SeaSurveys Marine Surveyors

To help you explore this site quickly & easily click here to open up the quick navigation page for direct access to a host of useful pages of information.Windward_workWe are professional marine surveyors & shipwright based close to Dorchester in Dorset. We cover an area from: Plymouth to Littlehampton on the South Coast and the Bristol channel. We carry full public & professional liability insurance to ensure customer satisfaction and peace of mind. We are approved and authorised by the MCA & Seafish to carry out surveys/inspections on New-Build & existing Fishing vessels.

1 The first step is to give us a call so we can talk about any concerns you have prior to commissioning a survey. Without committing a penny you can find out what we know about a particular class of vessel. It is possible we may have surveyed the vessel before. You have nothing to lose and everything to gain by contacting us.

2 Having confidence in your surveyor is very important. Your life may well depend on their knowledge. Once you talk to us you will realise we are very experienced and take great care in all we do. Clients are welcome to observe and and ask questions if they are in attendance during a survey.

3 There is a vast amount of information in the site of potential interest to new and existing boat owners. To help you explore the site quickly we have included a sitemap. We hope you find the information useful.


Thinking of buying a boat...

then read this page first. Full of tips if this is the first time you have bought a boat & engaged a surveyor. Then read this page about what a surveyor might need to understand. Presently for sale Tomahawk etc. More info.


5 common problems encountered on surveys.

This might surprise you when you see what they are. click to open


Seacocks & Pipework: One of the most common things found are gate valves that fail on test. Try fully closing & fully opening a gate valve, but moderately tight. When they are on their last legs you'll find that the quickthread that operates the "gate" fails with corrosion and you are left with a valve that either you cannot open or you cannot close. Both serious problems. Pipework hardens with age & temperature, in some cases to the extent it becomes brittle & totally inflexible & is at risk of fracture. The clips will not squeeze the hose onto the pipe stubs properly & in some cases the rigid pipework starts to strain the skin fittings.



Fuel & Water lines: One area I often come across is a rubber water hose, exhaust or fuel hose partially rubbed through on an engine casting, or even an exhaust manifold.. This can be disastrous but so easy to prevent....if you know where to look. Check where pipes disappear between alternators and engine, over engine mountings, close to exhausts & drive belts. In this photo is an exhaust hose, a fuel line & engine control all rubbing a seacock.



Worn boom & mast base castings: I often see problems where stainless steel shackles have been used for attaching mainsheet blocks & kicking strap cshackle_pin_wearconnections to the soft alloy boom or mast base castings. These hard shackle pins wear the alloy very badly and then you can see an accident that has not yet happened, but will sooner or later. Prevention is far less expensive than cure. Use a large shackle pin as this has more surface area & look for all areas where this can occur. It is also problem where stainless guardlines pass through alloy stanchion tops.



Electric bilge pump pipework: The impeller type of electric bilge pump has no valves fitted whatsoever and so many owners fit them not realising that if they do not loop the exit pipe as high as possible, the when the boat heels over, this puts the outlet beneath the waterline & the bilges will flood. So often not aware of what is happening because an automatic pump will pump the water out again. Until one day the pump does not work and then what was designed to save you....sinks you.

Stemhead fittings: Most often on GRP vessels these will be stainless steel. The usual design is a central web with a few drillings, one for the forestay attachment. So often distorted_stemhaedyou cannot see the drilling because it is obscured by the forestay or furling gear attachment fork. On close inspection you will sometimes see that the drilling is distorted by its proximity to the edge of the web, even in some cases with such a narrow bridge of metal remaining that it is unsafe for the security of the forestay & mast. Look at the distortion directly above the clevis pin.



Make use of your eyes: it is surprising how much can be seen if you know where to look. In my experience, it is not the major things that lead to disaster, but the things that cost very little or in some cases, nothing to rectify but if not seen, lead to mast failure, engine failure ,flooding , injury and even loss of the boat.

Mid Winter and all is quiet....

Here in the South, the winter has not really bitten that badly yet. There have been no major memorable gales & the temperatures have not dipped as much as some years although there have been some minus temperatures that could have caused some frost damage. The most likely areas for damage are seacocks where the seacock was left closed (vessels ashore) & water has frozen in the seacock causing a split which cannot aleays be seen before launching. Fresh water systems including calorifiers, exhaust system where antifreeze was not run through irrespective of whether fresh or seawater cooled.blown_over
Other obvious areas of winter related deterioration include wnid damaged covers , weathered varnish on the outside & mildew on the inside. This mildew can normally be removed with a weak bleach solution & will prevent quick return but if left untreated too long can cause non removable dark spots on varnish & PVC linings .
No repeat of this type of weather damage so far this winter.

So far as surveys & repairs go, the Winter does make some difficult working conditions as resins & epoxy will not cure correctly, even if you manage to get the repair area absolutely dry which is a problem in itself. Survey work outside becomes difficult as you still need to be as thorough as you would at any time & dark days carry their own problems. For any survey it is imperative that the subject is well illuminated in all places hence the need for a lot of portable floodlight & torch appliances.

 


Ongoing works with timber Wanderer class include a new teak side panels & seats cockpit design & construction.

teak_cockpit

The original cockpit seats and side panels had been removed to undertake major cockpit support structure repairs & were found to be unsuitable for replacement.

 

The design was totally changed to replace plywood with solid teak. The original hinged seats & rigid sides limited the access into the lockers so a removable panel was incorporated to allow good access into the otherwise inaccessible lockers .

New teak gratings & large access panel to engine & teak_cockpit_sidesstern gear in the replaced cockpit sole as previously the aft end of the engine would have been totally impossible to access.

 

 

 

 

 


Most yards have a few vessels that for one reason or another have been neglected for a number of years and forgotten it seems. Occasionally it can be worth enquiring from the yard as to whether a particular "neglected" vessel could be purchased if it is the sstern-planks-fittedtype of boat you are looking for but didn't think you could ever afford the "ready to go"version. Sometimes the owner will be only too happy to be tempted with the offer of clearing the expenses and responsibility of a vessel they no longer use. Just bear in mind the potential pitfalls of purchasing a boat that has not been used for a considerable time. Decay, distortion and deterioration can destroy your dreams withseized engines top of the list.

A neglected Hillyard in Poole. & (below) How it could look

Two examples of the same class of boat and there is no reason why the neglected Hillyard could not be the same as the two below (one is 9 ton the other is 12 Ton). However, having said that, a lot of work and a clear understanding of what is wrong and what has to be done is needed.

Timber has a unique range of possible problems that many surveyors feel ill at ease in understanding. No surprise as few timber boats are built and most surveyors only experience GRP hulls and GRP courses. The main areas of concern on timber construction are those that most people are aware of, decay.
Below: anode related damage to planking. the timber just dropped away leaving a 1.5" dia hole where the anode bolt was.
anode_damageHowever, there are various forms of decay that few are aware of.The most destructive decay beneath the waterline is electrolytic decay. This is very different from what the majority of people understand is decaying which is usually a result of freshwater contamination long-term culminating in bacterial decay such as you get in fence posts in the ground, rotted window frames on houses etc.
Electrolytic decay can be so expensive as to make the vessel uneconomic to repair. Sadly it can be induced by some surveyors who insist that anodes are fitted and wired up. The mere fact of doing this can cause major decay within the stern end of the vessel where the anode is wired internally and to the planking at the position of the anode. As the anode works in protecting the metal a chemical builds up around the metal which physically destroys the timber. Whenever you see a white crud or powder internally at the position of an anode or anode wiring then you can be sure that a form of electrolytic decay is occurring and the wood beneath the crud has started to go soft or will be soft. This can occur where rudder tubes go through the stern of the vessel and quite often is connected with the internal stern gear and stern tube. If the damage is too severe, the repairs can run into many thousands of pounds. However, these are not the only areas where timber vessels can suffer.
Sometimes it is more a case of prioritising some areas. It is not likely there is a timber vessel of any age that does not have some potentially structural faults. However, then mind that not all structural faults require immediate repair and some can remain for decades without any concern.
Many boats will have the odd broken frame without any long-term consequence. It is up to the surveyor using their own experience and judgment as to what is important and what is not so important. That is why, when choosing a surveyor for a timber vessel, choose someone who has long-term experience of timber boat ownership, repair and understanding of how a timber boat is built.

GRP Build supervision & surveys.click open When Seafish/MCA receive new fishing boat applications for boats under construction, in the caser of GRP the hull has to be checked as the vessel is being built.
Some over 7m will require 4 surveys in bulid. One in the mould checking the frame & structrural components with regard to size and position, one when the boat is out of the mould to check the hull external moulding and hardness (barcol). Internally the boat is checked for bulkheads and sealed deck. Another two surveys for what is called outfit, this is the engine, bilge pumps, steering and so on as all of these items have particular requirements depending on the type of vessel. The standards that apply to these vessels can cross over into yachts quite easily with a degree of practicality.

Survey cost advice. How to save on insurance survey costs. click open Many insurance companies will accept an update of a previous survey which can be a lot less expensive than a full insurance survey. It is also possible that some may accept a simple "Safety Inspection"
This covers just the primary important sections of the vessel. Not all surveyors will tell you this or undertake this type of survey. It can save a lot of money. Check with your insurer first before booking a more expensive full survey . It might be that you want to know as much as possible in which case a full survey is the best option. Safety items include steering, basic hull integrity, seacocks, fire fighting, immediate crew safety,Gas installations, firefighting, bilge pumps and anything that constitutes an obvious risk.
An update includes all of the above but with the added information of any deterioration or completed recommendations in the original survey which I would have to have a copy of .
Depending on the insurer they will occasionally accept an update of about 6 years after the original registered report
Just occasionally it can be found that if you try negotiating with the insurers, they relent on the requirement for a survey at that time. It is worth remembering though, if there is a subsequent claim that derives from what the insurers see as "lack of maintenance" then you will not have a successful claim whatever you think you are insured for. Never rely on the insurance as a back up for something you know needs looking at.

We are much more than just surveyors

Having a survey is a win win situation
Unless the vessel is new, you will need some sort of survey to satisfy and secure insurance cover. It is always best to survey before purchase rather than after. A comprehensive survey will often show up problems and faults the owner was not aware of. This provides a valid reason to negotiate the asking price to cover faults discovered during the survey. If the survey shows no faults then you have peace of mind knowing you have that very rare item : a boat with no problems.

Put your mind at ease
So many surveyors use examples of Super-yachts they have surveyed in order to build confidence in their skills. We can do super-yachts but much of the survey work we undertake is on yachts from 15ft to 50ft.
A survey carried out by Seasurveys will tell you if the vessel is suitable for the intended purpose, safe and a good investment.

Key assets you need in your surveyor

  1. Approachability in explaining what items will show up on a survey on a vessel.
  2. Jargon free reports
  3. Helpful with type of survey selection
  4. Flexibility with additional services that may be required depending on the situation of the vessel to be surveyed

Always insist on seeing a sample-survey from more than one surveyor. Not all reports are comprehensive...
