Well, I did it:

pirateboat.lua

local topos = {x=133, y=362, z=7, stackpos = STACKPOS_TOP_CREATURE}

local keywordHandler = KeywordHandler:new()
local npcHandler = NpcHandler:new(keywordHandler)
NpcSystem.parseParameters(npcHandler)

function onCreatureAppear(cid)			npcHandler:onCreatureAppear(cid)			end
function onCreatureDisappear(cid)		npcHandler:onCreatureDisappear(cid)			end
function onCreatureSay(cid, type, msg)	npcHandler:onCreatureSay(cid, type, msg)	end
function onThink()						npcHandler:onThink()						end
-- OTServ event handling functions end

function creatureSayCallback(cid, type, msg) 
    if(not npcHandler:isFocused(cid)) then
        return false
    end

if msgcontains(msg, 'boat') or msgcontains(msg, 'transportation') or msgcontains(msg, 'pirate') or msgcontains(msg, 'helmet') then
 
	selfSay('Give me my Royal Helmet', cid)
	if getPlayerItemCount(cid, 2498) > 0 then
		if getPlayerSlotItem(cid, 6).itemid == 2498 then
			selfSay('You really want to go?', cid)
			talk_state = 1642
		else
			doPlayerSendTextMessage(cid,MESSAGE_INFO_DESCR, 'Put the helmet in your right hand, below you necklace slot.')
		end
	else
		selfSay('You don\'t even have a royal helmet !', cid)
	end
elseif talk_state == 1642 then
	if msgcontains(msg, 'yes') then
		local pos = getCreaturePosition(cid)
		doPlayerRemoveItem(cid, 2498, 1)
		doTeleportThing(cid, topos, TRUE)
		doSendMagicEffet(pos, CONST_ME_ENERGYAREA) 
	elseif msgcontains(msg, 'no') then
		selfSay('Well, ok.', cid)
	end
talk_state = 0
end
end
npcHandler:setCallback(CALLBACK_MESSAGE_DEFAULT, creatureSayCallback)
npcHandler:addModule(FocusModule:new())

PirateBoat.xml:

<?xml version="1.0" encoding="UTF-8"?>
<npc name="Pirate Shipmaster" script="data/npc/scripts/pirateboat.lua" walkinterval="16000" floorchange="0" access="3" level="1" maglevel="1">
	<health now="150" max="150"/>
	<look type="134" head="67" body="86" legs="76" feet="57" addons="3" corpse="2212"/>
	<parameters>
		<parameter key="message_greet" value="Hello |PLAYERNAME|, I can take you on my boat to the pirates islands if you give me a royal helmet." />
	<parameter key="message_farewell" value="YAAARRGH !" />
	</parameters>
</npc>

Just change the looktype so it look like a pirate

YAARRGH !

Tell me if it worked
