      Ok,

      Been through all pics on the boat list and can’t find a GRP hull that looks like this one (Hull and Deck are GRP).

      Main track runs onto sidedeck and shaped side decks rules out Seamark Nunn and no makers marks on it (or hull number anywhere apparently sail number on sail was not for boat).

      Can anyone identify who made this hull and if they were any good? Where they fast? Built well? More suitable for heavy sailor? Quicker to plane? Any info at all?

      Also does the mast look like a boyce or needlespar, seller says mast is a holt alan but don’t thn they made them and it looks like a delta section

      John,

      i don’t recognise this at all.
      Its deff not seamark nunn, dont think its a hendriksen either. It does look quite well laid out – probably a one off. i would put it on the scales. if it is close to weight, its worth spending some effort to get it on the water.
      cheers

      Not got the boat,

      I thought looks well laid out as well,

      It’s for sale, but again very cheap, and trying to figure out if it’s any good. Unusual for an all GRP to be a one off but not unknown.

      Just not got a hull number so can’t see if it was ever measured as not sure travelling to weigh it is a very good or practical idea…

      Have fingers crossed someone will recognise it. Looked through class rules and can’t see any reason having the mainsheet track where it is would be a problem (disadvantage to sitting forward but advantage of useable track).

      Be great to find out what the heck it is just for interest etc.

      John

      Sail number (not hull number) is 1364 so must be an old one off the OK at south staffs (Adrian Walker ownes, prev owner of 1364 was Chris Rhodes)

      Ok been looking about and have decided on two options here….

      It’s a GRP hull that the deck was knackered on and was repaired and altered by a local boat builder. It was a prototype from a boat builder that doesn’t make ok’s or it was a prototype from someone who altered their design for production or a very low volume boat from abroad so not anymany about and especially in UK.

      Decided now without doubt it ain’t a seamark Nunn with customre-worked deck (unless they did a mk3 prototype). My deduction here is the shape of the centreboard case which looks original is very different to a seamark hull. The cleats and mast etc that are on the boat makes me think this was probably an 80’s boat (just a feeling I get) any earlier and reckon track and control layout would look wrong, forward position of track, mainsheet to floor etc.

      Think shape of the centreboard case may give us a clue if it’s a one off from a make that did ply decked grp boats or mostly did a different deck design.

      Will keep my detective work going

      Well this does look to be a mystery

      Gonna pop some stuff on ebay and if I get enough I will take this one. If a little heavy it should still make an ok starter hull. Will also have a good look about and see how stiff or not hull feels, If it feels stiff I will get this ready for water as well and see whether orange one or this one sails the best. Will also look at mast step positions and see if it’s designed for wood or alloy mast (may give us a handle on age etc.)

      How on earth do I measure hull weight???

      The large Hatch Covers suggest the hull is 70s, they dissapeared early eighties when they changed the bulkhead rule

      Ah right, Nice one…

      Still, depends on use… and by design, condition etc. it looks like it has been looked after.

      Will go and have a look once stuff sold on ebay

      Would like two semi decent ones for me and daughter.

      Which fits with 1364 having been first registered in January 1970

      Yeah but sail 1364 doesn’t belong to this boat. It’s sailed at south staffs and looking at events it’s been used quite recently.

      Think 1364 was a GRP hull and Ply deck seamark. Looked at pics post 2009 and it is still a ply deck boat (plus seller said previous owner said 1364 sail didn’t belong to the boat).

      So don’t think the number fits.

      And looks like rudder is a 15deg so guess was sailed seriously at some point
