could any of your 25 owners give an estimate of gross weight for this boat it is powered by a 130hp BMW inboard? My best guess would be around 3 tonnes is this about right? Thanks Peter Stephenson
