    Having just picked up my latest GP14 from Ulverstone and got her safely home to Norfolk (nervewracking trip down A590, M61, M62, A1M, A17, A47) after sharing the three lane highways in constant rain and road spray with 42 tonne lorries all the way, I hope to begin researching my new cruiser/club racer with the help of members and the Association archived history. She is an all fibreglass boat with moulded mahogany gunwhale rubbing strakes, 3 mahogany bench strips over foam buoyancy hull mouldings each side and mahogany thwart fastened to centreboard case and each side. Sail number if they are not second hand is 12493. I’ll begin looking for a makers/moulders plate on the hull somewhere once I’ve removed the floorboards, but a bit too wet to start that job at the moment …

    Well done;   now enjoy!

    Very tentatively,  the mahogany parts suggest that she might be a Mk. III GRP boat,  and if the sail number is correct it seems to be consistent with that.

    Some photos,  particularly of the internal arrangement,  would be helpful.

    Thanks Oliver for your very prompt reply and welcome. That should be TWO mahogany bench strips either side and moulded buoyancy hull tanks under bow deck and side benches. The mast has no spreader and is stayed with shrouds through deck, with Cunningham but no kicker and a full transom mainsheet traveller. Still can’t find a maker/moulder’s plate, but have included 3 photos which didn’t go from my phone so hopefully will load this time.

    …and the third internal

    …and yet again another fairly identifiable feature is the transom tiller aperture which is a slightly vee’d oblong 100mm high and 130mm wide at top and 100mm wide at bottom, complete with chips at bottom either side where tiller has obviously been shoved over rather hard! … I’m on the GP14 yahoo open members forum by the way but there seems no way to search either that or the International class association  forum by subject, so as yet have had no joy finding anything definitive which may identify my boat or maker.

    The photos are a slight puzzle.

    The presence of a moulding for a full width sheet horse (track) rules out her being a Mk III,  and that feature would seem to suggest either Mk I or Mk II.   I am fairly confident that she is NOT a Mk I,  because I don’t see the alloy tubes which serve as frames in those boats;    but a second identifying feature of the Mk I model is a single stern buoyancy tank right across the boat beneath the stern deck.

    Thus far the presence of the moulding for a sheet horse would seem to suggest Mk II,  in which case the sail number is incorrect (i.e. the sail is likely to be a second-hand one,  and the number was not changed when the sail was used on this boat).   The first of the Mk III boats was produced in 1977,  with sail number 11487.

    However the raised moulding beneath the side benches and also the centreboard case do not look quite like the Mk 2 boats that I remember having seen.   Additionally,  a common identifying feature of the Mk 2 boats is curved “vertical” boxed sections of GRP,  of rectangular horizontal cross section,  between the side buoyancy tanks and the underside of the deck;  and your boat does not have these.

    My best guess,  but I am very willing to be corrected by anyone who knows their GRP GP14s better than I do,  is that she may be a Mk 2 but built by Thames Marine,  or just possibly by McComb Boats,  rather than Bourne Plastics.

    According to the definitive text,  Roy Nettleship’s Brief History of the GP14 Hull,  “Thames Marine supplied their boats fully fitted out and ready to sail and built about 260 boats with sail numbers between 8012 and 9314.   About 50 hulls numbered between 10682 and 11325 were built in Northern Ireland by McComb Boats,  at first using Thames Marine moulds and later a set acquired from Bourne Plastics.”

    I have long been under the impression that the Thames Marine boats had a thumb wheel stainless steel adjuster for the centreboard friction device,  on the side of the centreboard case (starboard side?).   However I am not 100% sure about this,  nor about how definitive it is even if I am right.

    Hope this is of some help.

    Brilliant and knowledgeable, hope you’re in robust good health as this stuff is invaluable and we need to get it in a database for posterity! Your specific references to makers and to the Nettleson history are particularly useful for my further research. Never quite understood why there should be so much history easily available to car owners, but such patchy documented stuff for boats. And by the way, there’s a GP14 on eBay at the moment, “Dolphin” in Gwynedd, which looks very like mine. Many thanks for your considered replies.

    Roy Nettleship’s article mentioned appears in 50 Years on the Water,  which is an anthology published by the Association in year 2000 to mark our 50th anniversary.   New copies are long since sold out,  and of course it is out of print,  but second-hand copies are sometimes still obtainable via the usual second-hand book dealers;   there is one copy currently listed on Amazon,  at a price,  and not many years ago I found several copies offered,  so more may yet appear again.

    A scanned copy appears on this site,  and also on the GP14 Owners Online Community site.

    As a further detail,  amongst the Mark II boats those produced by Thames Marine were heavily outnumbered by the Bourne Plastics boats,  and the McComb boats were even more heavily outnumbered.   That is a likely reason why the Mark II boats with which I am most familiar have all been Bourne Plastics boats.    I then noted the unusual features of your one,  and thence made an educated guess;   but it remains no more than an educated guess.

    If Dolphin in Gwynedd is indeed the same configuration as yours I am definitely going with Mark II;   and in my view almost certainly not by Bourne Plastics.    That does seem to confirm Thames Marine as the most likely builder.

    However there are others around,  perhaps most notably Steve White,  who know far more about the early GRP boats of the class than I do.
