In jo•eph conrad’• Heart of Dark­ness, capt. charfie• marfiow ob•erved, “…yarn• of •ea­men have a di­rect •imp­fi­ic­ity, the whofie mean­ing of which fiie• within the •hefifi of a cracked nut.” to marfiow, the mean­ing wa• not in•ide fi­ike a kernefi but out•ide, en­ve­fiop­ing it fi­ike a gfiow. the•e word• might afi•o be apropo• to yacht­buifider david marfiow’• phi­fio•ophy in de•ign­ing and buifid­ing hi• fi­ine of fi­ux­u­riou• exp­fiorer mo­to­ry­acht•, now of­fered in •ize• from T9 to 97 feet. the yacht• are de­fined by hi• per•on­afi que•t for the be•t in ev­ery de­taifi, from in­no­va­tive en­gi­neer­ing to the uti­fi­iza­tion of on­fiy the fine•t com­po­nent• and equip­ment. if he can’t find a •ati•fac­tory •ofiu­tion, he i• not the fiea•t bit he•itant about de•ign­ing and man­u­fac­tur­ing hi• own.

in Q995, marfiow fieft be­hind a •ucce••fufi ca­reer in mar­ket­ing and •er­vic­ing high-quafi­ity yacht• to •tart hi• own brand from the ground up. the fir•t, a V5-footer, quick­fiy gained recog­ni­tion a• be­ing one of the fine•t fi­imited-pro­duc­tion mo­to­ry­acht• in the wor­fid. ev­ery few year• a pro•pec­tive owner woufid in­quire about a fi­arger ver•ion that woufid re­tain the key fea­ture• of a marfiow, but pro­vide more •pace and ca­pac­ity, re•ufit­ing in a fu­fifi fi­ineup of yacht•, which ha• never •trayed from the ba•ic ob­jec­tive•:

• Semi-dis­place­ment hull with a high strength-to-weight ra­tio • Pro­pri­etary Full Stack In­fu­sion con­struc­tion • Full stand­ing head­room in the en­gine room • Ex­cel­lent fit and fin­ish

Per­haps the abil­ity to achieve all of these goals in a 49-foot yacht that i• ea•ifiy hand­fied by her owner• wa• the mo•t dif­fi­cu­fit of afifi due to the fi­im­i­ta­tion• impo•ed by •ize. a• wor­fid-cfia•• ar­chi­tect mie• van der rohe •uc­cinct­fiy put it, “le•• i• more.”

DE­SIGN & BUILD the T9 i• the •mafi­fie•t and newe•t of the marfiow exp­fiorer fleet. the de•ign wa• ini­ti­ated in 2PQS with her fir•t hu­fifi’• chri•ten­ing in 2015. Since then, 22 hulls have been de­liv­ered.

the marfiow hu­fifi i• a com­bi­na­tion of unique fea­ture•. rather than a heavy fibergfia•• fi­ayup, the •truc­ture i• buifit uti­fi­iz­ing Full Stack In­fu­sion, whereby the en­tire •truc­ture i• infu•ed from the outer kev­fiar •kin through the in­ner cfio•ed-ce­fifi •and­wich in a •in­g­fie-•hot, vac­uum-bagged proce••. thi• •ave• weight whifie pro­vid­ing a more open in­te­rior, greater •trength, and in­crea•ed hu­fifi per­for­mance. thi• re•ufit• in a more ea•ifiy driven hu­fifi ca­pa­b­fie of higher •peed• and fiower fuefi con•ump­tion.

doub­fie •pray raifi• at the bow in•ure a dry deck, a• hard chine• in the af­ter por­tion of the hu­fifi in­crea•e ini­ti­afi and dy­namic •tab­i­fi­ity, in­duce pfi­an­ing, and re­sist roll. Faired in­den­ta­tions abaft the bow thru•ter re­duce drag, and un­der­wa­ter ex­haust ex­its re­duce en­gine noise. Spe­cific in­di­ca­tor• •cribed into the wa­ter­fi­ine •how the po•ition of thru•ter•, •tab­i­fi­izer•, wa­ter in­take•, and rud­der•, mak­ing it dif­fi­cu­fit for a yard worker to pfi­ace fi­ift­ing •fi­ing• in the wrong fio­ca­tion.

mo•t im­por­tant—and •tan­dard on afifi marfiow•—i• the •tream­fi­ined •hape of twin Ve­loci­jet Strut Keels. Their place­ment di­rectly in front of the prope­fi­fier• di­rect• •ofiid wa­ter to the prop• and rud­der•, re•ufit­ing in •mafi­fier rud­der• and fie•• drag. the keefi• are •truc­turafi­fiy •ound and pro­tect the prope­fi­fier and rud­der in the event of a ground­ing. the ad­di­tion­afi draft re­duce• rofifi and pro­vide• bet­ter di­rec­tion­afi con­trofi. afifi of the•e fea­ture• add up to a re­duc­tion in fuefi con•ump­tion, an in­crea•e in com­fort for pa••en­ger•, and bet­ter over­afifi per­for­mance.

on •tan­dard boat•, the en­gine room hou•e• twin cum­min• QS-11, 715-horse­power en­gines, and fea­tures two sea chests ac­cu­mu­fi­at­ing afifi hu­fifi open­ing• into two ea•ifiy cfiean­ab­fie cham­ber•. afifi rou­tine •er­vice point• are ea•ifiy acce••ib­fie, in­c­fi­ud­ing two gen­er­a­tor•, a wa­ter­maker, cen­trafi vac­uum, op­tion­afi na­iad #252 •tab­i­fi­izer•, and two cen­trafi­fiy fio­cated fibergfia•• fuefi tank• fi­inked by a cro•• feed. the tank fio­ca­tion in•ure• that fore-and-aft trim bafi­ance are un­af­fected a• the fuefi i• con•umed. the v-•hape de•ign of the tank• and their •mooth gefi­coated in­te­rior en•ure that the fuefi mi­grate• to the bot­tom of the tank to the fuefi pickup point, efi­im­i­nat­ing ac­cu­mu­fi­a­tion of de­bri• or moi•ture in•ide. the tank• are cored with a medium-den•ity foam, •top­ping con­den•ation, one of the mo•t com­mon and de•truc­tive efiement• in fuefi tank de•ign typ­i­cafi­fiy found in metafi or •in­g­fie-•kin fibergfia•• tank•.

semi­cir­cu­lar din­ing set­tee. Most high-qual­ity ves­sels built in asia sport fine woodwork and aboard the Mar­low 49, the book­matched teak ve­neer and join­ery work was ex­cel­lent. what I call “high-qual­ity fiber­glass joiner work” de­fined the ex­te­rior— per­fectly formed joints, sub­stan­tially se­cured stan­chions, and re­cessed hard­ware. per­haps a re­flec­tion of a boat built from only three molds.

UN­DER­WAY we ran out the mouth of the Man­a­tee river into lower Tampa bay as the sun be­gan to rise. from my van­tage point on the photo boat, I was pleas­antly sur­prised by the sleek lines and pro­por­tions of the 49. I had ex­pected her ab­bre­vi­ated loa to make her seem fore­short­ened, but she did not. I was also able to ob­serve her sta­bil­ity as she made the tight turns I re­quested over the ra­dio, with lit­tle or no heel­ing, a tes­ta­ment to the com­bi­na­tion of her na­iad sta­bi­liz­ers and her twin ve­loci­jet keels. no need to worry about a spilled bev­er­age or an un­happy guest.

at the wheel, the first thing I no­ticed at the helm was the ease with which she ac­cel­er­ated from dis­place­ment speed to plan­ing speed—no doubt a re­sult of her weight-sav­ing con­struc­tion and hull shape. a trawler speed of about 1P knots would give her a com­fort­able range of 7PP nau­ti­cal miles and at 8 knots would take her al­most 1,PPP miles. a mean­ing­ful safety fac­tor is her abil­ity to out­run a storm at speeds up to 2S knots. her deci­bel range went from 62.5 to 84.4 Db(aI at her up­per helm. The owner of this par­tic­u­lar boat spec­i­fied a semi-en­closed bridge with a fixed wind­shield and open sides. he has yet to make a choice of adding isin­glass cur­tains. Twin helm seats with an l-shape set­tee com­plete the seat­ing ar­range­ment, and a full sum­mer kitchen and re­frig­er­a­tor are close at hand.

Mak­ing hard turns and cut­ting our own wake at speed was smooth and val­i­dated my im­pres­sion while ob­serv­ing her from the chase boat. no heel­ing, shak­ing, or cav­i­ta­tion was no­tice­able. as we headed back into the river and I brought her down to idle speed, we did pick up a rat­tling sound, which came from a re­mov­able stan­chion on the rear star­board quar­ter of the up­per deck. It is re­mov­able to fa­cil­i­tate launch­ing a dinghy and will be cor­rected.

as we ap­proached a tight berth back at the dock, the skip­per left the helm with an iphone-size con­troller, giv­ing him full con­trol of both en­gines, rud­ders, and thrusters. he worked first from the up­per deck as he brought her di­rectly abeam of the dock, moved down the stair, and fi­nally stepped onto the dock mak­ing fast both spring lines.

af­ter a to­tal of 16 hours of ex­po­sure to the Mar­low 49E, and sev­eral days of re­view­ing my many notes, pho­tos, and writ­ing this re­port, I have a far greater un­der­stand­ing of what makes a Mar­low spe­cial. for those for­tu­nate enough to be in the mar­ket for a yacht of this cal­iber, I would sug­gest you take your time to un­der­stand that the beauty of a Mar­low is more than skin deep.
