A Photo & Discussion Forum for Wharram Design Enthusiasts
I've found a tiki 30 for sale and considering to buy it but, the boat wasn't build by plan and I am much puzzled about the engineering and structural strength. The boat is made of fiberglass over foam. Problem 1) There are 7 aluminium beams 100 mm x 50 mm rectangular hollow section 6 mm wall, 4' x 2' x ¼. fiberglassed straight to the hulls, three of them are also bolted. My concern here is that the aluminium covered by the glassing cannot be checked and aluminium oxide could form unseen and deplete the strength of the beams. Is the section of this beams adequate?
Problem 2) the beam at the bow holding the trampoline is made of a 50mm diameter pipe, 2'. It seems to me that this pipe is too small and will crash at the very first time the bows dip in and scoop water up. Right or wrong?
Problem 3) at the stern, a board has been placed across from hull to hull, half way up from the WL to the beam in order to facilitate boarding. Wouldn't this board splash hard on the water when the boat is pitching?
Any suggestions are much appreciated.
Too many modifictions on one boat. Not good deal. Scott Brown have one good Tiki 30 for sale...see:
Thanks Rogerio. I think you are right. Too many modification to the original plan and they don't seem to be neither improvements nor reliable to me. Would much appreciate the comments of other Wharram knowledgeable people as, I need to justify my offer to the owner. That boat needs a all refit to the deck and beams and my offer will be accordingly.
Thanks for the link, looks very interesting but I am in Australia. A bit too far.
Asta la vista
You welcome...I don't know how much you wanna spend, but here have one good Tangaroa in Adelaide
Graças Rogerio. Eu acho que você está certo. Muitos modificação ao plano original e eles não parecem ser nem melhorias nem confiáveis para mim. Seria muito aprecio os comentários de outras pessoas conhecedoras Wharram como, eu preciso justificar a minha oferta para o proprietário. Que o barco precisa de uma reforma tudo para o convés e vigas e minha oferta será de acordo.
Obrigado pelo link, parece muito interessante, mas eu sou da Austrália. Um pouco longe demais.
Asta la vista
Thanks Rogerio. The Tangaroa 37 in Adelaide and the Tiki 30,discussed in this thread, are the 2 I am considering. Thanks Shaun. You surely have hit the nail in the head here. I am a boat builder with many miles on the clock but don't have the verbal skills you do. English is not my mother language. I tried to explain to the owner all the wrong things of his boat and my offer was accordingly to cover the work to rebuild the beams and deck to specs. the owner has taken it as an insult. As you say the beam at the bow and the boarding plank can be removed and are not dramma but, those beams, fiberglassed straight to the hulls are a total nonsense. A recipe for troubles, a disaster to come. I have 35 years of sailing experience and gone through a few of those treacherous conditions the sea is capable of and my imagination runs wild, thinking of that boat in those conditions.
Yes Shaun, I am cautious.
